Grape quality starts at the roots

摘要: Vine productivity and grape quality are closely related not only to external factor, such as climatic conditions canopy management, but also the relationships formed between roots dynamic variable properties of soil. Root density distribution affected by rootstock genotype, soil texture, water nutrient availability, aeration. Vineyard practices, like ploughing or manuring composting, can partially modified characteristics that hinder correct root development. In order establish appropriate vineyard management practices focus on health system, it is crucial understand their rhythms growth absorption. It important remember development cyclical, with annual peaks which synchronous above-ground fruit ripening. The periodic new structures aimed both at increasing overall exploration range replacing senescent structures.

This seasonal should be taken into account for fertilizer application.
