Product Usage
Time + bugs/microbes = beneficial soil amendments,
but what's the best way to use them?
Compost
A chunkier material compared to frass, this is low N-P-K product that works to add microbes to the soil to build soil health and plant nutrient uptake and resilience.
A general application rate is 1 5-gal bucket per 100 square feet for light amending. Heavier application can be up to 10 5-gal buckets per 100 square feet if the soil is very poor and a new planting bed is desired. This heavy application rate is not recommended year after year.
Frass
A slightly higher N-P-K value means that frass can be used at a lower rate. As an insect-derived product, frass is loaded with microbes to help build soil and also chitin, which can trigger a plant to grow stronger to protect itself from nefarious pests.
A finer particle size allows for several application options: frass can be added to non-chlorinated water to create a root soak for any plants, but works really well in planters and hanging baskets. It can be broadly applied with a drop spreader. A general application rate is 1 pound (roughly 1 quart) per 20 square feet. It is also easily doled out with any scoop, shovel, container, etc.
Compost + Frass
Possibly the most beneficial combination of products, using both will give the soil the best of both worlds.
For poor soils, Starting a crop or plant with the combination of 1 quart of compost + 0.5 pounds of frass per 1 foot trench. Further top dressing with frass after 6 weeks is also a beneficial option.
