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.

Nickel Effects on Growth and Phytolith Yield of Grasses in Contaminated Soils

Soil Systems
Nickel (Ni) is extremely toxic to plants at high concentrations. Phytoliths have the potential to sequester the heavy metals absorbed by plants and act as a detoxification mechanism for the plant.

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 texture prevails over vegetation change in determining soil organic carbon storage in an African savanna

Journal of Ecology, Volume 114, Issue 4, April 2026.
We compared soil organic carbon (SOC) across six savanna–forest boundaries in South Africa. Surprisingly, savanna and forest soils contained comparable SOC stocks. While vegetation change shifted the carbon source from C4‐grasses to C3‐trees, total carbon storage was driven by local soil texture (clay/silt), proving that increasing tree cover does not ...

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...
