Different organic supplements are considered as essential treatments for improving the soil nutrients status and hence raising productivity of soils in vast areas all over the world.
Since chemical fertilizers are becoming highly costly and the use of extremely high rates of chemical fertilizers could lead to soil pollution (FAO, 2018), the use of organic fertilizers may help in augmenting soil fertility and contributing in decreasing the cost
