Strong winds may affect your spread pattern, especially if you’re spreading lighter prills. Our simple advice: if it is too windy to spray, don’t spread either. Keep an eye on humidity levels too; on a damp day fertiliser can absorb moisture, which will affect flow rates. Damp or humid conditions will also affect sulphur products, causing them to build upon the vanes quicker than in dry conditions.
Speed plays an important role in achieving a constant application rate, so the correct gear must be used. With machines that rely on PTO or ground drive to operate the disc, always travel at the recommended forward speed. Variations will produce uneven spread and variable application rates.
The right bout width
It is most important to set your spreader to the correct working width to achieve the right overlap pattern. The manufacturer’s handbook will give this information for the type of fertiliser which is to be used. For full-width distributors, each bout should match up with the previous one.
It is usual to leave enough space for two bouts around the field. With lateral spread machines it is essential that the ‘switch-on’ and the ‘switch-off’ of fertiliser is aligned to avoid double-dosing or missing. Use the headland disc or border device supplied with the machine. Take into account application restrictions on field margins and set the headland device accordingly. Pay special attention where you have watercourse adjacent to field boundaries.
Fertilisers are used most effectively when your crops need them most. Trial data has shown that crops benefit from a spring application of N, P&K, and S, as that is when their demand for these major nutrients is at its highest, getting your crops off to a great start.
These short stories will show you why and how choosing the right fertiliser and ensuring the nutrients are spread accurately and evenly pay off. Here is our advice on how to protect your investments as well as the environment:
