Micronutrient Fertilizers - a review

Globally, due to intensive cultivation, there is a deficiency of micronutrients in the soil leading to poor yield. Some of the key micro nutrients boron, chlorine, copper, iron, manganese, molybdenum and zinc is deplete with frequent repetition of crops. When samples of Indian soils are analysed, 50% of soil have nutrient deficiency. Indian soils high with Potassium deficiency are found in 25% of soil samples analysed and high Sulphur deficiency is found in 49% of soil samples analysed. It is also found that soils 33% are deficient in Zinc, 12% in Boron and in Iron. The country should also learn that bringing hybrid seeds or genetically modified seeds will not yield results if planted in non fertile soil. We are seeing an increase in fertilizer usage but diminishing yields due to lack of m
