The soil sampling was done to collect 569 soil samples from Western
Developmental Region, Nepal. Soil organic matter, total nitrogen, available
phosphorus, available potassium and soil pH were analyzed in the soil laboratory.
After the analysis, the soil samples were classified according to organic matter level
in the soil. Among those samples, 63 were high, 250 were medium and 256 were low
in organic matter content. The plant nutrient status and the soil reaction of those
samples were classified as the classification given by Pradhan. The number of the
samples that falls in different categories were calculated and tabulated. Likewise, the
average of soil pH, organic matter content, total nitrogen, available phosphorus and
available potassium were also calculated. The number of soil reaction mostly falls
under acidic group, while most of the soil samples fall under low nutrient status (N, P
and K). The average of the nutrients was higher in the higher organic matter
containing soils than in the lower organic matter containing soils.
