South Downs Chalk Groundwater Pilot
In the Downs and Harbours project area there are two field trials were undertaken both looking at cover cropping to reduce nitrate leaching into groundwater. To find out more about these trials click on the case studies below.
To quantify the impact of contrasting cover crop mixes and destruction techniques on over winter nitrate leaching, soil nitrogen supply (and hence crop nitrogen fertiliser requirements) and performance of the following cash crop. In particular to determine the:
effect of cover crop species mix on the quantity and timing of nitrogen returned to the soil
effect of cover crop destruction method e.g. glyphosate & min till/direct drill vs mechanical destruction & min till/direct drill
To determine the timing of nitrogen release from cover crops and potential legacy (year 2) effects on nitrate leaching and crop performance
