The pace of change in our personal and business lives
continues to accelerate at an ever increasing rate.
Accordingly, it is necessary to periodically update
information in a long-running reference such as Handbook
for Vegetable Growers. Our goal in this revision is to provide
up-to-date information on vegetable crops for growers,
students, extension personnel, crop consultants, and all
those concerned with commercial production and marketing
Point source wastewater treatment-Farms with large livestock and poultry operations, such as
factory farms, are called concentrated animal feeding operations or confined animal feeding
operations in the U.S. and are being subject to increasing government regulation. Animal slurries are
usually treated by containment in lagoons before disposal by spray or trickle application to grassland.
Constructed wetlands are sometimes used to facilitate treatment of animal wastes, as are anaerobic

the importance of immediate, exclusive breastfeeding and
skin-to-skin contact to keep their babies warm.
An additional benefit of hydrogen peroxide and Fenton's Reagent is the
temporary increase of oxygen levels in and around the treatment area. The
increased oxygen levels at the fringes of the treatment area can enhance naturally
occurring aerobic biodegradation processes that reduce contaminant mass. While
there may be concerns about oxidizing hydrocarbon-degrading bacteria in the
chemical oxidation treatment area, many studies have shown that soil cannot be
readily sterilized by Fenton's Reagent and that microbial populations rapidly
rebound following chemical oxidation treatment.
