Since sugarcane areas have increased rapidly in Brazil, the contribution of production, and, especially, harvest system to greenhouse gas emissions country is an issue national concern. Here we analyze some data characterizing various activities two mills during period 2006-2007 and quantify carbon footprint sugar production.According our calculations, 241 kg dioxide equivalent were released atmosphere per a ton produced (2406 hectare cropped area, 26.5 processed). The major part total...
The soil CO2 emission has high spatial variability because it depends strongly on properties. purpose of this study was to (i) characterize the respiration and related properties, (ii) evaluate accuracy results ordinary kriging method sequential Gaussian simulation, (iii) uncertainty in predicting other properties using simulations. conducted a sugarcane area, regular sampling grid with 141 points, where emission, temperature, air-filled pore space, organic matter bulk density were...
Abstract New management strategies should be identified to increase the potential of bioenergy crops minimize climate change. This study quantified impact sugarcane ( Saccharum spp.) harvest systems, straw and soil on carbon dioxide CO 2 ) fluxes prior crop replanting carried out February 2010 in southern Brazil. The studied was classified as Haplustult USDA Soil Taxonomy). Three systems were considered: burned BH green with maintained GH SM or removed from SR surface. Our hypothesis is that...
Abstract The management adopted in the establishment and replanting of sugarcane fields, with conventional tillage followed by fallow, is one main causes soil quality degradation. In this context, index (SQI) an important tool to guide use more sustainable practices management. This study aimed monitor effect different cover crops association systems on yield based key indicators SQI developed using Soil Management Assessment Framework (SMAF). experiment was carried out a expansion area...
Global climate change is closely tied to CO2 emissions, and implementing conservation-agricultural systems can help mitigate emissions in the Amazon. By maintaining forest cover integrating sustainable agricultural practices pasture, these preserve carbon stocks Amazon soils. In addition, improve soil health, microclimate regulation, promote region. This study aimed evaluate emission dynamics its relationship with attributes under different uses The experiment consisted of four treatments...
Abstract Soil CO 2 emission is an important part of the terrestrial carbon cycling and influenced by several factors, such as type distribution vegetation. In this work we evaluated spatial variability soil in ecosystems maritime Antarctica, under two contrasting vegetation covers: 1) grass areas Deschampsia antarctica Desv., 2) moss carpets Sanionia uncinata (Hedw.) Loeske. Highest mean was obtained for (4.13 μmol m -2 s -1 ) developed on organic-rich with a strong penguin influence. The...
O solo é um dos principais compartimentos de carbono no ecossistema terrestre, capaz armazenar quantidades expressivas desse elemento e, portanto, a compreensão fatores que contribuem para as perdas CO2 em solos agrícolas fundamental determinar estratégias redução das emissões gás e ajudar mitigar o efeito estufa. objetivo deste estudo foi investigar do preparo da deposição resíduos cultura cana-de-açúcar na emissão CO2, temperatura umidade solo, durante reforma canavial, ao longo período 15...
A compreensão do potencial agrícola de um solo muitas vezes é com base apenas na interpretação por meio análises univariadas, podendo elevar a dimensão dos problemas no momento escolher o manejo adequado ao solo. Dessa forma, análise multivariada surge como alternativa, pois ela conjunto procedimentos que visa agrupar e discriminar grupos indivíduos. Também, serve instrumento seleção variáveis, medida em aquelas maior peso construção primeiros componentes principais são as possíveis melhor...
Neste trabalho, foi determinada a estrutura da variabilidade espacial emissão de CO2, temperatura e umidade solos desprovidos vegetação em duas localidades sob cultivo cana-de-açúcar, sistemas manejos cana crua queimada, no nordeste do Estado São Paulo. A CO2 solo foram registradas utilizando-se câmara fluxo portátil sensor sistema LI-6400. avaliada utilizando TDR. maior observada local manejo com valor médio 2,05 μmol m-2 s-1, porém dependência na encontrada somente área crua. Os mapas...
