Vineyard sandy acid soils from South Brazil have experienced heavy metal contamination due to replacement of copper (Cu)-based by zinc (Zn)-based products to control foliar diseases. Thus, we evaluate physiological and nutritional status of black oat (Avena strigosa Schreb.), a common interrow crop in vineyards from this region. Soil was collected in a natural field from Santana do Livramento, in...
The application of fungicides containing Cu and Zn in vineyards can lead to accumulation of these metals at toxic levels. The successive cultivation of maize in these areas can be an interesting alternative to alleviate the toxic levels of these metals in the soil. This greenhouse study aimed to assess whether the increase in Zn concentration in vineyard soils with high Cu concentration from Southern...
