Assessing toxicity of fertilizer nitrogen phosphorus sulfur brand NP + S = 16: 20 + 12 on earthworms found that only at a concentration of 1000 mg / kg dry soil animals mortality was 16.7%. The medial concentration LC50 for the drug is 2994 mg / kg dry soil. Due to the fact that the application rate of fertilizer nitrogen phosphorus sulfur brand NP + S = 16: 20 + 12 in the field is - for the main application crops normally 200 - 300 kg / ha should be considered that the concentration nitrogen-phosphorus fertilizer sulfur brand NP + S = 16: 20 + 12 are used for treatments lower than those that are toxic to earthworms.
