The effect of Interaction between Compaction and agricultural sulfur on Availability and uptake of some nutrients and growth of Corn Plant (Zea mays L.)

Abstract

This experiment was conduted to study the effect of stress caused by Soil Compaction on Agricultural Sulfur oxidation and their interaction effects on availability and uptake of some Nutrients (N, P, K, Fe, Mn, Zn, Cu) and their relationship on Corn plant growth (Synthetic Var.106).Agriculture Sulfur was added to the Clay loam soil Classified Typic Torrifluvent at three levels 0, 1, 2, MgS˚. hg1 (S0, S1 and S2) respecrively than it was compacted to following bulk density levels 1.25, 1.35, 1.45, 1.55 Meg/m-3 (B1, B2, B3 and B4) respecrively .Results indicated significant affect for compaction on the studied growth indexes (plant height, leaf area, Root and Shoot dry matter) also on the uptake of (N, P, K, Fe, Mn, Zn, Cu).The uptake of these nutrients were positively up to 1.35 Meg.m-3 . then it showed negative effect as bulk density level was increased. We showed that addition of the Sulfur significantly increased availability of nutrients and growth indexes when it was addition at level S1 increased up to S2. N, P, K and Cu uptake significantly affected .But Zn, Mn, and Fe uptake were not affected. S2B2 treatment was showed best values for studied indexes. Incompertion to the S0B4 tyreatment which showed lower values.
