What are water-soluble plant fertilizers in general?
Most water-soluble fertilizer in stores today is synthetically manufactured from petroleum. These synthetic fertilizers are not approved for organic gardening. The concentrated chemicals can burn plants instead of helping them (not to mention beneficial critters and earthworms). These synthetic chemicals are generally manufactured in commercial chemical plants from the petroleum-based feedstock.
While synthetic fertilizers do provide giant amounts of NPK, they skimp on all the other important nutrients. Organic options are more likely to provide important trace nutrients, beneficial bacteria, and mycorrhizae. OMRI-listed water-soluble organic fertilizer is a safer alternative for your garden and for the overall environment.
Organic products can be just as quick and effective as synthetic products at providing nutrients to your plants. Natural fertilizers provide plants with the big three nutrients (N-P-K) as well as other less-famous (but still important) nutrients. Organic water-soluble fertilizers are less likely to contribute to the pollution of waterways and much more likely to encourage a healthy soil environment for the long term.
