Controls of Soil Spatial Variability in a Dry Tropical Forest
We examined the roles of lithology, topography, vegetation and fire in generating local-scale (<1 km2) soil spatial variability in a seasonally dry tropical forest (SDTF) in southern India. For this, we mapped soil (available nutrients, Al, total C, pH, moisture and texture in the top 10 cm), rock outcrops, topography, all native woody plants ≥1 cm diameter at breast height (DBH), and spatial v...
متن کاملProspect and importance of green mulching on the soil status of tropical tasar plantation fields in India
The soils of tropical tasar plantation fields in general are sloppy and are primarily deficient of nutrition due to top soil erosion and constant leaf productivity exploitation to rear tasar silk insect, Antheraea mylitta Drury. The rainfed field of Terminalia tomentosa (W&A) plantation has been evaluated for soil fortification with green mulching through legumes, Sun hemp (Crotalaria juncea), ...
متن کاملNumerical Simulation of Soil Evaporation with Sand Mulching and Inclusion
A model of unsaturated soil-water movement using a prediction model of basic physical soil properties for calculating correlation functions was developed using VADOSE/W. The reliability of the model was assessed by comparing the results with those of a soil-column test. Coefficients of determination, R2, between the simulated and the measured daily evaporation for sand-mulch thicknesses of 0 (c...
متن کاملTemperature Dependent Decline in Soil Methane Oxidizing Bacterial Population in Tropical Dry Deciduous Forest Ecosystems
Culturable methanotrophic bacteria (CMB) were studied in the soils of forest and savanna of tropical dry deciduous forest ecosystems employing most probable number (MPN) technique. The spatiotemporal study was conducted at the six sites differing in the soil physicochemical properties and vegetational cover. CMB population was high in the moist sites compared to the dry sites and in sub soil be...
متن کاملA non-native invasive grass increases soil carbon flux in a Hawaiian tropical dry forest
Non-native plants are invading terrestrial ecosystems across the globe, yet little is known about how invasions impact carbon (C) cycling or how these impacts will be influenced by climate change. We quantified the effect of a non-native C4 grass invasion on soil C pools and fluxes in a Hawaiian tropical dry forest over 2 years in which annual precipitation was average (Year 1) and 60% higher t...
