Soil samples were collected from three different habitats at monthly intervals. Order Oribatida was the highest numerically abundant group of acrarines followed by order Mesostigmata. ANOVA indicated significant difference (p<0.05) in population density of oribatid mites among the sites. Five, eight and ten species of oribatid mites were recorded from the waste disposal site at Panga, Denguajha...

Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

BACKGROUND AND AIMS Root soil penetration and path optimization are fundamental for root development in soil. We describe the influence of soil strength on root elongation rate and diameter, response to gravity, and root-structure tortuosity, estimated by average curvature of primary maize roots. METHODS Soils with different densities (1·5, 1·6, 1·7 g cm-3), particle sizes (sandy loam; coarse...

Andrographis paniculata (Burm.f.) Nees is a medicinal herb in the family Acanthaceae. The leaves of the mature plant contain abundant diterpinoids of medicinal properties.The objectives of the present study were to investigate the impacts of compost tea rates on photosynthesis parameters and antioxidant reactions of A. paniculata. The plant was propagated using seed and planting in a polybag. A...

Bacteria transport in soils primarily occurs through soil mesopores and macropores (e.g., biopores and cracks). Field research has demonstrated that biopores and subsurface drains can be hydraulically connected. This research was conducted to investigate the importance of surface connected and disconnected (buried) biopores on Escherichia coli (E. coli) transport when biopores are located near ...

this study was carried out as a factorial experiment with 5 levels of cadmium (cd) (o, 25, 50, 75, and 100 mg/kg), 5 levels of salinity (control, 4, 5, 6, and 7 ds/m), and two soil textures (sandy loam and clay loam). the results showed that the amount of cd in root and shoot of sunflower increased as soil salinity and cd concentration increased. the best concentrations for cd phytoremediation ...

the adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol a on locally available black tea leaves waste and granular activated carbon were investigated. the results obtained indicated that the kinetics of adsorption were ph, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...
