PENGARUH INSEKTISIDA BAYRUSIL 25 EC TERHADAP LAJU DEKOMPOSISI SERASAH
An observation has been done by using three kinds of factors, consisting of 24 combinations. They are three litters of cabbages, corn leaves and straw ; the size of mesh bag apertures ( S = 700 micron, M = 1 000 micron, L = 1400 micron and LL = 2500 micron 7 and the insect iside of Bayrusi1 25 EC un...

| Summary: | An observation has been done by using three kinds of factors, consisting of 24 combinations. They are three litters of cabbages, corn leaves and straw ; the size of mesh bag apertures ( S = 700 micron, M = 1 000 micron, L = 1400 micron and LL = 2500 micron 7 and the insect iside of Bayrusi1 25 EC unsprayed and sprayed with a dosage of 2 cc/it. The result showed that the application of insectiside influenced the rate o f dec,e e n e t_1.eri. There was a significance change of litter weight during the experiment ; the litter of the cabbage was the fastest to decompose, then the corn leaves and the least was that of the straw. The thr ee combination of factors showed that the size of the 1400 micron of mesh bag apertures either to be sprayed or unsprayed was significant. The result also showed there was a significant decrease of soil fauna population, due to the application of insecticide. The analysis showed that the chemical content and C/N ratio_ chan ged during the experiment. |
