Profitability on grass-based systems is driven by degree of grass utilisation. This is influenced by increased growth and optimum management of that growth. Frequent measurement of grass parameters, e.g., herbage yield, height and density, will facilitate increased herbage production and utilisation. The project ICTGRAZINGTOOLS developed a grass measurement system known as Grasshopper. It incorporates a rising plate meter, an ultrasonic sensor and a data analysis/management system that can also map land areas. The technology measures compressed grass height precisely and transfers that information with GPS coordinates to a smart device. Herbage yield in the paddock is calculated and this data is then used to automatically define the appropriate area of the mapped paddock to allocate the cow herd. The data can also be uploaded automatically to the decision support tool PastureBase Ireland. The ICT tool Grasshopper is commercially available and used for grass measurement on up to 500 farms, and it has been adopted in several countries including Ireland, UK, France, Germany, Switzerland, Belgium, the Netherlands, Luxembourg, Italy, New Zealand, and Denmark. It has contributed significantly to the promotion of the decision support tool (DST) PastureBase Ireland (used for decision making on grassland and grazing management). Grasshopper uploads to any database and current users can upload to several databases, extending its utility to European and worldwide markets. Through its ease of use and automated elements, Grasshopper has increased the number of farmers conducting grassland measurement at farm level.
