title: Sistemas de manejo do solo e de produção de algodão, soja e milho em solo arenoso do cerrado da Bahia

description: The objectives of this study are to evaluate tillage and crop systems on soil fertility, soil carbon stock changes at depth and yield performance of soybean, cotton, and maize grown in the sandy soil of western Bahia, Brazil. Four treatments consist of conventional tillage and monocropping of Gossypium hirsutum L. r latifolium, soybean, and corn; and six treatments with these cash crops rotations with Urochloa ruziziensis (ruzigrass) and Sorghum bicolor as cover crops, and Crotalaria ochroleuca as a green manure, under no-tillage. Each experimental plot measure 400 m2 (20 m x 20 m). Cotton, soybean, and maize are harvest at three random points, each composed of 4 rows of 5 m in length. The experimental design was a randomized block design with four replicates. Soil samples are collected at three depth intervals (0-10 cm, 10-20 cm and 20-40 cm), and in some years until 40-60 cm and 60-100 cm. "Soil samples are collected at three depth intervals (0-10 cm, 10-20 cm and 20-40 cm), and in some years until 40-60 cm and 60-100 cm.

pH in water (soil:water = 1:2.5); available phosphorus and exchangeable potassium, extracted by Mehlich-1; exchangeable calcium and magnesium, extracted by KCl 1mol L-1; potential acidity, extracted by calcium acetate, 0.5 mol L-1, pH 7.0; soil organic matter (by wet combustion followed by colorimetric determination)" From the beginning of the experiment until 2017, soil organic carbon concentration was measured by wet combustion followed by colorimetric determination. The SOC concentration, expressed on a volumetric basis, was converted to a gravimetric basis according to the pedotransfer function, using the total sand concentration. After 2018 soil organic carbon was determined by dry combustion in a C and N elemental analyzer (Perkin Elmer Elemental Analyzer 2400 Series II) according to the Pregl-Dumas method (Nelson & Sommers 1996). Soil samples are collected at three depth intervals (0-10 cm, 10-20 cm and 20-40 cm), and in some years until 40-60 cm and 60-100 cm. Soil bulk density was determined using a volumetric ring. Soil samples are collected at three depth intervals (0-10 cm, 10-20 cm and 20-40 cm), and in some years until 40-60 cm and 60-100 cm. Soil mineralogy was not performed. Granulometry corresponding to 463, 143 and 394 g kg-1 of clay, silt and sand, respectively. Soil samples were subjected to the BioAS method.

title: Arranjos de culturas agrícolas e de plantas de cobertura em sistema de plantio direto na palha para o aumento da produtividade agrícola e da taxa de sequestro de carbono orgânico no solo argiloso do Cerrado de Goiás

description: Na safra 2014/2015, foi implantado um experimento de campo, com quinze tratamentos envolvendo esquemas de rotação ou sucessão com as culturas de soja, feijão, milho (primeira e segunda safra) e algodão (primeira e segunda safra), além de plantas de cobertura (Pennisetum glaucum, Cajanus cajan, Urochloa ruziziensis, Crotalaria spectabilis e Crotalaria ochroleuca). O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. Cada parcela experimental tem 12 m de largura por 14 m de comprimento (12 m × 14 m = (168 m2). O algodão, o feijão e a soja são colhidos mecanicamente em 4 fileiras completas, e o milho é colhido manualmente em três pontos aleatórios, cada um composto por 4 fileiras de 5 m de comprimento. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. As amostras de solo são coletadas em seis intervalos de profundidade (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, 40-50 cm, 50-60 cm) e, em alguns anos, até 60-100 cm. SWIFT, R. S.

title: Agricultura familiar conservacionista no Acre

description: Hipótese - A agricultura de conservação, promovendo o mínimo de perturbação do solo (plantio direto), manutenção de uma cobertura permanente do solo e diversificação de espécies vegetais, constrói a saúde do solo e garante produtividade e renda para os agricultores familiares e também reduz os impactos ambientais. O experimento foi instalado em esquema de parcelas subdivididas, em delineamento de blocos casualizados, com três blocos. Os dois sistemas de preparo do solo (PC e PD) foram comparados nas parcelas principais (20 m por 50 m). Foram avaliados cinco sistemas de cultivo nas subparcelas (10 m por 20 m): (a) SB, que é o modo tradicional de cultivo do solo na região, sem calagem (Lm) e adubação; b) Espécies de leguminosas e/ou gramíneas (LG) de cobertura sem Lm e P; (c) LG com P (LGP) e sem Lm; (d) LG sem P e com Lm usando calcário dolomítico (LGLm); e (e) LG com P e Lm (LGPLm). A cada cinco anos, o solo é amostrado na camada de 0 cm a 100 cm, com subcamadas de 0–5, 5–10, 10–15, 30–40, 50–75 e 75–100 cm. Amostras de referência também são coletadas de florestas não perturbadas adjacentes ao experimento, também com três repetições de campo. Nos demais anos, a amostragem de solo é definida de acordo com o objetivo da coleta. As amostras de solo são analisadas de acordo com o manual de métodos da Embrapa. As profundidades são descritas em 11. Nas amostras coletadas foram utilizados os métodos de combustão úmida (Walkley-Black) e de combustão seca (análise elementar). A combustão úmida foi utilizada na maioria das amostras até 2015. Após este ano, a combustão seca sempre foi usada. As amostras de solo são analisadas de acordo com o manual de métodos da Embrapa. O solo não foi analisado para mineralogia. O método da pipeta sempre foi usado para textura. O solo foi analisado quanto à atividade das enzimas arilsulfatase e beta-glicosidase entre 2021 e 2022.
