Feather Meal Soil Fertilizer

Slow release 13-0-0

Feather meal slow release nitrogen soil fertilizer is a common by-product of the poultry industry and is allowed under the NOP. Although total nitrogen levels are fairly high (10 to 13%), the nature of the fertilizer is to break down and release nitrogen slowly. Feather meal begins to release its nitrogen within 4-7 days of application. About 75% of the nitrogen is released at a steady rate “slow feed” as plants metabolize the nitrogen for 3 months or more. The slow release nitrogen decreases the chance of “burning” plants, with the remaining nitrogen releasing for up to another 3 months.
