Effects of Feeding Phytase Enzyme and HAP Corn on Solubility of Phosphorus, Copper, and Zinc in Turkey Manure and Manure-Amended Soils
… Zn were extracted with 0.01 M CaCl₂ and acidic Mehlich III extractant (Zn in soil extracts was not evaluated). Dietary treatments were (1) normal phytic acid (NPA) corn and 0.135% inorganic P (NPA diet); (2) NPA corn, 600 units phytase enzyme, and 0.135% inorganic P (NPA+Phyt diet); (3) High …

Influence of Phytase and High Available Phosphorous Corn Diets on Solubility and Plant Uptake of P, Cu, and Zn in Poultry Manure and Manure-Amended Soils
… P and Cu were extracted with 0.01 M CaCl2 and Mehlich III extractant after incubation periods of 6 and 12 months. Corn was grown in a greenhouse experiment using these same Virginia soils and sand amended with 8.96 Mg/ha poultry manure from each of the five diet treatments. Poultry manure was …

Uptake of native and applied copper by corn and wheat as related to soil properties
… = 0.80, α = 0.001), but weakly correlated with Mehlich III-Cu (r = 0.28, α = 0.05). The DTPA-Cu showed high correlations with clay content (r = 0.98, α = 0.001) and SA (r = 0.93, α = 0. 001); whereas, Mehlich III-Cu did not correlate with these variables (α = 0.05). A second greenhouse …

Predicting Maize Yield, Nutrient Concentration and Uptake in P and K Fertilized Soils: Pressurized Hot Water and Other Alternatives to Mehlich I Extraction in Guatemala Soils
… countries with minimal validation. For example, Mehlich-I extraction of phosphorus (P) currently used extensively in Guatemala may not be suitable for its broad range of soils. At least four alternatives are available but are relatively untested [Bray 1, Mehlich III, Olsen and pressurized hot …

Adsorção e dessorção de arsênio em solos e substratos de mineração de ouro e práticas de mitigação de drenagem ácida em colunas de lixiviação
… de doses crescentes de As nos materiais, usando Mehlich III e resina de troca aniônica. A adaptação de metodologias foi satisfatória para o estudo de As em solos e substrato. O extrator Mehlich III mostrou-se adequado na determinação do As disponível, sendo inclusive sensível a capacidade tampão …

Phosphorus adsorption on sandy mine tailings: a comparison of treatments with fertilizers, wood ash, and compost
… based on standard Langmuir adsorption isotherms, Mehlich III extractable-P, and selected chemical and physical properties including pH, cation exchange capacity, compost rate, and specific surface area. Phosphorus adsorption decreased in the order UT, 1, 3, 6, 8, 9, and NS. Decrease in P …

Boron chemistry in selected Virginia soils and hydroxy aluminum and iron systems
… extractable B, mannitol exchangeable B and Mehlich III extractable B from the soils closely correlated with the concentrations in corn plants from native B in the greenhouse experiment. A yield response of corn plants to B application did not occur on the soils. Both tissue B concentration …
