Kolhapur, MS, INDIA Available online at: www.isca.in Received 6th April 2013, revised 17th April 2013, accepted 6th May 2013Abstract The most important variables in the soil are the plant nutrients. Laboratory study was conducted to evaluate the soil fertility status of different soil samples of Rice Field in Gadhinglaj and Ajara Tahsil. Aimed at assessing these variables .The soil samples were collected in Nov 2012 from Rice field in Gadhinglaj and Ajara Tahsil. Parameters like pH ,TDS, E.C., Water holding capacity, Nitrate nitrogen, Ammonium nitrogen, Potassium, Sulphur, Calcium, Magnesium, Chloride and Phosphorous was analyzed. It was found that soil sample S has lower amount of Magnesium and Soil samples S and Srequired more secondary nutrients. Keywords: Soil parameter, soil quality, rice field and nutrients.Introduction Soil fertility is simply defined as the ability of the soil to supply nutrients for plant growth. The soil is a store house of plant nutrients. The nutrients are stored in many foams, some very available to plants while some unavailable plant nutrients are essential elements needed for plant growth. Plants adsorbed 90 different elements some of these elements are needed for plant growth and some are not needed by plants. Lack of the element stops a plant from completing growth or production. A shortage of the elements can be corrected only by supplying that elament, Nitrogen, Phosphorous and Potassium are primary nutrients which are most likely to be added to soil by fertilization. The other elements Boron, Copper, Chlorine, Zinc, Molybdenum, Iron and Manganese are labeled as micronutrients elements or trace elements. Because they are used by plants in such small quantity. Plant growth will be affected without enough of these trace elements. Material and MethodsSoil Samples 1, 2, 3 and 4 were collected from Honyali, Mahagaon, Uttur and Badyachiwadi respectively. The micronutrients were determined in the laboratory of Department of AGPM Devachand College, Arjunnager, Kagal Tahsil (M.S). Results and DiscussionpH: In the present study pH was observed in the ranges of 6.9 to 8.0 .the soil sample S, S, S are alkaline samples and S is acidic samples. E.C: In the present study conductivity values ranges from 0.59 mmho to 0.86 mmho. Conductivity of samples S is less as compared to sample S, S and S. Available Nitrate Nitrogen: Available nitrate nitrogen in the soil samples ranges from 215.04 kg/hectare to 257.6 kg/hectare. The soil sample S1 has high nitrate nitrogen as compared to sample S2, S and S. Ammonium Nitrate Nitrogen: Available ammonium nitrate in the soil sample ranges from 399.8 kg/hectare to 270.54 kg/hectare. The soil sample S has high ammonium nitrate as compared to sample S, S and S. Phosphorous: Phosphorous content in the soil sample ranges between 22.5 kg/hectare to 50 kg/hectare. Sample S have more Phosphorous content as compared to sample S, S and S. All samples are within normal range. Potassium: Potassium regulates many metabolic processes required for growth, food and seed development. Many vegetables and fruits crop are high in Potassium which is vital for animal and human nutrition. Potassium content in the soil sample ranges between 164.3kg/ha to 303.5 kg/ha. The soil sample S has more Potassium content as compared to sample S, S and S. All samples values are within the normal range. Magnesium: Magnesium available to plants as the ions Mg+2. Magnesium content in the soil sample ranges from 2% to 7 %. Sample S contain less amount of Magnesium.

International Science Congress Association 25 Chloride: In present study Chloride ranges from 25 % to 50 %. Soil sample S and S have low chloride content than S2 and S. Calcium: Calcium ranges from 10 ml/100gm to 25 ml/100gm. Soil sample S have high Calcium content as compared to sample S, S and S. Sulphur: Sulphur content value ranges from 5.8 kg/hectare to 15.68 kg/hectare. Sample S have low Sulphur content as compared to sample S, S and S4 .Deficiency causes plant stems are stiff, thin and woody and growth rate is retarded and maturity is delayed. Total Dissolved Solids: TDS values for soil samples ranges from 0.38 to 0.66 .Soil sample S has lowest TDS as compared to S,S and S . Water Holding Capacity: Different types of soil have different capacities to hold water. Sandy soil has lower capacity as compared to Clay soil. In present study Water Holding Capacity value ranges from 34.2 to 0.52. Soil sample S has highest Water Holding Capacity as compared to S, S and S. ConclusionIt is concluded from the data soil sample S2 required Ammonium Phosphate and Secondary nutrients, Sample S and Having good quality of Nitrogen, Phosphorous and Potassium nutrients. Conducting capacity of all samples is found to be medium. Magnesium content in soil sample S1 is in lower amount so fertilizer containing Magnesium is added for proper growth and development of the crops. All soil samples are within the permissible limit.
