Calibrate fertiliser and manure spreaders

Accurate calibration of fertiliser and manure spreaders ensures even nutrient distribution, improves application efficiency, and reduces costs and environmental risks. Proper calibration prevents over-application, minimizes nutrient runoff and leaching, and supports sustainable crop production. It is essential for compliance with environmental regulations and maintaining water quality. Calibration procedures differ for mineral fertilisers and manure due to material characteristics, with methods including the load-area and tarp techniques for manure. Regular calibration accounts for equipment wear, changes in manure consistency, and varying fertiliser types. Detailed guides and worksheets are available from agricultural advisory services and equipment manufacturers. Electronic calibration systems are also available for modern spreaders.
