Many efforts are made to evaluate the fertiliser demands of crops by analysing soils and plants and to establish recommendation schemes. But when it comes to the application of nutrients in the field all operations are done more or less blindfolded because a: the analysed samples are taken randomly, they can never reflect the true spatial variability in the soil environment and b: fertilisers are distributed evenly which result in a side by side of ecological and economical oversupply and undersupply of the plants. LRM is a more consistent term for what is handled outside Germany as "precision farming". LRM is based on the idea that addressing the spatial variability of soil fertility parameters is the most promising approach to improve the utilisation of inputs towards a more sustainable agriculture. The use of nutrients is a good example to highlight the problems for which LRM will be the future solution.
