Abstract:

Soil management in vineyard inter-rows varies depending on pedoclimatic local conditions, management philosophy of wine growers or traditional established practices. In the past, frequent tillage was the standard practice in wine-growing regions. Various management practices in vineyard inter-rows such as permanent vegetation cover, alternating tillage or frequent tillage result in different effects on above and belowground ecosystem service provisions. This study was embedded in the European BiodivERsA project VineDivers: “Biodiversity based ecosystem services in vineyards: analysing interlinkages between plants, pollinators, soil biota and soil erosion across Europe”. 120 core samples were taken in 15 vineyard inter-rows in the top 10 cm soil to analyse the effect of soil management systems on root parameters of the inter-row vegetation in Romanian vineyards. Roots were extracted from soil samples by washing them out and analysed concerning the most important root parameters: total root length density, total root surface area density, average root diameter and root mass density. Analysis was done in the laboratory with the image analysis system WinRHIZO. From the examined vineyards 7 vineyards were tilled frequently, 3 were treated with an alternating tillage system and on 5 vineyards a permanent vegetation cover was established. Vineyards managed with permanent vegetation cover showed a significantly higher total root length density, higher total surface area density and higher root dry mass density than vineyards managed with alternating tillage or frequent tillage. Furthermore, total organic carbon content was the highest in vineyards with permanent vegetation cover, which in turn can contribute to carbon sequestration, prevention of soil erosion, etc. The choice of soil management therefore is a key management tool to affect plant root parameter and further contribution to ecosystem services.
