Summary
The North Wyke Farm Platform represents a nationally significant, intensively instrumented research facility designed to investigate how different grassland management practices affect agricultural productivity and environmental outcomes in lowland beef and sheep systems. Using a combination of sensor technologies and traditional field methods, this case study demonstrates the capability to detect effects of pasture renewal (through reseeding with improved grasses or legume mixtures) on nutrient losses and water quality dynamics. The platform's unique scale and scope enable detailed investigation of how meteorology, topography, and farm management practices interact to influence soil moisture, runoff, and associated pollutant losses.
UK applicability
The findings are directly applicable to United Kingdom lowland grassland farming, as the research was conducted on a UK national capability using representative beef and sheep production systems under temperate conditions. The investigation of legume-based and improved grass varieties has immediate relevance to UK efforts to reduce nitrogen fertiliser inputs whilst maintaining productivity.
Key measures
Soil moisture contents; surface runoff volumes; nutrient (nitrogen) losses to water; pollutant concentrations in runoff; nutrient cycling dynamics; field topography effects on runoff; weather effects on hydrological and nutrient outcomes
Outcomes reported
The study measured the effects of different grassland management practices (permanent pasture, reseeded grasses with enhanced traits, and grass-legume mixtures) on soil moisture, surface runoff, nutrient losses, and water quality dynamics using sensor technologies and traditional field methods. The research evaluated nutrient cycling and flows to water and losses to air across three 21-hectare farmlets under beef and sheep production systems.
