The objective was to verify the influence of winter crops under management mechanical (roller knife) and chemical (glyphosate), on soil physical properties and yield of soybeans. The experiment was carried out at the field under randomized block design in tracks scheme. The treatments consisted of four different winter crops (oats IPR 126, wheat BRS Tarumãt crambe FMS Bright and forage radish cultivar common) in tracks A and management different (chemical and mechanical) in bands B. The soil properties (macroporosity, microporosity, total porosity and density) were determined by collecting soil core in layers 0-10 and 10-20 cm depth, penetration resistance was determined with the aid of a penetrometer impact to a depth of 30 cm. The soybean harvest was held on 03/12/13, collecting two lines of the floor area of each plot. The evaluations were carried out after the winter crop management and post-harvest of soybeans. There was no significant difference in the interaction of the factors to the values of the porosity in the layer 0-10 cm of soil. As to the values obtained for the penetration resistance of the soil, it was found that the oat (0.91 MPa) and crambe (1.43 MPa) provided significant differences in the layer 0-5 cm depth, after the cycle of winter crops. Winter crops and different managements not affect soybean yield.

“…Estes resultados corroboram com os obtidos por Braz et al (2006), que não observaram diferença estatística na massa de mil grãos do trigo cultivado em sistema plantio direto em sucessão a diferentes culturas de cobertura e diferem dos resultados relatados por Teixeira Filho et al (2007), que encontraram efeito significativo de diferentes doses de nitrogênio em cobertura na massa de cem grãos do trigo. Entretanto, o aumento da massa de grãos, normalmente associado à maior disponibilidade de nitrogênio durante as fases de floração e início do (a) enchimento de grãos, não garante necessariamente maior produtividade da cultura do trigo (DIDONET et al, 2000).…”

“…Seus múltiplos efeitos têm sido constatados na proteção do solo, na elevação dos teores de matéria orgânica, no aumento da capacidade de troca catiônica e da ciclagem dos nutrientes das camadas mais profundas para a superfície (AMABILE; FANCELLI; CARVALHO, 2000). Muitos autores têm confirmado o aporte de nitrogênio proveniente do processo biológico promovido por bactérias diazotróficas e promotoras do crescimento vegetal, com o cultivo de leguminosas antecedendo as culturas econômicas (AMADO; MIELNICZUK; FERNANDES, 2000;AITA et al, 2001;SILVA et al, 2008;MARRERO et al, 2009).…”

A adubação verde ainda é uma prática pouco utilizada na cultura do trigo, embora proporcione benefícios do ponto de vista econômico e da preservação dos recursos naturais. Este estudo foi realizado em Dourados-MS, Brasil, com o objetivo de avaliar o efeito do cultivo de crotalária (Crotalaria juncea) e ervilhaca peluda (Vicia villosa) como adubos verdes, associados a doses de nitrogênio mineral em cobertura, no desempenho agronômico do trigo em sistema plantio direto. Os tratamentos foram constituídos pelos adubos verdes, um tratamento-testemunha em pousio e seis doses de nitrogênio mineral em adubação de cobertura do trigo: zero, 30, 60, 90, 120 e 150 kg ha -1 , utilizando-se a ureia como fonte de nitrogênio. Foram realizadas avaliações de massa seca das coberturas vegetais, teores de nitrogênio na parte aérea dos adubos verdes e nas folhas de trigo, altura de plantas, número de perfilhos produtivos, massa de mil grãos, peso hectolitro e produtividade. Verificou-se que o cultivo de adubos verdes antecedendo a semeadura do trigo promove acréscimos significativos na produtividade da cultura, especialmente quando cultivado em sucessão à crotalária. A resposta do trigo à aplicação de nitrogênio mineral variou em função da cultura antecessora. Palavras chave: Adubação nitrogenada, crotalária, ervilhaca peluda, Triticum aestivum AbstractGreen manure is still a not widely used practice in wheat crop, although economic benefits and conservation of natural resources can be observed due to the adoption of this practice. This study was carried out at the Dourados, Mato Grosso do Sul State, Brazil, with the objective of evaluating the effect of sunn hemp (Crotalaria juncea) and hairy vetch (Vicia villosa), associated with levels of mineral nitrogen topdressing in the agronomic performace of wheat crop under no-tillage. The treatments were constituted by green manures, fallow as a treatment-control and six doses of mineral nitrogen topdressing: zero, 30, 60, 90, 120 and 150 kg ha -1. Urea was used as nitrogen source. Evaluations of dry mass of cover crops, nitrogen contents in green manures shoot and in wheat leaves, plant height, number of productive tillers per plant, one thousand-grains weight, hectolitric weight and yield were made. It was concluded that the use of green manures before wheat seeding promotes significant increases in crop yield, mainly when planted over to sunn hemp. The wheat yield response to mineral nitrogen application varied according to the preceding crop.

“…Alterations in the soil structure due to management practice have frequently resulted in high soil density, making root penetration difficult (Hamza & Anderson, 2005). Cultural practices, together with soil preparation can affect soil structure, altering density and other related physical aspects (Silva et al, 2008).…”

Soil is the basis underlying the food production chain and it is fundamental to improve and conserve its productive capacity. Imbalanced exploitation can degrade agricultural areas physical, chemical and biologically. The objective of this study was to evaluate some soil physical properties and their relation with organic carbon contents of a Humic Dystrudept under conventional tillage (CT) and no-tillage (NT), for 12 years in rotation (r) and succession (s) cropping systems. The experiment was carried out in Lages, SC (latitude 27 ° 49 ' S and longitude 50 ° 20 ' W, 937 m asl), using crop sequences of bean-fallow-maize-fallow-soybean in conventional tillage rotation; maize-fallow in conventional tillage succession; bean-oat-maize-turnip-soybean-vetch in no-tillage rotation; and maize-vetch in notillage succession. The experimental design was completely randomized with four replications. The soil samples were collected in the layers 0-2.5, 2.5-5, 5-10, and 10-20 cm. The following properties were analyzed: soil density, porosity, aggregate stability, degree of flocculation, water retention, infiltration, mechanical strength, and total organic carbon. Soil aggregation in the surface layer (0-5 cm) was better in the no-tillage than the conventional system, related to higher microporosity, organic carbon contents and water retention capacity, indicating that a periodical tillage of this soil is unnecessary. Infiltration was highest in no-tillage with crop succession.Index terms: crop rotation, crop succession, no-tillage, soil management.(
