Organic products in liquid form with a high content of beneficial microorganisms and nutrients, are beginning to be used in agricultural activities to restore the microbial flora that should be present in the soil and provide nutrients to plants, within these organic products in liquid form we have the compost tea and biofertilizers based on microorganisms both will help plants to assimilate nutrients that are normally blocked in soils.
▶ The use of organic products as fertigation, compost tea applied on leaves is used as a quick source of foliar nutrition, inducing physical modifications of the leaves that inhibit the germination of pathogen spores and promote antagonists, beneficial microorganisms that compete against pathogens.
In the preparation of Compost Tea, an extract should be made in water at 15-20% and applied every ten days according to the needs of foliar nutrition. A mixture consisting of 90% water plus 10% compost is made.
For example, in a 200 liter drum, a bag of compost is introduced at a rate of 20 or 30 kilos, completing the drum with water and leaving it to ferment for 4 to 6 days. The bag should be pressed periodically so that it has adequate oxygenation and can reproduce the beneficial microorganisms of the compost.
As for the preparation of biofertilizer based on microorganisms, they are products based on beneficial soil microorganisms, microbial strains can be added to help fix and enhance nutrients, especially bacteria and fungi.
Basically microorganisms that live in association with plants, biofertilizers can be solid, with a loose structure, or liquids being prepared from water and various materials such as molasses, milk, manure, etc., which are left to ferment in a drum for several days.
