Full textThe objective of this study was to quantify the changes of the total carbon (C) and total nitrogen (N) stock, and the variation of the C pool’s in monthly soil samples, and the C balance and C sequestration rates provoked by the soil tillage systems. The soil samples were accomplished in a long term experiment implanted in 1988, in the experimental station of Fundação ABC located in Ponta Grossa city, Center-South area of the Paraná State. The soil tillage systems were comprised: a) Conventional Tillage (CT); b) Minimum Tillage (MT); c) No-tillage with chisel plow (NTCP) each three years; and d) No-tillage – Continuous (NTC). Soil samples for each treatments were obtained by digging 3 profiles of 20-cm x 50-cm (surface area) x 50-cm deep for each replicate, and collected from three depths (0,0- to 2.5- cm, 2.5- to 5-cm, 5- to 10-cm). In the samples collected in October of 2003, May of 2004 and November of 2004, the total organic carbon (TOC) and the total nitrogen in all of the depths was measured. The particle size fractionation was accomplished, separating the soil in fractions in the size of 2000 - 210 Wm, 210 - 53 Wm and <53 Wm. In all these fractions TOC was determined. The treatments had significant effects on TOC and TN contents and pools. The total C and N stock in NTC was superior to the other systems demonstrating larger maintenance of C in the soil. The larger concentration of C was observed in the 210 to 53 Wm particle size fraction in the NTC. In the 2000 - 210 Wm fraction of the 0,0-2,5 cm layer were observed larger changes in the C stock due to the management systems in the samples at all long year. The greatest change was accomplished to CT. In NTP, the stock of C was larger in all soil samples, indicating that the maintenance of the cultural residues in the associated surface protection of the aggregates allows larger accumulation of C. Although the C stock in the particle size fraction <53 Wm not to present significant differences among the management systems, and was observed the C migration of the coarse fractions (210-53 and 2000-210 Wm) to the recalcitrant particle size fraction, indicating a continuous C flow. The C balance model adjusted for the local conditions revealed that the oxidation rate acted by K2 is inferior to the simulations accomplished by other authors, demonstrating the importance of the local conditions. With this model, the minimum amount of crop residues to maintain NTC system in steady-state was 8,05 Mg ha-1 year-1 while in the PC treatment it won't be possible to reach the balance with the amount of crop residues placed in this long term experiment, being a deficient system.
RESUMO Este estudo teve por objetivo quantificar as alterações provocadas pela adoção de sistemas de manejo do solo sobre o estoque total de carbono (C) e nitrogênio (N), a variação do estoque do C nas épocas de coleta, o balanço de C e as taxas de seqüestro de C. As coletas do solo foram realizadas em um experimento de longa duração, implantado em 1988, na estação experimental da Fundação ABC em Ponta Grossa, Meso Região Centro-Oriental do Estado do Paraná. Os sistemas de manejo do solo foram avaliados: a) Preparo convencional (PC), Preparo mínimo (PM), plantio direto escarificado (PDE) e plantio direto permanente (PDP). As amostras foram coletadas em 12 épocas com intervalos mensais e nas profundidades de 0,0-2,5; 2,5-5,0 e 5,0-10 cm de profundidade. As amostras deformadas foram coletadas em mini-trincheiras nas camadas de 0,0-2,5 e 2,5-5,0 cm e na camada de 5,0- 10,0 cm com o auxílio do trado. Nas amostras coletadas em outubro de 2003, maio de 2004 e novembro de 2004 foi determinado o carbono orgânico total (COT) e o nitrogênio total (NT) em todas as profundidades amostradas. Nas amostras coletadas mensalmente foi realizado o fracionamento granulométrico da matéria orgânica, separando o solo em frações no tamanho 2000 – 210 Wm, 210 – 53 Wm e < 53 Wm. Em todas estas frações foi determinado o COT. O estoque total de C e N no PDP foi superior aos demais sistemas de manejo demonstrando maior manutenção do C no solo. O estoque de C nas frações granulométricas apresentaram diferenças significativas entre as camadas amostradas, observando-se maior concentração de C na fração 210 a 53 Wm do PDP. Na fração 2000 – 210 Wm da camada de 0,0-2,5 cm observaram-se maior alteração no estoque de C devido aos sistemas de manejo durante as épocas de coleta, sendo a maior amplitude de variação atribuída ao PC. No PDP, o estoque de C foi maior em todas as épocas de coleta indicando que a manutenção dos resíduos culturais na superfície associada à proteção dos agregados permite maior acúmulo de C. Embora o estoque de C na fração < 53 Wm não apresentar diferenças significativas entre os sistemas de manejo, observou-se uma migração do C das frações mais grosseiras (210-53 e 2000-210 Wm) para esta fração mais recalcitrante, indicando um fluxo contínuo de C. O modelo de balanço de C proposto por Henin e Dupuis (1945) e ajustado para as condições locais revelou que a taxa de oxidação representada pelo K2 é inferior às simulações realizadas por outros autores, demonstrando a importância das condições locais. Com este modelo, a quantidade mínima de resíduos culturais para manter sistema PDP em equilíbrio foi de 8,05 Mg ha-1 ano-1 enquanto no PC não será possível atingir o equilíbrio com a quantidade de resíduos culturais aportada, sendo um sistema deficitário.

Full textThe agroecological transition targets triple agronomic, ecological, and societal performance of farms. Some new agricultural practices had emerged to develop a new cropping system to respond to these constraints. Legumes constitute an interesting alternative. Indeed, legumes are advantageous for soils due to their symbiotic relationship with nitrogen-fixing bacteria. The presence of compatible rhizobia combined to nitrogen-limited conditions promotes symbiosis which is the most efficient way for legumes to acquire more nitrogen. Compared with non-nodulated plants, symbiosis provides a competitive advantage by increasing soil nitrogen pool. However, some grain legumes, notably winter pea, are rarely studied, especially in the Normandy region where no reference has been published for this crop. The objective of this study is to compare two crop successions for a period of two years (winter pea-wheat and rapeseed-wheat), in order to assess the effect of replacing rapeseed by winter pea at the head of the rotation .We evaluated the effect of these two crops (winter pea vs rapeseed) on the biological state of the soil and nitrogen fluxes at different spatio-temporal scales. The results showed a significant spatio-temporal effect on the response of soil microbial communities and highlighted the importance of the pedoclimatic context in determining the abundance and activity of soil microbial communities. A positive effect of winter pea has been demonstrated on the availability of mineral nitrogen during the crop cycle and for following crops (wheat and barley). The supply of nitrogen to the soil is linked to the rhizodeposition of nitrogen via plants roots and the degradation of crop residues after harvest. Our results showed that winter pea exhibited the greatest amount of nitrogen rhizodeposition. However, rhizodeposition did not have a significant impact on rhizospheric microbial communities. Contrary to these observations, the degradation of crop residues significantly modified the composition of bacterial communities linked to their initial biochemical composition. Crop succession including winter pea enriched the soil with mineral nitrogen but simulation with STICS software revealed a nitrogen leaching around of 23 kg N. ha-1 during the cropping cycle. These findings underline the importance of adapting an adequate crop management system, including winter pea, to limit nitrogen losses. The results showed also that wheat yields after winter pea without the use of nitrogen fertilizers were equivalent to those obtained after rapeseed. However, rapeseed required significant nitrogen fertilization. Including winter pea in crop rotation in Normandy region may be a key to enhance productivity, to respond to the challenges of agroecological transition, regional protein autonomy, and to reduce environmental and economic costs, by reducing notably, the costs of fertilizers production and uses
