argan tree growing conditions

The argan tree life span frequently exceeds 200 years. The first index used to analyze the thermal factor was the annual mean temperature, measured over a period of 30 years. 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]. 3. In the 100 to 200 mm and 300 to 400 mm interval, the area is suitable and, from 200 to 300 mm, optimal. Plant the seedlings in a mixture containing three parts soil to one part peat moss and one part humus. Choisissez parmi des contenus premium Argan Tree de la plus haute qualité. The extreme eastern limit of the country is located at 53°38′W, in the town of Bernardo de Irigoyen (province of Misiones). According to [13], the argan tree prospers in desert or arid (Bw), steppe or semiarid (Bs) climates, between 20 and 32° latitude. The argan tree (argania spinosa) is found exclusively in Morocco, particularly the south-western region. Argan is a thermoxerophile and its edaphic requirements are scarce [28]. It grows wild in semi-desert soil and is extremely well adapted to drought and other environmentally harsh conditions. Currently, the olive industry has been curtailed due to rising production costs (approximately 40% annually) and low foreign currency (dollar) values. The nut-shells are also burned for cooking. In the optimal zone, the minimum temperature of the coldest month must never be below 7°C [25]. Macadamia nut trees can begin bearing in 6 to 7 years, so it is important … 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. Soak argan seeds in water for four days before planting. A threat to the argan forests. For this reason, the Moroccan government seeks to obtain a Geographical Indication (GI) on argan oil [8]. This area, considered suitable, reveals how the incoming cold air from the Polar Front projects to the north. Most crops commonly show recognizable differences in many of their properties within their area of distribution. The successful … Brightening. Currently, the argan tree is found in an intramontane area with very low average rainfall. It later diverts to the north because of the altitudinal effect imposed by the Andes Mountains. 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 wood is hard, heavy, and durable, and it results in good charcoal and firewood. We are committed to sharing findings related to COVID-19 as quickly as possible. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground. The tree is also popular as a shade tree and it is useful for soil conservation and windbreaks. An agroclimatic zoning model was developed. 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]. To the south, in desert areas, precipitations are considerably lower than 100 mm [2]. The argan (Argania spinosa L.) belongs to the Sapotaceae family and it is the only species of the genus Argania. 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. They will tolerate irrigation with brackish water. In 1999, Unesco added the argan tree to the World Heritage list. 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]. The area studied was the Argentine Republic. However, Discover Life [26] cites the species in a larger latitudinal range. For this reason, two extreme climatic areas were chosen to describe the “argan bioclimate.”. Grow argan from seed planted in 3-inch plastic pots. Natural vegetation is scarce, except for the dominant A. spinosa, and the climate is temperate due to marine influence. Finally, Figure 9 (obtained by overlaying all the above-mentioned maps) presents the agroclimatic zoning for the argan tree. given the absence of necessary conditions in terms of soil structure, moisture, fire limitation, and types of seeds.” Southern Moroccan argan forests represent another important example which highlights the effects of human interactions with the local environment and the development of forests too commonly referred to as “wild”. 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. Scarce and scattered spiny shrubs are the main woody vegetation. These types of trees, in their indigenous areas, take up in order to 39 inches of rainfall each year. The oil is also used for illumination and soap. Keywords: soil erosion; argan; South Morocco; soil degradation; tree; intertree 1. He is the author of several guidebook chapters and the complete "Sunshine Guide" guidebook to Gran Canaria. In the coastal areas where argan trees grow, there are temperate oceanic influences with moderate temperatures (annual average in Agadir is 18.5°C; minimum temperature of coldest month: 7.4°C) and low annual and daily thermal amplitude [14]. The area situated between 500 and 1000 mm/year presents a subhumid climate, and the climate is humid when it exceeds 1000 mm. Rainfalls that exceed 400 mm delimit marginal areas for the argan tree. To create the maps, a series of previously interpolated bioclimatic variables were used. The suitable areas cover part of the provinces of Catamarca, La Rioja, Córdoba, and San Luis and small areas in Tucumán, Santiago del Estero, and Salta. Argan trees bear fruit after five years and can survive for 250 years. After the oil is extracted, the residue from the kernels constitutes a thick chocolate-colored paste called “amlou,” with a flavor similar to that of peanut butter. In this work, a set of long-term averages, covering a range of climate elements, for the period 1981 to 2010 was assembled. Argan wood cannot be destructed by insects, and it has been used for centuries in carpentry, charcoal, construction, and utensils at local level. Argan is a saline-sensitive plant [14, 19] and adult trees do not adapt to the higher salinity associated with dry areas. Argan Tree. The tree is an important source of forage for sheep, goats, and cattle, but horses reject it. The fruit has a green, fleshy exterior that ripens to a bright yellow. The suitable and very suitable areas for argan largely coexist with the Argentine olive tree cultivation region. 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. Age Defying Apricot Probiotic Cleansing Milk. Table 1 shows some climatic characteristics of area of origin of the argan tree. Peltier, G. Carlier, and A. El Aboudi, “Evolution journalière de l’état hydrique des feuilles d’arganier (Argania spinosa L. To the west of the very suitable area, there is a suitable area with constraints under semiarid regime that comprises part of the provinces of San Juan, La Rioja, and San Luis. 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. The climate system of a particular place defines the crops that can be developed. Would you like to grow an Aragan tree in your yard? Figure 6 shows the winter mean maximum temperature. The 23°C isotherm covers the north and a large section of the center of the country. 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. Any grass or bushes in the area of the tree's shade can also die from direct exposure to the sun. This model may be applied in any part of the world, using the agroclimatic limits presented in this paper. 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. This zone, considered suitable, is influenced by the north wind year-round, which is responsible for the high temperatures over the year. Clear Skin. 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. 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]. Hunker may earn compensation through affiliate links in this story. Annual rainfall is scarce (232 mm) and concentrated from October to April. The climate of a geographic location can be depicted by long-term averages or “Normals,” which are defined as 30-year averages of a climate element. Geographical location, mean annual rainfall, and temperature records available from meteorological and agrometeorological stations within the study area were also considered. 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. The white seeds contain up to 50% of light brown oil, and oil production ranges between 1000 and 2000 tons per year. Near Essouira, Morocco - E028EB from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Suitable areas cover part of the north and the center of the country, and the east of Argentina. Flowering occurs mainly in spring, with great differences among individuals, and with a secondary peak in autumn. In Morocco's southern mountains gold grows on the region's argan trees. The color is darker and the odor stronger than argan cosmetic oil because of the previous toasting of the kernels. 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. First, we had to identify the requirements, limits, and biometeorological tolerance and conditions to establish the potential growing areas. This can be a race against the clock – goats often climb the trees, eating the harvest first. Sign up here as a reviewer to help fast-track new submissions. It is a little-known tree indigenous to intramontane areas, with very low average rainfall, in southwestern Morocco. 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. … In the areas with agroclimatic suitability (suitable and very suitable), this index is between 3.5 and 7°C. 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 argan tree used to grow throughout North Africa, but today it only grows in southwestern Morocco. To the west of the 500 mm isohyet, the moisture gradient provided by rainfall from the South Atlantic anticyclone decreases and the climate turns dry-subhumid, semiarid, and, finally, arid. These are usually the result of climate variations, and even slight changes in a single climate element can wield important influences. The resulting maps were superimposed to determine the agroclimatic zoning. This index represents the average of the maximum temperatures from June to August, over the 30-year period considered. The climatic requirements and tolerances of the argan tree have been outlined in relation to the environmental conditions of their natural habitat. According to [21], the winter mean maximum temperature should be higher than 17.5°C. 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. The nuts are later collected by farmers to produce oil. 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. If temperatures fall below 18°C the climate is deemed too cold for the argan tree, and the area is not suitable [13]. For the gardener, growing trees indoors may have nothing to do with that, and will mostly just be a challenge to see if they can avoid spider mites on a parlor palm. We look forward to using only our own fruit to make our oil some day. 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 isolated populations are considered relicts of a wider distribution in the past [5]. 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]. Put water unto the soil mixture, sufficient to make the soil moist. The effects of different treatments, such as container type, planting medium and seed … According to [4], it appears in subspontaneous form in the Sahara, between Djebel Ouarkziz and the Hamada of Tindouf (Algeria), in humid microhabitats. The international price of argan oil has stimulated the idea of cultivating A. spinosa in regions far from its original geographic center [7]. 2 The argan tree The argan tree of the family Sapotaceae is only endemic in Morocco, where argangrovesnaturally coverabout8000 km2. It will take … Nonsuitable areas, whose minimum temperature of coldest month is lower than 3.8°C, cover the west, the center, and the Patagonian sector. Argan trees grow to 8–10 m (26–33 ft) high and live up to approximately 200 years. 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. argan trees influence the soil underneath significantly, while the soil in intertree areas is less protected and more degraded. Download this stock image: Fresh Argan nuts growing on an Argon tree. Argan trees that are deprived of water will get into a dormancy condition and won’t bear any fruits. 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. This could affect the argan oil business in Morocco and defeat the efforts initiated to save the argan forests. It usually grows up to 10 m high with a trunk diameter of up to 100cm. The 10.0°C isotherm diverts to the south influenced by the oceanity factor, which is conspicuous in the province of Buenos Aires. As a result, in locations where topographic and geographic traits significantly alter the microclimate, specific areas where the species may be grown could be unknowingly disregarded. Based on international bibliography, the authors outlined an agroclimatic zoning model for this tree in Argentina. This site was selected because it is situated in the proximity of the species’ natural distribution limit. To the east, another suitable area can be recognized, and it receives annual rainfalls in the 300–400 mm range. The agroclimatic indices, which determine different classes of suitability, were integrated in a Geographic Information System (GIS) to create thermal and moisture regions. 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). In the mountains and inside the continent, the thermal amplitude reaches higher values and the minimum temperatures of the coldest month fluctuate from 3°C to 7°C. 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). The 18°C isotherm covers north and part of the center of the country. Nerd, “New Crops as a Possible Solution to the Troubled Israeli Export Market,” in, Z. Bouzoubaâ and A.

Benchekroun, “La dégradation forestière dans le sud marocain, exemple de l'arganeraie d'Admine (Souss) entre,”. It is an open forest where argan is the predominant vegetation type and broad gaps are covered with a grass community. Saadia’s son in law was teaching in a town called Ait Daoud in Essaouira province and he came to know this gentleman well a few years ago. 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 average maximum winter temperature ranges from 17.5°C to 22°C [21]. Age Defying. Different classes of suitability were characterized: nonsuitable, marginal, suitable, and optimal. This index is calculated by averaging the 12 normal monthly temperatures over the 30-year period. 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. 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 country borders to the north with Bolivia, Brazil, and Paraguay; to the south with Chile and the Atlantic Ocean; to the east with Brazil, Uruguay, and the Atlantic Ocean; and to the west with Chile (Figure 1). According to [12], in the period 1970–2007, argan tree density decreased 44.5%. 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.
