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

GCB 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).

End‐of‐season corn stalk analysis as a tool to fine‐tune potassium and nitrogen management

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Corn (Zea mays L.) requires proper nutrient management for optimal growth, and tissue testing plays an important role in refining recommendations. Corn stalk nitrate test (CSNT) is used to evaluate nitrogen (N) management; however, a comparable plant‐based diagnostic tool for potassium (K) is lacking. This study evaluated extractants for stalk‐

Determining Mehlich‐3 and DTPA extractable soil zinc optimum economic threshold for maize

Soil Use and Management, 2020
Abstract Maize ( Zea mays L.) is one of the most susceptible crops to zinc (Zn) deficiency. However, in much of the world, soil Zn tests are poorly calibrated, and thus determining a critical soil test, level for Zn is challenging.

Soil sample timing and depth effect on soil health assessment in Mid‐South US row‐crop production systems

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Spatial and seasonal variability in soil properties influences soil analysis results, but their impact on soil health assessment has not been well investigated. We evaluated how soil health indicators and scores were affected by soil sampling time (spring, summer, fall, and winter) and depth (0–5, 5–10, and 10–15 cm).

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

Why raw yield data are better than relative yield in informing agronomic and economic decisions

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract While relative yield is widely used for its comparability, normalization can cause significant information loss. This study reframes yield metric selection as a model evaluation problem to determine the most accurate representation of crop response. We evaluated seven yield metrics with three agronomic models, comparing estimates of a critical

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 ...

Nitrogen fertilization rates to maximize winter malting barley yield while meeting protein requirements in Ohio

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Due to the craft beer industry, there is an emerging need for winter malting barley (Hordeum vulgare L.) nitrogen (N) rate recommendations in Ohio. An experiment was conducted at seven site‐years to identify the optimum spring N application rate to maximize barley grain yield while maintaining protein requirements for malting.

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.
