[Nitrate content in the soils and vegetable crops in the villages of one district].
The authors determine the content of nitrates in soil samples and the vegetables grown on them (lettuce, spinach, onion, garlic) via sensitive spectrophotometric methods with phenodisulphonic acid and reduction with cadmium column. The lowest nitrates content was established in the soil samples and vegetables grown by AIC, followed by the private arms, and the highest - in the green-horse vegetables and soil samples, owing mainly to the technology of production.
