Major Breakdown

Major Breakdown is a targeted microbial blend built specifically to accelerate crop residue decomposition, featuring six specialized strains at 15 billion CFU per gram. Led by Bacillus licheniformis, a proven cellulose and lignin degrader, this formula works alongside key Bacillus and Paenibacillus strains to break down tough stalks and stubble while recycling locked-up nutrients back into the soil. Apply post-harvest or ahead of planting to speed up residue turnover and improve seedbed conditions. Major Breakdown puts the biology to work so last year’s crop fuels the next one. 

  • Complete residue breakdown: Diverse enzyme profiles for organic matter decomposition
  • Enhanced resilience: Multiple stress tolerance mechanisms
  • Produces plant growth-promoting hormones (auxins, gibberellins)
  • Comprehensive nutrient mobilization: Multiple mechanisms for P, K, and N availability
  • Tolerates harsh conditions (high temperature, alkaline soils)

Application Directions

Add the contents of the 3lb container to 275 gallons (50 ac-4.5oz-2 scoops, 80 ac-7oz-3.5 scoops, 100 ac-9oz-4.25 scoops) of Earthquake Liquid Humic, Sweet-N-Loam, or Shug Nitro (it is compatible with other Sugar Creek Ag products as well, ask your representative) and mix thoroughly with a chemical mixer. Major Breakdown accelerates the decomposition of crop residues including corn stalks, wheat straw, turf clippings and other plant materials Apply to residue immediately after mowing, harvest or during fall tillage. Application of mixed product can be made according to the instructions on the label of the product being mixed with. Foliar spray or drench the residue being treated utilizing the application rates of the product it is mixed with. Major Breakdown can be mixed and used with other agricultural chemicals, for which mixing is permitted by the product label. If such a mixture is planned, a compatibility test should be first conducted. Avoid mixing with quaternary compounds, Peroxyacetic Acid (PAA), or similar type broad spectrum biocides or fungicides. Once blended the finished product should be used as soon as possible.
