Abstract: | Humic acid and fulvic acid are active compounds of humus, resulted fi'om decomposition process of organic matter. These compounds play an important part in increasing the plant growth. Therefore, their availability in the soil must be ensured. The level of humic acid and fulvic acid in the soil can be increased by adding organic fertilizers. Different kinds of organic fertilizers will produce a different content of humic acid and fulvic acid. It depends on the fertilizers contents of lignin, carbon, nitrogen, and its humification process in the soil. The purpose of this research is to find out the effect of organic fertilizers in humic acid and fulvic acid level on welsh onion and cauliflower field in PeI'mata Hati Farm, Cisarua Bogor. The treatments were arranged by Randomize Block Design with 8 treatments and 3 repetitions. Organic fertilizers used were chicken manure, goat manure, Tithonia diversifolia, Chiollloiaena odorata, banana stem compost, plants residue compost, chaffs charcoal, and Mucuna. Analysis of Variance and DMRT (Duncan's Multiple Range Test) were done at level (J. = 5%. The result indicated that level of humic acid and fulvic acid not significantly different caused organic fertilizers. The highest level of humic acid and fulvic acid (0.28% and 0.71%) was resulted from 25 kg of chicken manure treatment (as a control). |
