The objective

What the trial set out to test

This trial examined the effect of an ABI microbial consortium on organic coffee grown under difficult conditions: three-year-old Castilla plants with high defoliation from radiation exposure, on loamy clay soil. The consortium was applied at an initial 2 cc per plant followed by 2 liters per hectare every four months, across 4,000 plants within a 5,400-plant lot.

Starting point

The baseline

The untreated plants showed heavy defoliation and uneven harvests with a high percentage of defects. For organic coffee growers, defoliation and inconsistent harvests are among the hardest problems to manage without synthetic inputs, and they directly reduce both volume and cup quality.

The results

What the consortium delivered

The treated plants showed vigorous growth with lush green foliage and dense clusters of green cherries, with visible improvement by 115 days after treatment and a 5.6% production increase over the previous year. Harvested cherries showed superior taste quality. The result points to healthier, more productive organic coffee from a single addition to the existing program.
