Previous studies with paper mill sludge have shown that this by product of paper manufacturing decreases cotton yields when it is applied either soil incorporated or as vertical mulch.
Poultry litter manure is a renewable fertilizer resource that contains all the plant nutrients required for plant growth and reproduction.
Eutrophication. Pfisteria. Hypoxia.These environmental problems have plagued the Chesapeake Bay area in recent years. According to reports, the problems may be related to the excessive amounts of nutrients – especially phosphorus – that enter the watershed from areas of intensive poultry production surrounding the bay.
Previous research with sugarcane production in Louisianahas shown that semi-banding 10 tons per acre of composted municipal waste under sugarcane rows or placing 40 tons per acre of the compost on top of cane in opened rows at planting can result in increased sugar yields.
It is like turning a sow’s ear into a silk purse. Participants in the LSU Agricultural Center’s semiannual compost facility operator training school learn to transform garbage into something valued by society.
Can poultry litter be used to fertilize cotton? That’s thequestion an LSU Agricultural Center researcher will attempt toanswer with a new project in northwest Louisiana cottoncountry.
Sewage sludge was the first non-farm organic material to be applied to farm land in large quantities, and it became the first organic material whose application was covered by federal regulations. States now also have regulations governing the land application of sewage sludge.
Certain soils in the southern states may have low pH, low organic matter content and natural shallow hard pans that limit root development.
Research at the LSU Agricultural Center and other land grant universities has shown that non hazardous industrial wastes can be used to enhance the productivity of crops,especially forage crops
This issue of Louisiana Agricultureis devoted to Louisiana Agricultural Experiment Station (LAES) research programs that focus on the beneficial recycling or reuse of organic wastes.
To many gardeners and horticulturaloperations, organic matter is considered“black gold.” Since ancient times, it hasbeen used both as a mulch on top of thesoil and as an amendment incorporatedinto the soil.
Automobile tires are accumulating in waste dumpsthroughout the United States. Research exploring the useof shredded tires could reduce the number of waste tires.One use is in horticulture
Beneficial use in agriculture of organic wastes generated by municipalities, industry and agricultural commodities is receiving considerable attention as an alternative method of disposal because of the rising costs and environmental concerns associated with present disposal methods.
Disposal of solid waste is a growing concern to municipal officials and corporate managers, and in some sections of thecountry, critical. As the population grows and industrial productionincreases, so does waste. At the same time, disposal costs have increased, often dramatically, because of increased regulationand centralization of waste disposal sites.
