When planning
to store in plastic bags, it is recommended that the following
guidelines relating to moisture content and storage periods
of time be followed: |

Guidelines for
Storing Dry Grain in Plastic Bags |
|
| |
Evaluation
of risk takes into consideration the moisture content
of the grain at the time of bagging, the normal aging
process of the bag, and the possibility of the bag being
damaged by external agents. As the outside temperature
ascends, the risk for the grain increases; when there
is a high presence of foreign matter and impurities, the
risk increases; when there is mechanical damage to the
grain, the risk increases. These are general guiding principles,
and the variables involved cannot be easily quantified
or given absolute values.
The important principle to bear in mind is that checking
the bags and its contents regularly is of the utmost importance.
Adequate monitoring will ensure that if any anomaly is
detected, corrective action can be taken at an early stage
to preserve grain integrity. As an example of one practical
upshot of proper controls, the grain that is damp, that
has the higher moisture content, that is damaged or that
contains the most amount of foreign elements and impurities
should be the grain that is sold off first, while grain
that is dry and clean can be put up for sale at a later
date. |

So
remember: this is a simple technology requiring care at
every stage to preserve the quality of the grain
