Agro Fossil Free - Improving productivity and increasing the efficiency of soil nutrient management on grassland farms in the UK and Ireland using precision agriculture technology

Opis ogólny

Grass growth and utilisation on grassland farms across the UK and Ireland are below their potential, and nutrient management is sub-optimal. Excessive soil phosphorus concentrations are an issue, contributing to eutrophication of waterways, while sub-optimal soil pH due to a reduction in lime use is seen in many areas. This paper discusses the potential for introducing technology onto grassland farms, and implementing sensible farm-specific management decisions as a means of enhancing productivity and minimising the environmental impact of livestock farming. The adoption rate of Precision Agriculture (PA) technology by grassland farmers in the UK and Ireland is still relatively low, and significantly lagging behind the advances that have taken place within the arable farming community. With rapidly advancing technology and investment in research, there are now a range of soil sensors available along with technology for grass growth monitoring, yield mapping, remote sensing, satellite imagery, and devices for tracking animal movement, behaviour and feed intake. In this review paper we examine the latest technology developments specific to grassland farming and we question their suitability and ‘readiness’ for adoption by farmers. The review identifies the challenges that are specific to grassland such as complex soil, vegetation and climatic variables along with economic barriers that may be preventing change within the farming community in these areas.
