NEW BIO-FERTILIZER MADE WITH AGRICULTURAL AND AGRO-INDUSTRY WASTE

WASTE GOES INTO COMPOSTING, WHICH MEANS FIXING CARBON AND, THEREFORE, REDUCING THE EMISSION OF POLLUTANTS INTO THE ATMOSPHERE.

Our University’s Soils and Crops Technology Center (CTSyC) is planning to develop a liquid fertilizer that ensures the sustainability and care of the soil, made with agro-industry, agriculture and livestock manure waste.

The director of the Center, Hernán Paillán, explained that the idea was born precisely in order to protect the soil "so as to prevent it from losing its natural characteristics and become poorer. When the soil is healthy, it will produce healthy food, so this fertilizer will help good nutrition and will also collaborate in the care of the environment".

Its production includes the residues of crops, packing and manure from big livestock. The former represents one of the fundamental characteristics of the bio-fertilizer, since such waste goes into composting - will become compost -, which means fixing carbon and, therefore, reduce the emission of pollutants into the atmosphere.

"This bio-fertilizer supplements the normal management of organic fertilizing of a crop. It is applied to plants in liquid form through irrigation, thus feeding the bacterial flora present in soils and providing them with compounds to generate nutrients", added Paillan.

The proposed idea is backed by research and development in order to achieve a first prototype, and it includes an assessment of organic crops, and transferring the knowledge through workshops to farmers and public stakeholders.

One of the aspects that the CTSyC has taken into account in order to run the project is the increase of organic agriculture worldwide, as well as in Chile, in response to the need to reduce the levels of contaminants in the soil and the atmosphere. The purpose is to contribute to increase the supply of healthy food and respond to the growing demand from the national and international market.

The director of the CTSyC said that the bio-fertilizer can be certified as organic, because the components from which it is made are produced naturally, like vermicompost and manure.

In parallel, this initiative seeks to contribute to the sustainable and economic value of organic waste, which rather than ending up in a landfill, they have a productive purpose becoming the compost that feeds the humus-generating earthworms.
