That is a good question. The effect of balanced fertilization on soil organic carbon (SOC) depends on many factors, such as the type and amount of fertilizer, the soil properties, the crop rotation, and the environmental conditions. Balanced fertilization usually means applying organic and inorganic fertilizers in appropriate proportions to meet the nutrient requirements of crops and maintain soil fertility. Balanced fertilization can increase SOC by enhancing crop biomass production, soil microbial activity, aggregate stability, and organo-mineral interactions12.
However, short-term imbalanced fertilization can have negative impacts on SOC and soil quality. Imbalanced fertilization can mean either over-application or under-application of certain nutrients, especially nitrogen (N). Over-application of N can accelerate SOC decomposition, increase greenhouse gas emissions, leach nitrate into groundwater, and cause eutrophication of surface water34. Under-application of N can limit crop growth, reduce residue inputs, and decrease SOC sequestration5. Therefore, short-term imbalanced fertilization can potentially nullify the beneficial effect of balanced fertilization on SOC, depending on the severity and duration of the imbalance. It is important to monitor soil nutrient status and adjust fertilizer application accordingly to optimize SOC management and environmental protection.
The use of right ratio of nutrients as per soil or crop requirement is known as "balanced fertilization.” Balanced fertilization leads to building up soil health, while imbalanced fertilization leads to soil mining and its sickness. “Imbalanced fertilization results in low fertilizer efficiency and has negative environmental effects, such as soil acidification, soil compaction and water eutrophication. Excess fertilizer alters the soil by creating too high of a salt concentration, and this can hurt beneficial soil microorganisms can burn or desiccate roots, ultimately killing the plant. Balanced Fertilization Can Sustaining Crop Productivity.
The accumulation of plant nutrition is related to maintaining an adequate pH or aciidity to promote nutrieent availabilty. In addition the water relationship is related to the ability of the soil medium to maintain the stocks of soil organic to favor the aeration and water percolation and retention so soil organic matter which has not been given a principal place in chemical agricuture is the key to improving all agriculture.
The effect of ammoniated fertilizer the most used around the globe is to stimulate an acidification of the soil medium which can occur quite drastically in low organic soils and the dramatic effect can be the soil aciid infertility complex when the toxicity of aluminum manganese and iron lead to a very poor environment of plant growth and development.
In an alkaline soil environment the effects of ammonium soil acidification will be favorable at first because the more neutral condition in the short term will lead to greater nutrient availability.
The concept of nutrition is that nutrients are limiting factors and lowest essential nutrient gives the status as limiting factor. So the key is making all the nutrients optimized and not concentrating on solely one but taking the most limiting as a starting priority.
The ammoniated nitrogen focus only focuses on nitrogen but the others are left out. In an organic approach we can in reality increase N and all the rest by optimizing soil organic matter. Not only increasing the yield by the quality of the crops and animals produced.
The sole focus on nitrogen is a critical problem in improving the stability yield and quality of our food stuffs. We need a more holistic nutrition based approach to improve our food and nutrition the focus on soil organic matter and balanced nutrition is the way to go.
