Bioinputs for Vegetable Production in the Andes
The Andean region is characterized by multiple ecosystems with different climatic and geomorphological conditions that have generated great genetic diversity. These ecosystems have suffered deterioration, among other factors, due to the excessive use of agrochemicals, creating alterations to the environment and human health.
It is estimated that 40% of the soils have been degraded and erosion, among other factors, has contributed to the soils having less than 2% organic matter, low microbial activity, low moisture retention, low nutrient availability and high levels of pathogen infestations. The project seeks to restore agro-ecosystems with technological alternatives based on local resources (bio-inputs).
In this framework, the CIP contributes methodologies for the extraction and evaluation of microorganisms, as well as mass multiplication techniques. This knowledge is transformed into technologies by the PBA Corporation and the PROINPA Foundation.
The goal is the development of homemade techniques for the production of biofertilizers, bioinsecticides and biofungicides, based on local agricultural micro-diversity, the process of which will be strengthened with the construction of a pilot plant for the production of bio-inputs. The biological function and efficiency of native microorganisms in the laboratory, greenhouse and field will be characterized, and evaluated. If necessary, private investors will be linked to strengthen the development.
The technological solution
There is a growing concern for the use and abuse of agrochemicals in the Andean region and in particular for the deterioration of the soils that support millennial production processes. The latter have suffered erosion, loss of organic matter, low microbial activity and low water retention capacity.
In this framework, the goal of this project has been the search for nature based solutions based, in particular the development of biofertilizers, biofungicides, biopesticides and growth promoters. The alliance between three organizations with proven capacity and direct links to family farmers allowed validating new products with the potential to replace traditional ones generated by chemical synthesis. Most of these products can be produced locally by communities or small specialized companies.
The CIP established a germplasm bank with 171 strains identified at the molecular level along with isolation protocols for each microorganism; It also developed evaluation tests for biofertilizers and bio-fertilizers. A total of 60 strains were selected which were evaluated in vitro, in potato seed and in other crops (corn, lettuce, radish, chard, and spinach). Four strains showed remarkable results in adaptability, growth and yields.
Techniques for the production of bio-fertilizers were also validated and three types of biols that generate higher yields were identified. For the production of biopesticides, 171 strains of antagonistic organisms against phytopathogenic fungi were isolated in vitro, and test protocols were also designed, all of these were disseminated among the project's member countries.
CORPORACIÓN PBA carried out the same series of tests, collaborating in the development of technological innovations that allow producers to become independent from the use of chemical fertilizers. The project followed the Participatory Innovation (IP) methodology, which facilitated the execution of activities with producer organizations.
As in other projects of similar calls for proposals, the quantification of direct and indirect beneficiaries was not requested. However, it is estimated that the benefits reached a large number of producers, community organizations, research and development institutions and consumers.
