“…According to Smeltzer et al (1986) population of bacteria were significantly larger in control than in compacted soil. The effect of compaction in reducing bacteria population had been also observed by Pupin et al (2009). In contrary, Shestak and Busse (2005) showed that the community of bacteria benefited from increased density, probably due to adaptation to the new soil conditions.…”

“…Microbial enzymes have essential functions in the soil and have been used to measure the influence of soil management and quality (Brzeziñska et al, 2001;Gajda, 2010;Riffaldi et al, 2003). Soil enzymes and microbial activities are sensitive biosensors of environmental changes (Jezierska-Tys et al, 2010;Pupin et al, 2009). Generally, compaction and mulch effects on soil microbial properties were studied separately.…”

Soil microbial activity as influenced by compaction and straw mulchingField study was performed on Haplic Luvisol soil to determine the effects of soil compaction and straw mulching on microbial parameters of soil under soybean. Treatments with different compaction were established on unmulched and mulched with straw soil. The effect of soil compaction and straw mulching on the total bacteria number and activities of dehydrogenases, protease, alkaline and acid phosphatases was studied. The results of study indicated the decrease of enzymes activities in strongly compacted soil and their increase in medium compacted soil as compared to no-compacted treatment. Mulch application caused stimulation of the bacteria total number and enzymatic activity in the soil under all compaction levels. Compaction and mulch effects were significant for all analyzed microbial parameters (P<0.001).

“…Physical and chemical properties have been extensively used to measure soil quality. However, these properties of soil change very slowly usually, and therefore significant changes may occur only over many years (Puglisi et al, 2006;Pupin et al, 2009). By contrast, soil biological and biochemical properties as activity of soil microorganisms and/or activity of enzymes are sensitive to sudden environmental changes, and providing sensitive information on changes in soil quality (Fr¹c et al, 2012;Green et al, 2007;Melero et al, 2010).…”

“…It is a good measure of organic matter turnover and biological activity in natural habitats and agricultural ecosystems (Green et al, 2007;Madejón et al, 2009). Microbial enzymes have essential functions in the soil and have been used to measure the soil quality and the influence of soil management (Bieliñska et al, 2008;Mohammadi, 2011;Pupin et al, 2009). Therefore, soil microbial biomass and enzymes activity have been suggested as potential indicators of soil quality because of their relationship to soil biology, and rapid response to changes originated by management and environmental factors (Fr¹c and Jezierska-Tys, 2011;Gajda, 2008Gajda, , 2010Madejón et al, 2009;Mohammadi, 2011).…”

The aim of this research was to evaluate changes in soil quality associated with the tillage system applied with chosen parameters of soil biological properties. The long-term field experiments were located at a private farm in Rogów (Zamooeć region, E Poland) on a silt soil and at the Experimental Station in Laskowice (Wrocław region, S-W Poland) on a sandy loam soil. Soil samples were collected from 0-15 and 15-30 cm layers. Winter wheat was grown under traditional, reduced and no-tillage systems. The analyses included estimations of microbial biomass C and N content, microbial respiration rate, activity of dehydrogenase and arylsulfatase, and fluorescein diacetate hydrolysis. After eight years the effects of tillage on both soils were clearly noticed. In general, the less disturbing tillage systems enhanced the increase of soil biological activity by 15-40%, on average, than conventional tillage system. The significant correlations between microbial biomass, and/or enzyme activities with total organic C content indicate that concentration of organic C in soil environment plays an extremely important role in enhancing the stabilization and activity of soil microorganisms, and protection of an extracellular enzymes. The studied parameters of soil biological activity showed their sensitivity to tillage applied and may be considered as an useful indicators of soil quality in monitoring all conditions alter soil environment.

“…Thus, the increase of total C stock in the layer of 0.10-0.20 m for the four evaluated minimum cultivation systems was possibly due to the lower soil disturbance by mechanical operations in this layer ( Figure 1C). In addition, the removal of chemical (limestone and gypsum applications) and physical (subsoiling) impediments, according to Arantes et al (2007) and Pupin et al (2009), respectively, favors root growth in subsurface and, consequently, C accumulation.…”

A B S T R A C TSoil carbon (C) stock determination can subsidize discussions on the continuity of an agricultural management. This study aimed to evaluate the stocks of total organic C (S TOC ) and labile C (S LC ), and the indices of C lability (CLI), C compartment (CCI) and C management (CMI), and correlate them with chemical and physical attributes of a Red Yellow Latosol (Oxisol) managed for 38 years with different tillage systems in a Cerrado region of Mato Grosso, Brazil. Disturbed and undisturbed soil samples were collected in three layers (0-0.05, 0.05-0.10 and 0.10-0.20 m). The CMI (CLI x CCI) showed higher S TOC possibly as the tillage depth decreased, because none of the tillage systems conserved S TOC and S LC in the layers of 0-0.05 and 0.05-0.10 m, compared with the Native Cerrado, i.e., soil C conservation only occurred in the layer of 0.10-0.20 m. Although the percentage of S LC in S TOC was lower, only S LC was correlated with soil chemical and physical attributes and, based on the multiple linear regression analysis, S LC was explained in 54% (R 2 ) by the cation exchange capacity and soil micropores. Therefore, for monitoring purposes, the S LCestimated can be useful to evaluate soil C storage.Estoques de carbono em Latossolo após trinta e oito anos sob diferentes sistemas de cultivo R E S U M OA determinação do estoque de carbono do solo pode subsidiar discussões sobre manejos agropecuários. Objetivou-se determinar os estoques de carbono orgânico total (E COT ) e lábil (E CL ) além dos índices de labilidade (IL), de compartimento (ICC) e de manejo do carbono (IMC) e correlacioná-los com atributos químicos e físicos de um Latossolo Vermelho-Amarelo manejado por 38 anos em diferentes sistemas de cultivo em bioma Cerrado. Coletaram-se amostras deformadas e indeformadas de solo nas camadas de 0-0,05; 0,05-0,10 e 0,10-0,20 m. Verificou-se que: o IMC (IL x ICC) acusou maior E COT à medida que diminuiu possivelmente a profundidade de revolvimento do solo pois nas camadas de 0-0,05 e 0,05-0,10 m nenhum sistema de cultivo conservou os E COT e E CL comparado ao Cerrado nativo, isto é, apenas de 0,10-0,20 m ocorreu conservação do carbono no solo; embora a porcentagem do E CL sobre o E COT fosse menor, apenas o E CL se correlacionou com atributos químicos e físicos do solo e, com base na análise de regressão linear múltipla, o E CL foi explicado em 54% (R 2 ) pela capacidade de troca de cátions e os microporos do solo. Portanto, para fins de monitoramento a E CL estimada pode ser útil para avaliar a estocagem de carbono no solo.
