Soil amendments play an important role in management of pesticide residues. In this study, incubation experiment was conducted using the surface (0 15 cm) sample of a mollisol supplied with different soil amendments (farmyard manure, cow-dung slurry, pyrite and gypsum) to investigate the effect of amendments on the dissipation of lindane in mollisols. Dissipation of lindane in soil was studied ...

The effect of sole application of inorganic fertilizers (NPK) (N:P:K:: 30:26:25 kg ha ) and combined application of farmyard manure (FYM) @ 4 Mg ha 1 and inorganic fertilizers (NPK + FYM) vis-a-vis nonapplication of fertilizers and manures (control) on changes in soil physical properties and plant growth characteristics of soybean (cv. JS 335) was studied in a deep Vertisol at the Indian Instit...

Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...

ltesults of inoculation experiments with an efficient strain of Rhizobium (eB 756) indicated that indigenous strains occupied most of the nodules of groundnut, grown in high Rhizobiullt gl"Oundnul populatell soils. These could he overcome hy using high rate of inoculation containiug trace clements, molyhdenum and horon, at 1.6 ppm and 4 ppm, respectively, wilh higher rates of phosphate applicat...

The impact of three different soil DNA extraction methods on bacterial diversity was evaluated using PCR-based 16S ribosomal DNA analysis. DNA extracted directly from three soils showing contrasting physicochemical properties was subjected to amplified ribosomal DNA restriction analysis and ribosomal intergenic spacer analysis (RISA). The obtained RISA patterns revealed clearly that both the ph...

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha. There were 17 tr...

An experiment was carried out on loamy sand soil to evaluate the effect of organic manures (farmyard manure, vermicompost, poultry manure, neem cake and castor cake) on soil and quality parameters of cowpea during summer season of 2014. Nine treatments were tried out in randomized block design with four replications. Recommended Dose Fertilizer (RDF) i.e. 2040-0 NPK kg ha-1 recorded significant...
