Getting the Most From Your Fertilizer Dollar

Fertilizer consumption in the U.S. has been on a relatively flat plateau for the past 30 years. Until recently, increases in prices were relatively modest and slow.

Higher prices should prompt everyone to review management practices to get the greatest benefit from added fertilizers. Here are some general principles for optimizing fertilizer efficiency; local conditions will vary and may require consultation with a Certified Crop Adviser for your situation.

Soil Sampling: One of the keys to getting the most from applied fertilizer is to know exactly which nutrients are lacking and what amount is needed to bring them to non-limiting levels. Applying only what is needed will save money compared with putting a blanket application across the entire farm. Consider sampling the soil for available nitrogen (N) before fertilizing this year in order to adjust for existing nutrients in the root zone.
