Evaluating the effects of applied mixtures of some organic composts combined with shale on some properties and productivity of

Abstract: The main objective of this investigation was to study the effect of applied mixtures of shale combined with some organic composts of plants residues, i.e., broad bean straw, rice straw and corn stalks at the rate of 20 tons/fed by weight in different ratios (1:3, 1:1 and 3:1), in addition to 50% of the recommended mineral N, P and K fertilizer doses, on some physical and chemical properties of a tested sandy soil at the experimental Farm of Ismailia Agriculture Res. Station as well as the productions of both wheat and maize plants during two successive seasons of 2002/2003 and 2003, as compared to the control treatment (full doses of the recommended N, P and K fertilizers).
Application of different combination ratios (1:3, 1:1 and 3:1) for shale and organic composts improved the physical properties of the tested soil, i.e. clay and silt percentage, bulk density, hydraulic conductivity, total porosity and soil moisture contents at field capacity, wilting point and available water. Also, the chemical properties i.e., pH, ECe, O.M, CEC and available N, P and K in the cultivated soil were favored, except EC as compared with the control due to applying all treatments of shale and such composts together after either wheat or corn harvestings.
The yields of both wheat and corn plants as well as the contents of N, P and K in grains of both crops were markedly improved upon the application of these soil amendments.
In general, the best treatment was a mixture of both shale and composted broad bean, particularly at ratio (1:3) as compared with the other treatments
