The effectiveness of chemical amendment of pig slurry to ameliorate phosphorus (P) losses in runoff is well studied, but research mainly has concentrated only on the runoff pathway. The aims of this study were to investigate changes to leachate nutrient losses, soil properties and greenhouse gas (GHG) emissions due to the chemical amendment of pig slurry spread at 19 kg total phosphorus (TP), 9...

Sucrose losses after cane harvest is one of the most important problems in sugarcane crop particularly for millers and farmers. Loss in sucrose after harvesting causes low sugar recovery in mills. There are a large number of factors associated with low sugar recovery such as varietal type, atmospheric conditions, time lag, etc. Sucrose losses occurring in postharvest sugarcane are generally of ...

Horse paddocks have been identified as a significant contributor of animal waste nutrients to natural waters; thus, modified paddock management is needed. Because chemical amendments pose a health risk to horses, an alternative for reducing nutrient translocation from manure is to add available organic residues to the soil. To examine the feasibility of outdoor use of organic materials to reduc...
