Evaluation of soil conditions of Maidhiya pond of Birganj (Nepal).

摘要

Soil conditions of Maidhiya pond (Birganj, Nepal) in relation to fish were studied during 2006 and 2007. Soil chemistry of this pond was found to be within the range of normal condition for aqua-culture process especially the fish culture. Favorable pH range, comparatively high phosphate content during monsoon and presence of moderate amounts of organic compounds were observed on the soil analysis of this pond. Organic carbon content of this pond remained in the range of moderate productivity being higher during post-monsoon and winter seasons. The potash content of the soil was highest during monsoon season might be due to inflow of this mineral along with the water from the adjoining areas.
