Composted Cattle Manure Increases Microbial Activity and Soil Fertility More Than Composted Swine Manure in a Submerged Rice Paddy
Livestock waste composts with minimum inorganic fertilizer as a soil amendment in low-input intensive farming are a feasible agricultural practice to improve soil fertility and productivity and to mitigate soil degradation. The key benefits of the practice rely on the activities of soil microorganisms. However, the role of different livestock composts [composted cattle manure (CCM) vs. composte...
متن کاملPhosphorus extractability of soils amended with stockpiled and composted cattle manure.
Managing fertilizer applications to maintain soil P below environmentally unacceptable levels should consider the contribution of manure and synthetic fertilizer sources to soluble and extractable forms of P. Our objective was to evaluate soil and manure characteristics and application rates on P extractability in recently amended soils. Five soils of the U.S. southern High Plains were amended ...
متن کاملMANURE Mineralizable Carbon, Nitrogen, and Water-Extractable Phosphorus Release from Stockpiled and Composted Manure and Manure-Amended Soils
Much of land-applied manure is surface-broadcast or incorporated to a shallow depth of fields under crop Dissolved N and P transfer to runoff water may increase with residue and conservation tillage management because of surface applications and shallow soil incorporation of animal manure. Information is needed regarding water-extractable nutrient release the need to conserve stored soil water ...
متن کاملSoil Physical Properties and Crop Productivity of an Eroded Soil Amended with Cattle Manure
Erosion changes soil properties, especially physical properties, mainly because it removes surface soil rich in organic materials and exposes lower soil layers. In 1988, a study was established to determine the effects of soil erosion and long-term manure applications on selected soil phys ical properties and corn (Zea mays L.) production. After 10 years of an nual manure applications, soil c...
متن کاملSoil Microbial Community Dynamics as Influenced by Composted Dairy Manure, Soil Properties, and Landscape Position
Manure applications can benefit crop productivity by adding required nutrients and organic matter to soil. There is a paucity of information on how soil microbial community dynamics will be altered by the application of manure to different landscape positions. Thus, an in situ field study was conducted during the summer and winter months to evaluate microbiological properties of three soil type...
