Trial purpose
The greens of golf courses often suffer from salt stress as a result of long-term use of mineral fertilisers, insufficient or poor‑quality irrigation water, and/or suboptimal soil conditions. When these factors are combined with prolonged periods of drought, grass comes under severe stress. In such situations, REDU-ACT® can provide a solution. To measure the effect of REDU-ACT®, a trial was set up in a controlled environment in which chewings fescue was sown in a sandy substrate suitable for greens. Salt stress was then deliberately induced.
Proefopzet
Crop: | Chewings fescue (Festuca rubra commutata) |
Product: | |
Application method: | irrigarion water application |
Period: | 4 months in a growth chamber |
location: | Scientia Terrae laboratory |
Results
Artificial salt was artificially induced. After the treatment with REDU-ACT® and subsequent watering, the salt was washed away and soil analysis showed a significant decrease in EC values. The salt stress immediately reduced. About 2 weeks later, the grass with REDU-ACT® looked well recovered and denser again. This illustrates the positive effect of the dual mode of action of REDU-ACT®.
