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.
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.
Reducing phosphorus (P) loss on dairy farms
There are many options to reduce the amount of P that enters the environment. This page will help you identify opportunities on your farm to reduce P loss.
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
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.
