How Biovin works
The process of “Regulated Grape Mark Composting” allows the humification of grape mark which is available in large quantities as a by-product of grape-juice-making. The fermentation process is started by inoculation and regulated by temperature and air flow in a solid sate fermentor and ensures a succession of microorganism (Streichsbier et al., 1982*) starting with yeasts which, by autolysis and subsequent binding of the residual alcohol by esterifying reactions, enable rapid appearance of a mixed population of bacteria. The temperature increase continued by this bacterial flora favours growth of a thermophilic fungal flora (dominated by Thermomyces sp.) which is mainly responsible for the decomposition process. In the last phase a mixed population of Streptomycetes and other Actinomycetes is taking over and is finalizing humification with an additional production of plant growth hormones (see analysis) The fermented product is dried and granulated and can be stored for several years without losing quality.

BIOVIN BINDS NITROGEN / NITRATES IN THE SOIL
Nitrate leaching in sandy soilsStudy of the Institute for Microbiology, University of Innsbruck, Austria: 0,3 gram of total nitrogen was added to 300 g of non sterilized sandy natural soil either as soluble NPK fertilizer (2 g of 15:5:18), Primafert organic fertilizer (4 g of 8:2:4) or as Biovin (10 g of 3:1:3) Soil was packed into cylinders (3 repetitions, each cylinder 10 cm wide, 30 cm long) and grass was seeded. After 3 weeks the leaching process was started by watering with 200ml de-ionized water. Thereafter the watering was repeated at times indicated.

LIFE+ Operación CO2
During the Life+ project Operation CO2 both agroforestry areas have each been divided in 3 plots with different levels of mycorrhiza and biovin added (0, 50% and 100%). Teams of Plant Health Care and Beral show how they analyse root development at the Ayoó de Vidriales area.
