Garden with Insight v1.0 Help: Soil patch next day functions: calculate denitrification (nitrate to ammonia)

Denitrification is the conversion of nitrate in the soil to ammonia by anaerobic soil bacteria. Since anaerobic bacteria can only thrive if there is very little air in the soil, denitrification is only calculated if the ratio of soil water to field capacity is greater than 0.95. If any denitrification occurs, it is dependent in each soil layer on temperature in the layer (warmer = more), the amount of nitrate in the soil layer, and the ratio of organic matter to total soil weight in the layer (as an index of microbial biomass since microbes rely on organic carbon to survive).
