Effects of Vermicomposts on Plant Growth
The use of organic matter such as animal manures, human waste, food wastes, yard wastes, sewage sludges and composts has long been recognized in agriculture as beneficial for plant growth and yield and the maintenance of soil fertility. The new approaches to the use of organic amendments in farming have proven to be effective means of improving soil structure, enhancing soil fertility and incre...
متن کاملManures behave similar to superphosphate in phosphorus accumulation in long-term field soils
Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...
متن کاملA critical review of the bioavailability and impacts of heavy metals in municipal solid waste composts compared to sewage sludge.
The content, behaviour and significance of heavy metals in composted waste materials is important from two potentially conflicting aspects of environmental legislation in terms of: (a) defining end-of-waste criteria and increasing recycling of composted residuals on land and (b) protecting soil quality by preventing contamination. This review examines the effects of heavy metals in compost and ...
متن کاملImpact of soil health management practices on soilborne pathogens, nematodes and root diseases of vegetable crops
Various cultural practices, including the use of cover and rotational crops, composts, tillage systems, and others have been promoted as management options for enhancing soil quality and health. All cultural practices are known to directly or indirectly affect populations of soilborne pathogens and the severity of their resultant root diseases. Soil biology is a major component and contributes ...
متن کاملOrganic Manures , Composts and Artificial Fertilizers
Mineral Fertilizers. It is considered to be the hall-mark of the good agriculturist that he aims not only to produce maximum crops, but to maintain the fertility of his soil unimpaired for the benefit of posterity. Both these ends were achieved in former times by the use of animal manures, by fallowing at regular intervals, and at a later date by the practice of crop rotation in conjunction wit...
