Assessing the carbon stock of cultivated pastures in Rondônia, southwestern Brazilian Amazon

Anais da Academia Brasileira de Ciências, 2022
Cattle ranching is the primary land-use of deforested areas in the Brazilian Amazon. Deforestation precedes pasture establishment, implying tremendous amounts of greenhouse gas emissions caused by carbon stock losses. Despite several studies addressing carbon storage in forests, there is a lack of data regarding cultivated pastures.

Assessment of different infiltration equations for cultivated and pasture land

INTERNATIONAL JOURNAL OF AGRICULTURAL ENGINEERING, 2020
The measure of infiltration of water into the soil is an important indication concerning: the efficiency of irrigation and drainage optimizing the availability of the water for plant improving the yield of the crop and minimizing the erosion. By knowing proper infiltration characteristics and intake capacity of soil, deep percolation losses can be ...

Spatial variability of the horizontal structure and production of biomass in Massai grass in an agropastoral system

Revista Verde de Agroecologia e Desenvolvimento Sustentável, 2021
In Brazil, 60% to 80% of cultivated pastures show some degradation level. Thus, the objective was to evaluate the variability of the horizontal structure and biomass of Massai grass in an agropastoral system as a diagnosis of degraded pasture.
