13. SOIL PHYSICAL AND BIOLOGICAL CHARACTERIZATION AFTER HERBICIDES APPLICATION IN BLACK WATTLE (Acacia mearnsii De Wild.) STANDS IN RIO GRANDE DO SUL / CARACTERIZAÇÃO FÍSICA E BIOLÓGICA DO SOLO APÓS APLICAÇÃO DE HERBICIDAS EM PLANTIOS DE ACÁCIA-NEGRA (Acacia mearnsii De Wild.) NO RIO GRANDE DO SUL
The study of soil quality biological indicators in areas classified as forest production units is important to understand the ecological processes that occur in these systems. Monitoring the soil fauna in modified environments, when management practices involve chemical products in the environment, is an instrument that allows to evaluate not only the soil q

14. Nitrogen, phosphorus and potassium recommendation for sunflower under no-tillage system in Paraguay / RECOMENDAÇÃO DE NITROGÊNIO, FÓSFORO E POTÁSSIO PARA GIRASSOL SOB SISTEMA PLANTIO DIRETO NO PARAGUAI.
Sunflower crop has some important agronomic characteristics, as great fitomassa production, larger resistance to the drought, cold and heat than most of the cultivated species and wide adaptability to different conditions of soil and climates. Its deep root system provides absorption of nutrients of the deepest layers, ciclying great amounts of nitrogen (N),

15. Atributos quÃmicos de um latossolo vermelho eutrofÃrrico submetido a gessagem e cultivado com trigo e soja em semeadura direta / Change chemical âlatossolo vermelho eutrofÃrricoâ submitted gypsum with soy and wheat no-tillage
The presence of aluminum in the soil is one among the several existent problems that harm the growth, development and productivity in commercial cultures as soy and wheat principally when water deficit, once there is minor surface of roots for the absorption of water. Like this the influence of the use of the plaster was analyzed in the chemical characterist

16. Dinâmica do fósforo em latossolo do cerrado sob sistema de integração lavoura-pecuária
The integration of crop-livestock systems (ILP) is one of the alternatives to recover the fertility of soils under degraded pastures in the Cerrado region. This system has positive effects on soil fertility and quality, increasing organic carbon contents and soil biological activity, thus requiring a new characterization of soil fertility by identifying soil

17. Seqüestro de carbono e alterações bioquímicas da matéria orgânica de solos cultivados com eucalipto / Carbon sequestration and biochemical changes in organic matter of soils cultivated with eucalyptus
The maintenance of soil organic matter (SOM) in commercial plantations of eucalyptus depends on the adoption of appropriate crop and soil management. Changes in inventories of C and the quality of the MOS caused by the use and soil management can be identified by quantifying the stocks of C in forest compartments (soil and plant) over time of cultivation, an

18. Desenvolvimento de mudas de cafeeiro cultivadas em tubetes e submetidas a diferentes níveis de déficit hídrico / Development of coffee seedlings cultivated in plastic tubes and submitted at different levels of hydric deficit
Coffee production is a very important activity in the socioeconomic context in Brazil, which makes billion of dollars go around the economy every year generating thousands of direct and indirect jobs. The success in the coffee production depends on the observation of several needs, among others the choice of healthy and vigorous seedlings with good genetic p

19. Análise de crescimento e produtividade de duas variedades de cana-de-açúcar (Saccharum spp) influenciadas por doses de fósforo
The knowledge of the leaf area is required every time the sugarcane is subjected to evaluation in which different varieties are compared or submitted to different environmental conditions, managements or fertilizations, therefore evidently showing alteration in dimensions of the plant leaves, so affecting the photosynthetic process. Although the higher breat

20. Efeito da umidade do solo e carga aplicada pela roda compactadora no ambiente solo-semente em sistema de plantio direto na cultura da soja / Effect of water content and load applied by the press wheel on the soil-seed environment in the soybean direct planting system
The soils physical conditioning around the seeds is important to the initial cultivation development and to assure an adequate plant population. An appropriate soil-seed contact is required to a rapid emergence and a good effectiveness of cultivation. The present work aimed to study the effects of the combination between the soil water contents of the soil a

21. Avaliação comparativa do processo de ocupação e degradação das terras das microbacias hidrográficas dos ribeirões Três Bocas e Apertados no Norte do Paraná
A dinâmica urbana e rural da região Norte do Paraná, se caracterizou por intensas transformações nas últimas décadas, pela energia construtiva dos imigrantes, pelo papel do Estado, pelos tipos de solo, relevo e clima. A rapidez com que se deram essas modificações conduziu ao aumento da produção agrícola num curto prazo, apresentando, no entanto,

22. PROPRIEDADES MECÂNICAS DE SOLO FRANCO ARENOSO SOB DISTINTOS SISTEMAS DE PREPARO, TRÁFEGO MECANIZADO E RESÍDUOS VEGETAIS / MECHANICAL PROPERTIES OF A SANDY LOAM SOIL AFFECTED BY TILLAGE STEMS MECHANICAL TRAFFIC AND SURFACE MULCH
The excessive mobilization of the soil causes losses to its structure. This is eliminated with the no tillage system, where mobilization only occurs in the planting line. However, considering that lately there was an increase in the use of the agricultural soils and of the mechanization, compaction problem in the surface soil layer in the system of no tillag

23. Productivity of maize âsafrinhaâ by direct planting system as a function of covering species and surface application of calcium / Produtividade do milho âsafrinhaâ em sistema plantio direto em funÃÃo da utilizaÃÃo de espÃcies de cobertura e aplicaÃÃo de calcÃrio em superfÃcie
The present work had for objective to evaluate the effect of different covering crops and the surface liming in no-tillage system, determining the content of dry biomass produced by each one of these species and the effect of the liming on the chemical properties of the soil and its consequent effect in the yield components and the productivity of the winter

24. ADUBAÃÃO NITROGENADA, DENSIDADE DE SEMEADURA E ESPAÃAMENTO ENTRE FILEIRAS NA CULTURA DO MILHO EM SISTEMA PLANTIO DIRETO. / Nitrogen fertilization, sowing rate and interrow spacing in corn crop in no-tillage system.
Entre as prÃticas e tÃcnicas empregadas para obtenÃÃo de maior produtividade de milho, a escolha do arranjamento de plantas e a Ãpoca de aplicaÃÃo da cobertura nitrogenada estÃo entre as decisÃes mais importantes, associados a escolha do hÃbrido e o sistema de cultivo. Deste modo, vÃrios trabalhos tem sido realizados no Brasil visando esclarecer e
