Healthy to Harvest High-Yield Corn Program

The US corn crop is in trouble, and each year the problems seem to increase. Bio Minerals Technologies has introduced a Healthy To Harvest program that can help reduce many of these problems, providing corn farmers with harvests of up to 300 and potentially 400 bushels per acre, without significant disease or pest losses. Best of all, we can do it naturally to help you reduce your chemical dependence and chemical inputs (not to mention chemical bills).

Watch the video below for an introduction and overview of our Healthy to Harvest program. The details of the program are outlined below the video.


Shooting for 300 or even 400 Bu/A of nutrient dense corn.

Soil and plant health does matter and is crucial to success.

‘Let your food be your medicine.’- Hippocrates

In order to maximize your crop yield, it is important to understand the plant's nutritional needs. As you can see from the chart below, different elements are required in varying amounts throughout the corn growing cycle.

The nutrient volumes shown in the chart reflect a yield target of 400 bushels/acre. If your yield target is lower, your nutrient requirements will also be lower. You can contact Bio Minerals Technologies for custom nutrient requirement calculations based on your field's yield targets.

The table below provides a quick outline of the Healthy to Harvest program with greater detail in the following sections.

Cover Crops

Apply compost or Bio-augmented manures


  1. Test soil compaction with penetrometer: above 300 psi roots are restricted, test during the fall season.
    1. Ameliorate with inline deep tillage to needed depth; adding biology w/food into the soil will increase soils porosity, tilth and reduce re-compaction. Microbes need oxygen as well as a carbon-based food source.
    2. Apply Gypsum if the Mg base Saturation percentage is greater than 15% (KAS test).
    3. Plant cereal rye or multiple species cover crops to increase soil porosity and increase microbial species and populations (planting is typically the fall before; termination cover crop is spring).
  2. Update old soil tests; include Base Saturation levels and micro-nutrient levels. Determine the best methods of application.
    1. Designate several representative fields for soil analysis using the Haney Test or Biological test (Earth Fortification Labs – Corvallis, OR).
      Another sophisticated test is that of PLFA or poly lipid fatty acid. This types the microbes into different categories. (ie: ciliates, flagellates, amoeba).
    2. If sulfur is needed add ammonium sulfate (AMS), Gypsum, or Elemental Sulfur to meet nutrient demands for yield goal. 90% of Sulfur is needed post tassel.


  1. Apply Bio Minerals Technologies Dry Seed Treatment. Our Seed Treatment contains 12 groups of highly beneficial microbes such as Azotobacter than fix N, mycorrhizal that fix P, pseudomonas, bacillus, trichodermas that fights pathogens and many more; includes 75 or more micronized minerals for better germination. Application rate is 1 oz per acre (20-25# of seed).
    1. Apply micro-nutrients (Zn, Cu, Mo, Mn, B, Fe) to increase germination, vigor, early growth and nutrient uptake to the seed, or apply in-furrow.
  2. Stabilize the P in liquid starter fertilizer using Bio Release. 1 gallon Bio Release will stabilize up to 12 gallons of 10-34 or 11-37 type products. Maximum rate of 8 gallons 10-34/11-37 in furrow per acre.
    1. Apply 1 gallon Bio Release per acre, in furrow, with the appropriate amount of liquid P (and other nutrients) to meet the needs of the crop and to supplement soil shortfalls.
    2. Apply 1 gallon FLC per acre.
      1. Apply 1/2 gallon per acre in furrow with seed and starter fertilizer.
      2. Apply 1/2 gallon per acre with the N applications as a side dress, banded away from the seed or injected through irrigation. If applying liquid N several times, split the remaining 1/2 gallon of FLC accordingly. The FLC will help stabilize the nitrogen and slow the release as well as reducing leaching. If only dry N is used, put 1 gal FLC in furrow at planting.
    3. Apply 1 pint Zn 9% in furrow at planting with starter. Another pint of Zn 9% can be applied in the side dress later, or if no side dressing, apply 1 quart Zn 9% in furrow at planting.
    4. Fine-tune N program to where application timings match periods where uptake is high. Apply 10-15 gal of 32% in 2 X 2 or side dress for early root uptake. Stabilize to keep more in the ammonium form. With liquid N, use up to 2 oz Mo/ acre.
  3. GMO vs Conventional considerations
    1. GMO: There are many genetic alterations in these varieties, some of which increase the plant’s sensitivity to salts. This requires that we reduce the amount of liquid phosphate (due to the N percent) in furrow with the seed. Depending on soil P levels, 10-34-0 or 11-37-0 could range from 2-3 gallons to not more than 4-5 gallons/acre. This means supplemental P, dry, might need to be applied fall or spring to help meet crop demand throughout the season. Other liquid phosphate products will vary depending on N-P-K percentages.
    2. Conventional: These varieties are not as sensitive to salt. This could allow us to increase the amount of liquid P stabilized with Bio Release per acre. This will be based on existing soil P levels and salts (N not to exceed 10#/acre) that can go in furrow with the seed without causing damage to either germination or seedling development.
  4. Plant when soil temps are on the rise and are near 55 degrees or higher. Make sure the soils are dry enough to allow traffic without causing more soil compaction.

Post Emergence

V3 – V5

  1. After emergence, tissue test to verify sufficient P at .42 ppm or higher.
    1. Apply post emerge herbicide. Conventional herbicides create fewer mineral deficiency problems. If any Round Up herbicide is applied add 1 quart of Glyphonix.
  2. Tissue sample and analyze leaf samples at V5-V7 for micros. Include Moly in some of the analyses since it is deficient 95% of the time and is crucial for N uptake and use efficiency.
    1. Soil application of N and S as needed – AMS/Gypsum.

V8 – V12

  1. First Foliar:
    1. If early dying corn has been common or you see caramel colored lesions on the lower stalk apply 16 oz/ac of Bio Empruv for Goss’s Wilt.
    2. Apply Foliar Micro Boost at V8-V12 at 32 oz/ac with 16 oz/ac of Bio Release. Be sure Co is included plus Mo where soil test levels are low. Another round of tissue sampling may be needed.
    3. If second application of Round Up herbicide is applied, use 1 quart of Glyphonix.
  2. Apply 28% or 32% nitrogen side dress with Y drop or coulter applicator, stabilize N with FLC. Add 2 oz Moly to facilitate uptake of any applied N. You can use a total of 4 oz Mo throughout the season in the soil with your N. 46% dry Urea can be treated with something like Nutrisphere, a N stabilizer, that does not work by killing soil microorganisms. This will help keep the N in the ammonia form at tassel to help combat the Clavibacter bacteria. Apply dry with a tall tired dry box spreader. When applying dry N, apply 2 oz liquid Moly as a foliar.
  3. Scout for insects (corn borer, corn root worm)
    1. Check for CRW (corn root worm) feeding weekly if the field has a history of root worm feeding or beetle counts the previous season were >1/plant. If feeding is occurring at V8-V10 apply Safestrike (from GreenSpire Inc, Des Moines, IA) as a foliar.
    2. Scout fields for insect damage. Fields planted to conventional hybrids need to scouted for ECB by an examination for shotholing of unfurling leaves with the first brood. The second brood typically reaches higher numbers and is detected by scouting for the small fish scale appearing egg masses on the underside of the five middle leaves next to the midrib. Spray if the infestation reached the published treatment thresholds: If 25% of plants show shotholes from the first brood in mid-June; Second brood, in late July to mid August, treatment is needed if 15 to 20% of the plants hold egg masses.

V15 – V18 (Pre-tassel)

  1. Apply foliar one week before tasseling to add energy to the plants for pollination and fertilization.
    1. Apply Foliar Micro Boost at 32 oz/ac with 16 oz/ac of Bio Release. Be sure Co is included plus Mo where soil test levels are low.
    2. Include 16-24 oz of Bio Empruv as a foliar to maintain a high level of plant health and lengthen fill time by 20 to 30%.
      Note: If the 16 oz of Bio Empruv was not made at V8- 12 application use 32 oz Bio Empruv pre-tassel V15- V18. This timing will permit most high clearance sprayers to make this application without getting the radiator plugged with pollen sacks or having the boom too low. Bio Empruv is totally systemic and lasts 2.5 to 3 months. It is also non-toxic and creates no neurological hazard.
    3. If Corn Borer threat exists and economic thresholds are reached, add in an insecticide or deterrent with the foliar mix.
    4. Apply 1 gal/ac ammonium-based N w/slow release as a liquid foliar (21% N) tank mixed with the foliar. This would be Pt-21 or Kugler’s KQ-XRN.
    5. Apply 1 gal Fish Hydrolysate / acre as part of the foliar; it provides amino acids and additional nutrients which will help increase bushels / yield as plant moves into reproduction. The amino acid form of N is much more efficient at this stage of plant growth than elemental N sources. You will achieve more bushels of corn using less actual units N.

Post Harvest

Apply 3 to 4 quarts Bio Release to corn residue with at least 15 gallons of water and lightly disk into the soil for fall/winter/pre-planting decomposition of crop residue and pathogen reduction. Consider setting up a tank equipped with an air pump and a brew bag filled with our Pretreated Humus, using Bio Release and Huma Phos minerals to make your own mixture of Microbial Mineral Tea to aid in the process of residue digestion and pathogen control. This same mix could be used as the liquid carrier for planting time or in-season applications. Two applications over two seasons have shown they can raise Haney scores into the low teens. Recipes for Microbial Mineral Tea and brewing equipment details are also available on our web site.

(Note: When making Microbial Mineral Tea using Bio Release, Pretreated Humus, and Huma Phos, the post-harvest Bio Release can be reduced to 1-2 quarts/acre with 15-20 gallons of Microbial Mineral Tea.)


Bio Empruv is not a ‘silver bullet’ approach to disease or fertility management. Bio Empruv is part of a well-managed crop nutrient program that can increase the plants ability to withstand disease and increase yield and quality by living to maturity and filling the kernels with minerals and nutrient density. Bio Empruv will not replace minerals if they are not adequate for a desired yield. Bio Empruv can support mineral utilization but those necessary minerals must be available for the plant throughout the growing season to continue growing to maturity and filling kernels. Bio Empruv is not an insecticide or a pesticide, it is a biological product that can help boost the plant's immune system and help sustain plant functions.

Bio Empruv is effective only on gram positive bacterial pathogens such as Goss’s Wilt (Clavibacter Michiganensis Nebraskensis) and others. Bio Empruv is not effective on gram negative bacterial pathogens such as bacterial stock rot (Erwinia). For longer lasting fungal pathogen infections, consider our O2-YS line of chitosan-based products.
