BioStar™ Organics produces a wide variety of high-quality organic fertilizer products that are the best of all choices of organic vegetable fertilizer. Our patent pending technologies have taken common poultry manure to a level not seen in the organic fertilizer marketplace. They are produced using revolutionary technologies that benefit farms, their local communities, and the greater eco-system as a whole.  All of our chicken manure organic fertilizer products are pathogen and harmful bacteria free, OMRI certified and approved for use on food crops, including fruits and vegetables, because the BioStar anaerobic digestion process destroys the pathogens in manure.

Most liquid organic fertilizers are not approved for use on Tier 1 fruits and vegetables that go straight from the farm to your table within 90 days of harvest, but BioStar Organics fertilizers are OMRI listed for use with no restrictions! We produce liquid and granular fertilizers, fast-acting and slow-release nitrogen fertilizers, as well as an organic liquid soil conditioner that is a complete package of nutrients, and an organic/synthetic high nitrogen lawn fertilizer. You can read a summary of all of our organic fertilizers, or view product sheets for all of our types of organic fertilizer products.

RECOMMENDED TOMATO APPLICATIONS

Determinate vs. indeterminate tomatoes

There are two basic tomato types; determinate and indeterminate which will affect the amounts of organic vegetable fertilizer used per season. Indeterminate tomato types are also known as vining tomatoes. These tomatoes will continue to grow in size throughout the season, until killed by the first frost. Determinate tomato types grow to a fixed size. The growing season for determinate types is 65-70 days while indeterminate are 70-80 days.

An average program for conventional production of tomatoes using synthetic fertilizers is as follows:

  • Pre-Planting:
    • 40-60 lbs. N/acre.
    • If soils have a high CEC and are organic, 40 lbs. N is recommended
  • Post-planting:
    • First fruit cluster (dime size) = 3-4 lb. N/week
    • Fruit clusters at dollar coin size: 6-7 lb. N/week
    • Peak to end of harvest: 3-4 lb. N/week.
    • Determinate types = 45 – 50 lbs. N/crop
    • Indeterminate types = 50 – 60 lbs. N/crop
  • Average amount of synthetic fertilizer would be 50 lbs. N/acre or 88 gallons/acre/season

Synthetic vs. Organic Fruit & Vegetable Fertilizer

Since organic sources of nitrogen will greatly reduce losses from the soil system compared to synthetic, recommended levels of SuperSix organic ammoniacal nitrogen fertilizer should be approximately 20% lower than with synthetic, conventional programs. As such, a range of 30-40 gallons/acre/season of SuperSix is recommended, depending upon soil type.
