“…In a review of long term experiments in Uruguay, Garcia Préchac et al [80] reported a six-fold erosion reduction under NT compared to CT conditions. Soil losses were similar between continuous pastures and crop rotations that incorporated pasture suggesting the efficacy of pastures to reduce soil erosion was evident even in short-term rotations.…”

“…Estas melhorias ocorrem pela presença de palha e raízes da pastagem, que contribuem para o aumento nos teores de carbono do solo (LOSS et al, 2011) e maior atividade da macrofauna do solo (MARCHÃO et al, 2007). Outros benefícios no consórcio é a redução de plantas daninhas FONSECA et al, 2007;BORGHI et al, 2008;PACHECO et al, 2009); e o incremento na produtividade de lavouras subsequentes (ALBUQUERQUE; SANGOI; ENDER, 2001;GARCÍA-PRÉCHAC et al, 2004;ARGENTON et al, 2005;BARDUCCI et al, 2009). …”

Efeito da época e sistema de semeadura da Brachiaria brizantha em consórcio com o milho, sobre os componentes de produção e propriedades físicas do solo Effect of time of sowing and system Brachiaria brizantha intercropped with maize on yield components and soil physical properties AbstractThe objective of this study was to evaluate the development of Brachiaria brizantha-MG-4; sown in two seasons and two seeding systems in space between two rows, and to evaluate the effect of intercropping on maize yield, as well as evaluating the physical properties of the soil after the consortium. experimental design was randomized blocks as a factorial 2x2, and an additional treatment that was corn cultivation single, with four replications. The treatments consisted two intercropping systems: corn intercropped with Brachiaria brizantha in the row, and corn intercropped with Brachiaria brizantha in space between two rows, and two times of sowing Brachiaria brizantha: simultaneously corn, and twenty-five days after sowing corn. The seed was planted mechanically in no-tillage system, with spacing between the lines of 0,70 m. The ears were harvested by hand and in the laboratory were evaluated: yield components and productivity. Brachiaria brizantha-MG-4 was sown and harvested manually. We evaluated the production of fresh and dry mass and yield components. For soil analyzes the soil was sampled at 0-0.10 and 0,10-0,20 m. Were determined the total porosity, macroporosity and microporosity. The results demonstrated that the production components of Brachiaria brizantha were lower when it was sown twenty-five days after sowing corn, and between sowing systems when Brachiaria brizantha was sown in line. There was no reduction in grain yield of maize intercropped with Brachiaria system independent and sowing date. The consortium of pasture with corn increased the total porosity, and reduced soil bulk density.

“…In response to this problem, farmers have adopted a conservation tillage system such as no-tillage as a soil-protecting measure (Studder t & Echeverría 2000, García-Préchac et al 2004). In conservation-tillage systems, litter and soil organic matter tend to concentrate in the upper 5 cm layer of soil (Dominguez et al 2005).…”

Importance of diet in the growth, survivorship and reproduction of the no-tillage pest Armadillidium vulgare (Crustacea: Isopoda)Importancia de la dieta en el crecimiento, la supervivencia y la reproducción de Armadillidium vulgare (Crustacea: Isopoda) plaga en siembra directa ABSTRACTThe studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybean leaf litter has high nutritive value which allows A. vulgare to grow faster, survive longer, and have higher fecundity favoring the population increase and turning it into a crop pest. Growth and survivorship of juveniles and adults, egg incubation period, offspring number per female and offspring mean body weight were determined in individuals fed with leaf litter of soybean, sunfl ower, wheat and pasture. The growth rate coeffi cient, k, in juveniles was higher for soybean, intermediate for pasture and lower for sunfl ower. Adult growth was faster under the soybean diet. Survivorship under soybean and pasture was longer than under sunfl ower and wheat in both juveniles and adults. The reproductive parameters were similar in all diets, food did not generate any change in the reproductive aspects of A. vulgare. Results of the present study represent a source of information about the A. vulgare biology under different diets of agricultural origin to establish the basis for Integrated Management of this species as pest. Under soybean litter provision A. vulgare found the best conditions for faster growth, longer survival and relatively higher fecundity. In fi elds with soybean as preceding crop or in systems with high frequency of soybean in the crop rotation a more abundant population of A. vulgare would be found as well as with larger individuals which could cause more damage to the following crop in the rotation.Key words: crop leaf litter, food quality, herbivore, N content. RESUMENLos estudios sobre Armadillidium vulgare como plaga son virtualmente nulos a nivel mundial. Sin embargo, en los sistemas bajo siembra directa esta especie ha encontrado un ambiente adecuado para su desarrollo y se ha convertido en una plaga importante en algunos cultivos en Argentina. Se ha demostrado que la composición de los vegetales afecta la biología de los isópodos. Nuestra hipótesis fue que los residuos vegetales de la soja tienen un valor nutritivo alto lo cual permite a A. vulgare crecer más rápido, sobrevivir más y tener una fecundidad elevada favoreciendo el incremento poblacional y convirtiéndolo en plaga de cultivos. El crecimiento y la reproducción de juveniles y adultos, el período de incubación, el número de crías por hembra y el peso medio de las crías fueron determinados en individuos alimentados con residuos de soja, girasol, trigo y pastura. El coefi ciente de la tasa de crecimiento, k...
