“…BC provided favoring conditions to the neo-formation of ferromagnetic minerals, since soil is subjected to high temperatures during the burning of sugarcane, in preharvest. Mineral neo-formation after burning has also been reported by other authors in natural and cropped environments (TORRENT; BARRÓN, 2010;LIU et al, 2012;BAHIA et al, 2015). Greater magnetic values may refer to presence of mineral coal (biochar) in soil, which affect electrochemical changes (SPOKAS et al, 2015).…”

-Sugarcane management practices (unburned cane -UC and burned cane -BC) interfere with dynamics of soil magnetic properties. This study focused on determining the potential of magnetic susceptibility as soil quality indicator in areas under sugarcane cultivation. The experiment area is on the limit between basalt from São Bento Group, Serra Geral Formation, and sandstone from Bauru Group -Adamantina Formation. Twenty soil samples were collected from two management areas (burned and unburned sugarcane prior to harvest) at a depth range of 0.0-0.2 m. Local soil was classified as eutroferric Red Latosol (Oxisol), with highly clayey texture. Chemical and physical properties, CO 2 emissions and magnetic susceptibility (MS) in air-dried fine earth (MS ADFE ), total sand fraction (MS TS ) and clay fraction (MS CF ). The magnetic signature from MS was effective in identifying changes of physical, chemical and mineralogical traits in Latosols under burned and unburned sugarcane crop. The information provided here can guide further studies on the genesis of minerals with magnetic expression in environments and exposed to fire burning.Keywords: Magnetic signature.

SUSCETIBILIDADE MAGNÉTICA COMO INDICADOR DE QUALIDADE DO SOLO EM ÁREAS SOB CULTIVO DE CANA-DE-AÇÚCARRESUMO -As práticas de manejo utilizadas na cultura da cana-de-açúcar (cana crua -CC e cana queimada -CQ) interferem na dinâmica dos atributos e expressão magnética do solo. Foi estudado o potencial da suscetibilidade magnética como indicador de qualidade do solo em áreas sob cultivo de cana-de-açúcar. O experimento localiza-se em uma área limítrofe de material de origem, entre o Basalto do Grupo São Bento, Formação Serra Geral, e o Arenito do Grupo Bauru, Formação Adamantina. Foram coletadas 20 amostras de solo em dois sistemas de manejo (com e sem queima da cana-de-açúcar para colheita) na profundidade de 0,0-0,2 m. O solo foi classificado como Latossolo Vermelho Eutroférrico, textura muito argilosa. Foram avaliados os atributos químicos, físicos, emissão de CO 2 e a suscetibilidade magnética (SM) do solo na terra fina seca ao ar (SM TFSA ), fração total sand (SM AT ) e fração argila (SM ARG ). A assinatura magnética expressa pela suscetibilidade magnética foi eficaz na identificação de mudanças nas características físicas, químicas e mineralógicas de Latossolos sob sistemas de colheita da cana-de-açúcar com e sem queima. As informações geradas neste trabalho podem balizar futuros estudos sobre a gênese de minerais com expressão magnética em ambientes e expostos a presença de fogo.Palavras -chave: Assinatura magnética.

Climate change is the one of the most emerging problem of today’s world. It is the most potent threat to the existence of mankind. These sudden abrupt changes in the climate are affecting all the crops to a great extent. High concentrations of CO2 are one of the leading reasons contributing to climate change due to the increasing level of green-house gases. The elevation in CO2 level is hampering crop production and productivity of different crops by causing effect on different physiological attributes. Unlike other crops, in sugarcane, several beneficial effects have been detected such as escalation in biomass, photosynthesis, leaf area, stalk juice volume, leaf dry weight and stem dry weight under such condition. Sugarcane crop is known to be one among those crops that is able to cope up with the increasing level of CO2 due to four natural endowments it possesses. Very low carbon dioxide compensation point and unique property of sequestering carbon in form of phytolith or planstone is some of the important natural endowment with respect to the rising CO2 concentration in atmosphere. Here, we have discussed the influence of atmospheric rising CO2 concentration on sugarcane crop.

“…However, to our knowledge, no studies can be found in the literature comparing soil CO 2 emission under the cultivation of different sugarcane cultivars. In fact, the existing studies are limited to assess soil CO 2 emissions in areas with a single cultivar (Luca et al 2008;Panosso et al 2009;Figueiredo et al 2010;Teixeira et al 2011;Bicalho et al 2014;Bahia et al 2015).…”

Short-Term Soil CO2 Emission and Soil Attributes Under Contrasting Sugarcane Cultivars

et al. 2018

Agriculture is a great emission source of CO 2 into the atmosphere, contributing significantly to the greenhouse effect. Considering the hypothesis that there are differences in soil carbon dynamics due to the distinct physiological and morphological characteristics of sugarcane cultivars, the aim of this study was to characterize the short-term soil CO 2 emission associated with soil attributes in agricultural areas under cultivation of five sugarcane cultivars. The experiment was conducted in an area of high-clay Oxisol (Hapludox, USDA Soil Taxonomy) located at the Cerrado biome, Midwestern region of Brazil. Over the course of 20 days, ten measurements of soil CO 2 emission (FCO 2), soil temperature (Ts), and soil moisture (Ms) were carried out. Subsequently, soil samples were collected at a depth of 0-0.20 m to determine soil physical and chemical attributes. In timescale, FCO 2 , Ts, and Ms varied depending on the amount of straw produced by each cultivar. The cultivars RB935608, RB935744, and SP832847 induced a higher soil CO 2 emission since they are associated with controlling factors of the primary CO 2 production process (higher organic matter content and lower C/N ratio in the soil). Thus, strategies to reduce greenhouse gas emissions in agriculture, such as the choice of sugarcane cultivars that provide lower soil CO 2 emissions, are essential to mitigate important environmental issues such as the global warming.
