Winter grazing of forage crops is a key land-use in southern New Zealand, providing important feed for livestock but has been identified as risky if not managed well, potentially resulting in soil degradation and nutrient losses. We hypothesised that

Soil structure is critical to soil quality due to its influence on many soil processes and functions, including water storage and transport, the oxygen supply, the emission of greenhouse gases, and biological processes such as carbon and nitrogen min

Research in New Zealand indicates that winter forage grazing on steep land creates a high risk of sediment loss. This loss can have a significant impact on sediment and associated nutrient content of waterways. A national-scale map of winter forage c
