Speaker: John Lawrence, PhD, PE

Session Description

The safe storage moisture content of different hybrids of grains are not the same. This information is very essential to keep the grain safe in storage. The equilibrium moisture content characteristics of any grain gives information about the accurate safe storage moisture content at various grain temperatures. It also gives information about whether the current ambient air conditions will add or remove moisture in the grain mass. Hydrating soybeans gives economic benefits to farmers and producers.

Speaker of this session was John Lawrence.
