Soil organic carbon (SOC) was assessed in a long‐term (19 yr) experiment comparing conventional tillage (CT) and no‐tillage (NT) management systems various winter cover crop treatments Rhodic Hapludox southern Brazil. After 19 yr, NT resulted 6.84 Mg C ha −1 , the upper soil layer (0–10 cm), which represented 64.6% more than CT. In 0 to 20 cm layer, system sequestered 1.24 yr while CT 0.96 . Independent of management, fallow treatment lowest SOC stocks 40‐cm depth compared all other...
Embora associada à adoção de tecnologias conservação do solo, a intensificação dos sistemas produção agropecuária tem induzido um principais problemas enfrentados pelos agricultores, compactação seja em plantio direto ou convencional e pastagem. Este estudo foi realizado Rio Verde, GO, Latossolo Vermelho Amarelo, nos seguintes sistemas: há 14 anos (SD14); oito (SD8); dois (SD2); preparo (PC); pastagem (P) floresta (F). A resistência penetração solo determinada utilizando-se o penetrômetro...
The concept of a no-tillage system (NTS), or “Sistema Plantio Direto,” was established in Brazil from the evolution (NT) “Plantio given edaphoclimatic conditions and need to promote chemical, physical biological improvements cultivated soils. While Direto” is conservationist practice, presents itself as an agricultural production based on simultaneous adoption minimum soil disturbance, maintenance permanent cover crop rotation. This study reviews [...]
Uma nova abordagem para adoção do método Perfil Cultural em condições de solos tropicais é aqui tratada. Analisou-se a evolução desse desde seu início na França, década 1960, até proposta sua utilização no estudo manejo tropicais. Tal mostra-se eficiente diagnóstico qualitativo estado físico dos campo, orientação amostragem solos, efeitos da antropização, visualização das interações físicas, químicas e biológicas nos estudos mecânica solo campo organização estrutural agrícolas, além auxiliar...
Sugarcane, which involves the use of agricultural machinery in all crop stages, from soil preparation to harvest, is currently one most relevant crops for agribusiness Brazil. The purpose this study was investigate physical properties and root growth a eutroferric red Oxisol (Latossolo Vermelho eutroférrico) after different periods under sugarcane. carried out cane plantation Rolândia, Paraná State, where treatments consisted number cuts (1, 3, 8, 10 16), harvested as green burned sugarcane,...
The origins, history, and recent advances in Conservation Agriculture (CA) are reported. CA is now practiced worldwide on some 200 million hectares, important for mitigating climate change ensuring food security. Its bedrock Zero Tillage (ZT) with crop rotation retention of residues. approaches Organic (OA) when coupled to biological control providing opportunity OA become truly sustainable. Ley Farming (LF) agroforestry ZT carbon sequestration land use intensification. Hidden cost: each ton...
Agron. J. 100:1013–1019 We regret that a key citation (Sisti et al, 2004) was omitted from our recently published article. On p. 1014, second column, first paragraph, the last sentence should read “…the lack of SOC accumulation under NT or CT treatments, according to Sisti al (2004), related low level external input N system”. Omission in text and its reference list mistake. offer sincere apologies these authors. The was: Sisti, C.P.J., Santos, H.P., Kochhann, R., Alves, B.J.R., Urquiaga,...
The purpose of the study was to evaluate use and suggest possible adjustments indicators biodiversity loss for LCA proposed by Chaudhary Books (2018). For this, we analyzed soybean production in Brazil. Potential damage has been determined all Brazilian ecoregions: Amazon; Atlantic forest; Caatinga; Cerrado; Pampas; Pantanal. Two dimensions assessment were considered – global regional addition Average-country. An adjustment vulnerability coefficient Average-country Brazil: Regional Species...
A possibilidade de uma crise na agricultura familiar referente à sucessão do empreendimento se mostra preocupante medida em que alguns filhos abandonam a propriedade por não poder ou querer exercer profissão agricultor. Esta é situação pode comprometer viabilidade socioeconômica assentamentos rurais da reforma agrária. Neste sentido, o objetivo deste estudo caso foi conhecer os anseios, as perspectivas futuro e realidade vivem jovens moradores assentamento Florestan Fernandes, localizado no...
Abstract Soil fertility is the result of interactions between physical and chemical soil attributes, affecting its biological component, which in turn feeds back to attributes. The No‐Till System (NTS) main modality Conservation Agriculture, essential achieving farming sustainability conserving fertility. However, farmers often fail adopt three principles NTS: (a) minimum mechanical disturbance, (b) permanent cover (c) plant diversification; therefore, system currently requires a quality...
This work aims to evaluate the soil physical properties affected by cover crop rotation and management in a long-term experiment southern Brazil. The was established 1986, with treatments combining six winter two tillage systems (conventional no tillage). Bulk density, porosity, aggregate-size class distribution, organic carbon content of aggregates were determined at depths. density not treatments. disturbance plowing enhanced macroporosity, decreased microporosity, promoted formation...
O sistema de plantio direto atingiu, no Estado do Paraná, cerca dois milhões hectares, nos últimos anos, e um dos seus principais entraves é a falta semeadoras-adubadoras apropriadas para operação em solos argilosos origem basáltica. Portanto, estudou-se MAGNUM 2850 PD quanto à demanda energética desempenho operacional, com finalidade oferecer subsídios ao seu aperfeiçoamento, acordo realidade paranaense. Observou-se que o esforço tração variou função da umidade características mecânicas...
The effects of no-tillage with and without crop rotation previously planned, conventional system including ploughing disc harrowing on soil particles aggregation were evaluated compared native forest an Red distroferric Oxisol high clay content from western Paraná State. Soils sampled all treatments, adequately stored indices determined were: the mean weight diameter (MWD), geometric (GMD) aggregate stability index (AS %). Soil organic carbon was also for different treatments. results showed...
Phosphorus is an essential element for all living organisms and important also agricultural production. The content of P in most soils Brazil low. In order to supply the plant needs soil fixation, application fertilizer required. Among various options fertilizers market, totally acidified phosphates are usually commercialized. evaluation efficiency reactive natural as due increase utilization cheaper sources P. experiment was carried out green house, using a Nitossolo. experimental design...
The structural stability and restructuring ability of a soil are related to the methods crop management preparation. A recommended strategy reduce effects preparation is use rotation cover crops that help conserve restore structure. aim this study was evaluate quantify homogeneous morphological units in under conventional mechanized tillage animal traction, as well assess effect on structure intercropping with jack bean (Canavalia ensiformis L.). Profiles were analyzed April 2006, five...
With the rise of restrictions imposed by law for gases emission, several technologies both petrodiesel (PD) or diesel engines are been applied, such as sulfur reduction and injection electronic command, followed recirculation and/or after-treatment. The utilization biofuels is considered an interesting option pollutants reduction. In this study was evaluated performance on short duration tests (minor period than factory indication lubricant lifespan) Diesel engine fueled with four vegetable...
In evaluation of soil quality for agricultural use, structure is one the most important properties, which influenced not only by climate, biological activity, and management practices but also mechanical physico-chemical forces acting in soil. The purpose this study was to evaluate influence conventional on microstructure a Latossolo Vermelho distroférrico típico (Rhodic Hapludox) an experimental area planted maize.

Abstract Modern agriculture has had to face complex environmental issues, many of which result from land use, includes the degradation its fertility properties. Soil quality is fundamental sustainability planet, as it also affects other natural resources. Therefore, must be seen a action for planet and evaluated using methodologies capable holistically relating impacts production systems, does Life cycle assessment (LCA) methodology. However, due lack suitable models, LCA still ineffective...
