Evaluation of Soil Fertility Status from Milkipur Village, Arajiline Block, Varanasi, District, Uttar Pradesh, in Relation toSoil Characteristics

摘要

Soil fertility evaluation of an area or region is an important aspect in context of sustainable agriculture production. The macro nutrients govern the fertility of soils and control the growth and yields of crops. The area which was selected for the study is Milkipur. The aim of this study was to evaluate soil fertility status from Milkipur village, Varanasi district, U.P. 38 surface soil (0-15 cm) samples were analyzed for various soil fertility parameters like pH, EC, Organic matter, available N, Pand K. Bulk density, Particle density and Porosity by standard procedure. The pH ranged from 6.5 to 8.0 reflecting nearly neutral to slightly alkaline nature of soils. EC ranges between 0.07 to 0.60dSm'. Organic carbon ranges from 0.33 to 0.75%.42% samples showing low and 57.89% samples showing medium organic carbon status respectively. 100% samples are in low status in available N and most of the soil samples have medium status in P and K, 14.2% soil samples are high in Phosphorous improper agriculture practices, intensive farming, monoculture type of cropping pattern and over irrigation are responsible for degradation of soil fertility from the area. Bulk density ranges from 1.35 to 1.42Mg m ', Particle density ranges from 2.24 to 2.39 Mg m"3 and Porosity ranges from 36.1 to 54.0%. To overcome the adverse effect, complementary use of biofertilizers, organic manures in suitable combination of chemical fertilizers were suggested. Awareness camps, rallies, and training program can be arranged for farmers regarding the benefits of balanced use of chemical fertilizers and use of organic agriculture in crop production in improving soil fertility and nutrition status.
