“…As also observed for BD, the K a values in CR were greatest in the 0.0-0.1 m layer. These K a values are lower than those found by Cavalieri et al (2009) and by Rodrigues et al (2011) despite the differences in soil clay content between the soil in those studies and in the present paper.…”

The hypothesis of this study was that the absence of soil tillage in long-term no-tillage (NT) systems can be detrimental to soil aeration. The objective was to assess the aeration condition of an Oxisol (Rhodic Ferrasol), very clayey texture (750 g kg-1 of clay; 200 g kg-1 of sand), after 30 years of cultivation under NT. The physical property soil air permeability (Ka) is sensitive to changes in the soil pore system. Aside from Ka, the air-filled porosity (ε a) and indices of pore continuity (K1 and N), derived from the relationship between Ka and εa, were used as indices of soil aeration. From the soil layers 0.0-0.1 and 0.1-0.2 m, 240 undisturbed samples were collected along a transect perpendicular to the crop rows, at three sampling positions: corn plant row (CR); center of the interrow (INT); and the equidistant point between CR and INT (PE). The properties Ka and εa were determined at soil matric potentials (Ψm) of -2, -4, -6, -10, -30, and -50 kPa. Soil bulk density (BD) was also determined. The results confirmed the hypothesis. In the 0.0-0.1 m layer, Ka, K1, N and Ψa were significantly greater and BD significantly lower in CR than at the other sampling positions. At a Ψm of -10 kPa, the Ka of CR was 6.9 and 8.4 times higher than in PE and INT, respectively, in the 0.0-0.1 m layer. The properties Ka, K1 and N were sensitive enough to detect changes in the pore system and their differences between the sampling positions demonstrated the importance of the spatial location for soil sampling. Tilling the crop rows provides better soil aeration under NT.

“…Os maiores valores de Ds foram observados na profundidade de 0,1-0,2 m, em todos os tratamentos. Os valores de Ds medidos enquadramse dentro da faixa comumente observada em solos agrícolas de textura argilosa (Brady & Weil, 2007), especialmente na região estudada (Cavalieri et al, 2009, Figueiredo et. al 2009.…”

“…No-tillage could therefore contribute to the recovery of soil physical properties in the surface layer, which is often favoured by the presence of cover crops or the residual effect of crops used in rotation systems (Alves & Suzuki, 2004). The combined effect of crop residues on the soil surface with a continuous and deep network of macropores could increase soil hydraulic conductivity under no-tillage (Cavalieri et al, 2009). …”

“…Soil also fulfills an essential function as a regulator in the water cycle by filtering and retaining it, and is normally conditioned by conservationist management practices that guarantee structural stability and continuous preservation of organic matter (Silva et al, 2005;Cavalieri et al, 2009). …”

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.(
