365 Program

Make The Most Of The 365 Program

This Program Wasn’t Built for the Average Grower

This program requires a commitment from you as a grower. The 365 program is most effective and built for those growers who desire a competitive edge. In order to make the most of this program and develop effective fertility management decision, you have to be willing to remain engaged in timely decision making throughout the growing season.

You’ll be met with equally committed agronomic experts and sampling technicians.

Crop Stages for Sampling:

  • Corn tissues pulled at V3-V4, V8, V12, VT, R2, and R4
  • Soil in corn is tested at V4 and V12
  • Soybean tissues pulled at V3-V5, R1, R2, R3, and R4
  • Soil in soybeans is tested at V4 and R2
  • Pull 2 soil samples per location in the field:
    • 3 cores at 6” in the furrow and 3 cores outside the row at 6”
  • Repeat this with a sample from 6”-12” soil in a separate bucket


Test Results You Will Acquire

Tissue samples will give you your levels of:

  • N, P, K, Mg, Cal, S, Fe, Mn, B, Cu, and Zn
  • These levels can be compared to previous years’ samples of what a 250-bushel, 300-bushel, all the way up to a 450-bushel corn would be at that growth stage
Soil tests results, including a Bray test and a Haney soil test will show your levels of:
  • P, K, pH, OM, microbial biomass, CO2 soil respiration, nitrogen available for uptake, and all other micros along with base saturations


Sampling Protocol

If you are sampling a location that is primarily flat, sample according to yield levels. For locations with a hilly landscape, try sampling according to soil type.

Pick a location in the field that:

  • Yields average to above average and not in a wet hole
  • Isn’t on too much of a contour
  • Represents more than 20% of the field soil type
  • Don’t forget to mark these locations with a flag and a GPS pin!


Tissue Sampling:

- Be sure to choose random samples from the top, most recent mature leaves of your crop. These uppermost leaves provide the best ideal plant sample.

- Too young or too old of plants many not correctly represent your plant’s nutrient level. Use only healthy tissue for your samples.

- Stressed tissues such as ones exposed to standing water or damage from disease or insects should not be used.

- For the lab to evaluate the tissue accurately, adequate amounts of plant tissues are essential. In order to be analyzed, the tissue is dried and ground, greatly decreasing its weight and mass. Visualize that the sample should be about the same size as a softball when balled up.

Only seal the plant tissue bag when it is packaged in the shipping container. This helps accelerate air flower to help drying time.

Try to collect tissue samples during the first part of the week. This allows time for the samples to reach the lab and makes for quick turn around for your results. If you can’t collect earlier in the week, store the tissue in a refrigerator to prevent deterioration and mold until it can ship on Monday.
