A Comparative Study of Composted Organic Wastes and IBDU Fertilizer in Nitrogen Utilization by Bentgrass Cultivars
… absorption efficiency in relation to an organic slow release fertilizer. Western's compost facility supplied the two different organic wastes, which had been composted for 1 year. The materials used were composted urban leaf litter, sawdust/manure mixture at a 50/50 ratio by volume and an organic …

The Black Soldier Fly, Hermetia illucens Linnaeus (Diptera: Stratiomyidae): A Novel Approach to Combat Food Waste in Windsor-Essex.
… waste reduction within the area. As I measured slower development to adult and reduced waste reduction efficiency compared to a control diet of poultry feed, I investigated the potential role of pre-digestion and fermentation with beneficial microbes in the black soldier fly waste reduction …

Quantifying the effects of fertilizer type, source, and concentration on the post-production growth of containerized culinary herbs
… our first experiment we determined the effect of fertilizer type, source, and concentration on the post-harvest regrowth of containerized culinary herbs. Four different herb species sweet basil (Ocimum basilicum ‘Nufar’), cilantro (Coriandrum sativum ‘Santo’), dill (Anethum graveolens ‘Hera’) and …

Development of a seeding pellet system for use in soil conservation forestry
… organic food industry waste streams or synthetic fertilizers, with biochar selected as a substrate, with pill capsules as containers or microbial biofilms and organic materials as binding agents. The trial was screened for both germination and plant height to discern whether the various pellet …

First-year growth and survival of habitat revegetation trials on the lower Colorado River, Mexico
… far less than spring-planted screwbean mesquite. Slow-release fertilizer had no effect on mesquite seedlings planted in the fall. Seedlings planted in the spring from 2.8-L pots and 12-cm plugs had similar first-year growth for both mesquite species. Rooted cuttings of cottonwoods grew taller on …

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 …

Impacts of Spring-interseeded Cover Crops on Late-emerging Weed Suppression and Ground Cover in Corn (Zea mays L.) Production Systems
… crop may be used as a fall forage, act as a slow release fertilizer source the following year, and provide ground cover to reduce soil erosion. In South Dakota, cover crop establishment cannot occur after corn harvest, as the growing season is too short, cold, and often dry. Therefore, …

Investigating pretreatment methods for struvite precipitation in liquid dairy manure
… promising technology because it can be used as a slow-release fertilizer. The objective of this study was to investigate different pretreatment methods to enhance struvite precipitation in dairy manure. Generally there are two challenges that need to be overcome to precipitate struvite in liquid …

Synthesis of zeolites and their application as soil amendments to increase crop yield and potentially act as controlled release fertilizers.
… growth, their cation exchange capacity (CEC) and slow-release fertilizer properties. Most work on slow-release fertilizers has focused on natural Clinoptilolite, Phillipsite and Chabazite. The aim of this study was to synthesize zeolites, study their effectiveness as soil amendments and their …

Five-year fertilizer and ground cover effects on surface-mine soils and pine growth
… and growth of tree stands at time of bond-release eligibility and beyond is an important beginning for returning mined lands to a productive state. In order to ensure reforestation success, biological constraints, including low mine soil fertility and competition from herbaceous ground …
