The innovation in the farm is bridge irrigation system applied on ryegrass dominant temporary grasslands. Thanks to irrigation the high application of fertilizers is possible leading to obtain high yield of DM and necessary amount of silage for dairy cows TMR feeding. The irrigation system (max. flow 45 m3/h, typical dose 15 l/m2) is working on two fields each 220 m width prepared specially for field size. It is driven by an electric generator. Water is obtained from deep wells and mid-field ponds. The watering dose is determined according to daily requirement.
Reason for the innovation
The farmer manages the dairy farm in specific habitat condition – light sandy soil, strongly permeable (low water retention). Such conditions did not allow for obtaining high-yields of grassland sward and stable production of feeds, especially in the case of drought periods. The farmer, through his own deduction and searching for a problem solution, decided to install an irrigation system on the farm. The first attempts to irrigate grasslands were made using reel-operated sprinklers. This solution gave good results, but it was very labor-intensive and expensive. Finally, the farm decided to implement a large investment and install a ramp transferred semi-automatic irrigation system. This solution allowed for the independence of forage production from weather conditions, and it has let to the possibility of using new grass mixtures containing high-yielding species and varieties. These elements together with the introduction of an efficient technology of harvesting and feed conservation technique allowed not only to maximize the production of feed but also to reduce its unit production costs. In the results the farmer achieves milk production at a very high level.

Why it is working
Farm is located in a specific habitat characterised by light sandy soils, in which periodic droughts occur. Thanks to the innovation forage production from irrigated and high-fertilized grassland is secure. The intensive grassland production allows to maximize the milk yield in the farm.
