INFLUÊNCIA DA COMPACTAÇÃO E DO CULTIVO DE SOJA NOS ATRIBUTOS FÍSICOS E NA CONDUTIVIDADE HIDRÁULICA EM LATOSSOLO VERMELHO   Amauri Nelson BeutlerJosé Frederico CenturionCassiano Garcia RoqueZigomar Menezes de SouzaDepartamento de Solos e Adubos, Faculdade de Ciências Agrárias e Veterinárias, Universidade Estadual Paulista, Jaboticabal, SP.

E-mail: [email protected], [email protected]  1 RESUMO              Este estudo teve como objetivo determinar a influência da compactação e do cultivo de soja nos atributos físicos e na condutividade hidráulica de um Latossolo Vermelho de textura média. O experimento foi conduzido na Universidade Estadual Paulista – Faculdade de Ciências Agrárias e Veterinárias, Jaboticabal (SP). Os tratamentos foram: 0, 1, 2, 4 e 6 passadas de um trator, uma ao lado da outra perfazendo toda a superfície do solo, com quatro repetições. O delineamento experimental foi inteiramente casualizado para a condutividade hidráulica e, em esquema fatorial 5 x 2 para os atributos físicos. Foram coletadas amostras de solo nas faixas de profundidades de 0,02-0,05; 0,07-0,10 e 0,15-0,18 m, por ocasião da semeadura e após a colheita para determinação da densidade do solo, porosidade total, macro e microporosidade do solo. A condutividade hidráulica do solo foi determinada após a colheita. O tempo entre a semeadura e a colheita de soja foi suficiente para aumentar a compactação do solo apenas na condição de solo solto. A compactação do solo reduziu a condutividade hidráulica em relação a condição natural (mata) e a condição de solo solto, sendo que esta não foi reduzida, após a primeira passagem, com o aumento no número de passagens.  UNITERMOS: Densidade do solo, porosidade do solo, infiltração de água, soja.  BEUTLER, A.

COMPACTION AND SOYBEAN GROW INFLUENCE ON PHYSICAL ATTRIBUTES AND  HYDRAULIC CONDUCTIVITY IN RED LATOSSOL SOIL   2 ABSTRACT  The purpose of this study was to determine the influence of compaction and soybean grow on physical attributes and hydraulic conductivity of a Red Latossol, medium texture soil. The experiment was carried out in the experimental farm at the Paulista State University  – Agricultural Science College, Jaboticabal – São Paulo state. The treatments were 0, 1, 2, 4 and 6 side-by-side tractor strides on the soil surface with four replications. The experimental design was completely randomized for hydraulic conductivity and a 5 x 2 factorial design for soil physical attributes. Soil samples have been collected at 0.02-0.05, 0.07-0.10 and 0.15-0.18 m depth at sowing season and after harvest in order to determine soil bulk density, total porosity, macro and micro porosity. Soil hydraulic conductivity was determined after harvest. The time period between the soybean sowing and harvesting was enough to increase soil compaction only in loose soil condition. Soil compaction reduced hydraulic conductivity compared to the natural (forest) and loose soil condition  KEYWORDS: Bulk density, soil porosity, water infiltration, soybean.

Physical And Chemical

The objective of this work was to evaluate the correlation between sugarcane yield and some physical and chemical attributes of soil. For this, a 42‑ha test area in Araras, SP, Brazil, was used. Soil properties were determined from samples collected at the beginning of the 2003/2004 harvest season, using a regular 100x100 m grid. Yield assessment was done with a yield monitor (Simprocana). Correlation analyses were performed between sugarcane yield and the following soil properties: pH, pH CaCl2, N, C, cone index, clay content, soil organic matter, P, K, Ca, Mg, H+AL, cation exchange capacity, and base saturation. Correlation coefficients were respectively ‑0.05, ‑0.29, 0.33, 0.41, ‑0.27, 0.22, 0.44, ‑0.24, trace, ‑0.06, 0.01, 0.32, 0.14, and 0.04. Correlations of chemical and physical attributes of soil with sugarcane yield are weak, and, per se, they are not able to explain sugarcane yield variation, which suggests that other variables, besides soil attributes, should be analysed.

Over Time

The substitution of native vegetation in agricultural systems can cause several changes in the chemical and physical soil attributes, and in the dynamics of soil organic carbon. This study aimed to evaluate changes in soil physical attributes and carbon stock in soil organic matter fractions in irrigated sugarcane crops, as a function of land use and straw management practices over time, in the North of Minas Gerais State, Brazil. Four sugarcane fields with different ages and management systems were studied: Cane 6, Cane 7, Cane 8, and Cane 10. The data obtained were compared with a native vegetation area located near the sugarcane fields, and used as reference for unmanaged soil. In each system, soil samples were collected in the 0-10, 10-20, and 20-30 cm depth layers, to determine the physical attributes, the total organic carbon, and the physical fractions of the soil organic matter. We found that the sugarcane management with the maintenance of a part of the straw on the soil surface contributes to the preservation of the soil structure and the most stable fractions of organic carbon over time. However, in the regions with high annual mean temperature and in the irrigated systems, the soil tillage for the renewal of the sugarcane fields significantly decreases the total soil organic carbon.
