Resumo: Soil management must keep the soil physical properties next to the original conditions in natural systems to assure the sustainability of agricultural systems. This review synthesizes the effects of conventional tillage, minimum tillage and no-tillage systems of annual crops, on soil physical properties as bulk density, porosity, soil resistance to root penetration, infiltration speed, hydraulic conductivity,compressibility, organic matter level, soil aggregate size and stability. No-tillage presents advantages on organic matter level, size and stability of aggregates, compressibility and hydraulic conductivity but has limitations on bulk density and resistance to root penetration. Minimum tillage with chisel plow is specially efficient in relation to infiltration speed and hydraulic conductivity, and intermediate between conventional and no-tillage in other aspects. Conventional tillage with total pulverization of soil surface,mainly on tropical conditions, presents the less favorable scores on soil physical properties, close to minimum tillage and no-till only in few circumstances, and frequently the most different from the natural conditions. The conservation systems by their side, despite of similarities in some aspects with natural conditions, are not able to reproduce the conditions of natural forests, savannas or natural pastures, but are in the sustainability direction.

Esta revisão sintetiza os efeitos de três sistemas de manejo de solo (convencional, mínimo e direto) em culturas anuais sobre as propriedades físicas do solo como densidade, porosidade, resistência à penetração, velocidade de infiltração, condutividade hidráulica, compressibilidade, nível de matéria orgânica, tamanho e estabilidade de agregados. O plantio direto apresenta vantagens nos níveis de matéria orgânica, na estabilidade de agregados, na compressibilidade e na condutividade hidráulica, mas tem suas limitações quanto à densidade do solo e resistência à penetração. O preparo mínimo à base de escarificação apresenta-se especialmente eficiente na velocidade de infiltração, na condutividade hidráulica e na resistência à penetração, sendo intermediário entre convencional e direto nos demais aspectos. O preparo convencional, principalmente em condições tropicais, apresenta os indicadores menos favoráveis para propriedades físicas do solo, normalmente mais distante das condições da cobertura vegetal original e, em certas situações, aproximando-se do preparo mínimo e do plantio direto. Nesse particular, os sistemas conservacionistas se aproximam em alguns aspectos das condições naturais, mas não reproduzem as condições das coberturas naturais originais de mata, cerrado ou campos nativos, mesmo que estando na direção da sustentabilidade.UEL2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/243610.5433/1679-0359.2006v27n2p205Semina: Ciências Agrárias; Vol. 27 No. 2 (2006); 205-220Semina: Ciências Agrárias; v. 27 n. 2 (2006); 205-2201679-03591676-546Xreponame:Semina.
