Abstract

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

Highlights

  • The traditional cultivation of the vine all around the world has been reconverted and more winemakers have decided to return to the origins, taking care of their vines as their predecessors, without adding additives or pesticides and promoting an ecological agriculture

  • These agricultural soils, in addition to being highly unstructured, have very low levels of organic matter (

  • A similar trend occurred with mean soil temperature (Figure 2)

Summary

Introduction

The traditional cultivation of the vine all around the world has been reconverted and more winemakers have decided to return to the origins, taking care of their vines as their predecessors, without adding additives or pesticides and promoting an ecological agriculture. The impact of soil mulching on crop yields and greenhouse gas emissions was affected by temperature, water input amount, cultivation practice and nitrogen application rate. In this sense, decreases [13,14] or no changes [15,16] in soil greenhouse gas emissions by straw mulch were observed under some cropping systems, soil types, and nitrogen fertilizer levels. It is imperative to know the processes that control soil environments under various mulching conditions and the effects of mulching materials on crop yield, productivity and water use efficiency In this context, the developed research aimed at studying the effects of different mulches on thermal fluctuations and humidity in the soil as well as their role in the CO2 uptake.
