Adsorção de íons Cu2+ em latossolo vermelho-amarelo húmico

Química Nova, 2000
In environmental studies it is necessary to know the adsorption behavior of metals by soils, since the unfavorable effects of heavy metals and even the micronutrients at high concentrations in the environment are related to these adsorbents' ability to ...

Adsorption and availability of phosphorus in response to humic acid rates in soils limed with CaCO3 or MgCO3

Ciência e Agrotecnologia
Humic acid (HA) may reduce adsorption and increase soil P availability, however, the magnitude of this effect is different when Ca2+ prevails over Mg2+ in limed soils.

Using root water uptake estimated by a hydrological model to evaluate the least limiting water range [PDF]

Revista Brasileira de Ciência do Solo
The least limiting water range (LLWR) has been extensively determined, but evaluating if LLWR can indeed indicate soil physical stress on plant growth is still a controversial issue.

Cultivation systems using vegetation cover Improves Sustainable Production and Nutritional Quality of New Rice for Africa in the Tropics

Rice Science, 2018
Little is known about the impact of direct sowing under vegetation cover on the production and quality of New Rice for Africa (NERICA) on poor oxisol. In this study, two NERICA varieties (NERICA 3 and NERICA 8) were grown under tropical oxisol soil with ...

Impact of fertirrigation with swine wastewater in an oxisol

Vértices, 2013
O objetivo do trabalho foi avaliar o efeito da aplicação de Água Residuária de Suínos (ARS) sobre as propriedades químicas e físicas de um Latossolo Vermelho-Amarelo distrófico. O experimento foi realizado em condições de campo, com os seguintes tratamentos: T1 = 0; T2 = 50; T3 = 100; T4 = 150 m3.ha.ano-1 de ARS.
