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.
Considering a catch crop
The purpose of a catch crop is to increase annual dry matter production, to take up soil mineral and urine nitrogen and to reduce the risk of leaching or runoff.

Reducing Nitrogen Fertiliser Use
Using less N fertiliser can contribute to better water quality and a reduction in greenhouse gas emissions. If reviewing your use of N fertiliser, the tips below can help you form a plan.

Forages for reduced nitrate leaching programme
The DairyNZ-led programme Forages for Reduced Nitrate Leaching – a cross-sector approach (2013-2019) provided new scientific knowledge, tools and technologies for forage production that can amount to more than 20% reduction of nitrate leaching from dairy, arable, sheep and beef and mixed-farming systems.

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

Natural seepage wetlands and nitrogen losses
They may be generally disliked by farmers and thought of as troublesome ‘bogs’, but seepage wetlands have proven highly effective at preventing contaminants from reaching waterways. These so-called ‘kidneys of the land’ could serve as one useful tool in the dairy sector’s efforts to reduce nitrate leaching.
