Fuel prices, freight charges and avian influenza are driving up prices for organic fertilizer, according to Steve Lundeen with Midwestern BioAg. Lundeen manages the Milledgeville, Illinois location. Supply is tight for chicken litter because of the depopulation of big flocks and it's hard for trucks to go in and out with biosecurity measures, he says. High commodity prices make for an ideal time to start transitioning your farm to organic if that's something you're interested in. He sees organic acres increasing because of the value-add to consumers. He's also seeing interest in 'soil health' products, such as calcium to extract nutrients from the soil, which can be cheaper than adding nutrients.
