Abstract: The research focuses on the influence of the assorted usage of wormcast and pig manure compost on the composition change of humus and amaranth's yield through pot experiment. Results showed that humus, humic acid, fulvic acid showed a trend of increase as a whole, and the increasing degree enlarged when treated with in- creased proportion of wormcast; humin, humin /humus showed a trend of decrease as a whole, and the decreasing de- gree reduced when treated with increased proportion of wormcast; humic acid /fulvic acid increased first and then decreased, while it showed a trend of increase as a whole, and the increasing degree reduced when treated with in- creased proportion of wormcast. At the beginning period of cultivation amaranth' s yield reached the highest when treated with 40% wormcast, and the lowest when treated with pure wormcast; at the later period of cultivation ama- ranth's yield reached the lowest when treated with 60% wormcast, and the highest when treated with pure pig ma- nure compost. Results showed that under the condition of insufficient nutrients, there was no relevance between hu- mus content and yield of amaranth.
