Ácido ascórbico como agente redutor para determinação de fósforo por colorimetria

open access: yesCiência Rural, 2014
Em muitos laboratórios de análises de solos, o ácido 1-Amino-2-naftol-4-sulfônico (ANS) é usado como agente redutor para determinação do P por espectrometria de UV/Visível.

Coinoculation of Bradyrhizobium and Azospirillum to Mitigate the Effects of Drought Stress in Soybean Plants

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Bacteria of the genus Azospirillum have been used to mitigate negative effects of drought stress. Since there is few information on interaction of new strains of A. brasilense and soil water status, we evaluated the effects of coinoculation of A. brasilense strains (Ab‐V5/Ab‐V6 and HM053) on soybean plants grown either with (40% of field capacity) or ...

Photosynthetic Traits Underlying Yield Differences in Irrigated and Rainfed Soybean Systems in the Mississippi Delta

open access: yesPlant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Understanding photosynthetic processes under field conditions is critical for identifying physiological determinants of seed yield (SY) in soybean. This study evaluated leaf gas exchange and chlorophyll fluorescence traits in seven soybean cultivars grown under irrigated (IR) and rainfed (RF) environments in the Mississippi Delta.

Fósforo disponível determinado por lâmina de resina enterrada Soil phosphorus availability determined by anionic-exchange resin membrane in the soil

open access: yesRevista Brasileira de Ciência do Solo, 2009
O uso de lâminas de resina de troca aniônica enterradas no solo permite simular, em parte, o comportamento das raízes das plantas em relação à absorção de P. Essa técnica, utilizada diretamente no solo nas mesmas condições que se cultivam as plantas, sem

Nematode Community Profiling in Organic and Conventional Spinach Systems

open access: yesPlant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Agricultural management practices play a significant role in shaping soil biological communities and ecosystem processes. Soil nematodes are valuable biological indicators of soil health because they occupy different trophic levels and are sensitive to alterations in environmental conditions.

Analyzing soil-available phosphorus by the Mehlich-3 extraction method to recommend a phosphorus fertilizer application rate for maize production in northern Mozambique

open access: yesPlant Production Science, 2019
The available phosphorus (P) in soil is a major limiting factor for maize productivity in the Nacala corridor, Mozambique. In this study, soils were collected from three representative sites, Ribaue, Nampula, and Nacala, in the area, and each was used ...

Soil pH thresholds mediate soil biodiversity by regulating interspecific associations in alpine wetlands of the Qinghai–Tibetan Plateau

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2392-2404, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil pH is recognized as a major determinant of soil biodiversity. However, the extent to which soil pH regulates soil biodiversity by influencing the biotic associations among species is unclear.

Soil properties and pH of the extractors influence extraction and availability P in alkaline soils from the São Francisco Valley, Brazil

open access: yesRevista Brasileira de Ciência do Solo
Phosphorus (P) is one of the most used nutrients in agriculture due to its high degree of interaction with the soil. It is susceptible to calcium precipitation in poorly weathered and alkaline soils, such as those in the Brazilian Semi-Arid region ...

Ensembling Crop Models and Multi Criteria Analysis to Unlock Bioenergy From Marginal Lands: A Scenario‐Based Assessment From Italy

open access: yesGCB Bioenergy, Volume 18, Issue 8, August 2026.
Multi‐Criteria Analysis to identify marginal land on which three crops (Safflower, castor bean, and Ethiopian mustard) were simulated with two process‐based models (DSSAT, ARMOSA) under two different agronomical management minimums (rainfed and no fertilization) and low input (half‐water and half‐nitrogen).
