| Popis: |
The use of pig slurry (PS) as a fertilizer has been practised for a long time. Direct application to soils at an adequate level influences the soil organic matter and quality positively, a critical component of soil fertility and productivity. Organic manure is considered as a source of slow-release nitrogen (N) fertilizer. High initial applications to build up the organic pool and cut back in subsequent years would be appropriate. In supplying the nutrient requirements, the amount of manure applied can be calculated based on the rate of N applied and the rate of organic N mineralization in the application season. There are many factors to be considered when attempting to assess the overall net impact of a management practice on soil quality and productivity. Additions of manure to soils at agronomic rates to match crop nutrient requirements are expected to have a positive impact on soil quality and productivity. Salinity impacts and overloading of both functional and non-functional elements can negate these benefits when manure is overapplied or applied to soils with limitations in drainage and buffering capabilities. |
