Change in physico-chemical properties of soil and nutrients in Desmodium triflorum in case of seasonal variation in Ratnanagar-11, Jirauna, Chitwan, Nepal

Background Physico-chemical change is described in case of seasonal variation. The plant became grazed in different seasonings; nitrogen, phosphorus and potassium are estimated. The aim of paper is the nutrient uptake of Desmodium triflorum due to the change in season.

Methods The sample is collected as four month interval period the grass is tolerate as low pH. N-1.67–2.04%, P- 0.34–0.61% and K-1.46–4.15%.

Results Soil had lowest concentrations of nitrogen (0.096%), phosphorus (0.004%), and potassium (0.027%) in the rainy season. The highest concentration of nitrogen (0.22%) occurred in summer season, phosphorus (0.005%) in winter and summer seasons, and potassium (0.073%) in the winter season. The carbon/nitrogen (C/N) ratio was highest (15.22:1) in summer and lowest (13.96:1) in the rainy season.

Conclusions Present study will be valuable in evaluation and management of the middle land pastures in Nepal.
