ESTIMATED CAPACITY OF RESERVOIRS (IN LITRES)
MOISTURE CONTENT ON DELIVERY
Grain is seldom sold at the standard moisture content.
When the moisture content is greater than the standard,
the weight of the grain is discounted to make provision
for the additional moisture.
The following moisture content standards are used as
condition for the delivery of commodities at silos:
Delivered Agreed standard
Sorghum
Wheat
Maize
Soybeans
Sunflowers
Groundnuts
Canola
Barley
Oats
For example:
Maize is delivered at a mois-
ture content of 14%.
Formula:
(100% - delivery %)
(100% - standard %)
= (100% - 14%)
(100% - 12,5%)
86%
= 87,5%
= 0,9828
By multiplying the weight of the grain
delivered by 0,9828, the weight of the
maize is calculated at a moisture content
of 12,5%, for example the weight of a
load of maize of 32 000 kg delivered at
14% moisture is (32 000 kg x 0,9828)
31 449,6 kg @ 12,5% moisture content.
