NPK Fertilizer Brewery™ is an organic agriculture facility that converts biomass into organic liquid fertilizer.

The NPK Brewery™ is a portable facility for making fertilizer using a process called Nutricycling™. It is designed to entirely replace farmers need for mined and petrochemical fertilizers.

The NPK Brewery™ consists of a series of extraction vessels, and processors that receive biomass in one end and convert to a liquid fertilizer, suitable for in-ground farming and organic hydroponics, out the other.

Organic farmers, both soilless and in-ground, have the challenge of competing with conventional inorganic farmers who apply inexpensive chemical fertilizers by spray, fertigationor broadcasting. Organic farmers must either bear the labor of creating and applying the compost, or spend a good deal of money to purchase organic liquid fertilizers. Compost itself, provides a soil ‘amendment’, which has good properties for the soil, but with only modest nutrient concentrations of NPK; it is not rich enough to call a fertilizer.

There are 123 million households in the US producing 80 million tons of food waste and grass clippings per year. The annual use of nitrogen fertilizer for lawn care in the US is a staggering 3 million tons. At a retail price of about $3.50 per pound of nitrogen, the cost to consumers exceeds $21 billion dollars per year. On top of that is the cost remediate the environment as a consequence of the excessive use of fertilizer and unsustainable disposal of waste.

The Nutricycler™ and NPK Brewery™ provide a sustainable agriculture solution for hydroponics and in-ground farms. These systems allow growers to control the amount of dissolved organics in the finished liquid fertilizer.

    • More-organics fertilizer provides a carbon source for microbes in the soil or in soilless media beds.
    • Less-organic extractions are ideal for irrigation and as foliar spray fertilizers.

Soilless growers can use the plant-ready liquid fertilizer in DWC deep water culture systems growing lettuces or basil for example or in NFT nutrient film technique troughs with tomatoes and melons.

Medical marijuana growing operations can use the plant ready liquid fertilizer in setups that employ micro-fine drip ‘ferti-gation’ or drench-irrigation.

Making liquid fertilizers is a highly sustainable farming practice.

Growers can easily make liquid fertilizer by submerging fresh cut grasses, silaged grasses and food waste into water tanks. From there the nutrient extracts and decomposted solids pass through a series of vessels that give us a plant-ready product with high NPK fertilizer numbers. This is a low labor and inexpensive process to maintain:

  • All nutrients are trapped in enclosed vessels
  • pH conditions are maintained that minimize ammonia and methane loss
  • A combination of anaerobic and aerobic fermentation minimizes odors
  • Grass and food waste have more nutrients and few pathogens vs using manures to make fertilizer
  • By staging liquid extraction processes farmers can create blends from storage vessels containing concentrates of NPK nitrogen, phosphorus and potassium.
  • The biomass residue from fertilizer leaching and extraction is a perfect feed stock for earth worms.
  • The process of making fertilizer liquids, when using the Nutricycler™ or NPK Brewery™ is fast, on average 2-4 days!
  • Because liquid fertilizers can be used as foliar sprays, fertigation or for plant drenching, getting them the plants is effortless.
  • No tillage required when using liquid fertilizers.
  • Green waste management with no runoff and no atmospheric nutrient loss is good for the environment.
  • Processing possible year round and in cold climates as the NPK Fertilizer Brewery™ is primarily an indoor fertilizer facility.

Composting is not!

Organic farmers have difficulty competing with inorganic farmers and showing a profit, because the composting methods are typically not sustainable. That’s because:

  1. Making compost is not the same as making fertilizer. Compost has much lower NPK numbers.
  2. Composting is labor intensive
  3. Composting loses nutrients such as ammonia and methane to the atmosphere
  4. Compost piles require moisture but nutrients are leached to the ground or else runoff
  5. Effective use of composting requires soil tilling, a method that leads to further nutrient degredation and microbial loss.
  6. Compost piles take months to complete a ready-to-use soil conditioner.
  7. Spreading compost is also labor intensive!
