“…We found that the increase in SOC was related to soil aggregation, as more water-stable aggregates (!2 mm) were formed in compost-amended plots during the study (Whalen et al 2003;Jiao et al 2006). This suggests that the SOC accumulation in this soil was linked to C storage in macro-aggregates.…”

. 2008. Soil organic carbon and nitrogen pools as affected by compost applications to a sandy-loam soil in Quebec. Can. J. Soil Sci. 88: 443Á450. Compost contributes plant-available nutrients for crop production and adds partially decomposed carbon (C) to the soil organic carbon (SOC) pool. The effect of compost applications and other agricultural practices on SOC and total nitrogen (N) pools was determined in a sandy-loam Humic Gleysol at the Research Farm of McGill University, Ste-Anne-de-Bellevue, Quebec. Experimental plots with continuous silage corn (Zea mays L.) and silage corn-soybean (Glycine max L. Merr.) production were under conventional tillage (CT) or no-tillage (NT) management. Composted cattle manure was applied each spring at rates of 0, 5, 10 and 15 Mg (dry weight) ha(1 and supplemental NPK fertilizers were added to meet crop requirements. The C input from crop residues was affected by tillage, crop rotations and compost application, but differences in the SOC and total N pools were due to compost applications. After 5 yr, compost-amended plots gained 1.35 to 2.02 Mg C ha(1 yr (1 in the SOC pool and 0.18 to 0.24 Mg N ha(1 yr (1 in the total N pool, as compared with initial pool sizes when the experiment was initiated. These gains in SOC and total N were achieved with agronomic rates of compost and supplemental NPK fertilizers, selected to match the phosphorus requirements of silage corn. Such judicious use of compost has the potential to increase the SOC and total N pools in agroecosystems under annual crop production.

“…Neste estudo, as produtividades de grãos no sistema PD, especialmente no PD6, foram O aumento da produtividade no PD em relação ao PC decorre, provavelmente, da adição regular de palhada, que contribui para a melhoria da estrutura do solo favorecendo a aeração e a infiltração de água permitindo, assim, maior penetração das raízes (Jiao et al, 2006). Por outro lado, o uso contínuo do solo sob sistema PC, possibilita a formação de camadas compactadas, a redução da estabilidade dos agregados e o aparecimento, em maior número, de microporos, aumentando a propensão à perda de solo e aumento à resistência das raízes à penetração .…”

RESUMOO sistema de plantio direto é uma alternativa viável para o uso sustentável dos solos. O objetivo do presente trabalho foi avaliar a influência do sistema plantio direto com diferentes tempos de implantação e do plantio convencional sobre os atributos químicos e os estoques de C de um Latossolo VermelhoAmarelo do cerrado piauiense. Amostras de solo foram coletadas nas camadas de 0-5, 5-10, 10-20 e 20-40 cm em sistema de plantio convencional (PC) e plantio direto (PD) com 2 (PD2), 4 (PD4) e 6 (PD6) anos de implantação, além de uma área sob floresta nativa de cerrado (FNC). Foram determinados o pH em água, P extraível (Pext), bases trocáveis, Al, acidez potencial (H+Al), carbono orgânico total (COT) e carbono da biomassa microbiana (C mic ). A adoção do sistema plantio direto aumentou o pH, os teores de P e de bases trocáveis do solo, em comparação com o PC. Em relação ao PC, os estoques de COT e C mic aumentaram 34 e 99% no PD2, 47 e 92% no PD4 e 61 e 108% no PD6, respectivamente, na camada superficial de 0-20 cm. A implantação do sistema plantio direto melhora os atributos químicos e aumenta os estoques de carbono orgânico total e microbiano do solo e seu uso contínuo contribui para a qualidade do solo em áreas do cerrado piauiense.Palavras-chave: sistemas de preparo do solo, fertilidade do solo, carbono da biomassa microbiana, Glycine max L. Chemical attributes and carbon stocks in an Oxisolunder no-tillage in savannah of Piauí state ABSTRACT No-tillage adoption has been considered a viable alternative for sustainable soil use. This work aimed to evaluate the influence of no-tillage system with different times of adoption and conventional tillage on chemical attributes and carbon stocks in an Oxisol of the savannah of Piauí in Northeastern Brazil. Soil samples in the 0-5, 5-10, 10-20 and 20-40 cm layers were collected in conventional tillage (CT) no-tillage (NT) with 2 (NT2), 4 (NT4) and 6 (NT6) years of adoption and native forest (NF). The following chemical properties were evaluated: pH, extractable P, exchangeable cations, Al, potential acidity (H+Al), total organic carbon (TOC) and microbial biomass carbon (C mic ). NT adoption increased pH, extractable P and exchangeable cations contents. Compared to conventional tillage, TOC and C mic stocks increased 34 and 99% (NT2), 47 and 92% (NT4) and 61 and 108% (NT6), respectively, in the superficial layer (0-20 cm). No-tillage adoption improves chemical attributes and increases total organic carbon and microbial carbon and its continuous use contributes to soil quality in savannah soils of Piaui state.

“…Positive effects of green manure and FYM application on aggregate stability have been reported in a number of studies Singh et al, 2007). The proportion of large macro aggregates within the total soil aggregates is the most important fraction to evaluate the effect of management practices on soil aggregation, because it exerts a strong influence on the mean weight diameter (MWD), a comprehensive index for evaluating soil aggregation (Jiao et al, 2006). Again, higher crop residue-C might have an effect on aggregate stability as plant roots are important binding agents at the scale of macro aggregates (Six et al, 2004).…”
