◉ Introduction to Soil Testing of Agricultural Land
Agricultural land refers to cultivated land, garden land and grassland. Soil pollution of agricultural land will adversely affect the quality and safety of agricultural products, the growth of crops, and the ecological environment of the soil.
Agricultural land soil pollution detection is the sampling and testing of agricultural land soil to determine the type and concentration of pollutants in the soil.
◉ Scope of Test
(1) Cultivated land soil: including paddy field, irrigated land and dry land soil;
(2) Garden soil: including orchard and tea garden soil;
(3) Grassland soil: including natural grassland and artificial grassland soil.
◉ Test Items
(1) Trace elements: effective zinc, effective silicon, effective sulfur, exchangeable calcium, effective iron, effective manganese, effective copper, exchangeable magnesium, exchangeable potassium, exchangeable sodium, etc.
(2) Conventional indicators: sulfate, nitrate nitrogen, ammonium nitrogen, pH, total salt content, chloride ion, nitrite nitrogen, etc.
(3) Heavy metal pollution: mercury, nickel, copper, lead, arsenic, cadmium, chromium, zinc, etc.
(4) Organic pollutants: mineral oil, volatile organic compounds, benzopyrene, organochlorine pesticides, organophosphorus pesticides, etc.
(5) Fertility indicators: total nitrogen, total phosphorus, total potassium, organic matter, organic carbon, hydrolyzable nitrogen, available phosphorus, available potassium, etc.
