Inorganic fertilizers consume at least one-third of the total energy used by agriculture globally. Increased fertilizer application can increase crop yields and improve global food security, and has potential to eliminate hunger and poverty. Luxury amount of fertilizer application however can contribute to groundwater pollution, greenhouse gas emissions, eutrophication, deposition and disruptions to natural ecosystems, and soil acidification over time. In contrast, insufficient application can decrease crop yields. Both extremes have raised broader concerns regarding soil and environmental degradation, nutrient deficiencies, increased fertilizer costs and decreased profits. To develop practical recommendations for farmers, yield responses to applied fertilizers from inorganic and organic sources, indigenous nutrient supply from soil, and nutrient use efficiency (NUE) require consideration. These factors form the basis of precision or field-specific nutrient management approaches, which could aid in the development of more precise and spatially appropriate fertilizer recommendations. Inadequate knowledge of these factors has constrained efforts to develop precision nutrient management recommendations that aim to rationalize input costs, increase yield and profits, and reduce environmental externalities.
Over the years, advances have been made in understanding the crop yield response to fertilizers and NUE in varying farmers’ management practices. However, small farmers in many countries still think fertilizers are expensive inputs and degrade soils, and thus the policy makers want to promote organic fertilizers instead of inorganic fertilizers. There is lack of sufficient scientific understanding regarding the need and benefit of inorganic fertilizers over organic fertilizers to meet nutrient demand of high-yielding crops. A balanced application of inorganic and organic fertilizers maybe be advocated to increase yields and profits, and reduce soil and environmental degradation.
This Special Issue will focus on “Fertilizer Application on Crop Yield”. We welcome papers resulting from novel and innovative research, reviews and opinion pieces covering all related topics including inorganic and organic fertilizer application and management solutions, NUE and crop yield response, case studies from the field, and policy positions. Papers should demonstrate that organic fertilizers alone will not be sufficient for increased yield and profits and that either the balanced application of inorganic and organic fertilizers, or in situations where organic fertilizers are not available, sufficient amounts of inorganic fertilizers alone would be required but without degrading soil or environment.Dr. Jagadish Timsina
