Two-Decade Study Shows Organic Farming Doubles Soil Organic Matter in Spanish Vineyards

Vineyard skips irrigation and pesticides for 20 years; organic matter doubles

A Spanish vineyard study revealed significant soil health improvements over two decades. Long-term vegetation cover doubled topsoil organic matter compared to tilled areas. This practice enhanced soil porosity and biological activity in dry conditions. The findings suggest reduced soil disturbance benefits water-limited vineyards. Allowing plants to remain strengthens soil function under challenging climates.
