Grasslands, with about 40% coverage of entire Earth’s surface as a source of valuable animal food in situation of still increasing cost of production are in need of special care concerning its performance, conservation and productivity. In times of intensive production and decreasing arable areas and increasing costs of animal production, diversified and quality management is required for grasslands. Highly developed precision farming tools, commonly used in cereals crops, especially remote sensing, allowing nondestructive, fast and accurate monitoring during grow season, can be adopted to grasslands in the framework of organic animal husbandry as well. Aim of this article was attempt to check remote sensing of grassland biomass as precision, high-performance and low-cost substitute of currently developed method with use of handheld biomass meter-herbometer. Research has shown that there is possibility to find mathematical relationship between the NDVI values and the grass height in the pasture.
