LOCATION EFFECTS OF WINTER-GRAZING REGARD ING AGRONOMICAL ASPECTS

Winter-grazing can be variable-organized, the possibilities of adjustm ent to the specific predominant conditions are to be utilised conseque ntly. During the frost free time a prerequisite of of winter-grazing i s a soil with sufficient holding capacity. kt the feeding and resting places nutrients might accumulate, this should be minimised by changes of the feeding places as well as bedding of the resting places. Arabl e and straw folds are alternative to an insufficient holding capacity of the soil. Sufficient bedding, not too high stocking rarer as well a s limited folding days prevent agronomical not manageable high nutrien t accumulations in the upper soil layer. Appropriate species stockpile d for a winter-grazing are those which growth stays green and does not decay during winter; Festuca arundinacea (tall fescue) shows special advantages when accumulated from August. Straw, hay and silage are con servation possibilities. When producing hay and silage from extensive grassland some peculiarities regarding conservation losses and forage quality are to be considered. Stalk rich material in connection with g reat quantities affects the drying time and an extremely low nitrate c ontent favours erroneous fermentation. The body constitution is a deci sive means for assessing silage or hay for a inter-grazing of fattenin g cattle; nutrient requirement norms are not practical in contrast to dairy cattle.
