Physical quality of an oxisol under different uses [PDF]

Revista Brasileira de Ciência do Solo, 2012
The use of a soil induces changes in the physical properties according to the management, tillage intensity and type of crop. The objective of this work was to measure the alterations of some of the soil physical properties and evaluate the physical quality by the S index, an indicator proposed by Dexter (2004), comparing the land uses: eucalyptus ...

Weed Management Influences the Accumulation of Organic Matter in the Soil and Productivity in Coffee Farming

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
The management of weeds can influence organic matter (OM) and organic carbon (OC) levels, impacting the productivity and sustainability of coffee plantations. This study aimed to evaluate OM and OC levels in coffee soils under different weed management practices and their influence on coffee tree physiology and productivity. The experiment featured six

Dispersão de argila em microagregados de solo incubado com calcário Clay dispersion in microaggregates of soil incubated with limestone

Revista Brasileira de Ciência do Solo, 2008
A compactação do solo restringe o rendimento de culturas de grãos. Dentre outros fatores, a calagem pode favorecer a dispersão de microagregados e a formação de camadas compactadas.

Nitrogen dynamics in soils cultivated with maize and fertilized with pig slurry. [PDF]

, 2017
The proper disposal of pig manure is of great importance because, when mishandled, it can contaminate water resources. This study aimed to evaluate the nitrogen dynamics in a Cerrado Oxisol and its absorption, over time, by a maize crop managed with pig ...

Sustaining Cocoa Production on Oxisols in Malaysia [PDF]

, 2015
Oxisols are dominated by variable charge minerals in their clay fraction, containing an insufficient amount of Ca and Mg in their soil solutions. Under natural conditions, cocoa grown on the soils is subjected to the stress of low pH and Al and/or Mn toxicity, which eventually produces low yields.

Biochar Mitigates Arsenic Phytotoxicity and Improves Crop Performance in Iron‐Rich Tropical Soils

Plant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT The contamination of tropical soils by the highly toxic metalloid, arsenic (As), is a pervasive issue, resulting in declining crop performance due to phytotoxicity. Biochars are gaining popularity as sorbents for contaminants, yet their capacity to ameliorate As phytotoxicity in diverse tropical soil types remains underexplored.

Least limiting water range and degree of compactness of soils under no- tillage

Bioscience Journal, 2015
The least limiting water range (LLWR) and degree of compactness (DC) can be useful indicators of soil physical quality and crop yield. This study focused on assessing of LLWR, DC and evaluation of critical values to crop growth of an Alfisol and Oxisol ...

Organic residues and Parachlorella microalgae favor the growth and gas exchange of cedar [PDF]

Scientia Agricola
Using organic residues and bioinputs is a promising and sustainable practice to produce seedlings with forest essences, such as Cedrela fissilis Vell. (cedar), a vulnerable species close to extinction due to intensive exploitation in native areas.

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Soil-atmosphere exchange of nitrous oxide, nitric oxide, methane, and carbon dioxide in logged and undisturbed forest in the Tapajos National Forest, Brazil. [PDF]

, 2016
Selective logging is an extensive land use in the Brazilian Amazon region. The soil?atmosphere fluxes of nitrous oxide (N2O), nitric oxide (NO), methane (CH4), and carbon dioxide (CO2) are studied on two soil types (clay Oxisol and sandy loam Ultisol ...
