UTILIZATION OF VINASSE AS A SOURCE OF POTASSIUM FOR SOME CROPS GROWN IN UPPER EGYPT
Ahmed Mohamed Abd-El-Kawa;
Abstract
Sugar industry from cane is one of the oldest industries in Egypt. More than
12 million m3 of sugar cane are milled annually through eight sugar factories along four Governorates in Upper Egypt. Beside the sugar, which is, the main product of this industry there arc some other by-products are produced in a huge
quantities. Large amounts of sugar industry by-products are accumulated yearly in the nearby of sugar cane factories. These by-products include, filter mud cake, vinasse, and bagasse ash. These wastes accumulate and represent a huge source ofhazardeous pollution problem for the environment.
The sugar and integrated industry company in Hawmdyia produces more than 50000 tons of filter mud cake, 12500 m3 of vinasse plus 10000 m3 of bagasse ash, which may accumulate yearly and will exert many hazardous effects on the
environment (Hassanein, 1999). The chemical analysis of vinasse showed that it brownish black liquid and characterized by acidic pH, high electrical conductivity, salt content, organic matter, potassium, phosphorus, sodium, iron, manganese, zinc and cupper. Therefore this large amount of vinasse can hann the environment, causing salinization and river Nile pollution. To overcome these problems here is an attempt to utilization this by-product as a source of p9tassium and micronutrient for soil fertilization.
Wheat and com are the most important cereal crops in Egypt since both are being used in feeding human and animals so they are cultivated intensively through country. Since the supplies of new additions of mud were ceasedue to the construction the high dam, the soil available potassium fonn was reduced by intensive agriculture. Therefore, large quantities of mineral fertilizers should be added to the soil to compensate the shortage of potassium as an important element for plant growth.
Vinasse is a good source of potassium. Nowadays, the tendency in the world is substitute the mineral fertilizers with the organic and bio-fertilizers.
