Starter Fertilizers for No-Till and Minimum-Till Corn
… study, the risk of injury from seed-placed fertilizers increased when soil temperatures increased from 61 to 67$\sp\circ$F. Wetting the root zone to field capacity within 48 hours after planting enhanced the effectiveness of seed-placed fertilizers by increasing early plant growth and …

Comparisons of crop yields using semi-organic and inorganic fertilizers
A series of experiments is described in which a semi-organic fertilizer is compared to the more widely used inorganic type. A semi-organic fertilizer contains a base of organic materials to which is added a mixture of inorganic salts to make up a suitable analysis. The results from three years …

Development of Novel Slow-Release Micronutrient Fertilizers Using Mechanochemical Synthesis
… the formulation of boron (B) and molybdenum (Mo) fertilizers. More generically, the aim was to combine sustainable engineering and fertilizer manufacturing. The thesis consists of 6 chapters, including an overview of the literature relevant to this project (Chapter 1). Subsequent chapters describe …

Mineral content of vegetables grown with organic and mineral fertilizers
… of vegetables grown with organic and mineral fertilizers was investigated in order to determine the nutritional superiority or non-superiority of organically raised foods. Duplicate samples of split peas, pinto beans, kidney beans, blackeye peas and tomatoes of each treatment were wet washed …

INITIAL IMPACTS OF DIFFERENT FERTILIZERS ON IMPROVED EAST TEXAS EQUINE PASTURES
<p>ABSTRACT</p> <p>In Texas, approximately 1.6 million acres support an equine population exceeding 748,000 horses. This study assessed the effects of organic and inorganic fertilizer treatments on improved Bermudagrass (BG) and other vegetation (OTH) in overgrazed equine pastures at the Stephen F. …

Novel Coated Fertilizers as Multi-Nutrient Sources for Soybeans and Tomatoes
Virginia's Coastal Plain region contains the majority of the state's agricultural production despite having low nutrient soils. The soils in this region are predominantly coarse-textured acid soils with low cation exchange capacities (CEC) (< 3 cmol kg-1) and thus frequently exhibit nutrient …

Response of cool-season turfgrass to foliar applied and stabilized nitrogen fertilizers
… objective was to assess whether stabilized N fertilizers offered a benefit over unamended sources under field conditions. Experiments to address these objectives were carried out at the Landscape Horticulture Research Center in Urbana, IL. The results indicate that approximately 7-34% of …

Environmental considerations for interactions between agricultural herbicides and nitrogen fertilizers in water
Agricultural herbicides and fertilizers are widely used and necessary for the production of food and feed. Each herbicide and fertilizer must be extensively researched prior to being released for commercial use. However, some research indicates that an interaction may occur when fertilizers and …

Evaluating Nitrogen Containing Controlled Release Fertilizers At Stand Establishment In Loblolly Pine
… of conventional and controlled release N fertilizers was evaluated in a greenhouse study and at two field trials in the Virginia Piedmont, in 2002 and 2003. The greenhouse study evaluated five fertilizer treatments; 1) check with no fertilizer; 2) granular ammonium nitrate (10-10-10 + …

Hydrolysis of formamide and volatilization of ammonia from nitrogen fertilizers added to soils
… on NH(,3) volatilization from various N fertilizers applied to soils (134 mg N/chamber) under laboratory conditions showed that high amounts of NH(,3) were lost in 12 days from urea (33 to 40%) and formamide (31 to 36%) when surface applied to acid and calcareous soils. Ammonia …
