Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed evaluate different pasture options relation their effect on soil stocks organic matter (SOM) humification. Pastures four beef cattle systems were assessed: intensive irrigated with stocking rate (IHS); dryland (DHS); moderate (DMS); degraded (DP). The under native forest was also evaluated carbon from 0-100 0-30 cm...
Advanced field methods of carbon (C) analysis should now be capable providing repetitive, sequential measurements for the evaluation spatial and temporal variation at a scale that was previously unfeasible. Some spectroscopy techniques, such as laser-induced breakdown (LIBS), have portable features may potentially lead to clean rapid alternative approaches this purpose. The goal study quantify C content soils with different textures high iron aluminum concentrations using LIBS. LIBS emission...
Soil carbon (C) determinations have been widely studied due to soil C sequestration that contributes the mitigation of greenhouse gas emissions and improves quality.
The correct choice of the calibration strategy method is a step that can ensure accuracy carbon determination in soils by laser-induced breakdown spectroscopy. In this paper, we evaluate and discuss intrinsic characteristics univariate multivariate strategies overcoming soil matrix effects their influence on magnitude prediction error values. matrix-matching with previous correction Al spectral interference C I line at 193.03 nm was best 13 models evaluated [root-mean-square...
The sugarcane processing generates by-product such as, bagasse ash and filter cake their proper disposal is of great environmental responsibility. Nowadays these by-products are being used for soil biofertilization without protocol. This study aimed to evaluate the applying a single kind in relation amount carbon (C) nitrogen (N) stability organic matter (SOM) through incubations varying time. bio-residues were applied at proportional dose 40 Mg ha−1 10 times periods defined. Elemental...
<p>The Integrated Crop-Livestock-Forest Systems (CLF) have been able to capture and store the carbon (C) in form of Soil Organic Matter (SOM), different regions Brazil, thereby contributing mitigate agricultural greenhouse gases emission. This is an eligible practice Low Carbon Emission Agriculture Plan currently has around 15 million hectares under use, a very positive important trend soil land use Brazil. SOM considered relevant indicator quality due its direct relationship...
