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.
