BioStar™ Organics produces a wide variety of high-quality organic fertilizer products that are the best of all choices of organic fertilizer for grape vines. 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 table grapes and wine grapes, 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.


Compared to wine grapes, table grapes require much lower amounts of nitrogen per acre since root systems are deep and there is a considerable amount of nitrogen stored in the root systems for use during the growing season.

Total seasonal amounts of nitrogen can vary significantly due to variety of grape as well as soil and cultural conditions.  Fertilizer rates for table grape vines range between 25 and 75 lbs. N/acre/season with synthetic soluble fertilizer for grape vines. 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 15-50 lbs. N/acre is recommended and split into a number of applications.

Fertilizer for Grape Vines Schedule

Nitrogen is needed most during the rapid vegetative stages of growth during the spring and during bud break to early berry development.

Post harvest applications of nitrogen are highly recommended for rapid and efficient growth the following spring. Up to ½ the total amount of nitrogen can be applied right after harvest in August or September.

Average usage of SuperSix as a fertilizer for grape vines would be approximately 40 lbs. N/acre/season or 70 gallons/acre.
