Healthy soil drains well and warms up quickly
in the spring
This allows for even germination and increase in activity of the microbes. Moisture from winter snow and early spring rain are valuable both at germination and later in the growing season so soil structure and conditions should facilitate the retention of moisture throughout the growing season. An interesting note – aerobic bacteria play a large role in the production of ammonium nitrate, which has a unique quality in that cools when heated and warms when cooled. Having adequate amounts will regulate the soil’s temperature year-round.
Healthy soil does not crust after planting
The aerobic zone is an interface between the atmosphere and the earth. The action of ‘breathing’ occurs when barometric pressure increases and decreases. Removal of the crust allows the soil’s aerobic zone to take in air and release carbon dioxide.
