1. Carbon indices to assess quality of management systems in a Subtropical Acrisol
ABSTRACT: Management systems to improve soil quality are essential for agricultural and environmental sustainability. We assessed the quality of soil management systems applied to a subtropical Acrisol in terms of the carbon management index (CMI), the stratification ratio for total organic carbon (SR-TOC) and light fraction of organic matter (SR-LF). In add

2. Fertilización nitrogenada después de la poda del cafeto robusta en Cambisoles
The objective of this work was to evaluate the influence of nitrogen mineral fertilization, after robusta coffee pruning, on crop yield and some chemical (pH, organic matter) and microbiological (biological gas exchange and nitrification) soil indicators in two Cambisols in Tercer Frente, Santiago de Cuba, and La Alcarraza, Holguín, during the years 2003-20

3. Produção e qualidade biológica e química de diferentes vermicompostos para a produção de cenouras rumo à sustentabilidade dos agroecossistemas / Production and biological and chemical quality of different vermicomposts for the carrots production forward to a sustainability of agroecosystems.
The objective of this work was to evaluate the biological and chemical quality of the different vermicomposted residues and its used as basic fertilization for the carrots production. The trial was divided in two stages: 1st) vermicomposting of the different organic residue and its biological and chemical assessment and 2nd) evaluation of the vermicomposts a

4. Utilização de matéria orgânica no controle de nematóide das galhas em alface sob cultivo protegido
This research was carried out aiming to evaluate the effect of organic manure in the control of root-knot nematodes in lettuce cv. Verônica. Organic cattle and chicken manure were evaluated; they are both used for vegetable production in the region. The experiment was carried out at Estação Experimental de Biologia, University of Brasilia, from July to No

5. Application of vinasse in soils: effect on soil charges and particle dispersion / AplicaÃÃo de vinhaÃa em solos: efeito no balanÃo de cargas e dispersÃo de partÃculas
The vinasse is the main byproduct of the ethanol and sugarcane brand production; these activities are in large expansion in Brazil. For a long time the vinasse was launched into water courses, generating negative environmental impacts. One of the alternatives for producers to get rid of vinasse is its addition in soils as fertilizer. Although the effects of

6. CRESCIMENTO, ESTADO NUTRICIONAL E CARACTERÍSTICAS FOTOSSINTÉTICAS DE Bertholletia excelsa SOB TRATAMENTOS DE ADUBAÇÃO EM ÁREA DEGRADADA NA AMAZÔNIA CENTRAL
Human activities on forest ecosystems can result in the removal of forest cover followed by impoverishment of the soil physical, chemical and biological properties. Throughout time, these areas without forest coverage can turn in to degraded areas. In face of this, for the revegetation of these areas with forest species different methods have been applied fo

7. Organic fertilization and green manure managenent on chemical and biological soil properties and on lettuce growth in organic system / AdubaÃÃes orgÃnicas e manejo de adubo verde nos atributos quÃmicos e biolÃgicos do solo e na cultura da alface em sistema de cultivo orgÃnico
Em funÃÃo da carÃncia de informaÃÃes tÃcnicas sobre adubaÃÃo da cultura da alface (Lactuca sativa L.), em sistema de cultivo orgÃnico, este trabalho teve o objetivo de estudar prÃticas mais convenientes de adubaÃÃo que auxiliem na manutenÃÃo da fertilidade do solo e produtividade da cultura. O delineamento experimental foi o de blocos ao acaso

8. Prácticas culturales para el manejo de la Sigatoka negra en bananos y plátanos
Black sigatoka (Mycosphaerella fijiensis) control consists in the continuous use of fungicide sprays and cultural practices. Cultural control reduces inoculum sources of the pathogen and favorable environmental conditions for its development, as well as it increases the vigor of the plants. In order to manage the disease it is necessary to know its behavior

9. 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

10. Atributos químicos e físicos do solo influenciados pela aplicação de dejetos suínos em lavoura sob plantio direto
The increase in the confined swine production has generated great volume of slurries, being in general applied on the soil as fertilizers. Thus, fertilizations in excess and, or, continued with this residue will be able to cause environmental impacts undesirable, being distinguished the soil chemical, physical and biological disequilibria, pollution of water

11. Aplicação foliar de nitrato e de microorganismos eficazes (EM) e seus efeitos sobre a partição de nutrientes em variedades de milho (Zea mays L.) cultivadas com resíduo industrial / Nitrate and effective microorganisms (EM) foliate application and the effects on the nutrient partition in corn varieties (Zea mays L.) cultivated with industrial residue
Nitrate and the microorganism solution (EM), in different treatments, were applied to the foliage of the Sol da manhã and BRS 1010 corn varieties, in order to evaluate nutrients level in different parts of the plants (vegetative and reproductive). It was also evaluated the possibility of the usage of an industrial residue, generated from the production of l

12. Rehabilitation potential of a mine spoil trhough revegetation and microbial management. / Potencial de reabilitação do solo de uma área degradada, através da revegetação e do manejo microbiano.
The increasing degraded soil areas caused by open cast mining activities has brought critical damages to the environment. The mine spoil must be ameliorated with anthropogenic interferences, consisting of revegetating soils, introducing organic matter and microbial diversity, basic conditions for a sustainable soil biological activity. The objective of this
