Abstract We carried out mesocosm experiments using either the anecic earthworm Lumbricus terrestris or endogeic Allolobophora chlorotica and loam, silt loam sandy soils to investigate differing impact of these different ecotypes on aggregate formation (percentage water stable aggregates, %WSA) soil holding capacity (WHC), two properties that underpin many ecosystem services provided by soils. Earthworms significantly increased %WSA (by 16–56% 19–63% relative earthworm-free controls for L. A....
Argania spinosa (L.) Skeels is a unique endemic species in Morocco, renowned for its ecological characteristics and socio-economic importance. In recent years have seen an exacerbation of the harmful effects climate change, leading to alarming decline natural regeneration this original habitats. It seems that only viable solution lies domestication genetic heritage. This study marks first in-depth investigation impact various climatic edaphic factors on morphological physiological traits...
Morocco’s argan trees, native to forests, are now cultivated in large orchards within the Argan Biosphere Reserve, transforming “Arganiculture”. These anticipated bolster carbon storage, but their precise contribution storage remains unclear. This study introduces for first time allometric equations estimating biomass different components of plants orchards. A total 89 plant individuals, aged 2 6 years, were collected. Their diameter and height measured. The biomass, content, stock each...
Climate change, through increased aridity, threatens ecosystems, including Morocco’s endemic Argania Spinosa L. Skeels. This study assesses the impact of aridity on argan trees by analyzing morphological, ecophysiological, and biochemical parameters across various regions comparing them with historical data. Significant variations were observed in leaf area, length, chlorophyll content, relative water polyphenols, flavonoids, soluble sugars, antioxidant activity, while width ratio remained...
This study aimed to investigate the functional response of Panicum antidotale Retz, Chenopodium quinoa, and Zea mays L. different levels saline irrigation water. Nutrient uptake, biochemical content, growth were evaluated select potential crops best suited for biosaline agriculture. The results suggest that blue panicum is highly tolerant water irrigation, followed by quinoa up 10 dS m−1, then silage maize which sensitive conditions. introduction as an alternative crop on salt-effected...
Erosion affects large parts of Moroccan land, particularly in the mountains leading to soil quality deterioration and less vegetation cover.Located South-west Morocco, Site Biological Ecological Interest (SBEI) Ain Asmama, where erosion threatens a major part region was investigated.The site has terraced transitional bioclimate, between arid sub-humid, local conservation importance.The varied, dense, continuous, well-preserved area is crucial protect soils against erosion.Qualitative...
Rainfed agriculture is becoming increasingly vulnerable to climate change. This situation expected worsen under most future projections, which might increase the risks linked food security and economies depend on it. Providing insights about potential responses of rainfed crops change will helps designing adaptation strategies. In this study, large amount data agro-hydrological model SWAT have been used investigate impacts wheat sunflower in a semiarid watershed Morocco (R’dom watershed)....
Salinity is one of the major severe constraints that limit crop productivity in 40% land surface, notably Mediterranean region. In this study, we worked an argan orchard located Laâyoune, Morocco. The characterized by a saline soil and trees are irrigated with highly water. study aimed to evaluate effect irrigation water on oil yield, total phenolic content, flavonoid antioxidant activity, fatty acid composition. results show has no significant yield most quality parameters, yet polyphenols,...
Abstract A composite well-screen has been developed for resistivity measurements using high permeability ‘terran’ fabric wrapped around plastic containing 1.5 mm slots. Laboratory and in situ tests indicate that this screen presents a relatively small impedance to the flow of water electricity while excluding fines may be present. Experiments with were made after emplacement an unconsolidated, dense, fine coastal sand body. Results are presented electrical through well-screen, focussed tool,...
New technologies have been developed to maximize agricultural production with rational use of water resources, especially salt water. We conducted field experiments using either the Nano Irrigation system or drip irrigation on sandy loam soil examine response sugar beet different levels saline Replicates (n = 4) elementary plots, 4 m wide × 5 long two salinity treatments (S1 1.6 dS m−1, S2 6.3 m−1), were established in a factorial design under Irrigation. Soil chemical properties and...
Although earthworms are the key drivers of most valuable ecosystem services and main indicators soil health, existing ecotypes in Moroccan soils largely unknown. The lack records for many regions limited data others is a major obstacle to making sustaining they provide. This study investigates, first time, earthworm biodiversity cultivated 4 irrigated perimeters arid region Souss-Massa. Soil pits (25 x 25 30cm, n = 5) at 40 sampling sites were examined by digging, hand-sorting, using...
