German maker Rauch has developed a fertiliser slope compensation system to help growers spread fertiliser accurately on hilly ground.

The system works by using a gyroscope on the spreader to measure the working angle, and it combines this with information from the GPS system.

By doing so, it can adjust the drop point of the fertiliser on the disc to maintain the required spread pattern, either on a side slope or when working directly up or down a hill.

The technology is still in development, with testing currently taking place in Germany. A realistic timescale of 2021 has been put in place for sale, but the good news is that it should be possible to retrofit on older machines.
