Land‐Use Change Enhances Organic Phosphorus Pools in Oxisols in Brazil's New Agricultural Frontier

Soil Use and Management, Volume 41, Issue 3, July‐September 2025.
ABSTRACT Land‐use types and management systems can affect the availability of phosphorus (P) by modifying its compartments. The aim of this study was to evaluate the organic and inorganic fractions of P in an Oxisol in the Cerrado region of Brazil, considering various land‐use types and management systems and the period of application.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different

Diazotrophs Show Signs of Restoration in Amazon Rain Forest Soils with Ecosystem Rehabilitation. [PDF]

, 2020
Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO2 sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However,

Sewage sludge-based organomineral fertilizer improves phosphorus efficiency in Urochloa brizantha

Revista Brasileira de Ciência do Solo
ABSTRACT Sewage sludge (SS) from wastewater treatment has reasonable phosphorus (P) levels, which could be used as fertilizer in agriculture. However, SS-P content is lower than mineral fertilizers, which limits its operational application.

Community‐Level Metabolic Shifts Following Land Use Change in the Amazon Rainforest Identified by a Supervised Machine Leaning Approach

Environmental Microbiology Reports, Volume 17, Issue 2, April 2025.
A machine learning (ML)‐derived metagenomic analysis of soils collected from Amazon forests and long‐term established pastures showed different microbial community strategies towards carbohydrate metabolism and energy allocation. The ML approach allowed the development of metabolic maps that explained process‐level modifications to the C and N ...
