Winter Feed Crops: Management After Grazing
Careful management of paddocks after winter grazing can reduce damage to soil structure and loss in productivity, while reducing further environmental losses that could potentially affect water quality.
Critical Source Areas
Critical source areas (CSAs) are small, low-lying parts of farms such as gullies and swales where runoff accumulates in high concentration. This site gives options to manage CSAs to reduce runoff losses

A guide to reducing contaminants entering tile drains
Many farms in Southland are dependent on an efficient soil drainage system to maintain pasture production and use. This is made up of subsurface mole and tile (pipe) drains that transport soil water to open drains and waterways.

Nutrient Management
Environment Southland is promoting the use of a nutrient budget as good management practice to ensure farmers gain a greater awareness and understanding of nutrient management for their farm.

Nitrogen and Phosphorus Filter Trials
Two filters were installed near the Waituna Lagoon in 2016 and were monitored for 3 years. This website explains how the trial was conducted, the potential of filters as a mitigation and the practicality of including this mitigation on farm

Water, soils and wallowing
Deer have specific natural needs and behaviours and if incorrectly managed, deer can threaten the quality of water and soil, cause erosion, compaction and pugging of soils, and the consequent runoff of nutrient, sediment and coliforms will result in contamination of waterways with undesirable behaviour including excessive pacing, wallowing, and digging in soils.

Phosphorus fertiliser use
Phosphorus (P) is the most expensive nutrient. It is also a pollutant when it gets into waterways. Careful management of P is essential to ensure optimal economic and environmental outcomes. The key is to farm at the economic optimal soil Olsen P – farming below the optimal means less profit and farming above the optimal means greater losses of P to the environment.
