California Liquid Fertilizer has been spiking its fertilizer with ammonium sulfate for the last several years, affecting the organic status of many farms, including organic behemoth Earthbound Farms.
Organic food in theory means that nothing other than pure, natural ingredients go into the food.
But if they're fertilizing it with anything other than pure cow excrement, fish meal, biochar and bat guano, it's probably got what most people call "chemicals" -- industrially refined ingredients.
Keep paying $4 a tomato, suckers. This society is dishonest and since it doesn't take into account context, will gleefully declare any poop-covered tomato an organic one.
