Our last video showed you how to do a soil test by taking a sample and preparing the soil for the test. It also walked you through the process of performing the soil test for nitrogen, phosphorus, potassium and soil pH.
This week’s video continues with how to interpret the results. It also shares detailed instructions for how to calculate your soil amendment quantities based on the results you obtained. It requires some math, so get out your calculator and work along with Christy.

Amendments we used:
- Blood meal (13.6%) for Nitrogen (we had a giant bag from years ago, and will use it up then switch to something vegan)
- Sea bird guano (11%) for Phosphorus
- Kelp meal (17%) for Potassium
Don’t let the process of calculating fertilizer quantities keep you from giving your garden what it needs. After you’ve done it once, you’ll know how to do it forever. Take this important step to ensure that you are adding the right amounts to your soil before planting this season. You won’t regret it.
