Anji Perry of J. Lohr Vineyards shares her practical approach to vineyard nutrition, emphasizing sustainability and precision. She outlines five core factors she uses to guide nutrient decisions: soil quality, water quality, YAN (Yeast Assimilable Nitrogen), leaf analysis, and visual symptoms. Anji discusses the importance of nitrogen and potassium in vine health and wine quality, and how site-specific strategies and minimal fertilization can lead to better outcomes. She also highlights the promise of precision viticulture and the need for updated nutrient guidelines to support long-term vineyard productivity and sustainability.
