| Abstract | ||||
| A field experiment was carried out on a sandy soil of the Experimental Station of Agric. Rese. Center (ARC), Ismailia Governorate, Egypt to study the effects of using some crop residues as a natural soil conditioners on some physical properties i.e., bulk density, hydraulic conductivity, field capacity, wilting point and available water and chemical properties (pH, EC and the content of O.M) and available N, P and K as well as the productivity of (Zea mays L. c.v., Triple hybrid 324).The experiment was designed in a randomized complete block design with three replicates. The three sources of soil conditioners were: sawdust (S), rice straw (RS) and maize stalks (MS) at rate of 2.5 g O.C/ kg soil. Also of two rates of nitrogen mineral 5 % and 10% over the N Recommended dose (300 kg/fed which added as ammonium sulfate (21% N). Obtained results can be summarized as follows: | ||||
