Abstract: | Trials are described in which various mechanical treatments of hay in the field were compared. Cutting the crop with a forage harvester resulted in very rapid drying of the hay, but this was accompanied by very high nutrient losses. When the crop was tedded with the harvester the hay dried more quickly than with conventional ledding, the nutrient loss being similar for these two treatments. Tedding with either a harvester or a conventional machine appeared to increase the loss of nutrients compared with less severe treatment, but this loss appears to be acceptable as tedding considerably reduces the risk of the hay being weathered. |
