Current Research
T. Ohno - My current
research efforts focus on the use of crop rotations and animal
manures to improve soil productivity and increase soil phosphorus
availability. My specific projects involve: 1) the spectroscopic and
macroscopic characterization of humic and fulvic acids, as well as
water-soluble organic matter, isolated from cropping system studies
which have been in place for eight to twelve years and 2)
interaction of these isolated organic matter ligands on the kinetics
of phosphorus desorption from soils. These studies will allow
evaluation of how cropping systems may be designed to increase
phosphorus use efficiency which would befit growers by lowering
required chemical inputs and society with lower potential for
adverse environmental impacts from excessive phosphorus use.
M. Susan Erich -My
research relates to the effects of soil amendments on soil chemical
and physical properties. Specifically I have investigated the
effects of naturally derived organic ligands on the solubility of
phosphorus in soils, as well as environmentally and agronomically
appropriate soil testing for phosphorus. I have also studied the
production of phenolics with allelopathic potential in soils amended
with plant residues and compost.
During the decomposition of organic material in soils substantial
amounts of water-soluble carbon, which can potentially affect soil
chemical and biological processes via interaction with organisms and
soil surfaces, may be produced. These soluble carbon compounds may
suppress or enhance plant growth, depending on the identities and
concentrations of the compounds involved, the identities of the
target plants, soil and climatic conditions, and other factors.
Results of a number of studies, including those at the University of
Maine, indicate that residues of legume species used as green
manures can be weed-suppressive, and suggest that the effect may be
mediated through the production of soluble organic compounds. My
research program is designed to build upon and extend the promising
results of previous studies.
