Environmental conditions affect crop yield, and water deficit has been highlighted by the negative impact on soybean grain production. Radicial growth in greater volume and depth can be an alternative to minimize losses caused by a lack of water. Therefore, knowledge of how soybean roots behave before the chemical, physical, and biological attributes of the soil can help establish managements that benefit in-depth root growth. The objective was to evaluate the growth of soybean roots in response to chemical, physical, and biological variations in the soil, in different soil locations and depths. Six experiments were conducted in different locations. Soil samples were collected every 5 cm of soil up to 60 cm of soil depth for chemical, physical, and biological analysis. The roots were collected every 5 cm deep up to 45 cm deep from the ground. The six sites presented unsatisfactory values of pH and organic matter, and resented phosphorus, potassium, and calcium at high concentrations in the first centimeters of soil depth. The total porosity of the soil was above 0.50 m3 m−3 , but the proportion of the volume of macropores, micropores, and cryptopores resulted in soils with resistance to penetration to the roots. Microbial biomass was higher on the soil surface when compared to deeper soil layers, however, the metabolic quotient was higher in soil depth, showing that microorganisms in depth have low ability to incorporate carbon into microbial biomass. Root growth occurred in a greater proportion in the first centimeters of soil-depth, possibly because the soil attributes that favor the root growth is concentrated on the soil surface.

Parâmetros bioquímicos de plantas de pimenta longa, em cultivos com e sem suplementação hídrica, foram estudados em condições de campo, no período de maio/98 a março/99, no município de Igarapé-Açu, PA. Adotaram-se os seguintes tratamentos: T1 - irrigado e não-adubado; T2 - irrigado e adubado; T3 - não-irrigado e não-adubado; T4 - não-irrigado e adubado. Avaliou-se o efeito do estresse hídrico, através do conteúdo de clorofila, dos teores de açúcares solúveis e proteínas totais, e dos teores de fósforo e potássio. Observou-se que, nos meses mais secos, ocorreu a redução do conteúdo de clorofila, independente do tratamento aplicado, sendo a clorofila a, a mais afetada. O estresse hídrico reduziu os teores de açúcares solúveis totais e de potássio, enquanto os de proteínas e fósforo se mantiveram constantes, durante o período de observação. Nas plantas irrigadas, os teores de potássio aumentaram com a idade. |
