Gyeongnam Provincial Agricultural Research Institute Conducts Agricultural Water Quality Survey ... On the Occasion of 'World Water Day'

A Gyeongnam Agricultural Research and Extension Services official is conducting a water quality test for agricultural water.

[Asia Economy Yeongnam Reporting Headquarters Reporter Park Saeyan] Gyeongsangnam-do Agricultural Research and Extension Services announced on the 19th that, in celebration of World Water Day, it will begin a full-scale water quality survey of agricultural water starting in April in collaboration with the Rural Development Administration.

The Gyeongnam Agricultural Research and Extension Services regularly analyzes the water quality of agricultural river water and groundwater to manage the quality of agricultural water necessary for producing eco-friendly agricultural products.

Last year, pH, dissolved oxygen, nitrogen, and 14 general components as well as 8 heavy metals including cadmium, lead, and chromium were analyzed three times in April, July, and October at 39 river water sites and 20 groundwater sites within the province.

Test results showed that the BOD (biochemical oxygen demand) content of river water averaged 1.6 mg per liter (standard 8 mg), nitrate nitrogen content in groundwater was 8.89 mg (standard 20.0 mg), chlorine content was 22.1 mg (standard 250 mg), and dissolved phosphorus content was below 0.1 mg in both river water and groundwater.

The heavy metals cadmium, lead, mercury, and arsenic were detected below the detection limit, confirming that there is no problem using the water for agricultural purposes.

A Gyeongnam Agricultural Research and Extension Services official emphasized, "97.2% of the water on Earth is seawater, and only 2.8% of freshwater on land is available for human use," adding, "Sustainable management of agricultural water necessary for food production cannot be emphasized enough."
