In South Brazil, grapevines (Vitis vinifera L.) have been grown in acid sandy soils, increasing phosphorus (P) need for fertilization. However, current fertilizer guidelines for growers are based on Vitis labrusca grown in clay soils. Therefore, there is a clear need to provide new recommendations on fertilization in vineyards. This study aimed to: (i) establish critical levels (CL) for P in the soil and grape leaves at flowering and veraison growth stages; and (ii) propose P maximum technical efficiency (MTE) rates for white and red grapevines grown in sandy soils based on a Bayesian approach. The study was carried out in sandy soil in South Brazil, with six P fertilization rates. |
