Description

Permanent grass cover under grape vines protects the soil surface against erosion and compaction - and provides better conditions for traffic within the rows during mechanised field operations

Permanent grass cover under grape vines protects the soil surface against erosion and compaction - and provides better conditions for traffic within the rows during mechanised field operations. Grass can be sown using a mixture of grass and legume species - white clover, red clover, tall fescue are the most widely used - or it can be allowed to germinate naturally after stopping regular tillage applications. For the maintenance of grass cover and to avoid the disadvantages of tall grass it must be regularly cut. The height of the grass is most important directly below the grape rows. Grass clippings are a great source of nitrogen and break down quickly, so it can be used as mulch. But winegrowers/farmers who deal with animal husbandry too, prefer to use grass clippings as fodder. Herbicides are often used to control the grass in narrow strips underneath the grape rows.
One benefit of the grass cover is the good soil protection on slopes - where vineyards are often established due to better exposure to the sun. In addition, it gives better traction for machines, especially on steep gradients: this is appreciated by land users. Permanent grass cover makes for a cooler and more humid microclimate in the vineyard, but this means a greater risk of fungal diseases and loss of moisture due to the transpiration demand of the grass.
