Fertiliser application plays a vital role in the success of any agricultural operation. When applied correctly, it boosts soil health, improves crop yields, and maximises profitability. However, even experienced farmers can make small mistakes that lead to waste, poor growth, or even environmental damage. Understanding these common errors and how to avoid them can save time, money, and effort across the season.
Here are the top five fertiliser spreading mistakes and how to fix them.
Are You Ignoring Calibration Before Spreading?
Calibration is one of the most overlooked steps in fertiliser application. Spreader equipment that isn’t correctly calibrated can lead to uneven distribution, resulting in over-fertilised patches and undernourished areas. This not only reduces crop uniformity but also wastes valuable product.
Calibrating your fertiliser spreader involves adjusting the machine to release the right amount of fertiliser per hectare based on the granule size, density, and spread width. This should be done at the start of each season and after any change in fertiliser type or spreading speed. Tools like test trays and weighing scales can help you verify accuracy before hitting the paddock. Learn more about our fertiliser spreading services for professional support.
Is Wind or Weather Ruining Your Application Timing?
Weather conditions, particularly wind and rain, can significantly affect fertiliser effectiveness. Windy days can cause fine granules or liquid sprays to drift, missing their target entirely. Meanwhile, rain shortly after application can lead to runoff, especially on sloped ground, washing nutrients away before they can be absorbed by the soil.
Always check the weather forecast before spreading. Aim to apply fertiliser when wind speeds are low and no rain is expected for at least 24 to 48 hours. Dry conditions followed by light rain are often ideal, allowing fertiliser to settle and then activate with moisture. If you use granular fertiliser, consider how weather may influence its performance on your specific terrain.
Over-Applying Fertiliser Without a Soil Test
Applying more fertiliser than necessary doesn’t guarantee better results, in fact, it often causes the opposite. Excess nutrients can burn plants, unbalance soil chemistry, and increase the risk of leaching into waterways.
A soil test provides crucial insights into nutrient levels and pH balance, helping you determine exactly what your paddock needs. With this information, you can tailor your fertiliser plan to specific deficiencies and avoid wasting money on unnecessary inputs. For certain conditions, gypsum for soil can be a valuable amendment to improve structure and manage salinity.
Are You Using the Wrong Fertiliser for Your Soil Type or Crop?
Not all fertilisers are created equal. Using the wrong product can limit crop uptake or even damage your soil over time. It’s essential to match your fertiliser to your crop’s growth stage, soil conditions, and local climate.
For example, nitrogen-rich fertilisers are beneficial during early growth stages, while phosphorus and potassium support root development and fruiting. Consider whether a granular or liquid fertiliser is better suited to your spreading equipment and crop type. You can also explore options like agricultural lime to correct soil structure and pH issues.
Are You Forgetting to Clean or Maintain Your Spreading Equipment?
Your fertiliser spreader works hard, and regular maintenance is key to keeping it accurate and reliable. Worn-out or clogged parts can affect flow rates and distribution patterns, leading to inconsistent application.
After each use, clean your spreader thoroughly to remove dust, residue, and moisture. Check moving parts, nozzles, and agitators for wear or damage. Before storage, lubricate key components and protect exposed metal surfaces from corrosion. Well-maintained equipment not only performs better but lasts longer, saving you costly replacements in the long run. If you’re looking to streamline application, consider our fertiliser blending for customised nutrient mixes.
Best Practices to Get the Most Out of Your Fertiliser
Avoiding common mistakes is only half the battle. To truly maximise fertiliser efficiency, consider adopting some tried-and-true best practices:
- Use overlapping spreading patterns to ensure full coverage without over-application.
- Implement GPS-guided spreading systems for higher precision.
- Keep detailed records of when, where, and how much fertiliser you’ve applied to monitor results over time.
