Abstract


The evaluation of the fertility status of an agricultural field is an essential parameter in terms of sustainable productivity of crops. Macro and micro nutrient elements govern the fertility of soils and control the growth, development and yield of crops. This Study was conducted to assess the soil fertility of some selected land classes of Tripura. For this purpose 50 surface soil samples were collected from all the districts of Tripura covering different land classes. The data shows that these soils were acidic in nature, medium in available Nitrogen content, low in available phosphorous and medium in available potassium. The concentrations of available Zn in all the soil samples analyzed were low which could be as a result of the strongly acidic nature of the soils in the study area. We therefore recommend that agricultural lime be applied on the soil so as to raise the soil pH to required level of 5.5 – 7.8 for crop productivity
