- Fertiliser use: responses to nitrogen and phosphorus
Matching stocking rate and animal productivity to the farm pasture production potential and additional supplementary feed is a strategic decision, i.e. planned at the start of the season. However, as well as a strategy, a farm needs tactics to achieve its goals.

- Storing carbon in soil
There are several important reasons for maintaining or increasing the carbon content of soils. Organic matter is critical for supporting many important soil functions that contribute to production and protect the environment. These include improving soil structure, nutrient and water retention, and providing a food source for soil microorganisms.
- Forage VaIue Index – the science
DairyNZ, in collaboration with NZPBRA, has developed an economic Forage Value Index (FVI; $/ha). This allows farmers and advisors to compare perennial ryegrass cultivars in overall economic terms for seasonal dry matter (DM) production.
- Keeping your cows cool
Summer heat does affect cows throughout New Zealand. By ensuring farm infrastructure and stock management practices assist cows to reduce heat load, appetites can be sustained and summer milk production increased.
