How does the specific nitrogen-to-carbon ratio found in composted organic matter change the soil's ability to hold moisture during a prolonged drought?

Compost is made of carbon, which acts like a sponge, and nitrogen, which feeds the tiny bugs in the soil. A good balance between these two is called the carbon-to-nitrogen ratio. When you have a lower ratio—meaning you have enough nitrogen to help microbes break down the carbon—you create a substance called hu....
