Acute toxicity to Eisenia fetida was tested
in a study according to EPA/600/3-88/029 (1988) using Ammonium chloride
as test substance (CAS: 12125 -02 -9). The 14d- LC50 value was 201 mg/kg
soil (Yeardley et al. 1995, value related to Ammonium sulphate). Ma et
al. (1990) studied long-term effects (20 yr) on nitrogenous fertilizers
usage on lumbricid earthworms in soil. This study revealed that,
Ammonium sulphate (5 applications per year of 60 -180 kg N/ha had
effects on earthworm numbers and biomass. However, the effects were
attributed to the lowering of pH observed in parallel with Ammonium
sulphate application in the absence of liming.
