Effects of Organic Mulches on the Soil Temperature, Humidity and CO2 Emissions

Abstract

A large portion of the world wine production is located in regions suffering -or expected to suffer -from desertification. These agricultural soils, in addition to being highly unstructured, have very low levels of organic matter (<1%). This is aggravated by an abusive tillage of the plots, which implies that the maintenance of these soils depends entirely on the addition of chemical products such as fertilizers and herbicides. This situation, in turn, leads to physiological imbalances in the vine that result in deficiencies in the quality of the grape.
