| Abstract |
Two field successive experiments were conducted in Ismaillia Research Station to study the effect of natural soil amendments application on soil physical properties and yield of peanut (c.v. Giza 5) and carrot (c.v. Local). The first experiment was carried out to evaluate the effect of organic manure (rice straw compost and chicken manure) mixed with clay minerals (bentonite and vermiculite) on peanut yield and soil physical properties. Each mineral was added to the soil at a rate of 7 ton/fed., while organic manures were added at a rate of 5 ton/fed. The second experiment was carried out to evaluate the residual effect of soil amendments on soil physical properties and yield of carrot. The results showed that added different organic manures to the soil improved its physical properties. Addition of rice straw compost or chicken manure to soil decreased bulk density and increased total porosity compared to the soil without organic manures. Hydraulic conductivity decreased by addition of natural amendments to soil while soil field capacity increased. In the second season organic residues decreased bulk density and hydraulic conductivity and increased total porosity. The most important results indicate that soil amendments improved soil moisture retention in the following order: chicken manure mixed with vermiculite> chicken manure mixed with bentonite > compost mixed with bentonite>compost mixed with vermiculite. Also results showed that the yield of peanut and carrot increased significantly by natural amendment application compared to no amendment application condition. However, the highest yields of peanut and carrot were obtained with the application of chicken manure mixted with vermiculite followed by chicken manure mixed with bentonite and compost mixted with bentonite. The lowest value of yield of the two crops was obtained from adding compost mixed with vermiculite
