Abstract: Application of swine (Sus scrofa domesticus) manure can
lead to elevated runoff concentrations of organic matter and
nutrients. This  experiment was conducted to assess the
influences of swine manure treatment (0 and 220 kg/ha nitrogen
applied) and drying interval (4, 7, and  14 days) between manure
application and first runoff event on quality of runoff from
fescue (Festuca arundinacea Schreb.) plots. Runoff was  generated
from simulated rainfall (50 mm/h) and sampled at 0.08 h intervals
during runoff. Flow-weighted composite runoff samples from each 
treatment and replication were analyzed for nitrate nitrogen
(NO3(-)N), ammonia nitrogen (NH3(-)N), total Kjeldahl nitrogen
(TKN), total  phosphorus (TP), chemical oxygen demand (COD), and
total suspended solids (TSS). One set per treatment of the
noncomposited runoff  samples was also analyzed. Runoff
concentrations of all manure constituents investigated were
higher for the manure-treated plots than for the  untreated
plots. Runoff NO3(-)N increased with drying interval due to
nitrification, but concentrations of other manure constituents
were  unaffected by drying interval. Amounts of constituents lost
from the plots in runoff were higher for the manure-treated plots
than for the  untreated plots, but all (including NO3(-)N) losses
were found independent of drying interval. Analyses of the
noncomposited runoff samples  revealed high variability in the
response of runoff quality to time after the beginning of runoff
for all parameters investigated. Data from the  non-composited
samples did not lend itself to generalized descriptions of
changes with respect to time of runoff concentrations of manure 
constituents.

Abstract: Addition of piggery manure to soils over 5 yr (manured
soils) increased the amount of Cu extracted by EDTA and 
diethylenetriaminepentaacetic acid (DTPA) compared to selected
reference soils. DTPA-extractable Cu ranged from about 3 to 10 p
g Cu g-1  soil in the manured soils and from about 1 to 2
micrograms Cu g soil in the reference soils. Although the soil Cu
concentrations in the manured  soils were many times smaller than
currently permitted, the increase in DTPA- or EDTA-extractable Cu
was correlated with a 10- to a 1000- fold increase in the number
of aerobic Cu-resistant bacteria. Although the Cu was mainly
concentrated in the plough layer (15 cm) of the  manured soils,
Cu-resistant bacteria were also detected down to 110 cm soil
depth. In contrast, no such differences were found between the
total  number of colony forming units, total microbial biomass or
the degree of Cu-resistance of fungi and anaerobic bacteria
between manured and  reference soils. It is suggested that the
degree of Cu-resistance of the aerobic soil bacteria may provide
a sensitive measure of Cu bioavailability  in soil. In general,
bacteria were more sensitive to Cu than fungi. All of the 42
Cu-resistant bacterial strains investigated were oxidase-positive 
and 50% of the strains were pigmented. In contrast, only 20% of
the 37 Cu-sensitive bacterial strains investigated were
oxidase-positive and  none were pigmented. Cu-resistant bacteria
exhibited more resistance to several antibiotics and heavy metals
than Cu-sensitive bacteria.

Abstract: Antipathogenic activity of a compost prepared of the
solid phase of anaerobically fermented pig slurry has been tested
in laboratory and  glasshouse experiments. It was shown that this
compost sensibly limited the severity of pathogenic effect of
Fusarium oxysporum f. sp. lini and  diminished incidence of
Phomopsis sclerotioides with cucumber cultivated in naturally
infected soil. Laboratory experiments have shown that  there is
at least one bacterial biological element responsible for
induction and acceleration of autolysis of pathogenic fungi.
