Water control is a major problem in crop production, particularly in fragile
ecosystems such as the Sahel. Water is the most important factor in plant
productivity. Many initiatives have been developed in this direction, including
all methods of irrigation and water and soil conservation. The objective of
this work is to assess the effectiveness of this amendment in crop production
in the context of climate variability. The methodology is based on experimentation
to statistically compare the natural biomass on a soil of silty-clay-sandy
texture, divided into two blocks, one of which is amended with potassium
polyacrylate and the other is not. This study showed that the wet and dry
biomasses produced on soils with potassium polyacrylate are significantly
higher than those produced on unamended soils at the 5% threshold. Based
on these results, potassium polyacrylate may be a solution to recurrent dryness
pockets. However, uncontrolled environmental testing is necessary to
confirm these results.
