NUTRITIOUS SUBSTRATUM FROM WASTE WATER CONTAINING MANURE

 Studyingthe possibility of using livestock waste waters for cultivation of green fodderby hydroponics has practical value. Sewage of hydroflushing system of manureremoval (manure dilution approximately by 10 times) after mechanical cleaninghas the alkalescent reaction caused by availability of ammonium bicarbonate inthem. рН is favorable for growth of plants and for use of ammonium nitrogen.The dry remaining balance constitutes more than 5 g/l. The harvest of green fodderin control option is higher, than in experimental, and constitutes 21.29 m and20.50 kg/m2 respectively, and content of carotene in both casesconstitutes more than 60 mg/kg of a fodder. In the course of cultivation ofgreen fodder on nutritious substratum, concentration of ammonium nitrogen in itgradually decreased, and by the end of cultivation decrease constituted 30–80%.Though in percentage terms decrease in case of lower concentration is higherthan it, than in case of high, the absolute value of consumption of nitrogen ofsubjects is more, than concentration is higher than it in a nutritioussubstratum. When given to plants of sewage with an initial ash-content of 2.5g/l, it decreases to 1.7 g/l, i. e. by 30 %. Decrease in an ash-content fromconcentration of 4.5 g/l constitutes only 6 %, and in case of an initialash-content of 6.0 g/l any noticeable change is noted, i. e. it remainspractically at the same level. The technology of preparation of a nutritioussubstratum from the waste water containing manure is developed. The green foddergrown on a nutritious substratum is used in livestock production.
