Abstract
Pot experiment was carried out using sandy soil samples which were
collected from the surface soil (O-20Cm) of Tahrier region. The experiment was
designed in complete randomized with three replicates. The first factor was organic
matters as FYM at the rate of 200 gm/pot (20ton/fed), sodium humate 50 mg/pot (5
Kg/fed) and potassium humate 80 mg/pot (8 Kg/fed). The second factors was ferrous
sulfate 7,14 mg/kg soil (7.14 kg/fed).
The dry matter yield of corn plants significantly increased by using organic
adsorbent alone or combined with iron compared with control. The best results of dry
matter yield were obtained as follows: FYM > K - H > Na - H > control at all iron
levels.
Nutrient contents (N,P,K and Fe) in corn plants increased with applying of
organic adsorbents for all treated iron levels Similar trends of results were found as
for the dry matter yield of corn plants.
Residual effect of N,P,K and Fe in soil after harvest of corn plants, generally
increasing the nutrient extractable from soil. This increase for N,P and Fe was follows:
FYM > Na- H > K - H > control. Only K extractable was in this order: FYM > K - H >
Na - H > control.
