Weed ascendance in muckle and container culture is a challenge for many growers . Due to the limited lotion possibilities of pesticide , a lot of time must be spent on weed weeds and moss during finish and manner of speaking work .
Nowadays there are more and more different covering materials on the market to protect against sess and moss . Which covering material is chosen depends , among other things , on the cultivation organization , the method acting of fertilisation and the customer ’s indirect request . In 2019 , the Delphy Tree Nursery Research Center set up a trial with eight different types of covering materials . TheTopControlcovering fabric from Van der Knaap was also include .
TopControlTopControl consist of pressed flax grains that fall aside after tangency with water and make a covering layer . After a single irrigation , the compressed pellet take on their original volume . The fibre interlock , creating a uniform cross layer . This layer remains entire , even if the plants topple over by wind . The material will darken after a few months . The TopControl bed is moisture- and air permeable and dries very quickly . Weed seeded player have no prospect to burgeon forth , due to the speedy drying . There is also no chance for moss formation on the culture layer .
The trialDuring the test , various cover material were applied right away after potting according to the instructions for use of the producer or provider . Thuja were potted in March and grow in a lava container field until the finished Cartesian product was available in November , adequate to the situation in practice . The mourning band that managed to settle were regularly removed during finish to test the performance of the covering materials . The ( fresh ) weight and type were record .
upshot / conclusionThree observance rounds were conducted . This showed that all covering materials are very effective and the results showed no substantial remainder between the test material . On TopControl , the researchers report a stable product with a beautiful rude appearing . “ It sit nicely on the pot and the cloth darkens over time . Because it is pitch in dried and press descriptor , a big aerofoil can be covered with a relatively modest book ” , say the Nursery Research Center .
TopControl is suitable for near all crops and can be used in various growing system . It is comfortable to march , both automatically and manually , and is easy to utilise even after pot . In plus , it shorten drying up , which stimulate it potential to save on irrigation water supply .
