Plant Health
The old adage ‘You can’t fix a problem if you don’t know you have one’ underpins the basic science of diagnosing plant diseases and nutrient deficiencies. For years, farmers and scientists have worked together to identify a set of visual clues that can be used to determine diseases and nutrient deficiencies in a variety of agronomic crops. These clues and symptoms can be extremely useful, especially when soil and plant tissue testing methods are neither feasible nor available.

Key Resource2002-01-01 Acidification of soil is a natural process with major ramifications on plant growth. As soils become more acid, particularly when the pH drops below 4.5, it becomes increasingly difficult to produce food crops. As soil pH declines, the supply of most plant nutrients decreases while aluminum and a...
