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 soil physical properties in a three yearly 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 bars), available water content, porosity and bulk density) were investigated in 0-10 and 10-20 cm soil depths for two years. At all tension values, the highest volumetric soil water contents were obtained for FYM application and the lowest ones for C treatment. The highest total porosity along with macro and micro porosity were found in the FYM application and the lowest ones were found in the C application. The available water content 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.

Effect of biogas waste applications on soil moisture characteristic curve and assessment of the predictive accuracy of the Van Genuchten model

“…In their study on the effects of organic material applications on water retention and water-entry value, Liyanage and Leelamanie (2016) reported that the soil water content significantly and linearly increased with increasing organic material content. Again, Müjdeci et al (2020) reported that stable manure and green manure applications increased volumetric water content at all retention pressure. Barzegar et al (2002) stated that organic material applications increased the water content held at levels below 100 kPa.…”
