The present study was formulated to study the effect of sugarcane monocropping on soil physical and chemical properties of different textural classess of popular sugarcane growing areas of Visakhapatnam district of Andhra Pradesh. Results revealed that soil physical properties under monocropping were negatively influenced with increasing frequency of ratooning in all the textural classes. However more influence was observed under clay loam soils compared to sandy loams. The data on soil fertility status in different ratoons indicated that the available macro nutrient status and soil organic carbon content was higher in all the surface soils compared to subsurface soils and it was the highest in clay loam soils followed by red loam and sandy loams soils. With in different textural classes, clay loam soils exhibited the highest micronutrient status followed by red loams and sandy loam soils.

“…Soil samples were analyzed for particle size distribution (International Pipette Method) as described by Piper (1966).Water holding capacity (WHC) was calculated from the moisture content of the equilibrated soil (Keen and Raczkowski, 1921). Soil pH and EC were determined at 1:2.5 soil -water ratios using a glass electrode and conductivity bridge, respectively.…”

The aim of this work was to study the effect of nitrogen fixing cover crops on soil organic carbon fractions and nutrient status in apple orchard soils in a chronosequence in north-west Himalaya of Kashmir, India. The experiment include six phases of chronosequence (0, 10, 20, 30, 40 and 50) years under three landscapes. Soil of lower altitudes with no cover crop grown in the orchard floor, the mid altitude soils with berseem (Trifolium alexandrinum) as a cover crop and in the higher altitudes with the alfalfa (Medicago sativa) grown as nitrogen fixing cover crop. There is a perceptible temperature difference across these landscapes. In addition to the apple yield and nutrients content, physical properties and soil organic fractions were investigated. Compared to the sites where no nitrogen fixing cover crops were grown there was 51% and 92% increase in the apple yield over other sites with inclusion of berseem and alfalfa. There was significant increase in yield up to 40 years and declined with advancement of stand age. Higher contents of all soil organic carbon pools were found in the higher altitudes with alfalfa grown as a cover crop in the orchard floor. Lower bulk densities were observed in the sites with cover crops grown in the apple orchard which might have synergistic role on nutrient cycling. There was significant increase of N, K, S, Mg, Fe and Mn and no discernible difference were observed for B, Cu, P and Zn. There was significant increase of the nutrients up to 40 years and afterwards significant drop was observed. Our result suggests that there was significant decrease of the nutrients from vertical soil depth of 0-90 cm.

“…The BD was determined by Edward et al (2001). Further, water holding capacity (WHC) was measured by following the method of Keen and Raczkowski (1921). Solid OC and organic matter (OM) content in the sediments were measured following the method of wet oxidation by Walkley and Black (1934), soil pH was measured based on the using pH electrode (Richards 1954;Grunzweig et al, 2003).…”

The physicochemical characterization of seven marine sediment samples was investigated and collected from different zones along with Thondi coastal sediments along the southeast coast of India. The study found that variation in physical parameters and mud contents were due to differences in sediment source. Results of Station 3 revealed the calculated average values as follows: Bulk density (BD) (1.3 g/cm 3 ), particle size distribution of -sand (50.5%), silt (31.5%), and clay (18%). Further, the water holding capacity (WHC) was observed to be 65.3%. These studies moderately describe the WHC of space or pores of the soil particles. The fine, well sored sediments contain BD, particle size distribution, and water holdinsg capacity. According to the chemical characterization, sediments were categorized into organic carbon (OC) (1.2%) and organic matter (OM) (2.0%) the area for land derived materials from surrounding rocks. Moderate significant linear correlations were observed between OC and TN, indicating the occurrence of these components in a common phase organic matter. Even though, in the correlation of the total phosphate in organic matter, these two elements was negatively correlated, indicating anthropogenic regions of phosphate exportation. The study found three well structured sediments of the bacterial community association and primary productivity.
