Influence of Soil and Land‐Use/Land‐Cover Data Quality on SWAT Parameter Transferability in Small Subtropical Agricultural Watersheds

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
Does input soil and land‐use quality affect SWAT parameter transfer in neighbouring watersheds? Our proxy‐basin experiment in two small agricultural watersheds under crop–livestock rotations showed that capturing LULC dynamics and refining soil characterization can substantially enhance parameter transferability to ungauged neighbouring watersheds ...

Desenvolvimento de plantas de cobertura e produtividade da soja conforme atributos físicos em solo compactado Growth of cover crops and soybean yield according to physical attributes in compacted soil

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2012
Com a intensa utilização de tecnologias voltadas à mecanização das operações agrícolas, a compactação do solo é um fator que tem limitado a produtividade. Para atenuar este problema, o uso de plantas de cobertura do solo é frequentemente recomendado. Com

The Role of Two Glycoalkaloid Metabolism Genes in α‐Tomatine Biosynthesis and Basal Defence in Tomato

open access: yesMolecular Plant Pathology, Volume 27, Issue 6, June 2026.
We generated knockout mutants of two tomato genes proposed to be involved in α‐tomatine biosynthesis by genome editing. SlGAME2 mutants contained unaltered α‐tomatine contents; this gene is not involved in its synthesis. SlGAME4 mutants did not accumulate any glycoalkaloids but instead redirected resources towards steroidal saponin synthesis.

Enhancing soil health through no‐till, cover crops, and compost: A 5‐year field study

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract The capacity of soil management systems to conserve and promote soil health is crucial for its sustainability. While the effects of individual soil management practices on soil health receive considerable attention, their combined effects remain understudied. This paper presents the results of a 5‐year field experiment designed to evaluate the

Predictors of variation in the secondary metabolites of Usnea strigosa

open access: yes, 2023
The basic chemical composition of common lichens is often well known because it is required for the successful identification of lichen taxa; however, spatial and temporal variation in the suite of secondary metabolites produced by lichens is not well ...

Soybean growth and yield after single tillage and species mixture of cover plants

open access: yesRevista Ceres, 2012
The use of cover crops is important for the agricultural crop and soil management in order to improve the system and, consequently, to increase yield. Therefore, the present study analyzed the effect of crop residues of black oat (Avena strigosa Schreb.)

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

open access: yesNew 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 ...
