No, they don't, because it's a different type of nutrient system. Yes, organics take time to break down, because the rhizobacillus has to eat organic matter and shit out what the plants can take up. "Slow release" implies chelated synthetic nutrients that leach from pellets which use fillers to slow the release of nutrients so that it's distributed over time. There's an important distinction between "slow/controlled release nutrients" and "organic nutrients." Say organic if it's organic.
Don't get so snippy. Most people don't think of organics as "time released," they think of it as organic. It isn't the same thing.
