When you feed the life in the soil, those growing populations of microorganisms begin to accomplish many jobs that now consume great amounts of your time, money, and energy. These are only five examples, derived from a far greater list. It is widely accepted by researchers that many of the benefits we get from soil life have yet to be discovered.
Organic fertilizers contain raw materials meant to stimulate and feed the life in the soil.
Synthetic fertilizer ingredients contain very little that feed the life in the soil. The benefits of feeding the soil cannot be quantified or qualified on any fertilizer label. It s a good idea to take some soil samples from your lawn and send them to a lab for analysis. If any one essential soil nutrient is deficient, you may not get the desired response from your fertilizer. Take several samples with a clean tool from the top 5-6 inches of the yard, remove any undecomposed residues, and mix all the samples together in a clean container.
