Organic materials play a critical role in sustainability in the arid and semi-arid regions. Despite this importance, there is little predictive understanding for the management of organic inputs in arid and semi-arid agroecosystems. It is now widely recognized that SOM plays an important role in soil chemical (pH, base saturation, salinity and CEC changes) and physical (bulk density, stabilization of soil structure and aggregate formation) properties. In this study, the influences of farmyard manure (FYM) applications on some physical and chemical properties of the soil were investigated. This study was conducted between October 2000 and April 2001 in greenhouse as a pot experiment with a Lithic Rhodoxeralf. Treatments included four rates of FYM as follows on a dry weight basis: 0, 10, 20 and 40 t ha(-1) After seven months incubation period, soil organic matter (SOM) contents, total nitrogen (N), soil pH, electrical conductivity (EC), cation exchange capacity (CEC), base saturation (BS) and bulk density (BD) were determined. The effect of FYM applications on SOM, total N, pH, EC, CEC and BD were found to be significant (p<0.001), however, the effect of FYM on BS was not significant. The use of FYM led to an apparent increase, especially in intermediate and high doses, in SOM, total N, pH, EC and CEC but to a slightly decrease in BD. The use of FYM can contribute to enhancing the level of organic matter in Lithic Rhodoxeralf, which is particularly poor in organic matter under greenhouse condition.
