Study on the Effects of Organic Fertilizer Application in Different Crop Systems on Soil Nutrients,Yield and Quality
The application of additional organic fertilizer is a crucial link in promoting green cultivation and circular agriculture.To fully explore the effects of organic fertilizer on soil nutrients,crop yield,and quality in different crop systems,a comparative study was conducted by adding organic fertilizer on top of the normal application of chemical fertilizer.This involved monitoring the changes in various indicators and systematically discussing the yield and quality changes of different crops.The results showed that the applica-tion of organic fertilizer had a significant effect on improving soil fertility.Soil organic matter,as well as available nitrogen(N),phos-phorus(P),and potassium(K),increased by 48.26%,32.97%,74.67%,and 26.69%,respectively.Crop yields increased under the addition of organic fertilizer,with the largest increase observed in fruit trees,at 11%.Yields of wheat,maize,and rice increased by 2.22%,2.43%,and 2.64%,respectively.In terms of improving fruit tree quality,the application of organic fertilizer significantly in-creased vitamin C(Vc)content,which was 12.5%higher in fruits than in those without organic fertilizer application.However,there were no significant changes in the content of soluble solids and titratable acidity.This study has high guiding significance for the ra-tional application of organic fertilizer in different crop systems.
