Ecosystems have been affected by series of activities that occurred on lands. The effects land use change the physical and chemical properties soil in Oba Hill Forest Reserve studied using standard instrumentation techniques. Results obtained showed texture soils ranged from loam to sandy while pH four types 4.92 (acidic) 7.80 (alkaline).The bulk densities are natural forest (1.01 g/m3), teak p...

Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...

soil and land information is vital for land use planning and infrastructure development. maps of soils landscapes are powerful tools to guide sustainable planning and natural resource management. fuzzy set theory has been widely used in soil science for soil classification and mapping, land evaluation, fuzzy soil geostatistics, soil quality indices. in fuzzy logic-based approaches, soil spatial...

We examined the consequences of soil erosion processes following deforestation and long-term pasture establishment for chemical physical properties Fe isotope compositions within two distinct areas in Eastern Central parts Amazonia (near Rio Capim, Para, Brazil Lake Balbina/Rio Uatuma, Amazonas, Brazil). For each area studied, soils selected under forest cover or after recent slash-and-burn pra...

An experiment was carried out to assess the effect of four nitrogen levels viz. T1 (full doze of urea i.e. 215 kg urea ha-1 at 15 DAT), T2 (full doze of urea at two equal splits, ½ at 15 DAT + ½ at 30 DAT), T3 (full doze of urea at two equal splits, ½ at 15 DAT + ½ at 55 DAT) and T4 (full doze of urea at three equal splits, 1/3 at 15 DAT + 1/3 at 30 DAT + 1/3 at 55 DAT) on morpho-physiological ...
