Detoxification of atrazine in soils results from both chemical
hydrolysis and microbial degradation.
Infrared analysis was used
to study the hydrolysis of atrazine upon interaction with soil
colloids
and to ascertain the existence of enol, keto, and protonated-keto
forms of hydroxyatrazine.
Evolution of ¹⁴CO₂ from ¹⁴C-atrazine
and ¹⁴C-hydroxyatrazine was indicative...
The physical and chemical properties of soils greatly affect the
toxicity of bromacil and picloram. Consequently, a knowledge of the
parameters which influence the soil inactivation of these herbicides
is necessary to determine proper application rates for good weed control.
Enhancement in phytotoxicity with the addition of surfactants or
surface...
Solid municipal waste was applied to Sagehill sand at rates of
0, 100, 200, and 400 tons/acre (0, 67, 133, and 267 tons dry matter).
Sewage sludge (2% solids) was applied at 55 gallons per ton of solid
waste. Hyslop winter wheat was planted as a cover crop in October...
Intensification of livestock operations has enhanced the problem
of animal waste disposal. Since high application rates of the
waste to soils would help elevate the problem, a study was established
to determine water quality as affected by applications of dairy
waste slurries to tiled and untiled soils.
Dairy cow waste...
Waste products from industry have often been disposed in
landfills without regard for any beneficial uses of the product in
agricultural production. This research was conducted to determine
the effect of a refractory metal processing waste product on (a) soil
chemical and physical properties, (b) perennial ryegrass forage
quality and...
Metropolitan areas today must dispose large volumes of
sewage sludge produced during the wastewater treatment process.
This research was conducted to study the effect of large applications
of municipal sewage sludge on (a) the distribution of N and trace
elements (Cd, Cr, Cu, Mn, Ni, Zn) in the soil profile,...
