Thematic training material for the use of alternative biomass as fertilizer has been published

May 06, 2021

Altenative biomass refers to microalgae based biofertilisers from wastewater by heterotrophic microalgae process. It is a solid fertilizer (powder). Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Duckweed (the Lemnaceae) is a family of aquatic plants that rich in protein. Both of them can make use of nutrients in solutions to produce biomass by algae cultivation which can be used as crop fertilizer. With the use of microbial fertilizers obtained from microalgae, the amount of soil organic matter and the water holding capacity are improved and have positive effects on soil, plants and therefore environment. As an organic fertilizer, microalgae have the potential to prevent nutrient losses through a gradual release of N, P and potassium (K), which is attuned to the plant requirements.

Thematic training material for the use of digestate in Southern Europe has been published

April 29, 2021

Digestate is a fertilizer obtained from anaerobic digestion processes where microorganisms break down organic materials in the absence of oxygen. The anaerobic digestion consist in a series of biological processes in which the microorganisms break down the biodegradable material in absence of oxygen. The main end products is the biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas and fuels.
