The role of micro-organisms in the composting process for the formation of organic fertiliser products is fundamental. It is a complex succession of populations of micro-organisms that degrade organic matter, thus returning a medium rich in mineral nutrients.
The most numerous micro-organisms in the composting process are bacteria with a high rate of metabolic activity, in particular Pseudomonas fluorescens, which is responsible for the stimulation of root growth and protection against pathogens.
Bacteria of the genus Actinomycetes are abundant in compost as they have the enzymatic capacity to degrade organic compounds such as lignin and cellulose.
Another group of microorganisms present in composting are filamentous fungi participating in the degradation of organic matter due to their lignocellulolytic capacity.
Micro-organisms in their active or inactive states make up a useful portion of compost and organic fertiliser products.
Liquid humic acid compost fertilisers are essential for maintaining the health of living agricultural soils.
It is made from Leonardite and Worm Humus, and is applicable both directly to the plant and in soils. Among the benefits of humic acid are increased assimilation of essential plant nutrients due to root growth and greater stability in fruit formation.
