Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Reducing Nitrogen Fertilizer Dependency in Tropical Pastures Through Azospirillum Brasilense and Pseudomonas Fluorescens Coinoculation

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Coinoculation with Azospirillum brasilense and Pseudomonas fluorescens was associated with maintained forage productivity under reduced nitrogen (N) fertilizer rates in tropical pastures. This hypothesis was evaluated in a 2‐year field experiment conducted over two consecutive growing seasons (2022 and 2023) the State University of Goiás, São Luís de ...

The synergy between zinc and vitamins promotes corn growth and yield

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Using zinc and vitamins can help improve the physiological conditions of corn (Zea mays L.), providing better vegetative and reproductive development. Because of their potential for use in agriculture, an attempt is being made to establish the most efficient utilization. This study evaluated the effects of zinc, nicotinamide, and pyridoxine on

Degradation and Restoration of Anthrosols in the Amazonia Under Contrasting Agricultural Practices: Evidence From the Assessment of Soil Physical Quality and Carbon and Nitrogen Stocks

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT This study was conducted to assess the impact of different agricultural practices on the physical quality and the carbon and nitrogen stocks of anthropogenic soils used by smallholder farmers in Central Amazonia, Brazil. Undisturbed and disturbed soil samples were collected at three depths (0–0.10 m, 0.10–0.20 m, and 0.20–0.30 m), with five ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

Phosphogypsum Doses and Subsoil Contamination: A Study on the Mobility of Rare Earth Elements, Uranium, and Thorium

European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.
Experiment setup view. ABSTRACT Soil conditioners are commonly used by producers aiming to enhance agricultural productivity, and among these products, phosphogypsum has gained increasing attention. As an agricultural amendment, phosphogypsum contains rare earth elements (REE), uranium (U), and thorium (Th), raising environmental concerns regarding its
