In pursuit of maximum grain yield farmers in the North China Plain usually apply excessive N fertilizer, resulting in wasted resources and environmental pollution. To assess the economic and environmental performances of different nitrogen rates will be conductive to sustain cleaner crop production. An 8-year field experiment was carried out with four treatments, N0 (0 kg ha−1 for winter wheat and summer maize), N1 (168 kg ha−1 for winter wheat and 129 kg ha−1 for summer maize), N2 (240 kg ha−1 for winter wheat and 185 kg ha−1 for summer maize) and N3 (300 kg ha−1 for winter wheat and summer maize), on the double cropping at Dawenkou research field (36°11’N, 117°06’E), Shandong Province, China. The crop production, soil physical-chemical parameters, and greenhouse gas emission are measured and the economic and environmental performances are assessed. The optimal nitrogen rate obtained the highest grain yield of summer maize in 4 of 8 year and was equivalent to conventional N rate in the other years. The nitrogen partial factor productivity and agronomic efficiency of optimal nitrogen rate was 63% and 58% higher than that of conventional nitrogen rate. The optimal nitrogen rate effectively decreased soil bulk density and increased weight percentage of water-stable aggregate and activities of urease and invertase compared to conventional nitrogen rate, which improved soil productivity. The fertilizer nitrogen loss and global warming potential of optimal nitrogen rate reduced by 76% and 35% compared to conventional nitrogen rate. The annual greenhouse gas intensity of optimal nitrogen rate decreased by 14–35% compared to others. The net ecosystem economic budget under optimal nitrogen rate is 252–604 $ ha−1 yr.−1 higher than other addition levels. The optimal nitrogen rate produces more grains and obtains higher economic and environmental benefits.

“…Given that the density of the soil is obtained by its weightvolume relation, that is, volume occupied by the particles of the soil in a certain volume; it depends on the structure and management of the area, allowing variations for the same soil type (Bonini & Alves, 2012). Data from this study are above of what is considered ideal (Bonini et al, 2015;Rienzi et al, 2016), hindering the plants .development due to its lower aeration, and is accordance with Maio et al (2011), who studying some soil properties verified the influence of treatments only on the degree of flocculation, the other soil characteristics not being influenced positively or negatively. These results indicate that legume treatments are not yet contributing to improve soil physical quality, but have already improved the soil organic matter content, which is of utmost importance for its structure recovery.…”

The objective of this study was to study the physical attributes and the organic matter of a Red-Yellow Oxisol cultivated with Urochloa decumbens pasture in recovery with different introducing ways of Stylosanthes cv. Campo Grande. The experiment was conducted at the Agency for Agribusiness Technology of São Paulo (APTA), in the municipality of Andradina/ SP, between October 2016 and September 2017. The experimental design was the randomized complete block design with four replicates and the treatments were composed of six strategies (partial desiccation, total desiccation, scarification, "rome" harrowing and plowing + harrowing.) in the no-tillage legume in the pasture, in addition to the control. Stability of aggregates, flocculation, soil porosity, organic matter and soil texture were evaluated in three layers: 0-0.10; 0.10-0.20 and 0.20-0.40 m. Soil organic matter content was higher in the topsoil layers (from 15.75 to 17.75 mg dm -3 ) and decreased with depth (from 10.50 to 11.50 mg dm -3 ). The indicated macroporosity was below the value considered ideal for the plants development. Studied treatments did not influence the organic matter content, porosity and soil density. Soil quality was influenced up to 0.20 m with the introduction of stylosanthes, regardless of the adopted management.Recuperação de pastagem utilizando Estilosantes cv. Campo Grande: efeito na qualidade do solo RESUMO: Objetivou-se estudar atributos físicos e a matéria orgânica de um Latossolo Vermelho Amarelo cultivado com pastagem de Urochloa decumbens em recuperação com diferentes formas de introdução de estilosantes cv. Campo Grande. O experimento foi realizado na Agência Paulista de Tecnologia dos Agronegócios (APTA), no município de Andradina/SP, entre outubro de 2016 e setembro de 2017. O delineamento experimental foi em blocos ao acaso, com quatro repetições e os tratamentos foram compostos por seis estratégias (dessecação parcial, dessecação total, escarificação, gradagem rome e aração +gradagem) em plantio direto da leguminosa na pastagem, além da testemunha. Foram avaliados a estabilidade de agregados, floculação, porosidade, matéria orgânica e textura do solo, em três camadas: 0-0,10; 0,10-0,20 e de 0,20-0,40 m. O teor de matéria orgânica no solo foi superior nas camadas superficiais (15,75 a 17,75 mg dm -3 ) e diminuiu em profundidade (10,50 a 11,50 mg dm -3 ). A macroporosidade indicada ficou abaixo do valor considerado ideal para o desenvolvimento das plantas. Os tratamentos estudados não influenciaram o teor de matéria orgânica, a porosidade e densidade do solo. A qualidade do solo foi influenciada até 0,20 m com a introdução do estilosantes, independente do manejo adotado.

-The rate of swine wastewater application (SW) in agricultural production could result in the replacement of chemical fertilizers. However, SW destroys soil physical properties by decreasing pore bulk, which negatively affects both crop yield and development. In this context, this study aimed at monitoring the influence of swine wastewater as a cover fertilizer in maize and black oats in sequence on soil physical properties. Five application rates (0, 100, 200, 300 and 537 m 3 ha -1 equivalent to 0, 11.2, 22.3, 33.5 and 60 kg ha -1 N, respectively, based on the average nitrogen concentration in SW) were tested with four replications each. In the studied area, soil porosity, density, and water content, before maize sowing and at the end of the cycles of maize and black oats, were determined by the volumetric ring method. Data were submitted for regression analyses. There was a reduction in the macroporosity and total porosity of the soil when the SW application rate, before maize cultivation, was higher. The introduction of black oats helped to improve the physical quality of the soil and reduced the compaction of the surface layer from 0 to 15 cm and 100 to 300 m 3 ha -1 SW rates.Keywords: Swine manure.

ATRIBUTOS FÍSICOS DO SOLO APÓS APLICAÇÃO DE ÁGUA RESIDUÁRIA DE SUINOCULTURA APLICADA EM COBERTURA NA CULTURA DO MILHO E CULTIVOSEQUENCIAL DE AVEIA PRETA RESUMO -As taxas de aplicação de águas residuárias de suinocultura (ARS) utilizadas na produção agrícola podem substituir a adubação convencional, mas também podem prejudicar atributos físicos do solo pela diminuição do volume de poros, e consequentemente o rendimento e desenvolvimento das culturas. Neste contexto, o objetivo deste trabalho foi monitorar a influência do uso da água residuária de suinocultura como adubação de cobertura na cultura do milho e aveia preta em sequência sobre atributos físicos do solo. Cinco taxas de aplicação (0; 100; 200; 300 e 537 m 3 ha -1 sendo equivalentes a 0; 11,2; 22,3; 33,5 e 60 kg ha -1 de N, respectivamente, baseado na concentração média de N na ARS) foram testadas, com quatro repetições cada. No solo, foram determinados porosidade do solo, densidade, teor de água antes da semeadura do milho e ao final dos ciclos do milho e aveia preta, pelo método do anel volumétrico. Os dados foram submetidos a análises de regressão. Houve redução da macroporosidade e porosidade total do solo quanto maior a taxa de aplicação na cultura do milho. A introdução da aveia preta contribuiu para melhorar a qualidade física do solo e reduziu a compactação na camada superficial de 0-15 cm, para taxas de ARS de100 a 300 m 3 ha -1.
