Evaluation of compost suitability as a soil amendment [electronic resource].

Includes reference.

Crop trial was conducted compost rate, reaching a maximum for two years under controlled at the rate of 240 t ha- I with no greenhouse conditions to evaluate further increasing at the rate of 360 t compost suitability for amending ha-I, exhibiting a diminishing return. clay soil in terms of both soil physical and chemical properties. Addition of high rates of Significant effects of compost compost to clay soils significantly addition as mixed or surface increased soil pH, O.M%, CEC, andapplication on soil moisture status the soluble salt compared to were noted after each irrigation control. Compared to control, mixed event. The soil moisture content application of compost at high rate was slightly higher in the case of of 360 t ha- I increased the soil EC surface application than mixed from 0.5 dS mol in the control to application. Compost application 4.36 dS mol. This increase in soluble caused significant improvements in salts could be harmful for plant the stability of aggregates compared growth and reduce the yields to control. The mixed application of especially in the case of sensitive compost at all addition rates caused crops. Major consideration in significant differences in the application of compost on clay soils stability of aggregates in comparison is the increase in soluble salts. The to the equivalent addition rates of results of this study revealed that compost as surface application. there are several physical and After two compost applications, the chemical potential benefits of aggregate stability increased applying compost to clay soils in thesignificantly with increasing organic farming systems.
