The Amazonian rainforest is critical to our shared human future. Therefore, we need to understand the structure and function of their forests and soils are a critical part of that investigation. Towards that end, soil samples were taken in eight different forests, both non-flooded (terra firme-low forests, terra firme-high forests, white sand-varillal forests, white sand-chamizal forests and palm forests) and flooded by...

Climate change is unequivocal and its threat on rain fed agriculture in the tropics is a fact. Changes in temperature, sparse and irregular rainfall, runoff patterns entail droughts extremes, excess evapotranspiration and loss of soil moisture. These items drive soil degradation, crop production, distribution, and supply of food, and subsequently food riot and social stability. Therefore, it urges to develop and improve... Read more.

The study aimed at assessing potential influence of anthropogenic activities on the level of selected toxic heavy metals in soil in Tsumeb Township, Namibia. This was with a view of evaluating possible implications on human health and across the food chain. Soil samples were randomly collected from stratified areas and taken to the laboratory for pre-treatment and analysis. Soil metallic contents were extracted using... Read more.

Winter cover crops are cultivated during cold fallow season in temperate countries for green manure and animal feed. Literature on incorporated biomass composition in relation to soil respiration like CH4-C and CO2-C is not available. Therefore, soil respiration as affected by variable biomass composition was determined from paddy soil. Soil respiration rate (1280-1341 kg ha-1) was significant when 197 and 204 day-old...

Waterleaf (Talinum triangulare), like many other leafy vegetable is cultivated in home gardens to improve nutritional quality for the family and may provide additional income for female farmers. However, the role of Talinum cultivation is often counteracted by declining soil fertility. In recent years, biochar (pyrolysed biomass) has gained importance as a soil amendment tool. However, not much attention has been... Read more.

Understanding of phosphorus (P) retention and release mechanisms provides crucial information for the effective management of phosphorus to enhance crop production and sustain soil. In acidic soil, available phosphorus is fixed by aluminum and iron. To overcome this problem, soils are limed to fix aluminum and iron. But this practice is not economical for small scale farmers and also it is not environmentally friendly.... Read more.

Since composts are soil like amendments made from plant and animal remains, they are more important than inorganic fertilizer because they consist of relatively stable decomposed materials resulting from accelerated biological degradation of organic matter. However, little attention has been paid on the use of compost as bio-fertilizers to improve soil structure, fertility and consequently ... Read more.
