Part 1, Section 2: Soil Fertility Management
Soil Fertility Management
Soil testing may be used to determine plant nutrient needs for a future crop or to aid in diagnosing production problems in a growing crop. The sampling guidelines to use for diagnosis are the same as those given above, except that the area represented may be smaller. Collect a minimum of 8 to 10 cores, even from a small area. It also is important to collect separate samples from both the problem area and a nearby area of “normal” growth. Test results may be used in a comparison to help identify the problem.
