1. SOIL PHYSICAL ATTRIBUTES BEFORE AND AFTER MANAGEMENT UNDER SOWING FORWARD SPEED
ABSTRACT The soil management system affects physical attributes, and the forward sowing speed can increase or decrease its results. Thus, this work aimed to evaluate management systems before and after soil mobilisation and forward sowing speed on soil physical attributes. Thus, an experiment was conduct in a completely randomized block design with four repl

2. Red-Yellow Latosol Penetration Resistance Under Different Subsoiling Depths
ABSTRACT The objective of this work was to evaluate the penetration resistance (PR) of a red-yellow latosol submitted to two subsoiling depths for implanting a forest plantation. The subsoiling was evaluated at 40 cm (S-40) and 50 cm (S-50) of depth by determining the soil moisture and soil density, while soil PR was evaluated before and after subsoiling at

3. Surface and incorporated liming effects on clay dispersion, water availability, and aeration capacity of a Dystrudept soil
ABSTRACT Liming represents a management procedure that can affect the soil structure and its thermodynamic processes. In this context, the aims of this study were to assess (i) the effects of the surface and incorporated liming on the clay dispersion, soil water availability, and aeration capacity; (ii) the influence of soil chemical alterations in its physi

4. Soil Physical Quality and Soybean Yield as Affected by Chiseling and Subsoiling of a No-Till Soil
ABSTRACT The concept of soil physical quality (SPQ) is currently under discussion, and an agreement about which soil physical properties should be included in the SPQ characterization has not been reached. The objectives of this study were to evaluate the ability of SPQ indicators based on static and dynamic soil properties to assess the effects of two loose

6. Influencia da subsolagem e da adubacao organica na produtividade e na composicao quimica da raspa e do feno da mandioca.
Com o objetivo de estudar a influencia do preparo do solo sobre a produtividade e a composicao quimica da raspa e do feno da parte aerea da mandioca, utilizou-se a subsolagem com e sem a adicao de esterco. O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial em faixa. A colheita da parte aerea e da raiz foi realizada sete meses

7. ANÃLISE TÃCNICO-ECONÃMICA DA RECUPERAÃÃO DE UM SOLO SÃDICO NO PERÃMETRO IRRIGADO CURU-PENTECOSTE-CE / Techno-economical analysis of the reclamation of a sodic soil in the Irrigated Perimeter Curu-Pentecoste-CE.
In the semi-arid part of Northeastern Brazil, the highest incidences of salinized areas are observed in land subjected to intense irrigated cultivation, in the âPerÃmetros Irrigadosâ (irrigated perimeters), particularly those where is used the surface method. The experiment was performed in the âNÃcleo Dâ (D Core) of the âPerÃmetro Irrigado Curu-Pent

8. Hydric erosion and initial development of the Eucalyptus grandis in a Red-Yellow Argisol submitted to different methods of soil preparation in the Vale do Paraíba-SP region / Erosão hídrica e desenvolvimento inicial do Eucalyptus grandis em um Argissolo Vermelho-Amarelo submetido a diferentes métodos de preparo de solo no Vale do Paraíba - SP
In Brazil, and especially in the state of São Paulo in the Vale do Paraíba region, eucalypt plantation is expanding to high declivity areas occupied with degraded pastures due to the limited agricultural value of these topographies and its greatest forest aptitude. Such areas are naturally more susceptible to the hydric erosion, which reduces the fores

9. Operational performance of a subsoiler as a function of the structure, clay and moisture content in three latosols. / Desempenho operacional de um subsolador em função da estrutura, do teor de argila e de água em três latossolos.
A rápida evolução tecnológica da silvicultura brasileira, verificada na década de 80, culminou com o sistema de cultivo mínimo do solo, implantado em grande escala a partir do início da década de 90. Levantamentos recentes junto a empresas florestadoras de expressão nacional, indicaram que cerca de 77% da área plantada é realizada no sistema de cu
