Abstract

The study of nutrient components in co-composted sludge, from Serm Suk Co., Ltd. applied on Brassica chinensis growth had the objective to reduce the amount of waste from beverage processing which the factory did not eradicate properly. This experimental research helped reducing the problem of sludge eradication by using the sludge as a fertilizer. The experiment was divided into 2 sets. 1) The dried leaves and garbage 2) The dried leaves, garbage and sludge. All sets have 60 . Collect data every 5 days. The growth rate of each part was measured, including the height of trunk and number of leaves. Found that in the set 2 was the best nutrients, the values are as follows, organic matter is 30.64% (w/w), carbon is 17:11% (w/w), the ratio of carbon : nitrogen is 22:1, total nitrogen is 0.80%, total phosphorus is 0.43% and pH is 6.35. It also affected to the growth of the Brassica chinensis better than set 1 and set 3. The growth of the highest level at average at 7.7 cm and the average number of leaves at 4. This set was the best ratio for growing Brassica chinensis and reducing the waste from factory as well.
