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.

Disponibilidade de cobre para mudas de eucalipto em solos de cerrado
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

Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches
Abstract While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use. We evaluated the potential of non‐radioisotopic approaches to estimating net Pmin by difference before and after aerobic incubation, analogous ...

Ácido ascórbico como agente redutor para determinação de fósforo por colorimetria
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.

Abstract Commercial row crop production in the midsouthern United States is characterized by extensive application of inorganic soil inputs and management practices that contribute to degraded soil health. This study was conducted to determine if cover crops affect spatial or temporal changes in soil chemical properties in a raised, stale seedbed ...

Corn response to broiler litter total cleanout frequency
Abstract Broiler (Gallus gallus domesticus) litter is a valuable nutrient source for corn (Zea mays L.) production in the southeastern United States; however, differences in total cleanout frequency of broiler houses may influence the agronomic value of broiler litter. A 3‐year field study was established on Decatur silt loam and Malbis sandy clay loam

Interpreting results of the Mehlich-3 ICP Soil Phosphorus Test [PDF]
Iowa State University (ISU) has provided soil-test interpretations for the Bray-1, Olsen, and Mehlich-3 (M3) soil phosphorus (P) tests since 1996. These tests use a colorimetric analysis method to measure the P extracted from the soil.
