Accurate Spreading of Fertiliser and Manure: Lessons from UK Practice

Keywords: fertiliser spreaders, manure spreaders, application, accuracy.

Based on training material for the BASIS FACTS Continual Professional Development scheme in the UK, this paper provides practical guidance concerning good practice for the accurate spreading of fertiliser, slurry and manure. It discusses the consequences of the two main problems that can occur during spreading fertiliser, namely the wrong rate of application and uneven spreading, and discusses in detail the specific actions needed to minimise these. Data is shown on current spreading practices in the UK. The impact of evolving spreader capability is reviewed, along with the opportunities being provided by emerging digital technologies.

Current UK practices regarding the spreading of organic manures and slurry are outlined, and the requirements for accurate application are compared to these practices. The detailed requirements and good practice for even application are described. The particular requirement to minimise ammonia losses is discussed, and good practice explained. Finally, developing spreader capabilities and technological aids for even spreading are covered.
