On the mixed livestock farm Močnik in Veliki Hrib pri Lazah in Tuhinj (lat. 46°13' N long. 14°46' E, alt. 610 m) we conducted survey in 2022 with the aim of what the floristic and botanical composition is, how different the yield and quality of herbage are, and the usage of a satellite surface monitoring application for the purpose of mapping potential crop growth. The grasslands were divided into six units based on cultivation practices, terrain slope and soil characteristics. For each unit separately, the grassland was evaluated in the spring for the purpose of floristic and botanical composition. Most meadow units are fertilized with moderate doses of animal manure. The annual dry matter yield on the studied meadow units in all three cuttings ranged from a minimum of 0.50 t/ha (Reber hrib) to a maximum of 12.24 t/ha (Reber ravnina). At the 1st cut, the highest yield (8.58 t/ha) was on the Reber ravnina and the lowest yield (0.29 t/ha) on the Reber hrib. At the 2nd cut, the highest yield (3.66 t/ha) was achieved by the Reber ravnina unit and the smallest (0.18 t/ha) by the Osovje unit. At the 3rd cut, the highest yield was on unit Brsevnica (0.54 t/ha), followed by unit Močile (0.46 t/ha) and the lowest yield was recorder on unit Osovje (0,11 tha). Forage quality was very different and was between 4.56 MJ/kg DM and 6.3 MJ/kg DM for net energy of lactation and between 95 and 129 g/kg DM for crude protein. Grasses were the dominant functional group, accounting for 45.2% to 74.3%, followed by herbs, which ranged from 9.1% to 72.0%. Legumes were the least prevalent, comprising only 1.2% to 25%.The number of species ranged from 16 to 35 per meadow unit, and Shannon's diversity index was between 1.00 and 1.98.
