Performance of Mehlich-1 and Mehlich-3 extractors in quantifying phosphorus in soils fertilized with liquid swine manure

Bioagro
Phosphorus is considered the most limiting essential macronutrient for plant production in soils of tropical climates. As the chemical and physical properties of the soil influence the availability of P to crops, the use of suitable extractants can increase the precision of the results obtained in soil analysis to enable the maximization of the ...

AVALIAÇÃO DA DISPONIBILIDADE DE FÓSFORO NO SOLO PARA O MILHO PELOS MÉTODOS MEHLICH-1 E MEHLICH-3

Scientia Agraria, 2009
Nos estudos de avaliação de metodologias de análise de solo, o fósforo tem sido o elemento mais estudado, fato este associado à complexidade da dinâmica do elemento no solo. A solução de Mehlich-1 vem sendo usada por muitos anos pelos laboratórios de análise de solo do Brasil, porém é um método que superestima a disponibilidade de fósforo no solo para ...

Disponibilidade de cobre para mudas de eucalipto em solos de cerrado

Revista Brasileira de Ciência do Solo, 2010
No Brasil, com a intensificação da silvicultura clonal, o plantio de materiais genéticos mais produtivos e exigentes nutricionalmente tem aumentado o aparecimento de sintomas de deficiência de micronutrientes, principalmente de B e, mais recentemente, de

Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1702-1714, September 2026.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...

Ácido ascórbico como agente redutor para determinação de fósforo por colorimetria

Ciência 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.

Dams and Their Legacies Shape Biogeochemical Evolution of Riparian Sediments

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Dams and their legacies have substantially altered riparian ecosystems worldwide and these effects could persist for decades or centuries into the future. However, how biogeochemical characteristics of riparian sediments evolve with depth and time post dam removal is poorly understood.

Establishment Limitations of Sensitive Target Species Potentilla alba L. in Grasslands Restored on Arable Land

Land Degradation &Development, Volume 37, Issue 14, Page 10053-10062, 30 August 2026.
ABSTRACT Species in grasslands restored from former arable land have multiple obstacles when establishing. Understanding whether these limitations stem from soil chemical or microbial differences could help to create suitable environments for specific target and other species with similar requirements.

Correlation and calibration of Mehlich‐3 sulfur for Kentucky bluegrass

Crop Science
Abstract Sulfur (S) is a crucial macronutrient for turfgrass growth, and declining atmospheric deposition has increased the risk of S deficiency. Reliable Mehlich‐3 soil test interpretations for S are lacking for turfgrass.

Bioavailable phosphorus across Florida’s diverse soil orders: implications for crop productivity and environmental protection

Frontiers in Environmental Science
Effective phosphorus (P) management is critical for sustainable agricultural production in Florida. The state’s diverse acid-mineral soils, including Alfisols, Entisols, Spodosols, and Ultisols, exhibit distinct physiochemical properties that profoundly ...

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

Revista 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
