Garden with Insight v1.0 Help: elemental

When we say elemental nutrients, we do not necessarily mean they are in the soil in their elemental form. Often we mean that they are incorporated in large molecules so various we have no interest in simulating the amounts of the specific substances, so we simulate only the mass of the atoms in which we are interested. We can speak of the elemental mass of oxygen in water (H2O): it will be 16/18ths of the total mass of the water (because oxygen has an atomic mass of 16 and hydrogen of one). Elemental nitrogen, phosphorus and carbon are spoken of in the simulation in a similar way.

How it works:
nutrient cycling
