- Abstract:
- ... The efforts of many municipalities to demolish abandoned residential dwellings (ARDs) are hampered by the presence of asbestos-containing materials (ACMs) in these structures. However, the extent of such materials is unknown. Our study sought to characterize ACMs present in ARDs demolished in Detroit.Working with the City of Detroit, we obtained information on all ARDs demolished from 2014 to 2017 ...

- Abstract:
- ... Commercial producers of containerized ornamental plants almost exclusively use soilless media as the substrate for growing the plants. Soilless media are composed primarily of organic materials as opposed to mineral soils. Significant amounts of pesticides can leach from pots containing soilless media to which pesticides have been added as drenches or top-dressings. One of the goals of this projec ...

- Abstract:
- ... Nanomaterial-specific response of quantum dots and the underlying mechanisms of their interaction with plants are poorly understood. In this study, we investigated the mechanism of cadmium sulfide-quantum dot (CdS-QD) uptake and stress response in soybean (Glycine max) plants using sensitive bio-analytical techniques. We adopted shotgun-proteomics and targeted analysis of metabolites and gene expr ...

- Abstract:
- ... Biodegradable polymers provide an opportunity to divert plastic waste from landfills, with composting as an alternative disposal route. However, some biodegradable polymers, such as poly (lactic acid) (PLA), do not biodegrade as fast as other organic wastes during composting, affecting their general acceptance in industrial composting facilities. Bioaugmentation, the addition of specific microbial ...

Development of less costly and less technically challenging remediation methods are needed; therefore, we developed a formulation based on micronized vermiculite that, when air-dried, resulted in a granular product containing the 4-chlorophenol (4-CP)-degrading Gram-positive bacterium Arthroba ...

Melilotus siculus is a waterlogging-tolerant annual forage legume, but data were lacking for the effects of root-zone hypoxia on nodulated plants reliant on N₂ fixation. The aim was to compare the waterlogging tolerance and physiology of M. siculus reliant on N₂ fixation or with access to NO₃⁻. A factorial experiment imposed treatments of water leve ...

Experiments were conducted to modify an existing method for the production of inoculum in temperate climates to make it more readily adoptable by farmers. Perlite, vermiculite, and peat based potting media were tested as diluents of yard clipp ...

- Abstract:
- ... Arbuscular mycorrhizal [AM] fungi are potentially important tools in sustainable agriculture due to their roles in crop nutrient uptake, disease resistance, and water relations and in stabilizing soil aggregates. Inocula of these fungi can be effectively produced on-farm in mixtures of compost and vermiculite with a suitable plant host, such as bahiagrass (Paspalum notatum Flugge). Success of this ...

- Abstract:
- ... BACKGROUND AND AIMS: Basic information about the root and root nodule structure of leguminous crop plants is incomplete, with many aspects remaining unresolved. Peanut (Arachis hypogaea) forms root nodules in a unique process. Structures of various peanut root types were studied with emphasis on insufficiently characterized lateral roots, changes in roots during their ontogenesis and root modifica ...

- Abstract:
- ... Rising transportation cost of peat moss from Canada or Europe is negatively affecting the profitability of many greenhouse operators. The industry has recognized a need to explore alternatives to peat for greenhouse substrates. The objective of this research was to evaluate processed whole pine (Pinus taeda) trees (WT) as an alternative growth substrate for greenhouse crops. Studies were conducted ...

- Abstract:
- ... The relationship between soil test P (STP) and dissolved reactive P (DRP) in runoff has been shown to vary with soil type due to differences in soil properties. This study was conducted to determine the effect of mineralogy on P sorption behavior and DRP losses in runoff using simulated rainfall. Nine different soil types were sampled from four different fields to provide a range in STP. Unamended ...

- Abstract:
- ... In the present study, root hydrotropism in an agravitropic mutant of Pisum sativum L. grown in vermiculite with a steep water potential gradient was examined. When wet and dry vermiculite were placed side by side, water diffused from the wet (-0.04 MPa) to the dry (-1.2 MPa) and a steep water potential gradient became apparent in the dry vermiculite close to the boundary between the two. The exten ...

- Abstract:
- ... Colletotrichum truncatum (Schwein.) Andrus and Moore NRRL 13737 (= NRRL 18434) is a fungal plant pathogen which shows promise as a bioherbicide against the troublesome weed Sesbania exaltata (Raf.) Rydb. ex A. W. Hill. Previous studies showed similar amounts of spores were produced/ml of medium in liquid and solid-state fermentations. In this study, Colletotrichum truncatum spores were produced in ...

- Abstract:
- ... In 1980, corn was harvested from six 15-ft rows in each of 67 fields in Georgia for aflatoxin analysis. Every sixth ear from each field was placed in a sample bag to be dried the day of collection. The rest of the corn was husked and shipped to Peoria in cardboard boxes. When undried ear samples arrived in Peoria, each sample was randomly separated into 5 equivalent subsamples. One set of 67 subsa ...
