The Effect of N,P and K Fertilizer on the Nutrient Uptake of Smooth Vetch

Open publisher page 1 citations

Abstract

The effects of the application of nitrogen,phosphorus and potassium fertilizer on the nutrient uptake of smooth vetch were studied under pot experiment.The results showed that the influences of the application of nitrogen and potassium fertilizer on the nutrient content and nutrient uptake of smooth vetch were not significant;while the influences of the application of phosphorus fertilizer on the nutrient content and nutrient uptake of smooth vetch were significant.The application of a little nitrogen and more phosphorus fertilizer in the soil with high available potassium content could promote the absorption of nitrogen and potassium in the process of growth of smooth vetch.
