Efecto de la Utilización de Aserrin en la Combinación con Estiercol Bovino "Como Sustrato en la Producción de Humus de Lombriz (Eisenia Foética) Lombriz Roja Californiana"

Abstract

In the Chimborazo province, Lombriculture and Organic Manure Unit, Cattle and Livestock Science Faculty, ESPOCH, the effect of the sawdust use combined with bovine manure as a feed to produce worm, Eisenia foétida, humus (red Californian worm) was evaluated. The experimental units consisted of 12 of 1m x 1m x 0,5m litters distributed the control treatment. The sawdust levels were: 100% sawdust + 0% Bovine manure, 75% Sawdust + 25% Bovine manure, 50% sawdust + 50% Bovine manure, common organic matter or 0% sawdust (control). The results permit to conclude the effect of the ground sawdust in feeding worms was positive when using a combination of quality and fertilizing substrate conversion time. It also was demonstrated that upon using sawdust at 100% these annelids reproduced slowly, the substrate-fertilizer conversion lengthened at 150 as a low-quality product, low reproduction considering time and minor biomass; the was no profitability; this is why it is recommended to use ground sawdust for substrates in lombriculture up to a proportion of 50% sawdust combined manures the other one because of the fact that good productive parameters are attained, the substrates improve their relation C/N, the manure increases the sawdust degrading and the management and harvest become easier.
