A Spanish vineyard has gone more than 20 years without irrigation or pesticides; its cover-cropped topsoil now has over twice the organic matter of nearby tilled soil

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.
