Grain buyers’ falling numbers tests are finding evidence of pre-harvest sprouting

A wet fall across the Prairies provided the ideal conditions for pre-harvest sprouting in cereal crops. As a result, falling numbers tests have come to the fore as a quality assessment tool for buyers, with some grain companies performing a falling test on all wheat samples before purchasing. While, for the most part, harvest conditions were the […] Read more

The falling numbers test estimates the amount of sprouting in wheat, barley or rye. It measures the amount of alpha-amylase, an enzyme important in germination, which is present in the grain.


Four ways to avoid low falling numbers in grains

How accurate is the falling number test?

1. Harvest as soon as possible Try and harvest wheat as soon as possible after maturity. The longer it stays in the field once mature, the higher the risk of sprouting if it rains. On the other hand, don’t harvest too early — green kernels can have high alpha-amylase content to provide fuel for grain […] Read more

Grain grading revamp may add falling number, DON as factors

Two significant grain specs that aren’t yet factors for a crop’s official grade are now under consideration to join that official list.
