How much Residue do I need to increase my Soil Organic Matter levels?
Converting crop residue and compost to Soil Organic Matter (SOM). It ain't easy!
These are estimates only!
This is under development (Beta)
Part 1: What's our weight of soil and new SOM needed?
1. Enter the depth of soil to consider (inches):
(most organic matter is in the top 6-8")
2. What is the Bulk density of the soil? :
(Common values: Sand 1.6; Silty Loam 1.4; Clay 1.1 g/cm3)
3. How much do you want to increase SOM by? (%)? :
(note that a 1% increase can take 10 years)

What's our volume of soil in 1 acre to the depth you said?:
What's the (approx) weight of soil in that volume?:
So we need an additional
lbs SOM/acre to increase SOM by
More than likely many gardeners over-fertilize their gardens. You can change SOM, but not texture
Fertilize responsibly, build Soil Organic Matter.
A good way to build soil health.
