Evaluation of compost influence on soil water retention

Abstract

The experiment was focused on evaluation of influence of compost application on soil water retention. Soil retention is a major soil water property that governs soil functioning as a ecosystem. Soil moisture forms a major buffer against flooding, and water capacity in subsoil is a major factor for plant growth. The effects of changes in soil water retention depend on the proportions of the textural components and the amount of organic carbon present in the soil. During seasons of 2009 and 2010, experiments at two sites of different soil conditions prepared by addition of compost doses of 50 and lOOt.ha-1 were carried out. Changes of humidity were continuously monitored and recorded by soil moisture sensors. Results showed that application of compost of above mentioned doses positively affected water retention of the soil. Organic matter, applied at the above mentioned amount has a positive effect on soil moisture retention, regardless of possible influence of soil type, grassing and amount of rainfalls. Outcomes of experiment become bases for recommended compost doses as well as for technical proposal of compost application processes.
