Soil properties drastically altered by different land use practices.
The experiment studied how different types of land use affect soil properties. Soil samples were taken from various depths in rice growing and horticultural areas. Results showed that soil pH increased with depth, organic matter decreased with depth, and NPKSZn treated soil had the highest organic matter. Total nitrogen levels varied, with most soils having low to medium levels. Available phosphorus and potassium levels also varied, with most soils at low to optimum levels. Cultivated rice soil had lower potassium content than non-cultivated soil. Wetland cultivation changed soil color to dark gray, while dry land cropping turned it reddish brown.
