Soil Analysis

Posted: February 21, 2011 in Uncategorized

An important question about this composting unit is the quality of compost it is making and for what application it is intended for. So I took a sample of the final product (after letting it stabilize outside in a bin for 24 days) to a local testing lab. I told them the end use was intended for a community veggie garden. This is their response:

“Typical of most home compost solutions, the macro-nutrients are high while I would rate the micro-nutrients as being low. While I can appreciate the future for this compost being an incorporated additive for a mineral soil, currently deficient in fertility and organic matter, the excess of macro-nutrients and water-soluble salts will all be reduced from their compost alone status.”

I am not entirely sure how to interpret the last part of the sentence, but speaking with the lab over the phone it sounded like all I had to do was add some iron powder, mix it with a particular type of sand at a 1:1 volume ratio, and it was good to spread on the veggie garden. I guess the proof will be the cucumbers next year.
