Organic Fertilizers: Natural Options That Build Soil & Save Money

Organic fertilizers feed soil biology, which feeds plants. No salt buildup. No groundwater contamination. Often free or cheap from waste streams.

Top Choices

• Worm castings (vermicompost): Microbe-rich, balanced NPK, won't burn. DIY with red wigglers + kitchen scraps.
• Rabbit manure: Pelletized, high-N, no compost needed. Best all-around animal manure.
• Composted horse/poultry/goat manure: Excellent but must compost—fresh burns plants, attracts flies.
• Plant-based: Banana peels, leaves, sawdust, crop residues. Compost first.

Vermiculture Bonus

Worms process waste → castings 5× N, 7× P, 11× K vs topsoil. Bin fits under sink. Zero cost after worm purchase.

Safety Protocol

Test soil annually. Match amendments to deficits. Compost all non-pellet manures. No grease/oil in worm bins.

Organic fertility isn't a product—it's a cycle. Close the loop. Grow better.
