argan tree growing conditions

According to [21], the winter mean maximum temperature should be higher than 17.5°C. eubiona.com Traditionnellement, l'huile d'argan s'obtient par la pression manuelle des amandes du fruit de l'arganier. The tree is in threat of extinction due to clearance, poor germination quality, and the use of the timber as fuel. Brightening. The successful … The argan (Argania spinosa L.) belongs to the Sapotaceae family and it is the only species of the genus Argania. Choisissez parmi des contenus premium Argan Tree de la plus haute qualité. However, research on these plants is usually scarce because they are commonly wild nondomesticated species. It adapts well to hostile environments, and it can even be irrigated with salt-rich water [29]. Some isolated populations can be found northeast of Morocco, 400 to 700 km away from the main ones: in Berkane in the northern slope of the mountain Beni-Snassen, close to the Mediterranean coast (800 ha), and in the Bou-Dreg plains (Kariat Arakmane), in the eastern Rif of the high valleys of Oued Grou, close to Rabat (50 ha) [2]. These were obtained by interpolating the data collected in the 125 meteorological stations across the country (National Meteorological Service). They are thorny, with gnarled trunks and wide spreading crown. Germination does not occur with temperatures below 10°C, and the optimum germination temperature is 25°C [16], with night temperatures above 21°C [17]. These trees do not really even mind if … According to [13], the argan tree prospers in desert or arid (Bw), steppe or semiarid (Bs) climates, between 20 and 32° latitude. From the Souss plain to the Anti-Atlas Mountains, annual precipitation is in the 250 to 150 mm range. The climatic requirements and tolerances of the argan tree have been outlined in relation to the environmental conditions of their natural habitat. It will take … If rainfalls are below 100 mm, the area is deemed marginal under rainfed conditions and in the 100–200 mm range, it is a suitable area. To identify regions with appropriate bioclimatic conditions for cultivating A. spinosa, both winter and summer requirements must be considered, since resistance to frosts and drought can be the key to success. It is a little-known tree indigenous to intramontane areas, with very low average rainfall, in southwestern Morocco. The dietary and nutritional properties of argan oil are superior to those of extravirgin olive oil. In the 100 to 200 mm and 300 to 400 mm interval, the area is suitable and, from 200 to 300 mm, optimal. The argan forest is particularly sensitive to climate change and it was ignored as a specific biotope for a long time. Efforts are being made to introduce and evaluate the potential of argan tree (Argania spinosa L.) a native of Morocco, for greenery applications under Kuwait’s environmental conditions. In the areas with agroclimatic suitability (suitable and very suitable), this index is between 3.5 and 7°C. According to [4], it appears in subspontaneous form in the Sahara, between Djebel Ouarkziz and the Hamada of Tindouf (Algeria), in humid microhabitats. Basic data in determining this similarity were the amount of annual rainfall, the annual temperature, the annual minimum temperature, the winter maximum temperature, the minimum temperature of the coldest month, the mean annual minimum temperature, and the annual maximum temperature. One of these areas is Admine Forest (hereafter Coastal Browsing, 30°26′54.13′′N and 9°32′49.90′′W, located in the suburbs of Agadir city, 5 km inland, 107 m of altitude), which different authors [22–24] consider as the ecological optimum for the species and the center of its distribution area. The great inflection towards the south in the province of La Pampa, due to the continentality factor, is noteworthy. Age Defying Apricot Probiotic Cleansing Milk. Afterwards, these were processed by the Geographic Information System (GIS) tool of the Arc-GIS 9.3 program. It contains the haemolytic saponin sapoarganine, which is slightly toxic but does not harm ruminants. To the extent that the species is unable to withstand cold, the annual mean minimum temperature, the winter mean maximum temperature, and the minimum temperature of the coldest month were analyzed. Argan tree (Argania spinosa) seeds are the source of argan oil, which is used as a cooking oil and in the cosmetics industry. The argan is a species that can be cultivated in drylands in regions where annual rainfalls are in the 200–300 mm range, with a minimum of 100 mm and a maximum of 400 mm [13]. This can be a race against the clock – goats often climb the trees, eating the harvest first. Argan Biosphere Reserve extends over 2.5 million hectares in the semi-desert of south-western Morocco. There are no optimal zones for the argan tree in Argentina. Some of them are in the following countries: Algeria (1.33°N/36.16°W), Netherlands (52.25°N/5.60°E), USA (34.14°N/118.05°W and 34.00°N/118.00°W). argan trees influence the soil underneath significantly, while the soil in intertree areas is less protected and more degraded. An optimal area can be identified to the west of the country and another one in the Patagonian region. However, Discover Life [26] cites the species in a larger latitudinal range. Apart from the economic value, Argan trees play a huge role in the natural ecosystem. Under arid conditions there is another area classified as suitable with constraints which covers parts of the provinces of San Mendoza, San Juan, and La Rioja. For now, we have found an excellent farmer who supplies us with our Argan fruit. The altitudinal range of the argan tree extends from sea level up to 1,300–1,500 m. The annual rainfall varies from 250 mm in Safi to 400 mm in Agadir. The tree flourishes in areas where annual mean temperatures fluctuate between 18 and 20°C. Macadamia nut trees can begin bearing in 6 to 7 years, so it is important … In a way, they are similar to the mangrove trees that are preventing floods in the area they grow in. Argan tree plays a vital role in maintaining the ecological balance and the economic situation of the population. 2018, Article ID 9262659, 10 pages, 2018. https://doi.org/10.1155/2018/9262659, 1Climate and Water Institute, INTA, Las Cabañas y Los Reseros, s/n, Castelar, Buenos Aires, Argentina, 2Laboratorio de Cultivo Experimental de Plantas y Microalgas, Departamento de Biodiversidad y Biología Experimental, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Buenos Aires, Argentina, 3Instituto de Micología y Botánica (INMIBO), Universidad de Buenos Aires-CONICET, Buenos Aires, Argentina, 4Centro de Investigaciones y Estudios Ambientales (CINEA), Facultad de Ciencias Humanas (FCH), Universidad Nacional del Centro de la Provincia de Buenos Aires (UNICEN), Campus Universitario, Paraje Arroyo Seco, s/n, Tandil, Argentina. Figure 3 presents the annual mean temperature >18°C. Best growth is observed with temperatures in the 20–30°C range, with a minimum of 10°C and a maximum of 35°C, although it can tolerate maximum temperatures of 50°C. Figure 5 presents the areas where the annual mean minimum temperature is above 10°C. The maps were obtained using a series of previously interpolated bioclimatic variables. The effects of different treatments, such as container type, planting medium and seed … However, if the purpose is production of edible oil, these areas could qualify as suitable with complementary irrigation. These are usually the result of climate variations, and even slight changes in a single climate element can wield important influences. To define the suitable zones, studies must focus on whether the agroclimatic availability of an area can satisfy the biometeorological demands of this species. These trees are warm region plants only, but growing macadamia nuts in southern California and other areas with tropical climates is possible. To the east, another suitable area can be recognized, and it receives annual rainfalls in the 300–400 mm range. The GBIF [27] cites only 34 occurrences with georeferenced data. A suitable area with constraints under dry-subhumid regime is present in the center of the provinces of Catamarca and Salta. Notwithstanding, this is pioneering work because the agroclimatic zoning for the argan tree in Argentina has never been done before. image caption The argan tree is native to Morocco We are in the Moroccan countryside, some 25km (15.5 miles) inland from the port city of Essaouira, halfway down the country's Atlantic coast. The plant is distributed across five Moroccan provinces (the most important ones are Agadir, Essaouira, Toroudant, and Tiznit), in arid and semiarid ecosystems, with Atlantic influence, between 29° and 32° of north latitude [1, 2]. As can be observed in Figure 9, there is no optimal agroclimatic area for argan cultivation because, in the optimal zone, the minimum temperature of the coldest month is never below 7°C [25]. O. M’Hirit, M. Benzyane, F. Benchekroun, S. M. El Yousfi, and M. Bendaanoun, D. Rivera and J. Argan Tree Icon Argan Tree. Currently, the olive industry has been curtailed due to rising production costs (approximately 40% annually) and low foreign currency (dollar) values. Argan trees can be grown from seed and can survive temperatures down to 19 degrees Fahrenheit. Water your argan tree during the summer if its soil is in danger of drying out. A very suitable area was described, which covers a large portion of the province of La Rioja and a small part of Catamarca. Its manufacture is a strictly family activity, not even a small-scale production by craftsmen. Suitable areas cover part of the north and the center of the country, and the east of Argentina. These researchers maintain that argan tree is one of the few surviving relict-breed species of the Tertiary Period, which spanned from 65 million to 1.8 million years ago. Review articles are excluded from this waiver policy. CannaCell® Sensitive 1000 Roses® Quenching. The color is darker and the odor stronger than argan cosmetic oil because of the previous toasting of the kernels. Near Essouira, Morocco - E028EB from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Shop the range. In the optimal zone, the minimum temperature of the coldest month must never be below 7°C [25]. First, we had to identify the requirements, limits, and biometeorological tolerance and conditions to establish the potential growing areas. He is the author of several guidebook chapters and the complete "Sunshine Guide" guidebook to Gran Canaria. Argan cultivation could reconvert the olive areas by interspersing argan and olive trees to reach a more lucrative production per hectare. In some parts of Morocco, goats can be found perched on the branches of argan trees, nibbling away at their fruit and leaves. 2 The argan tree The argan tree of the family Sapotaceae is only endemic in Morocco, where argangrovesnaturally coverabout8000 km2. The species needs neutral soils (pH of 6.5 to 7.5) and, although soil quality is not an issue, drifting sands and water-logged soils must be avoided. Down Icon Down. Considering the increase in arid conditions worldwide, together with the prediction for fewer rainfalls, argan trees could be used for greenery purpose and to reduce climate change effect. Silvia L. Falasca, Sandra Pitta-Alvarez, Ana Ulberich, "The Potential Growing Areas for Argania spinosa (L.) Skeels (Sapotaceae) in Argentinean Drylands", International Journal of Agronomy, vol. The white seeds contain up to 50% of light brown oil, and oil production ranges between 1000 and 2000 tons per year. Download this stock image: Fresh Argan nuts growing on an Argon tree. By creating an account you agree to the Hunker, Purdue University Extension: New Crops as a Possible Solution for the Troubled Israeli Export Market, Food and Agriculture Organization of the United Nations: Argania Spinosa. Another index is the annual mean maximum temperature, which should surpass 23.0°C to ensure an appropriate thermal regime during the growing period [14]. In the future, farmers could combine horticultural species cropping, some olive trees, vegetables and livestock (mainly goats) in association with the argan tree, and beekeeping. The wood is hard, heavy, and durable, and it results in good charcoal and firewood. The successful introduction of this species in Argentina depends essentially on the degree of similarity of climate in the natural area to that of the new areas with agroclimatic suitability. This can lead to more soil erosion and desertification. Eight classes of suitability were delineated: very suitable, suitable, suitable area with constraints (under dry-subhumid, semiarid, and arid regime) and under irrigation, marginal, and nonsuitable areas. The argan (Argania spinosa L.) tree is indigenous to southwestern Morocco. Scarce and scattered spiny shrubs are the main woody vegetation. Although Argentine territory extends towards the Tropic of Capricorn (23°27′S), it lacks tropical climates. … In fact, it’s a specialized plant that’s only native to one area. Argan oil is rich in unsaturated fatty acids and vitamin E. The tree is native to southern Morocco, where it grows in open forests up to an altitude of more than 5,000 feet. Maximum temperatures never surpass 30°C and the minimum of the coldest month is never below 7°C [25]. Natural vegetation is scarce, except for the dominant A. spinosa, and the climate is temperate due to marine influence. Summer is particularly harsh because temperatures are inordinately high and rainfall is scant (385 mm) and almost totally absent. Investors, on the other hand, frequently fail because they lack adequate information concerning the risks and uncertainties related to these ventures. In Morocco's southern mountains gold grows on the region's argan trees. In the summer months, water the Argan tree, particularly if you know that the soil it is planted in is about to dry up. This isotherm indicates the southern limit for warm climates that can still be appropriate for tropical crops. The climate system of a particular place defines the crops that can be developed. The nuts are later collected by farmers to produce oil. Plant the seedlings in a mixture containing three parts soil to one part peat moss and one part humus. For instance, they sometimes put at risk the sustainability of the ecosystem where implantation is purported, or they ignore the agroclimatic requirements of the species. Occasionally, new crops with attractive properties and exploitation potential capture the attention of both public and private sectors. The north and northeast present optimum conditions with an average temperature of 7°C, while the suitable area (where minimum temperatures in July range from 3.8 to 7°C) covers the center of the country and reaches the center of the Buenos Aires province. Argan is perfectly adapted to the region’s harsh environment, with the ability to survive extreme heat (over 50°C), drought and poor soil. The limit between the subhumid and semiarid zones is represented by the 500 mm isohyet. A threat to the argan forests. It was introduced for cultivation into Algeria, Israel, Kuwait, Libya, the semiarid Southeast Spain [10], and Mexico [6]. Consequently, argan can be used as a repopulation species in semiarid and arid zones. This composition is particularly adept for nutritional, cosmetic, and medicinal uses. This research was supported by the National Council of Scientific and Technical Research (CONICET) of Argentina. An agroclimatic zoning model was developed. These areas have regular drought periods, which could be mitigated by argan tree since it not only provides forage for goats but also produces argan oil for local consumption and for sale. This could affect the argan oil business in Morocco and defeat the efforts initiated to save the argan forests. The tree is an important source of forage for sheep, goats, and cattle, but horses reject it. Argan trees grow in poor soil in their native habitat, according to the University of Arizona's Campus Arboretum website, and are not fussy about soil quality. Put water unto the soil mixture, sufficient to make the soil moist. The argan tree (argania spinosa) is found exclusively in Morocco, particularly the south-western region. This index is a very important constraint, because lower temperatures can be lethal to argan tree. FAO, “Ecocrop,” (1993-2007) Available at: F. Bani-Aameur and J. Sipple-Michmerhuizen, “Germination and seedling survival of Argan (Argania spinosa) under experimental saline conditions,”, Y. Mizrahi and A. Consequently, damage by frost should be avoided when tropical species are exploited. There are no optimal zones for the argan tree in Argentina. It is therefore reasonable to assume further degradation of the soil when intertree areas extend further due to lack of rejuvenation of argan trees. C. Orwa, A. Mutua, R. Kindt, R. Jamnadass, and S. Anthony, “Agroforestree Database: a tree reference and selection guide version 4.0,” 28 December 2015, Z. Charrouf and D. Guillaume, “Argan oil: occurrence, composition and impact on human health,”. Argentina’s political map, with the toponomy of the provinces, was included to aid in the identification of the classified areas with different grades of agroclimatic fitness (Figure 1).

When it is lower than 17.5°C a nonsuitable area is delineated; in the 17.5 to 22.0°C range the area is suitable, while temperatures above 22°C define marginal areas. The women who are doing this work, call for a better salary and fair living and working conditions." As a result, many growers have ceased investing and olive farms have been abandoned. Currently, the tree can be found in the south of Morocco, west of Algeria, north of Western Sahara, and north of Mauritania [9]. The 18°C isotherm covers north and part of the center of the country. Peltier, G. Carlier, and A. El Aboudi, “Evolution journalière de l’état hydrique des feuilles d’arganier (Argania spinosa L. However, if dairy cattle are fed with the cake, it contaminates the milk, and this may cause diarrhoea in children. The rest of the citations correspond to Morocco (30,53°N/7,89°W, 30,79°N/8,38°W, 29,70°N/9,92°W, 30,82°N/8,40°W, 30,68°N/8,17°W, 29,42°N/9,44°W, 30,37°N/9,70°W, 30,62°N/8,09°W, 29,75°N/9,28°W, etc.). These isolated populations are considered relicts of a wider distribution in the past [5]. The following classes were delineated: very suitable, suitable, suitable with constraints (under dry-subhumid, semiarid, and arid regimes), suitable with constraints under irrigation, marginal, and nonsuitable. In this article, you’ll learn a great deal about the argan tree. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The nut-shells are also burned for cooking. Skeels.) A suitable area with constraints under irrigation is in the provinces of San Juan, La Rioja, and Catamarca, and small ones can be found in Mendoza and San Luis. Classes of agroclimatic suitability and limits for each class. Argan oil presents an exceptional percentage of essential fatty acids, one of which is linoleic acid (omega 6, the most essential of all) ensuring the functions of repair and defence of the skin. These are areas with mostly lithosols and regosols soils, associated with saline soils on lowlands. The suitable areas cover the eastern and center part of the country. Geographical location, mean annual rainfall, and temperature records available from meteorological and agrometeorological stations within the study area were also considered. Alex Bramwell started writing in 2002 and spent six years in the field of writing and editing news reports in the business, finance and technology sectors. To create the maps, a series of previously interpolated bioclimatic variables were used. The suitable and very suitable zones delimited for argan in Argentina are characterized by low and variable rainfall (100 to 400 mm) and mild winter temperatures. Monthly average temperatures are 40°C in summer and 3°C in winter; but they can drop to −5°C. The limits were delineated by the 100 and 400 mm isohyets [13]. There is a marginal area in the north due to the high winter temperatures. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground. The argan tree used to grow throughout North Africa, but today it only grows in southwestern Morocco. The fruit has a green, fleshy exterior that ripens to a bright yellow. Argan oil was used in Berber folk medicine for centuries to treat skin conditions, rheumatism, and heart disease. A very important factor is the species’ resistance to cold, since it can hinder its cultivation in a specific area. Polyunsaturated fatty acids constitute approximately 80% of argan oil, and 30% of it is linoleic acid. This model may be applied in any part of the world, using the agroclimatic limits presented in this paper. The average maximum winter temperature ranges from 17.5°C to 22°C [21]. Bramwell holds a Bachelor of Science with honors in zoology from the British University of Reading. This agrees with the agroclimatic zoning map presented in this paper, since the suitable area reaches the north of San Luis province (approximately 33°S). The agroclimatic suitability map presented is indicative because climate data spanning 30 years was used rather than data for a specific year. Keywords: soil erosion; argan; South Morocco; soil degradation; tree; intertree 1. To achieve this, both the thermal and the moisture regime, which are fundamental climatic characteristics that affect the development of this crop, must be considered. Table 1 shows some climatic characteristics of area of origin of the argan tree. Nonsuitable areas, whose minimum temperature of coldest month is lower than 3.8°C, cover the west, the center, and the Patagonian sector. The argan tree is a slow-growing spiny tree and is either shrubby or up to 10 m high when isolated and growing in a favorable environment [2]. Argan is a thermoxerophile and its edaphic requirements are scarce [28]. Starting in Essaouira and extending to Goulmime, and from the High Atlas to the Atlantic Ocean, it covers more than 828,000 ha [3]. Argan Tree. In this work, a set of long-term averages, covering a range of climate elements, for the period 1981 to 2010 was assembled. The land is bordered by the Sahara, the High Atlas, and the Anti-Atlas Mountains between Essaouira and Agadir Ida Outanane and open to the Atlantic on the west side. It can also be found in certain parts of the Spanish Levante in Alicante. Grow argan from seed planted in 3-inch plastic pots. The agroclimatic indices, which determine different classes of suitability, were integrated in a Geographic Information System (GIS) to create thermal and moisture regions. The resulting maps were superimposed to determine the agroclimatic zoning. Materials and fuels . Botanically, Argan is a relic species from the Tertiary Age, the only member of the tropical Sapotaceae family occurring north of the Sahara and the single species of the genus Argania. Considering that the species has not yet been introduced into Argentina, the climate of its original area was studied in detail. Figure 2 shows the moisture regions. Slightly larger than an olive, the argan fruit is usually harvested in July and August once it falls to the ground. In some regions, it is already damaged, and its future is endangered by prolonged drought periods and desertification. Argan trees in nature receive up to 39 inches of rain per year. In its path, it shows an inflection towards the north owing to the Pampeanas Saws located in the provinces of Córdoba and San Luis. For example, it mentions a preserved specimen in Arizona, USA, at 34.5°N/111°W; in Spain at 37.5°N/9°W, 38.21°N/10.25°W, and 40.5°N 3°W; in United Kingdom at 52.5°N/3°W; in Kenya at 1.5°N/39°E; and in Morocco at 31.5°N/9°W and 31.5°N/3°W. This is responsible for the low minimum temperatures in all the national territory. As a result, fruit production extends over a long period and fruits can be found in different ripening phases from April to September [3] in the north hemisphere. Soak argan seeds in water for four days before planting. Germination takes up to a month. The argan tree is a very resistant tree of the arid regions, whose roots grow deep in search of water and thus help retain the soil, preventing its erosion and limiting the advance of the desert. The agroclimatic zoning map was obtained by superimposing the maps related to moisture and thermal regimes. Argan trees that do not receive enough water will go into dormancy and not produce any fruit. The argan tree does not exist in Argentina and, consequently, there are no commercial plantations that can be used to compare the agroclimatic zones delineated in this paper. The suitable and very suitable areas for argan largely coexist with the Argentine olive tree cultivation region. According to [13], the tree dies with frosts of −2°C, although according to [18] it can tolerate −5°C. Edible argan oil has several sterols that are uncommon in other edible vegetable oils, such as scotenol (48%), which has antitumoral and anticancer properties, and spinasterol (42%), a compound that reduces intestinal cholesterol absorption. The values which best indicate the thermal requirements of this species and can be used as equivalents are the bioclimatic variables: annual mean temperature, annual mean maximum temperature, annual mean minimum temperature, winter mean maximum temperature, minimum temperature of the coldest month, mean annual minimum temperature, and annual rainfall. The extreme eastern limit of the country is located at 53°38′W, in the town of Bernardo de Irigoyen (province of Misiones). The area situated between 500 and 1000 mm/year presents a subhumid climate, and the climate is humid when it exceeds 1000 mm. This zone, considered suitable, is influenced by the north wind year-round, which is responsible for the high temperatures over the year. This index represents the average of the maximum temperatures from June to August, over the 30-year period considered. The highest boundary for argan tree is close to the 3.8°C isotherm, which corresponds to the lower limit for snow [2]. The oil is also used for illumination and soap. Figure 7 shows the minimum temperature of the coldest month (July). The aim of this work was to design an agroclimatic zoning model to define the potential growing areas for Argania spinosa in Argentina. Step 3 Water your argan tree during the summer if its soil is in danger of drying out. The 10.0°C isotherm diverts to the south influenced by the oceanity factor, which is conspicuous in the province of Buenos Aires. It is a region traditionally used for agriculture and livestock raising. Most crops commonly show recognizable differences in many of their properties within their area of distribution.
