The problem 

Recent Defra-funded research has shown conclusively that over 80% of over-winter losses of suspended and total sediment, total phosphorus and total nitrogen in surface runoff, on moderate slopes, are associated with unvegetated and compacted tramline wheelings. Latest results show that disrupting compacted tramlines using a cultivator after spraying autumn-sown crops is a highly effective method for reducing runoff and associated pollutant losses

Project aims 

The project aims to design, prototype and test the efficacy of practical and cost effective engineering solutions for reducing runoff and associated diffuse pollution from tramline wheelings in combinable crops.

Benefits to the industry 

The main benefit to the industry is the development, evaluation and refinement of practical engineering solutions for tramline management which are both cost effective and fully compatible with agri-environmental policy. The project will also provide guidance for farmers on targeted management of tramlines in cereal cropping systems.
