In general the Physico -chemical properties, macronutrients were correlated significantly and negatively with pH and positively Fertilizer with organic carbon of the soil. The values of the organic carbon, Alkaline recommendations KMnO4 extractable N, Olsen’s P and neutral normal Ammonium Acetate and Udham Singh extractable K in the Udham Singh Nagar district ranged between 0.13-1.64 per Nagar cent, 125.44-338.68 kg N ha-1, 7.34 -76.70 kg P O ha-1 and 66.08-271.04 kg K O 2 5 2 Article Info ha-1, respectively. From the above findings it may be concluded that the soils of Accepted: Udham Singh Nagar district are low in nitrogen, sufficient in phosphorus & in 04 May 2017 potassium, Except Sitarganj, Jaspur and Bazpur samples were low in potassium, Available Online: sufficient in sulphur except Rudrapur. These findings from present study can 10 June 2017 successfully be utilized for the larger parts of Tarai region of Uttarakhand as effective guide for efficient and balanced fertilizer recommendations. Introduction Soil plays a major role in determining the determined that most plant nutrients are sustainable productivity of an agro- optimally available to plants within 6.5–7.5 ecosystem. The sustainable productivity of a pH range, also this range of pH is generally soil mainly depends upon its ability to supply very compatible to plant root growth. essential nutrients to the growing plants. The Nitrogen (N), Potassium (K), and Sulphur (S) deficiency of micronutrients has become are major plant nutrients that appear to be less major constraint to productivity, stability and affected directly owing to variation in soil pH sustainability of soils. The availability of than many others, but still are to some extent. some plant nutrients is greatly affected by soil pH. The ideal soil pH is close to neutral, and Nitrogen is primarily responsible for neutral soils are considered to fall within a vegetative growth. Nitrogen assimilation into range from a slightly acidic pH of 6.5 to amino acids is the building block for protein slightly alkaline pH of 7.5. It has been in the plant. It is a component of chlorophyll 235 Int.J.Curr.Microbiol.App.Sci (2017) 6(6): 234-240 and is required for several enzyme reactions. roller, passed through a 2 mm sieve and Phosphorus is a major component in plant stored in a labeled polythene bags.Soil texture DNA and RNA. Phosphorus is also critical in of soil was determined with the help of root development, crop maturity and seed bouyoucous hydrometer method (Moodie et production. The role of potassium in the plant al., 1959). The pH of the soil was determined is indirect, meaning that it does not make up in 1:2 (soil:water) ratio after half an hour of any plant part. Potassium is required for the equilibrium using glass electrode on a digital activation of over 80 enzymes throughout the pH meter (Jackson, 1967). Electrical plant. It's important for a plant's ability to conductivity of the soil sample was measured withstand extreme cold and hot temperatures, in 1:2 (soil: water suspension) at 25ºC using drought and pests. Potassium increases water conductivity meter (Bower and Wilcox, use efficiency and transforms sugars to starch 1965). Organic carbon content in the soil was in the grain-filling process. S is essential in determined by modified Walkley and Black forming plant proteins because it is a method (1934) as described by Jackson constituent of certain amino acids. It is (1967). Available nitrogen was estimated by actively involved in metabolism of the B alkaline KMnO4 method (Subbiah and Asija, vitamins biotin and thiamine and co-enzyme 1956). Available phosphorus was extracted by A. S aids in seed production, chlorophyll Olsen’s method (Olsen et al., 1954) using formation, nodule formation in legumes, and 0.5M NaHCO3 (pH 8.5) and developing the stabilizing protein structure. blue colour with ascorbic acid method of Murphy and Riley (1962). The intensity of In Uttarakhand the farmers are not aware how blue colour was recorded on pH, EC and soil texture affects the availability spectrophotometer at 882 nm. Potassium was of major nutrients in soil, which surely affects determined by using neutral ammonium the crop growth and production of the crops. acetate as extractant (Hanway and Hiedal, So keeping this fact in mind the present study 1952). Potassium concentrations in the “Availability of Macronutrients and their extracts were read by using flame photometer. Relationship with some Soil Properties in Final values in soil were reported in kg ha-1. Molisols of Udham Singh Nagar District of The 0.15% calcium chloride extractable Uttarakhand” is done. sulphur was determined by the method suggested by Williams and Steinbergs (1959). Materials and Methods Most of the blocks were high in pH value; this might be due to presence of calcium The present study was conducted on the soils carbonate and soluble salts and exchangeable of different villages of district Udham Singh sodium on exchange complex which gave Nagar which is situated in Uttarakhand state. soils higher pH. The observed value of soil The soil and plant sample (Wheat) were taken pH was quite comparable to that observed from each block of district, 6 soil samples earlier by Kumar (1988) for soils of Siwaya were collected from a single block.

The higher value of P2O5 in some blocks of Udham Singh Nagar district might be due to Results and Discussion good organic carbon, about neutral soil pH and less fixation of P. Similar reason was also Nitrogen suggested by Shah (1999) in some soils of western U.P. Available nitrogen extracted by alkaline- KMnO4 method of the experimental district Potassium Udham Singh Nagar showed in table 1, varied from 125.44-338.68 kg N ha-1 with mean Available potassium extracted by neutral value of 187.26 kg N ha-1.
