One solution for clay soil is to build a better
bed on top of it! In the "Quick Fix for Poor Soil" story
in issue 66, I shared an easy way to build a berm to rise above
problem soil. This calculator will help you figure out how much
soil and compost to buy to mix together for the berm and also how
much mulch you'll need to top off the finished berm. The amounts
for the mulch are calculated for a 3-inch-thick layer.
Fill in the measurements below for the bed you'd like to build,
then click “Calculate.” The amounts you'll need, whether
you buy by the bag or in bulk, will show up in the table below.
