A field study was conducted over a 30 mo period to examine movement of Cd, Tl, and V through the profile of a Coastal Plain soil (Typic Kandiudult) and the availability of these trace metals to bush bean (Phaseolus vulgaris L.) plants. The metals wer

Dicyandiamide effects on nitrification and total inorganic soil nitrogen in sandy soils

Autor: H. W. Martin, Donald A. Graetz, D. R. Hensel, S. J. Locascio

Publikováno v: Communications in Soil Science and Plant Analysis. 28:613-633

Inhibition of nitrification in soil results in a decreased ratio of nitrate‐nitrogen (NO3‐N) to ammonium‐nitrogen (NH4‐N). If the conditions for NO3‐N loss by leaching or denitrification exist, nitrification inhibitors should increase conce

Chicory (Cichorium intybus L.) and dandelion (Taraxacum officinale Web.) as phytoindicators of cadmium contamination

Autor: L. Simon, Domy C. Adriano, H. W. Martin

Publikováno v: Water, Air, & Soil Pollution. 91:351-362

Chicory (Cichorium intybus L.) and dandelion (Taraxacum officinale Web.) were demonstrated to be potential indicator plants for heavy metal contaminated sites. Chicory, grown with 0.5–50 μM cadmium (Cd) in nutrient solution, accumulated 10–300 �

Evaluation of three herbaceous index plant species for bioavailability of soil cadmium, chromium, nickel and vanadium

Autor: H. W. Martin, Domy C. Adriano, L. Simon, T. R. Young, Daniel I. Kaplan

Publikováno v: Plant and Soil. 182:199-207

Uncultivated plants growing on disturbed sites may be useful for assessing the bioavailability of some metals in soils, and thus the potential for metal mobilization up the terrestrial food chain, an important element in ecological risk assessment. A

Tomato response to long‐term potassium and lime application on a sandy ultisol high in non‐exchangeable potassium

Autor: W. C. Liebhardt, H. W. Martin

Publikováno v: Journal of Plant Nutrition. 17:1751-1768

In a ten‐year study of potassium (K) and lime application to a Kalmia sandy loam (fine‐loamy, siliceous, thermic Typic Hapludult), a soil high in nonexchangeable K, corn (Zea mays L.) and soybean [Glycine max (L.) Herr.] have not responded to app

Biogeochemical ecology ofThiothrixspp. In underwater limestone caves

Autor: R. L. Brigmon, H. W. Martin, T. L. Morris, Stephen G. Zam, Gabriel Bitton

Publikováno v: Geomicrobiology Journal. 12:141-159

Thiothrix spp., sulfide‐oxidizing mixotrophic bacteria, were sampled from visible colonies in the Floridan aquifer in several underwater caves, sinkholes, and springs below the water table in North Florida. Bacteria samples were collected by cave d

Contrasts of nitrapyrin, dicyandiamide, and iso‐butylidene diurea effects on total inorganic soil nitrogen

Autor: H. W. Martin, D. R. Hensel, Donald A. Graetz, S. J. Locascio

Publikováno v: Communications in Soil Science and Plant Analysis. 25:547-565

While much research has been done with nitrification inhibitors, little information exists on their effects on total inorganic soil nitrogen (N) (TISN) (NH4 +‐N + NO3 ‐‐N). The objective of this study was to compare the effects of 2‐chloro‐

Nitrification Inhibitor Influences on Potato

Autor: D. R. Hensel, Donald A. Graetz, S. J. Locascio, H. W. Martin

Publikováno v: Agronomy Journal. 85:651-655

Nitrification inhibitors may reduce loss of fertilizer N from the root zone by reducing leaching and denitrification. This reduced N loss should be reflected in increased crop yields. These studies were conducted to determine if potato yield, specifi
