The paper presents one of the ways to utilize the nutrients from the barn ventilation emissions for additional sub-soil fertilizing of flowers grown in an indoor plant growing facility. To investigate the effect of ventilation emissions on the growth and development of floricultural crops, a barn for 160 cows was connected by an air duct with a glass house, where marigold flowers (Tagetes) were grown. The air from the barn (ventilation emissions) was pumped to the subsoil layer in the greenhouse. The investigation outcomes showed that the additional subsoil fertilizing of flowers with ventilation emissions from the barn under the set conditions provided in average 137 % higher number of marigold flower stalks over the reference.
