Agroecological monitoring of irrigating and waste waters of rice irrigating system

In conditions of field experience data under the content of nitrogen, phosphorus compounds in irrigating and waste water of rice irrigating system are obtained. It is established, that the content of nitric compounds in irrigating and waste water is essential below maximum concentration limit and does not represent ecological hazard. Entering of phosphoric fertilizers practically does not influence receipt of phosphates in water receivers. The content of water-soluble salts in water of waste canals was more, than in water of irrigation canals. Water of waste canal at dairy-commodity farm was characterized by excess of maximum concentration limit under the content of the water-soluble salts, the increased content of nitric connections and presence of mobile phosphorus.
