Evaluation of soil fertility status using GPS techniques in Karguaji organic research farm, institute of agricultural sciences, Bundelkhand University Jhansi

The present investigation was under taken with a view to evaluate the fertility status in soils Karguaji organic farm of Institute of Agricultural Sciences, Bundelkhand Unversity, Jhansi district is located at Uttar Pradesh lying between 25? 44’ N latitude and 70? 25’ E longitude with 280 feet mean see level and normal annual rainfall is 550 mm. For evaluation of the soil fertility status of Karguaji organic farm the sample collected from the correct spot with help of global positioning system (GPS), a systematic survey was carried out. A surface (0-15 cm depth) soil sample was collected from the 5 land use pattern/locations. The experimental area was classified in five groups according to their land use pattern S1 -Upper Fallow land, S2- GPB experimental area, S3- SAC experimental area, S4- Barren low land area and S5- AGR (10 soil samples in each land use pattern. It can be concluded the results that most of the soils comes under different land use pattern of in Karguaji organic farm of Utter Pradesh under Bundelkhand region showed low status in available N, P and K and characterized under neutral (6.92) in soil reaction (pH) and less than 1.0 dS m-1 soluble salt content (EC) which comes under safe limit for all soils or no sensitive for suitable crop growth and developments. Most of soil samples observed sufficient level of DTPA-extractable B, Zn and Fe, Mn and Cu, higher level was observed in study area. The organic carbon level exhibited medium. Most of the soils of Karguaji organic farm were characterized by Low and sufficient to High categories macro and micro nutrients in the soils of different land use pattern of Karguaji organic farm. Hence, the soils require attention regarding nutrient management practices and regular monitoring of soil health for better crop production, in sustainable crop productivity.
