Keywords: physico-chemical properties, macronutrients, micronutrients, inceptisols Introduction The extreme southern part of Marathwada is occupied with Osmanabad and Latur district. Geographically, Osmanabad district is located between 18o 28’ to 19o 28’ North altitude and 76o 25’ to 77o 25’ East latitude. The geographical area of Osmanabad district is 7512.40 sq.km. The climate of the area is hot and dry having average annual rainfall 767.5mm. These soils has light medium and heavy texture with undulating topography and varying in soil depth. This district comprises 8 tahsils, out of these, Washi tahasil is selected for study. In this tahsil, there is cultivation of different cereals, pulses, oilseed and horticultural crops. Average annual rainfall was 715.6 mm The physico-chemical properties like pH, EC, calcium carbonate and organic carbon play important role in relation to availability of nutrients in soils and thereby on crop growth and production. The organic carbon is the store house of all plant nutrients. It provides good aeration, increases microbial activity, water holding capacity; maintain the soil pH, CO2 level and calcium carbonate content in the soils. (Malewar, 1995) [22]. Every primary and secondary nutrient play important role in soil to maintain the soil fertility and agricultural production. The physico-chemical characteristics, available macro and micronutrient status in the soil profile helps in determining the soil potential to supply nutrients for crop growth. Macronutrients (N, P and K) and micronutrients (Zn, Fe, Mn, Cu and B) are important soil elements that control soil fertility. Soil fertility is one of the important factor controlling yields of the crops. The present investigations were undertaken in Washi Tahsil of Osmanabad district (M.H.) to know nutrient availability of the soils of Washi Tahsil to improve agricultural production by supplying required quantities of nutrients through different fertilizers. Correspondence Priyanka B Patil Materials and Methods Department of Soil Science and Out of 54 villages of washi tahsil 30 villages were selected for this study. The villages were Agricultural Chemistry, College selected randomly in such way that it should cover whole area of the tahsil. Sixty soil samples of Agriculture, Latur, were collected from Inceptisols of 30 villages of Washi tahsil. These soil samples were dried Maharashtra, India and processed. The samples were analysed for particle density and bulk density by Pycnometer ~ 1240 ~ International Journal of Chemical Studies and clod coating methods, respectively (Das and Agrawal, in Nagpur district of Maharashtra in different horizons. 1997). pH and Electrical conductivity (E.C.) in 1:2.5 soil Particle density of soils from Inceptisol order ranged from [5] -3 -3 water suspension (Jackson, 1978) . Organic carbon 2.03 to 2.96 Mg m , with mean value 2.40 Mg m . The estimated by modified method of Walkely and Black (Piper, particle density is higher, it might be due to large amount of 1966). The free calcium carbonate was determined by rapid heavy minerals such as magnetite, limonite and hematite are titration method as outlined by Piper (1966) [19]. present in the soil. With increase in organic matter of the soil, Available nitrogen was analyzed by using alkaline potassium the particle density decreases. Singh and Mishra (2012) permanganate method (Subbiah and Asija, 1956). Available reported that the particle density in Chairaigaon block of phosphorus was determined by using 0.5 M sodium Varanasi district in U. P. soils varied from 2.0 to 2.6 g cm-3, bicarbonate as an extractant by Olsen’s method on respectively. Whereas porosity was ranged from 20.00 to spectrophotometer (Jackson, 1978) [5]. Available potassium 56.00 per cent with mean value 37.66 per cent. was treated with normal ammonium acetate and potassium was determined from the extract by using flame photometer Chemical Properties: The data in table 2 revealed that the (Jackson, 1978) [5]. Exchangeable calcium and magnesium pH of these soils was varied from 6.3 to 8.5 with an average was analyzed by ammonium extracts of soils by titration with value 7.53. The data indicated that, the Inceptisol soils of EDTA (Jackson, 1978) [5]. Available sulphur was determined Washi tahsil were neutral to alkaline in reaction. These results by using 1:5 soil and extractant, 0.15 per cent CaCl2 solution in accordance with Raut and Mali (2003). The electrical on spectrophotometer (Willams and Steinberg, 1969). conductivity of these soils was ranged from 0.10 to 0.42 dSm- Micronutrients were estimated as per the procedure described 1 with an average mean of 0.19 dSm-1. The low EC in these by Lindsay and Norvell (1978) [8]. For this 10 g finely sieved soils might be due to proper management of soil and thereby soil (0.5 mm) was taken in 20 ml of 0.005 M DTPA solution leaching of salts take place from surface to subsurface. These (Diethylene Triamine Penta Acetic Acid) containing 0.1 M results are confirmatory with results reported by Patil and triethanol amine and 0.01 M calcium chloride, adjusted to pH Kharche (2000). The data on organic carbon and organic 7.3 with HCl for two hours and then filtered and filtrate was matter content presented in table 2 revealed that the organic subjected to measurement on Atomic Absorption carbon content ranged from 0.50 to 10.40 g kg-1with the mean Spectrophotometer (AAS-200), at different wavelengths for value 4.81g kg-1 and organic matter ranged from 0.86 to 17.92 Fe, Zn, Mn and Cu. Available boron was determined from g kg-1 with mean value of 8.29 g kg-1. Waikar et al. (2004) soil samples by using Azomethine-H on spectrophotometer at reported that the organic carbon in the soils of Marathwada 420 nm wavelength (Gupta, 1979) [4]. region were ranges from 7.0 to 25.0 g kg -1.The calcium carbonate content in these soils were ranged from 4.00 to Results and Discussion 168.00 g kg-1with a mean of 46.52 g kg-1. The low to medium Physical Characteristics: The data present in Table 1 CaCO3 content in soils might be due to fact that presence of revealed that the average bulk density under Inceptisol order CaCO3 in powdery form and hyper thermic temperature -3 - renges from 1.13 to 1.86 g cm with mean value of 1.50 g cm regime of Washi tahsil. The CaCO3 content of the pedons 3. These results are in agreement with results reported by increased with depth, which explains downward movement of Leelavati et al. (2009). Jagdish Prasad (2010) observed that calcium and decomposition of CaCO3. These results are in the bulk density of soil was ranged from 1.39 to 1.76 Mg m-3 confirmatory with the results reported Meena et al. (2006) [13].
