North Wyke Research in Devon are using SampSys samplers for studying controlled sections of farmland.

In this Defra funded study, run-off and ground water from nine individual hydrologically isolated areas are being closely monitored to see how different land management techniques, including buffer strips, ponds and ditches, can control a range of pollutants such as nitrate, ammonium, phosphorus, and suspended sediment.

The SampSys sampler can be linked to either analogue or digital signals to start sampling routines or to pace sample events. In this instance, the sampler is being triggered by level devices installed in weirs that are designed to capture and measure the run-off and ground water flow.

The SampSys is ideal for this type of work due to the robust construction and ease of use in the field. Sampling data can be collected from the samplers and loaded onto a laptop computer for quality control.

The sampler will collect 24 samples in one-litre bottles during a storm event for eventual analysis of Suspended Solids, total Phosphorus, Nitrate, and Ammonium content.

North Wyke has a 250 ha research farm with extensive facilities where there are opportunities to undertake experiments on contrasting ways of managing grassland agriculture. Established in the pastoral landscape of central Devon in 1981, it has recently merged with Rothamsted Research to provide an integrated approach to research and innovation in grassland and arable systems.
