Assessment For The Fertility And Physico- Chemical Properties Of The Soil Of Pfiichama And Phesama Village Under Kohima District, Nagaland

Abstract

      Macro and micronutrients content were investigated through chemical process to check the fertility status of soils of Pfiichama and Phesama village of Kohima district of Nagaland. p^H values of these two villages were in between 4.8 to 6.7 which indicates that these soils are strongly to moderately acidic in nature. EC values were in the range of 0.11 – 0.14 which implies that the salinity effect is negligible. Nitrogen content was in the very low to medium range, Potassium, chloride and organic carbon content were in the high range where as Phosphorus was in low to medium range and sulphur contents were in the low range. Iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu) and Boron (B) contents were in sufficient range.  Water holding capacity and % of moisture were also determined. Assessment of the soil's fertility and nutrient content was done to provide a measure of the nutrients that are present or contribute to a particular soil.  On the basis of physicochemical analysis and Nutrient index value study recommends the use of limited and selected amount of fertilizers to improve the fertility status of the selected locations to enhance the production and quality of crop.
