Reference conditions and threshold values for nitrate-nitrogen in New Zealand groundwaters
Management of groundwater quality is assisted by an understanding of reference conditions, which describe the concentration ranges expected for key substances in the absence of…

Linking the uptake of best management practices on dairy farms to catchment water quality improvement over a 20-year period
Intensive land use, such as dairying, can impair water quality. Although many guidelines exist on how to mitigate the loss of dairy-associated contaminants from land…

Can green crops capture enough nitrogen for vegetable growing?
Nitrogen fertiliser use is becoming increasingly restricted and expensive, so vegetable growers are looking for new methods to manage the high nitrogen demands of their…
Technical Report
Spring milling wheat as a ‘nitrogen scavenger’ in the North Island
The use of wheat in the farm system should be considered as an effective nitrogen (N) mitigation technique. Wheat as an N scavenger crop does…
Guidance
Using variable rate irrigation to mitigate nutrient losses
Variable rate irrigation (VRI), where the application rate of irrigation water across an area changes depending on soil type and other factors, can also decrease…
Guidance
Excluding stock from smaller streams
This factsheet is for farmers, industry bodies and regional authorities developing regional freshwater policy. Most of the contaminant load in waterways across New Zealand originates…
Interactive Tool
MitAgator
Built on a detailed farm map, MitAgator’s software gives a spatial view of where contaminant losses are occurring and identifies critical source areas (CSAs). Targeting…
