Abstract:
This research project aims to assess the effects of different fertilizer application methods on nutrient use efficiency and environmental sustainability. Fertilizer application plays a crucial role in modern agriculture to meet the nutritional demands of crops. However, improper fertilizer management can lead to nutrient losses, environmental pollution, and reduced nutrient use efficiency. This study will involve field experiments, nutrient analysis, and environmental assessments to evaluate the performance of different fertilizer application methods in terms of nutrient uptake by crops, nutrient losses to the environment, and overall environmental sustainability. The findings of this research will contribute to the development of sustainable fertilizer management strategies that optimize nutrient use efficiency while minimizing environmental impacts.
