Effect of deficit irrigation and fertilization on cucumber
Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

A new method of poultry litter application to perennial pasture: Subsurface banding
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear applications is limited. Therefore, two experiments, one in ...

In-situ comparison of phosphorus losses between organic and inorganic fertilizersPhosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed ...

Intake and digestibility of ‘Coastal’ bermudagrass hay from treated swine waste using subsurface drip irrigation
Waste handling systems for confined swine production in the upper South (approximately 32–37° N and 79–93° W) depend mainly on anaerobic lagoons and application of the waste effluent to cropland. The main objective of this study was to evaluate the quality of ‘Coastal’ bermudagrass [Cynodon dactylon (L.) Pers.] hay receiving effluent generated from a raw swine waste treatment system designed to ...

Modifying broiler diets with phytase and vitamin d metabolite (25-OH D3): impact on phosphorus in litter, amended soils, and runoff
Received for publication April 14, 2009. Adding phytase and 25- hydroxycholecalciferol (25-OH D3) to broiler diets has been shown effective at reducing total P concentrations in broiler litter. This study was conducted to determine the impact of field application of broiler litter from modified diets on P solubility in litter-amended soils and P losses in runoff. Five broiler diets and their ...

How to compost pig manure into high quality organic fertilizer?
As we all know, fresh pig manure is rich in organic matter, but also contains a lot of volatile substances, pathogenic microorganisms, parasite eggs and heavy metals. In addition, fresh pig manure can produce an unpleasant smell. Therefore, unfermented pig manure cannot be used directly. But managed pig manure is free of odors and bacteria or parasite eggs. At the same time, bacterial protein and ...

Should access to phosphorus be a human right?
Food is a fundamental human right, as set down by international human rights treaties and, often, national constitutions. But the right to food cannot be ensured without a corresponding right to phosphorus, as some scientists pointed out at the Sustainable Phosphorus Summit 2014 earlier this month in Montpellier, France. The idea of phosphorus as a human right is intriguing. While there are ...

Effects of agricultural production on phosphorus losses from paddy soils: a case study in the Taihu Lake Region of China
A field plot experiment was conducted on two types of paddy soils in the Taihu Lake Region of China from June 2000 through 2002 to assess phosphorus (P) losses by runoff and drainage flow and the effectiveness of rice–wheat double cropping on reducing P losses from paddy soils. Commercial NPK compound fertilizer and single superphosphate fertilizer were applied to furnish 0, 30, 150, and 300 kg P ...
