Structural Quality of an Ultisol Under Long‐Term Different Tillage Systems and Cover Crops With Corn in Northeast Brazil

Soil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Dual‐purpose corn cropping is a widespread and economically important agricultural activity in Brazilian rural areas. The objective of this work was to study the structural quality of a dystrophic Red‐Yellow Ultisol under different tillage systems, previous crops and inoculant treatments, and its relationship with corn yield.

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.
