Efficacy of a Rock Phosphate Based Soil Implant Formulation of Phosphobacteria in Soybean <i>(Glycine max </i>Merrill)

180-187For improving the effectiveness of low-grade rock phosphate, a granular formulation was developed by immobilizing phosphate solubilizing bacteria (PSB) impregnated rock phosphate in calcium alginate. This process ensured requisite standards of PSB viability in rock phosphate. The formulation was compared with powdered soil and seed formulations for its efficacy in soybean; maximum weight of nodule, dry matter and grain yield, N and P uptake of shoot and grain were recorded with granular preparation. The granular formulation can directly be applied in soil and is environmentally safe

Depositional environment of sediments along the Cuddalore coast of Tamilnadu, India

375-382Surficial sediments of beaches along the Cuddalore, central coast of Tamilnadu from Ponnaiyar estuarine to Thirumulaivasal were studied for their textural parameters namely Mean (Grain size) phi, Standard deviation, Skweness and Kurtosis and mineral percentages. Observed variation of energy conditions are controlled by the fluvial profile in the river channel. Textural analysis of medium sand shows the existence of comparatively high energy condition in the marine environment and low energy conditions in the fluvial zone. Linear Discriminant Function (LDF) analysis of the samples indicates a shallow marine environment origin for most of the samples and very few numbers of samples originated from fluvial environment. Heavy mineral content serves as an index for stratigraphic correlation of unfossilferrous strata. The lowest heavy mineral content indicates progradational activity and low energy wave conditions. These results show that reworked sediments, submerged during the Holocene marine transgression are being deposited on present day beaches by waves, currents and rivers in the study region. </span
