Phytamin®
Our variety of Phytamin® brand liquid products provide varied ratios of NPK nutrients to meet the demands of your crop.
In addition, Phytamin® liquids contain varied amounts of soluble and insoluble nitrogen resulting in both immediately available nitrogen and longer-term availability. All Phytamin® liquids contain very low carbon to nitrogen ratios that result in very high Plant Available Nitrogen (PAN). These products are derived from various nitrogen containing sources of raw materials including fish soluble and plant extracts. Whatever your needs are, we have a liquid product that will deliver results.
Phyta-QC™
Phyta-QC™ products are designed to improve the general quality of crops by providing additional nutrients that the crop may be lacking.
Phyta-Cal QC and Phyta Set QC improve the plant's ability to take up other nutrients and improve plant photosynthesis.

Phyta-Molasses QC has a high sugar and soluble carbon content. Sugar and soluble carbon have been shown to increase microbial activity and soil respiration.
Phyta-Boost™
Our Lawn & Garden products are all-purpose, organic fertilizers.
These products can be used on trees, turf/lawns, vegetables, container plants, shrubs and ornamental vines. The Lawn & Garden Natural Fertilizers are made of the same ingredients we use in our agricultural organic products which have been used successfully by organic growers for over 30 years.
Phyta-Boost™ Plant FoodLabelSDSCDFA OIM Certificate
California Organic Fertilizers (COFI) dry products are protein based (no manures* added as fillers). We find that using animal and plant protein without manure fillers increases the Plant Available Nitrogen and is better for the Soil Food Web. We formulate our products to have the ideal carbon to nitrogen ratio so that the fertilizer is in a form that can be mineralized easily without creating a nitrogen deficit (sink) because of high carbon levels. Click here for more on COFI’s Carbon to Nitrogen (C:N) Ratios.
COFI products are pelletized and go through standard application equipment. Our expertise keeps our products from being dusty or falling apart during application. It also keeps the pellets from being so hard they won’t decompose and become available to the crop. Our pellets are sized to provide uniform distribution on planting beds. As part of COFI’s quality control program each lot number is to make sure it meets or exceeds the label N-P-K guarantee. 
*Manure has a high salt index that may be damaging to plants: additionally, manure may cause a build-up of certain nutrients and minerals and these excess components leach out of the soil and enter waterways. Copper is a common additive in poultry feeds and poultry manure retains this copper which can build up in the soil to a toxic degree, burning plant roots. Manure can raise the acidity of soil over time while also depleting calcium, an essential mineral.
