Abstract

The soil stores significant amounts of carbon in its structures, therefore it is necessary to understand the factors that can generate losses of this essential element for living beings. Agricultural mechanization is one of the main factors that affect soil carbon emissions, through soil tillage management, which can be: Conventional tillage (PC), Reduced tillage (PR), and Direct planting (PD). These managements influence greater or lesser soil preservation depending on the type carried out. The objective of this project is to evaluate the fuel consumption of an agricultural tractor equipped with radial and diagonal tires in conventional and reduced soil tillage, and to verify the emission of C02 from the soil in relation to each management. The experimental area will consist of two plots, each receiving one of the soil tillage: conventional tillage and reduced tillage. The hourly and operational fuel consumption, the slipping of the front and rear wheels and the kinematic progress of the tractor will be evaluated when the preparations are carried out. FCO2, temperature and soil humidity will be evaluated over a total period of 20 days. It is expected that the results will make it possible to evaluate the potential reduction in CO2 emissions from the soil due to the use of reduced tillage and reduced fuel consumption with the use of radial tires.
