1. Qualidade físico-hídrica de um argissolo vermelho-amarelo sob agroecossistema e floresta natural em Roraima
Na Amazônia, a conversão da floresta natural em pastagens e outros sistemas de produção têm provocado modificações físico-hídricas dos solos em função do tipo de uso e sistemas de manejo. A avaliação dessas modificações por meio de atributos físicos se torna imprescindível para a mensuração da qualidade física dos solos, sendo úteis para

2. PARÂMETROS FÍSICO-HÍDRICOS DE UM LATOSSOLO SOB DIFERENTES SISTEMAS DE MANEJO E NÍVEIS DE TRÁFEGO / PHYSICOHYDRICAL SOIL PARAMETERS OF AN OXISOL UNDER DIFFERENT SOIL MANAGEMENTS AND TRAFFIC LEVELS
Soil quality has been widely studied since the soil is recognized as a key resource in agricultural production. Thus, it is necessary to assess a range of indicators of soil quality, in order to monitor parameters that indicate quality or soil degradation in agricultural activities. The objective was to assess indicators of physical and hydrical soil quality

3. QUALIDADE FÍSICO-HÍDRICA DE UM ARGISSOLO SOB FLORESTA E PASTAGEM NO SUL DO BRASIL / PHYSICO-HYDRIC QUALITY OF A HAPLUDALF UNDER FOREST AND PASTURE IN SOUTH BRAZIL
Soil compaction is a problem in different production systems: agriculture, pasture and forest. In the agriculture soil compaction is well documented, while in the pasture and forest its study is scarce. The objective of this study was to evaluate the physical-hydric quality of an Alfisol under forest and pasture in South Brazil, and stabilish parameters and

4. Variabilidade espacial da qualidade físico-hídrica do solo de um sistema em produção agroecológica. / Spatial variability of physical - hydric soil quality of an agroecological production system
The knowledge of physical hydric soil quality indicators is crucial during planning and management of agriculture activities. Many articles had been written to identify and to correlate the physical hydric soil quality and crop production. However, the most part of the results are not reliable for mapping spatial variability, mainly in large areas. The objec

5. Efeitos da fertirrigaÃÃo com efluente de lagoa de polimento nos atributos do solo e na produÃÃo de feijÃo caupi (Vigna unguiculata (L.) Walp)
This work aimed to investigate, through an experiment under field conditions, the chemical and physico-hydrical alterations of a typical Argissolo Amarelo EutrÃfico, and the production components of the cowpea bean (Vigna unguiculata (L.) Walp), in response to the fertigation management with secondary effluent (ME) originated from domestic source, comparing
