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.

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.
