While Integrated Nutrient Management (INM or IPNM) involves combined application of organic and inorganic sources of plant nutrients, how it differs from Integrated Soil Fertility Management as practiced in sub-Saharan Africa. What are the research priorities in the two nutrient management strategies?
Both almost have the same meaning. The concept center on the combined use of chemical fertilizers and locally available materials (such as lime and phosphate rock) and organic matter (crop residues, compost and green manure). However Integrated Soil Fertility Management adopted mainly in SS Africa focus on the improvement in soil fertility over the time and rehabilitation of degraded soil, the main problem there. In other words we can consider Integrated Nutrient Management is the broader concept and Integrated Soil Fertility Management derived from it.
INM includes management of essential nutrient using differrent chemical fertilizers using different methods of fertilizer application.while Integrated soil fertility management includes application chemical and organic fertilizers .controling and managening soils and preventing the degradation of soil ....etc
