Soil structural stability is a vital aspect of soil quality and functions, maintaining sustainable land management. The objective this study was to compare the contribution four long-term land-use systems (crop, bush, grass, forest) coupled with anionic polyacrylamide (PAM = 0, 25, 200 mg L?1) application on soils in three watersheds Ethiopia varying elevation. Effect treatments indices were as...

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...

Charcoal is one of the important energy sources in the developing countries. Additionally, it is effective not only in carbon fixation and inactivation in the atmosphere but also in environmental conservation when used as an agent such a soil conditioner or growth accelerator of plants. However the utilization of charcoal in forestry sector, especially industrial plantation, has not been introd...

Two field experiments, organized in randomized complete block design, were conducted in 2005 and 2006 farming seasons at Nyankpala in the Northern Region of Ghana to investigate the effects of planting depth (1, 2, 4, 6 and 8 cm) and land preparation methods (flat field, mounding and ridging) on crop establishment (percentage number of established plants) and grain yield of soybean (Glycine max...

Factorial combinations of soil compaction and organic matter removal were replicated at the Long Term Site Productivity study in the Croatan National Forest, near New Bern, North Carolina, USA. Ten years after planting, 18 preselected loblolly pine (Pinus taeda L.) trees were destructively harvested to quantify treatment effects on total aboveand below-ground tree biomass and to detect any chan...
