Degradation of Soil Fumigants as Affected by Initial Concentration and Temperature

Degradation of soil fumigants as affected by initial concentration and temperature.

Soil fumigation using shank injection creates high fumigant concentration gradients in soil from the injection point to the soil surface. A temperature gradient also exists along the soil profile. We studied the degradation of methyl isothiocyanate (MITC) and 1,3-dichloropropene (1,3-D) in an Arlington sandy loam (coarse-loamy, mixed, thermic Haplic Durixeralf) at four temperatures and four ini...

Sulfadimethoxine degradation kinetics in manure as affected by initial concentration, moisture, and temperature.

Sulfadimethoxine is a widely used sulfonamide veterinary antibiotic and could be a source of agricultural contamination. Therefore, information is needed about its degradation kinetics in manure under aerobic conditions. Based on the analysis of first-order kinetics and the assumption that sulfadimethoxine availability for degradation in manure could be limiting, a new kinetic model was develop...

Infiltration in cracking clay soils as affected by initial soil moisture content

Monte Carlo Simulation of the Shelf Life of Pasteurized Milk as Affected by Temperature and Initial Concentration of Spoilage Organisms

ARTICLES SUMMARY Predictive microbiology and quantitative microbial risk assessment are rapidly developing disciplines that use mathematical models to quantitatively estimate the presence and growth of microbes in food products. This report explains how these techniques were used in troubleshooting a milk spoilage problem. The central objective of this article is to demonstrate the concept and ...
