Application of organic amendments is known to improve soil fertility, soil physical properties, one of which is water holding capacity. Incorporating manures into the top soil layer makes the layer fertile and hold more water, thus making corn roots thrive in this layer. Our results showed a significant increase in sweet corn root’s growth in the top 15 cm under organic amendments compared to t...

Coastal sandy soil is characterised by low fertility and poor physical properties. Distillery effluent, a liquid waste from the distillery industry contains large quantities of soluble organic matter and plant nutrients. It does not contain any toxic elements / compounds. In order to improve the physical properties and fertility of the coastal soil by utilising the distillery effluent, field ex...
The long-term effects of green cane harvesting with trash retention, compared with burning, on soil fertility were evaluated using data from the long-term trash management trial at Mount Edgecombe (BT 1). Total and potentially mineralisable soil N were greater under green cane harvesting than burning in the surface 0-10cm layer of soil. As expected, fertiliser applications induced increases in ...
Deforestation leads to the deterioration of soil fertility which occurs rapidly under tropical climates. Forest rehabilitation is one of the approaches to restore soil fertility and increase the productivity of degraded areas. The objective of this study was to evaluate and compare soil biological properties under enrichment planting and secondary forests at Tapah Hill Forest Reserve, Perak aft...
The use of excess conventional Phosphorus (P) fertilizers to improve agricultural productivity, in order to meet constantly increasing global food demand, potentially causes surface and ground water pollution, waterway eutrophication, soil fertility depletion, and accumulation of toxic elements such as high concentration of selenium (Se), arsenic (As) in the soil. Quite a number of soil microor...
The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...
AIM Geographic, climatic, and soil factors are major drivers of plant beta diversity, but their importance for dryland plant communities is poorly known. This study aims to: i) characterize patterns of beta diversity in global drylands, ii) detect common environmental drivers of beta diversity, and iii) test for thresholds in environmental conditions driving potential shifts in plant species co...
Cottonseed, oil, and protein, as the by-products of cotton production, have the potential to provide commodities to meet the increasing demand of renewable bio-fuels and ruminant feed. An increase in crop yield per unit area requires high-yielding cultivar management with an economic nitrogen (N) rate, an optimal N application schedule, high-yielding plant populations and strong seedlings. Whet...
Soil is the basic requirement for agriculture crop production and simultaneously microbial activity important to improve soil health healthy growth because communities play an role in building a complex link between plants soil. Microbiomes from plants, extreme environments are naturally gifted with amazing capabilities which significant roles maintenance of global nutrient balance ecosystem fu...
