At the block level Leaching-other is the leaching from the inter-urine patch areas. It incorporates the effects of soil fertiliser, effluent and other nutrient input sources. Leaching - other is reported in the Nutrient Budget under Leached from root zone. This can be particularly affected by the level of inorganic N in the soil and the level of drainage occurring in the block.
The higher the level of inorganic N, and the higher the drainage - the higher the Leaching-other will be.
In the farm level nutrient budget, leaching - other is the area-weighted average background losses from the blocks, plus losses from lanes, unlined standoff pads, effluent storage system, wintering pads and silage stacks. Some of this loss may occur as runoff, particularly for P, but there was insufficient information to split between runoff and leaching when the model was developed.
