The Effects of Farmyard Manure and Green Manure Applications on Some Soil Physical Properties

Abstract

In this research was carried out to determine the effects of farmyard manure and green manure applications on some physical soil properties in an organic vegetable cultivation field. The effects of control (C), farmyard manure (FYM) (35 t ha-1) and green manure (GM) applications on some soil physical properties (Soil water characteristics (0.001, 0.1, 0.33, 1, 5, 10 and 15 bar), available water capacity, porosity and bulk density) were investigated for soil depths of 0-10 and 10-20 cm and for two years. In the study at all tension values, the highest volumetric soil water content was obtained for FYM application and the lowest volumetric soil water content for C application. The highest total porosity with macro and micro porosity were found in the FYM application and the lowest total porosity with macro and micro porosity were found in the application C. The available water capacity was the highest in the GM application and the lowest in the C application. In addition, the highest bulk density was found in C application and the lowest bulk density was found in FYM application. These results showed that the effects of different organic material applications on soil physical properties are important.
