“…In Cerrado biome, cover crop qualitative characteristics associated with soil and climate conditions may alter decomposition rates, changing the soil nutrient availability dynamics (TORRES;PEREIRA, 2008;PACHECO et al, 2017), determining the time crop residues should remain on the soil surface for a faster decomposition (TORRES et al, 2014). Most of the studied and grown leguminous used as mulch in Brazilian cerrado are Crotalaria juncea (sunn hemp) (TORRES et al, 2014), Canavalia ensiformis (jack bean) (COLLIER et al, 2011), Stylosanthes (stylosanthes) (PEREZ; SMYTH; ISRAEL, 2007), and Cajanus cajan (pigeon peas) (ROSA et al, 2011).…”

“…The largest residual dry matter was found for spontaneous vegetation, which means it remained longer in the soil (Figure 3). This finding can be attributed to the presence of Poaceae family plants in the spontaneous vegetation composition; these plants usually produce residues with longer permanence since they present a high C/N relationship (ROSA et al, 2011).…”

Leguminous species can improve nutrient cycling and chemical quality of Oxisols, resulting in higher productivity of intercropped crops. Thus, this research aimed to evaluate the decomposition rate and nutrient accumulation in legume stubble, as well as its contribution to soil chemical attributes, the growth of baru trees (Dipteryx alata Vogel), and yield of intercropped maize in an agroforestry system. The experiment was developed during the crop years of 2010-2011 and 2011-2012, in Goiás State, Brazil. The experimental design was a randomized block with five replicates. Leguminous species consisted of sunn hemp (Crotalaria juncea), jack bean (Canavalia ensiformis), pigeon pea (Cajanus cajan), Stylosanthes (Stylosanthes macrocephala - 20% and Stylosanthes capitata - 80%), and spontaneous vegetation (control treatment). The decomposition rates of legume and spontaneous vegetation residues remained unchanged in the agroforestry system. Sunn hemp, jack bean, and Stylosanthes plants are advantageous options for total accumulation of nutrients. However, sunn hemp grown as straw cover for next crop seasons increases the available phosphorus levels in the soil and productivity of maize cobs. With this coverage, maize productivity values were up to 24% higher than were those with maize growing on spontaneous vegetation, besides having no effect on the growth of baru trees.

“…Segundo Rosa et al (2011) a maneira mais eficaz para maximizar o aproveitamento de nutrientes, garantido melhores produtividades e mantendo a palhada na superfície do solo, é com o uso do sistema plantio direto (SPD) aliado à rotação de culturas utilizando plantas de cobertura que garantam melhorias ao sistema.…”

O milho é um dos cereais mais importantes cultivados no mundo, com o sistema plantio direto sendo a forma de plantio que mais cresce, usando-se semeadoras especiais com a finalidade de manter ou aumentar o conteúdo de matéria orgânica, além disso, são capazes de melhorar as qualidade físicas, químicas e biológicas do solo. Objetivou-se nesse trabalho avaliar o desenvolvimento e a produtividade do milho consorciado com feijão de porco para a implantação do sistema plantio direto na região do Cariri cearense, em Assaré-CE. O experimento foi desenvolvido em delineamento em blocos casualizados em esquema fatorial 3 x 2, com quatro repetições, totalizando 24 observações. O primeiro fator foram três níveis de adubação de fundação (0, 100 e 150%, sendo estas porcentagens em relação à dose recomendada), e o segundo fator foi referente à calagem (com e sem calcário). Os resultados permitiram concluir que a adição de adubo mineral a partir da dose ideal elevou os índices de desenvolvimento e produtividade da cultura do milho, com a calagem não apresentando resposta significativa em função do alto valor de saturação por bases inicial do solo.

“…The use of cover crops promotes greater nitrogen cycling in agroecosystems, boosting the availability of nutrients to crops (BlancoCanqui et al, 2014). Considering the predominance of dystrophic soils in the region, the use of leguminous plants which are able to fix atmospheric nitrogen as cover crops, provides a potential benefit by reducing the use of fertilizers (Rosa et al, 2011;Albuquerque et al, 2013). This is especially true when considering nitrogenous fertilizers, which are expensive and can be lost by leaching or volatilization (Mahama et al, 2016).…”

No-tillage is an agricultural system that is proposed as a sustainable soil management system. This paper aims to evaluate the short-term effects of cover crops on a no-tillage system, by assessing a number of physical and chemical attributes of soil of the Brazilian Amazon region. The experiment was carried out in a typical Ferralsol under a no-tillage system from March to December, 2014. A randomized block design, with four replicates was used. The performance and effects of fourteen cover crops (Cajanus cajan, Canavalia ensiformis, Crotalaria juncea, Crotalaria ochroleuca, Crotalaria spectabilis, Stizolobium aterrima, Stizolobium cinereum, Pennisetum glaucum, Sorghum bicolor, Sorghum sudanense, Urochloa brizanha cv. Xaraés, Urochloa brizantha cv. Piatã and Urochloa ruziziensis and Zea mays) and fallow (control treatment) on the soil quality were assessed. The cover crops were sown in the off season in April 2014, before the summer crop (maize). The levels of P, K, Ca 2+ , Mg 2+ , Al 3+ , H+Al, saturation by aluminum, sum of bases, organic matter, pH and resistance to soil penetration were evaluated following the end of the cover crops growth. Some near-surface soil attributes were affected by the cover crops. Urochloa species improved the levels of potassium in the soil at depths up to 5 cm below the surface. The highest penetration resistance was observed in the superficial layer between 12 and 16 cm deep, with penetration resistance values varying between 2472 and 2912 kPa. The Urochloa exhibited satisfactory agronomic performance when grown under a simulated crop livestock integration system. It is concluded that the use of cover crops in a no-till system has the potential to improve the chemical quality of soil in the Southwestern Amazon region.
