Abstract

In Cambodia, soil capability for rice production in lowlands has been almost documented, but only little is known about the properties of upland soils for growing non-rice crops. Current agricultural land use practices together with severe climatic conditions and population pressure have led to soil degradation, loss of soil fertility which declining crop yield and increase the risk of malnutrition. Therefore, the objectives of this study were 1) to compare the soil properties of farmlands applied organic and inorganic fertilizers, 2) to measure the organic fertilizer dependence in Samraong and Baray Communes. The questionnaire survey was conducted and farmer representatives were interviewed. Soil samples were collected from 20 different locations. Soil samples were analyzed for its pH, Electrical conductivity (EC), organic matter, total nitrogen (T-N), total phosphorus (T-P), calcium (Ca²⁺), potassium (K⁺), sodium (Na⁺), water content, and permeability, and the Pearson coefficient correlation was used for the statistical analysis. Organic fertilizer dependence was classified into 3 categories not dependent, moderately dependent and highly dependent, 40.0%, 30.0%, and 30.0%, respectively. The results of statistical analysis showed that in Samraong Commune there was no trend detected, despite in Baray Commune there was positive trend detected between organic fertilizer dependence and soil properties.
