Spring is a critical planning period for New Zealand farmers. Decisions made now can have a significant impact on how well your farm handles the months ahead.
With forecasts continuing to highlight the possibility of El Niño conditions, many farmers are asking the same question: What should I be doing now to prepare?
The challenge is that no two seasons unfold exactly the same way. While El Niño is often associated with drier conditions in many parts of New Zealand, its effects can vary considerably between regions and even between neighbouring farms.
Rather than trying to predict exactly what will happen, the most effective approach is to prepare for a range of scenarios and put yourself in a position to respond early.
According to the National Institute of Water and Atmospheric Research (NIWA), El Niño typically brings stronger southwesterly and westerly winds to New Zealand. Eastern regions are more likely to experience drier conditions, while western areas can often see increased rainfall.
For many farmers, the biggest risk isn't a single weather event. It's a gradual reduction in soil moisture over spring and summer that limits pasture growth and increases pressure on feed and water supplies.
The exact impact will depend on where you're located, your soil type, and how much moisture is already in the ground heading into the season.
Regional forecasts are useful, but they don't always reflect what's happening on individual farms.
A farm with heavier soils may retain moisture longer than one with lighter soils. Irrigated paddocks will respond differently from dryland areas. Even neighbouring properties can experience different growing conditions depending on rainfall, soil type, and management practices.
That's why it's important to keep track of conditions on your own farm rather than relying solely on regional weather updates.
One of the first areas worth reviewing is your feed budget.
Consider:
Feed is often easier and cheaper to secure before widespread dry conditions develop.
If dry conditions develop, water can quickly become a limiting factor.
Now is a good time to review:
Knowing where your pressure points are before summer arrives makes it easier to prioritise management decisions.
Fertiliser performance is closely linked to soil moisture.
If soils become too dry, plants may struggle to take up nutrients and pasture response can be reduced. If conditions become very wet, nutrients can be lost through leaching or runoff before plants have a chance to use them, meaning you will have paid for nutrients that your pasture can't fully use.
Review your fertiliser programme and consider:
Understanding what's happening in your soils can help you make more informed fertiliser decisions throughout the season.
A contingency plan doesn't need to be complicated.
Start by identifying:
Having these decisions mapped out in advance can help reduce stress and improve response times if conditions change quickly.
By the time pasture growth visibly slows, valuable time may already have been lost.
Monitoring soil moisture and paddock conditions can provide an earlier indication of changing conditions, giving you more time to adjust irrigation, grazing, feed and fertiliser decisions.
The earlier you identify a developing issue, the more options you have available.
No one can control what the season brings. But farmers who can see how conditions are changing across their farm are often in a stronger position to respond.
Understanding what's happening below the surface helps take some of the guesswork out of seasonal decision-making and provides greater confidence when conditions become challenging.
With El Niño conditions forecast, now is a good time to review your plans and make sure you're ready for whatever the season delivers.
