Industrial puffed rice scrap increases the carbon/nitrogen ratio in carbon-poor biodegradable organic matter, such as broiler chicken beddings (C/N= 14.6) (droppings + sunflower husks), optimizing the composting process. In Eisenia fetida field experiences (bimonthly sampling) done on cultures managed through self-inoculation (addition of 8-16% scrap to the chicken bedding), the substrate was accepted. Population increase and cocoon production, measured 127 days after the start, were not significantly different from control plots (broiler chicken bedding). Population size expanded with a nominal (nd) and effective (ed) increase of 2.69 and 3.51 times respectively compared to the initial numbers. The carrying capacity of the different organic matter... |

The worm Eudrilus eugeniæ is a species adapted to tropical climates and is highly demanded as fishing bait, therefore possessing high economic value. Separation of worms from humus is typically performed by manual, mechanical, behavioral and electric methods. The objective of this study was to characterize electric pulses for separation of worms (Eudrilus eugeniæ) from humus. To determine separation efficiency of worms from humus, a controlled pulse generator was used with frequencies of 1 and 5 Hz, voltages of 100 and 200 V, peak widths of 2, 3 and 4 x 10-3 s and exposure times of 15 and 30 min. The electrical pulse characteristics which resulted in greatest separation efficiency were: 1 Hz, 2 x 10-3 s and 200 V; and the maximum displacement index was... |
