-One way to prevent soil degradation is to monitor its structural quality through physical attributes and indicators. Thus, the objective of this work was to identify parameters that can be used together with the S-index to assess the soil structural quality of Latosols-Distrophic Red Latosol (DRL) and Eutroferric Red Latosol (ERL)-cultivated with maize after traffic-induced compaction by agricultural machinery. The experiment was conducted in a randomized block design in split-plots, with five treatments and four replications for each soil class. The treatments were: T0 = conventional tillage without additional compaction; T1, T2 and T3 = one pass of a 4, 7 and 10-Mg tractor, respectively; T4 = three passes of a 10-Mg tractor. The water retention curve, density, porosity and S-index of the soil layers 0-0.1, 0.1-0.2 and 0.2-0.3 m were evaluated. The DRL presented similar S-index (0.035 to 0.037) in the T0, T1 and T2, and these S-index were connected to soil macroporosity. Most S-index of the ERL were above 0.035, except for T4 due to its higher soil density. The S-index can be used as a complementary parameter for maize height and soil macroporosity to evaluate the structural quality of DRL.Keywords: Agricultural machinery traffic. Soil management.

ÍNDICE S COMO INDICADOR DA QUALIDADE ESTRUTURAL EM LATOSSOLOS COMPACTADOS CULTIVADOS COM MILHORESUMO -Uma maneira de prevenir a degradação do solo é monitorar a sua qualidade estrutural por meio de atributos e indicadores físicos. Dessa forma, objetivou-se com este trabalho verificar quais parâmetros podem ser utilizados junto com o índice S para a avaliação da qualidade estrutural do solo, após a compactação induzida por tráfego de máquinas agrícolas em um Latossolo Vermelho Distrófico (LVd) e em um Latossolo Vermelho Eutroférrico (LVef), cultivados com milho. O experimento foi conduzido em delineamento de blocos casualizados em parcelas subdivididas, com cinco tratamentos e quatro repetições, para cada classe de solo. Os tratamentos foram: T0= preparo convencional sem compactação adicional; T1, T2 e T3= uma passada do trator de 4, 7 e 10 t, respectivamente; T4= três passadas do trator de 10 t. Foram avaliadas nas camadas de 0-0,10; 0,10-0,20 e 0,20-0,30 m a curva de retenção de água, a densidade, a porosidade do solo e o índice S. Os valores do índice S no LVd foram semelhantes (0,035 a 0,037) no T0, T1 e T2, os quais estiveram relacionados à macroporosidade do solo. Para o LVef, a maioria dos valores do índice S situaram-se acima de 0,035, com exceção do T4, devido aos maiores valores de densidade do solo nesse tratamento. O índice S pode ser utilizado como um parâmetro complementar a altura do milho e a macroporosidade do solo, para a avaliação da qualidade estrutural em LVd.Palavras-chave: Tráfego de máquinas agrícolas.

“…The same authors also observed that the degree of soil mixing in the practice of the preparation modifies the manner of distribution of the organic material, where the CT becomes this relatively uniform distribution in the arable layer (0.0-0.2 m). Rossetti et al (2013) studying the organic matter content in different tillage systems have also observed that the higher content of OM lie in surface layers and that in the CT system, there is a decrease in these levels over time due to the action of microbial decomposition, combined with increasing aeration, soil temperature, fractionation and mixing of plant residues to the soil caused by this management system. In the NT system, the P content in the layer 0.0-0.1 m were higher at other systems in the year 2009 (5.40 mg dm ).…”

The different tillage systems interfere with soil chemical attributes mainly due to the site of preparation techniques. The aim of this study was to determine, in two time evaluation periods, the changes in soil chemical attributes affected by three tillage systems in Yellow Oxissol. The experimental design consists of a randomized block design, with split-plot (Soil Tillage systems X Depths samples) with 3 repetitions in two evaluation periods (2009 and 2012). The treatments consisted of three tillage systems, being Conventional Tillage (CT); No-Tillage (NT) and Reforestation with Paricá (RP). The two depths sampled were 0-0.1 m and 0.2-0.3 m. The attributes were evaluated as pH, organic matter, macronutrients levels, exchangeable acidity and micronutrient level. The soil tillage systems significantly affected the soil chemical attributes. In the NT system, the chemical attributes Ca, Mg, MO, P, K, Mn and Zn are concentrated on the most superficial layer of the soil, whereas in the CT there is a distribution of these variables along the topsoil.

“…According to Machado et al (2008), the water retention curve could directly affect the management and practices that should be used in agricultural systems. From the SWRC it is possible to determine the S index, developed by Dexter (2004aDexter ( , 2004bDexter ( , 2004c, that has been utilized as an indicator of the soils physical quality (Rosseti et al, 2013;Lima et al, 2014;Melo Filho et al, 2015). This indicator is based on the inflection point of the SWRC model proposed by van Genuchten (1980), having its values highly correlated with soil density, total porosity, macroporosity, and soil organic matter (Dexter, 2004a;Andrade & Stone, 2008;Silva et al, 2012;Cunha et al, 2011).…”

Soil Water Retention Curve and S Index as Soil Physical Quality Indicators for Integrated Production Systems

Assess the physical quality of agricultural soils it is important to establish the management more adequate for plant growth. In this study, the soil water retention curve and S index as indicators of soil physical quality were evaluated in five integrated production systems in the following forestry arrangements: Eucalyptus in a single line, double line and triple line (Eucalyptus I, II and III respectively), Balsa in triple line and Teak triple line. The density and arrangement of forest trees influence the soil physical properties. Less soil water retention was observed in the Teak and Balsa wood systems in the layers 0-0.10 and 0.10-0.20 m. The field capacity, permanent wilting point, and available water were lower under the projection from the treetops, providing less soil water retention at this site. This position suffers more influence of the animal's footstep, having greater alterations on the soil structure. Integrated production systems showed poor soil structural quality based on the S index, averaging 0.034 and 0.035 for layers 0-0.10 and 0.10-0.20 m respectively.
