Killing the fungi and bacteria in the soil would do the most harm to the productivity of a garden. Fungi and bacteria are essential components of the soil food web and play a crucial role in breaking down organic matter and releasing nutrients for plants to use. Without these microorganisms, the soil would become depleted of nutrients, and plants would not be as productive. Killing nematodes and insects would also have a negative impact, but not as severe as killing fungi and bacteria. Adding humus and sandy loam to the soil and plowing in last year's crop stalks would actually improve the soil's productivity.
