Autor: M. H. Stolt, J. R. Fulcher, J. R. Mckenna, D. C. Martens, T. W. Simpson, J. C. Baker

Publikováno v: Soil Science. 166:29-37

Minable quantities of heavy minerals occur in prime agricultural lands of the Atlantic Coastal Plain. We evaluated the use of yard waste compost to reclaim tailings mined from these lands. A 30 × 60-m area was excavated to a depth of 5 m to establis

Publikováno v: Communications in Soil Science and Plant Analysis. 30:457-470

An improved management of phosphorus (P) is crucial for increasing crop production and improving environmental quality of acid infertile soils. Laboratory analyses and greenhouse experiments were conducted to evaluate effects of phosphate rock (PR),

Coal combustion by products (BP) and phosphate rock (PR) have been widely used as cost-effective amendments for acid soils. Information is needed on the proper combination of BP with chemical fertilizers or other organic and inorganic amendments to i

Publikováno v: Soil Science Society of America Journal. 62:1538-1541

In the ascorbic acid-molybdenum blue method for measurement of soluble P, the relationship between color intensity and P concentration in solution and color stability is greatly affected by organic and inorganic ligands such as oxalate, citrate, tart

Comparison of Mehlich 3‐ and bray 1‐extractable phosphorus levels in a Starr clay loam amended with poultry litter

Autor: D. C. Martens, D. E. Starner, J. R. McKenna, D. W. Lucero

Publikováno v: Communications in Soil Science and Plant Analysis. 29:1133-1142

Two soil tests commonly used to characterize the availability of soil phosphorus (P) are Bray P1 (B1) and Mehlich 3 (M3) extradants. The objective of this investigation was to compare M3‐ and B1‐extractable P levels in a Starr clay loam (fine‐l

Fluidized bed combustion by‐product treatment and leaching of acid soil affects growth and boron acquisition of maize

Autor: K. D. Ritchey, M. Zaifnejad, Virupax C. Baligar, D. C. Martens, R. B. Clark

Publikováno v: Communications in Soil Science and Plant Analysis. 29:255-267

Fluidized bed combustion bottom ash (FBCBA) from coal burning power plants often contain substances that detrimentally affect plant growth [(e.g., boron (B)] when applied to soil. Leaf symptoms similar to B toxicity appeared when maize (Zea mays L.)

Ionic Strength Effects on Sulfate and Phosphate Adsorption on γ-Alumina and Kaolinite: Triple-Layer Model

Autor: Virupax C. Baligar, D. C. Martens, L. W. Zelazny, L. M. He, K. D. Ritchey

Publikováno v: Soil Science Society of America Journal. 61:784-793

It is known that PO 4 is retained by soils through ligand exchange, i.e., inner sphere complexation, but the mechanism for SO 4 adsorption at the mineral-water interface has been in debate. By studying the effects of ionic strength on ion adsorption,

Publikováno v: Biology and Fertility of Soils. 24:329-334

Phosphate rock (PR), limestone, coal combustion by-product (CCBP) high in Ca and high organic manures are potential amendments for increasing agricultural production in the acidic soils of the Appalachian region. The objective of this study was to ex
