La eficiencia del uso nitrógeno (EUN) por los cultivos agrícolas es muy baja pérdidas asociadas con su alta solubilidad y, en algunas condiciones de suelo, volatilidad, lo que trae como consecuencia impactos negativos la rentabilidad económica y contaminación medio ambiente. Se realizó un experimento campo bajo riego suelo Bajío Guanajuato, México para estudiar asimilación fertilizante nitrogen...

In laboratory studies performed in the United States and Hungary, the dump fly Hydrotaea aenescens (Wiedemann) was reared successfully in manure of 1- to 8-wk-old dairy calves, and in manure from adult lactating dairy cows. Survival in manure collected from 1-wk-old calves was poor (7.2%), better in manure collected from 2- and 3-wk-old calves (53.5%), and best in manure collected from 4- to 8-...

The circadian clock is an endogenous regulation mechanism that coordinates biological processes with daily changes, which are regulated by genes. Bmal1 and Period key genes their roles in reproductive development have been widely studied. spawning time of Sinonovacula constricta limited to the night even under external artificial stimulation, it might be internal clock. In this study, heart rat...
