A GI would mean that only the argan oil prepared from seeds collected in Morocco, with the appropriate rules of production, could be sold as such under that name [7]. Soak argan seeds in water for four days before planting. The agroclimatic indices, which determine different classes of suitability, were integrated in a Geographic Information System (GIS) to create thermal and moisture regions. Argan tree plays a vital role in maintaining the ecological balance and the economic situation of the population. To prevent lethal effects, the annual mean minimum temperature (that represents the long-term average daily minimum air temperature observed during a calendar month and over the year) cannot be lower than −5°C [18]. This could affect the argan oil business in Morocco and defeat the efforts initiated to save the argan forests. Polyunsaturated fatty acids constitute approximately 80% of argan oil, and 30% of it is linoleic acid. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground. However, if dairy cattle are fed with the cake, it contaminates the milk, and this may cause diarrhoea in children. These types of trees, in their indigenous areas, take up in order to 39 inches of rainfall each year. Maximum temperatures never surpass 30°C and the minimum of the coldest month is never below 7°C [25]. For now, we have found an excellent farmer who supplies us with our Argan fruit. Classes of agroclimatic suitability and limits for each class. If this coppicing is done with sufficient knowledge of species and local conditions, the tree will respond by growing new shoots from its roots. The argan tree life span frequently exceeds 200 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. They will tolerate irrigation with brackish water. The argan tree used to grow throughout North Africa, but today it only grows in southwestern Morocco. From the Souss plain to the Anti-Atlas Mountains, annual precipitation is in the 250 to 150 mm range. The climate is more extreme than in Agadir, with a distinct continental character. This model may be applied in any part of the world, using the agroclimatic limits presented in this paper. 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]. In some regions, it is already damaged, and its future is endangered by prolonged drought periods and desertification. The agroclimatic suitability map presented is indicative because climate data spanning 30 years was used rather than data for a specific year. Annual rainfall is scarce (232 mm) and concentrated from October to April. If you are lucky enough to live in one of these tropical climes, knowing how to grow macadamia trees successfully can provide you with a lifetime supply of these desired nuts. This zone, considered suitable, is influenced by the north wind year-round, which is responsible for the high temperatures over the year. In Figure 8 the mean annual minimum temperature of −5°C is shown. Based on international bibliography, the authors outlined an agroclimatic zoning model for this tree in Argentina. 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”. It grows wild in semi-desert soil and is extremely well adapted to drought and other environmentally harsh conditions. Climatological characteristics of its region of origin were considered to evaluate the requirements and biometeorological conditions. I have only a few seeds left. The international price of argan oil has stimulated the idea of cultivating A. spinosa in regions far from its original geographic center [7]. In less than a century, more than a third of the argan forest has disappeared. Argan oil was used in Berber folk medicine for centuries to treat skin conditions, rheumatism, and heart disease. Brightening. Argan Tree. The limit between the subhumid and semiarid zones is represented by the 500 mm isohyet. They are thorny, with gnarled trunks and wide spreading crown. These isolated populations are considered relicts of a wider distribution in the past [5]. The successful … 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. Step 3 Water your argan tree during the summer if its soil is in danger of drying out. Any grass or bushes in the area of the tree's shade can also die from direct exposure to the sun. 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.
