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.
