Abstract
A field experiment was conducted at Ismailia Experimental Research Sta ion to study the residual effect of compost and btc-ccmposue manures applicalio on sandy soil properties and Egyptian clover yield. whereas the previous yield 'f3s soybean. The experiment design was randomized complete block with four rePliffies. The sandy soil was treated at the previous summer season with the foil ing treatments: control. 4. 6. 8 ton compost /fed., 4 and 6 ton bio-composite Ifed. Egyp ian clover seeds were sowing with two agriculture melhod .. arrange row and dispersal.
The obtained results revealed that the high effluence on sandy soil physical properties rendered to the residual effect of 6 ton bio-compositelfed. application were hydraulic conductivity and bulk density decreased and tolal porosity increased.
In proportion to the effect on fresh and dry clover yield. this &tudy proved hat the I)ighest rate or bio-composite (6 tonlfed.) led to the maximum increase for cutS as well as total yield. Moreover. the residual effect at bio-composite addition gav •• llhe best results for N, P and K clover plant uptake.
Eventually. the arrange row agriculture method led to an increase for lotal clover yield with 12.9 % for fresh weight and 24.6% for dry weight. compared1with dispersal egriculture methods.
