On-Farm Recipe Trials and Yield Impact from fermented compost (bochasi) for vegetables


The first year of the project we perfected the recipe and method of BC production. We used three raw ingredients- leaves, methane dairy digester solids, and kitchen scraps to produce 3 batches of BC. 

A basic compost analysis (C6 – OM,Carbon, C:N, pH, Salts,S,Ca,Mg,Na,Fe, Al, Mn,Cu,Zn, NH4) was run on all three batches to compare.

See below A and L Lab Analysis of the three types of bokashi compost.

2015 3 Receipes compost analysis


Objectives/Performance Targets

Dr. Hoagland’s lab amended potting mix with the amendments (bokashi kitchen scraps, bokashi leaf litter, bokashi methane digests, or vermicompost) at a rate of 10%, 20% or 30%, and planted basil cv. genovese.  Interestingly the leaf 10% and vermicompost 10% are both significantly greater than the control. And check out what happens to the leaf bokashi as the rates go up.  More analysis is being conducted and another round of rates and bokashi will be tested in 2016.  See chart below.

Judith_chart summary


Completed three recipes.

Conducted compost analysis

Completed one greenhouse growth study.

Impacts and Contributions/Outcomes

It appears that the leaf compost will be our best recipe for both yield impact and ready material we have available.

We will repeat in spring 2016 and run a full compost analysis on chosen recipe.

Yield studies from field yield studies in 2016 will further test impact of bokashi.
