Every growing season is different, so there’s never a one-size-fits-all fertilizer strategy – even between your own fields. To get the best yield, it helps to let data guide you along the way, instead of relying on guesswork or doing what you’ve done in the past.
Let’s look at five ways to find and build the right nutrition program for your fields:
- Start with a Soil Analysis
A comprehensive soil test is how to start a successful nutrition program. This way, you get a clear inventory of what nutrients are presently in your soil.
Why it matters:
Without an accurate soil analysis, any fertility plan is based on estimation. Soil tests tell you the pH, organic matter, and Cation Exchange Capacity (CEC) of your field. For instance, your soil might contain plenty of phosphorus, but if the pH is too low or high, the plant can’t even access it. Knowing these baseline metrics allows you to correct underlying issues and select a product mix that takes care of actual deficiencies.
- Use data to set goals
Your nutrition program needs to match what you expect to harvest, which means setting targets for each field.
Why it matters:
A program designed for a generic yield average could possibly leave money on the table or over-apply inputs. By reviewing your five-year production history and accounting for the potential of your seed varieties, you can calculate what nutrients you need to reach your target. Discovering how to use your inputs is a great step toward creating a management plan.

- Analyze Records
Before looking forward to the next application, look back at your performance data.
Why it matters:
Evaluating yield maps and soil tests can show trends that a single year’s analysis might miss. If you have specific areas that are underperforming, look at compaction or drainage – is it that, or micronutrients? Spotting downward trends early can help you adjust your program during the growing season before these patters lead to more loss.
- Perform in-Season Tissue Sampling
By performing a tissue test during the season, you really get to see what’s happening with your growing crop.
Why it matters:
While soil tests show what’s available, tissue tests show what the plant is actually absorbing. Crops may be experiencing a deficiency that is limiting yield potential even before visual symptoms appear. By catching this early, you can do precise foliar or side-dress applications to help the plants through different growth stages.
- Work on Nutrient Availability, Placement, and Timing
As all growers know, you have to be efficient. Selecting highly available nutrient sources and placing them exactly where roots can access them can determine the success of your program.
Why it matters:
Traditional dry fertilizers often experience low first-year availability because nutrients tie up with soil particles. High-efficiency liquid options bypass these soil issues by remaining available in the root zone over a longer period. Using targeted starter placement or feeding nutrients throughout the season gives you the best way to improve your ROI.
Planning ahead
By combining accurate soil and tissue data with high-efficiency products, you can build a strategy that helps your crops reach their potential. You can also count on AgroLiquid to help.
