Introduction to the Integrated Nutrient Management Strategies and Their Contribution to Yield and Soil Properties

Abstract

Alleviation of poverty and achievement of zero-hunger target and food security are significant challenges faced by agricultural planners worldwide. Improving many agronomic approaches, which have drastic effects on crop growth and yield, is urgently needed to report this aim. Replacement of a part of chemical fertilizers by organic manure through a simple technique of using minimum effective dose of sufficient and balanced quantities of organic and inorganic fertilizers in combination with specific microorganisms, called INM, has a bright solution in this area. Recently, several investigators reported that integrated use of chemical fertilizers with organic manure is becoming a quite promising practice not only for maintaining higher productivity but also for greater stability to crop production. In addition, INM acts as a source of energy, organic carbon, and available nitrogen for the growth of soil microbes and improvement of physical properties of soil, and also have great residual effect on subsequent crops. So, the key component of the INM goal is to reach the eco-friendly practice through the harmonious properties of both sources by making a combination that can be used for decreasing the enormous use of chemical fertilizers and accreting a balance between fertilizer inputs and crop nutrient requirement, maintaining the soil fertility, optimizing the level of yield, maximizing the profitability, and subsequently reducing the environmental pollution. Lastly, INM is a tool that can offer good options and economic choices to supply plants with a sufficient amount of nutrients in need and can also reduce total costs, create favorable soil physiochemical conditions and healthy environment, eliminate the constraints, safeguard the soil nutrient balance, and find safety methods to get rid of agriculture wastes.

Effect of integrated nitrogen management and foliar spray of iron on groundnut yield, quality and economics in arid region

“…Increased availability of nutrients in the root zone coupled with increased metabolic activity at cellular level probably might have increased the uptake and accumulation of these nutrients in the various plant parts. Integrated management of nitrogen plays effective role, in general, on plant vigor contribution, particularly which are related to root development, water and nutrient uptake (Selim, 2020). It appears that organic acids produced from farm yard manure as a source of organic substances may be partly responsible for quick release of nutrients, which resulted into more uptake of nutrients (Mehta et al, 1996).…”

Residual effects of corncob biochar on tropical degraded soil in central Uganda

“…combining half of the sole application of the biochar with half of the sole application of the farmyard compost and NPK (Choudhary et al 2013). IPNS promotes the minimum effective rate of adequate and balanced quantities of applying inorganic and organic resources to results in high soil nutrients availability and crop productivity (Selim 2020). The biochar used was produced from a modified oil barrel having a similar function as the Elsa stove.…”

Fertilization influence on biomass yield and nutrient uptake of sweet corn in potentially hardsetting soil under no tillage

“…Efficient fertilization is one basic nutrient management schemes that holds huge importance in crop production as it serves as a gateway into increasing crop productivity and nutrient use efficiency (Yousaf et al 2017;Seleiman et al 2021). Furthermore, the addition of fertilizer determines the amount of nutrients that plants could access, as native nutrients present in the soil would not last for long-term crop production (Selim 2020). Addition of inorganic fertilizer, which is chemically synthesized and organic fertilizer in the form of livestock manure, green manure, crop residues and composts, has long been debated as to which promotes and preserves soil health in the long run (Seleiman et al 2012(Seleiman et al , 2020Geng et al 2019).…”
