“…Neste processo os microrganismos obtêm energia por meio da oxidação de carboidratos, com consequente produção de água e CO 2 (Six et al, 2006). Além disso, o preparo intensivo do solo pode reduzir a cobertura vegetal que protege o solo, expondo-o à radiação solar o que resulta, na elevação da temperatura (Licht & Al-Kaisi, 2005) e redução da umidade do solo (Schwartz et al, 2010), favorecendo a atividade microbiana.…”

R E S U M OO preparo mecânico do solo é uma das práticas agrícolas que contribuem para o aumento da perda de carbono via emissão de CO 2 do solo (FCO 2 ). Com este trabalho objetivou-se investigar o efeito de três sistemas de preparo do solo na FCO 2 , temperatura e umidade do solo em área de reforma da cultura de cana-de-açúcar. A área experimental foi constituída de três parcelas, cada uma recebendo um dos preparos do solo: preparo convencional (PC), subsolagem convencional (SC) e subsolagem localizada (SL). A FCO 2 , temperatura e a umidade do solo foram avaliadas durante o período total de 17 dias. A FCO 2 foi maior no preparo PC (0,75 g CO 2 m -2 h -1 ). A temperatura do solo não diferiu (p > 0,05) entre as subsolagens: SL (26,2 ºC) e SC (25,9 ºC). A umidade do solo foi maior na SL (24%), seguida pela SC (21,8%) e preparo PC (18,3%). Apenas no preparo PC foi observada correlação significativa (r = -0,71; p < 0,05) entre FCO 2 e a temperatura do solo. O preparo PC apresentou emissão total (2.864,3 kg CO 2 ha -1 ), superior às emissões nas subsolagens: SC (1.970,9 kg CO 2 ha -1 ) e SL (1.707,7 kg CO 2 ha -1 ). A conversão do sistema de preparo PC para a SL diminuiu as emissões de CO 2 do solo, reduzindo a contribuição da agricultura para o aumento dos gases de efeito estufa na atmosfera.Soil tillage and emission of CO 2 , soil temperature and soil moisture in a sugarcane area A B S T R A C TSoil tillage is one of the agricultural practices that may contribute to increase the loss of carbon through emission of CO 2 (FCO 2 ). The aim of this study was to investigate the effect of three soil tillage systems on FCO 2 , soil temperature and soil moisture in a sugarcane area under reform. The experimental area consisted of three tillage plots: conventional tillage (CT), conventional subsoiling (CS), and localized subsoiling (LS). FCO 2 , soil temperature and soil moisture were measured over a period of 17 days. FCO 2 showed the highest value in CT (0.75 g CO 2 m -2 h -1 ). Soil temperature presented no significant difference (p > 0.05) between LS (26.2 °C) and CS (25.9 °C). Soil moisture was higher in LS (24%), followed by CS (21.8%) and CT (18.3%). A significant correlation (r= -0.71; p < 0.05) between FCO 2 and soil temperature was observed only in CT. The conventional tillage presented a total emission (2,864.3 kg CO 2 ha -1 ) higher than the emissions observed in CS (1,970.9 kg CO 2 ha -1 ) and LS (1,707.7 kg CO 2 ha -1 ). The conversion from CT to LS decreased soil CO 2 emissions, reducing the contribution of agriculture in increasing the concentration of greenhouse gases in the atmosphere.

“…Most of the studies published up to now deal with the comparison between conventional tillage and no-tillage. Licht and Al-Kaisi [45] observed that penetration resistance under no-tillage was generally greater than that of chisel plough, especially in the top 20 cm soil depth. Nevertheless, their results show a high variability in penetration resistance among different tillage systems, which is in accordance with our results.…”

“…The effect of tillage on soil status has frequently been investigated in agricultural environments (e.g. [11,19,45]), whereas very few studies have been carried out in forest conditions (but see [10,20,38]). Moreover, studies investigating the effect of tillage on bulk density and water infiltration have led to contradictory and inconclusive results due to variability of soils different researchers worked on [29].…”

Therefore, quantifying the effects of tillage systems on soil moisture, temperature, and compaction can help explain some of the differences in plant growth and development in different tillage systems [45]. The influence of soil loosening on plant development has been widely studied on crop plants (e.g.…”

Effects of soil mechanical treatments combined with bramble and bracken control on the restoration of degraded understory in an ancient beech forest

et al. 2007

-This paper describes the ground floor vegetation that developed four years after tillage implements in an ancient beech forest in central Belgium. The purpose of this study was twofold: (1) to explore whether tillage has a lasting effect on soil compaction and soil moisture as well as on vegetation characteristics; and (2) to analyse whether two distinct tillage treatments (rotary plough vs. disc plough), combined with vegetation control when necessary, have the same effect on soil compaction, soil moisture and plant establishment. Of the 29 species recorded, 15 showed a significant recovery after soil loosening in the studied forest area. Interestingly, different tillage treatments did not have the same influence on plant establishment. Treatment effects on soil structure and/or moisture status can be considered as causing the observed growth response.ancient forest species / forest understory / soil compaction / soil tillage / soil loosening technique Résumé -Effets de traitements mécaniques du sol combinés à un contrôle de la ronce et de la fougère aigle sur la restauration d'un sous-bois dégradé dans une ancienne hêtraie. Cette étude décrit la flore herbacée qui s'est développée quatre années après la mise en place d'expériences de traitement mécanique du sol dans une ancienne hêtraie dans le centre de la Belgique. Les objectifs furent : (1) explorer si le traitement mécanique du sol a un effet durable sur la compaction et l'humidité du sol et sur les caractéristiques de la végétation ; et (2) analyser si deux traitements effectués avec des machines différentes (crabe et fraise rotative), combinés à un contrôle de la végétation si nécessaire, ont le même effet sur la compaction et l'humidité du sol et sur l'établissement des plantes. Parmi les 29 espèces inventoriées, 15 ont montré un développement significatif suite au labour du sol dans les zones expérimentales étudiées. Il est intéressant de constater que les différents traitements n'ont pas eu la même influence sur l'établissement des espèces végétales. L'effet des traitements sur la structure et/ou l'humidité du sol peut être considéré comme étant la cause de la réponse végétale observée.espèces des forêts anciennes / sous-bois / compaction du sol / labour du sol / technique d'ameublissement du sol

In organic cropping systems, air-propelled abrasive grits can be used to control in-row weeds. If the applied abrasive grit is an approved organic fertilizer, these applications may serve a dual purpose of weed control and crop fertility. Laboratory soil incubations examined the N mineralization rates of several grit types with differing C/N ratios (Agra Grit [crushed walnut shells, 170:1], corncob grit [91:1], Sustane [composted turkey litter, 5.0:1], Phytaboost Plant Food [crushed and pelletized soybean meal, 5.0:1]). A greenhouse study determined plant wheat (Triticum aestivum L.), kale (Brassica napus pabluaria DC), and velvetleaf (Abutilon theophrasti Medik.) growth response in soils amended with these grits. The N mineralization rates varied by grit type, soil, and application rate. The N mineralized from Phytaboost within 56 d was similar among the amounts of N a whereas the amount of N mineralized from Sustane was inversely related to the amount of N applied. Agra Grit and corncob grit immobilized soil N due to their high C/N ratios. In soils amended with Sustane, plant height and biomass were 15-43% and 34-83% greater than for plants grown in soils with Agra Grit, corncob grit, and the nontreated soil. Applications of organic fertilizer as air-propelled grit may improve crop growth; however, if weed control is imperfect, these grits may increase weed growth. Grits with high C/N ratios may immobilize soil available N but not affect plant growth. Abbreviations: DAP, days after planting.
