AMMONIUM SULFATE
4. ECOTOXICITY ID: 7783-20-2
DATE: 18.04.2006
Method:
other: see Test Condition
Year: 1984
GLP:
no data
Test substance: other TS: ammonium sulfate, no further details
Remark:
(1) - Other tests in the paper look at recovery of nematodes
when ammonium sulfate is removed, and at the effects of
ammonium sulfate on the tomato plants.
(2) - Neither ionic strength nor pH are controlled in this
experiment. Both will differ between the solutions used.
Result:
After 72 hours, 95% of the nematodes in the 9900 ppm N
solution had died. Approximately 50% of the nematodes in the
1100 ppm N solution had died after 72 hours.
Test condition: Nematodes were placed in 1100, 3300, or 9900 ppm N solutions
of ammonium sulfate in distilled water for 24, 48, and 72
hours.

Year: 1983
GLP:
no data
Test substance: other TS: ammonium sulfate, no furrther details
Result:
A LC50 value could not be determined because after 4 months
the number of nematodes had increased by a factor of 3. No
further details reported. However, the results indicate that
ammonium sulfate is not toxic to Nematoda in alpine pasture.
Test condition: Three sites of alpine pasture were treated with 100, 400,
and 1200 kg/ha ammonium sulfate on 13 June. Nematodes,
Testacea, and Ciliates were collected from each site and
from the control site on July 5, Sept 5, and Oct 18.
Nematode numbers dcreased on July 5, but by 18 October 3
times as many nematodes were collected from the fertilised
sites as from the control site.

A LC50 value could not be determined because the biomass
grew more at the highest dose level (1200 kg.ha) than in the
control. No further details reported. However, the results
indicate that ammonium sulfate (AS) at 1200 kg/ha is not
