Safe storage guidelines

مشاركة بواسطة عبد الرحمن الجارحي »



Producers can use the following charts to prevent spoilage of stored grain
How to use the charts:

Measure the moisture content and temperature of your crop as it goes into storage.
Plot this initial moisture content and initial temperature on the chart. If the result falls in the no spoilage zone, then your crop should store safely for up to 5 months, 6 months in the case of wheat. If it falls in the spoilage zone, spoilage will occur.
Cool or dry the crop in storage until the temperature or moisture content put it in the no spoilage zone.
The centre zone cuts off a 1% safety margin although spoilage may occur under these conditions.
Be aware that the moisture content and temperature of a bulk may change during storage due to convection currents, leading to localized spoilage. Monitor the top- centre of the bulk regularly throughout storage or use aeration.
Charts
Graphs outlining potential risk of spoilage of various grain commodities base upon initial temperature and moisture content. As moisture content and/or temperature increase so does the risk.

Barley
Beans
Canola
Flax
Oats
Peas
Wheat
Yellow mustard
