Organic

 

 
 
Organic fertilizer also differs from chemical fertilizer in the way they feed your plants and build up your soil. Soils the contain a lot of of organic material will remain loose and airy and hold more moisture and nutrients. This helps to foster growth of soil organisms and promote healthier plant root development. By using only chemical fertilizer, the soil gradually loses its organic matter and microbiotic activity. As organic material is used up by your plants, the soil structure deteriorates, becoming compact, lifeless and less able to hold water and nutrients.

Organic fertilizer is generally made up of mostly water insoluble organic materials that break down and release their nutrients slowly. Organic fertilizers can be more expensive than chemical fertilizers, but they offer many more benefits and you can even make your own with backyard composting. Organic fertilizers tends to last longer as well, since they are mostly water insoluble, they tend to remain where they are applied and help hold soil moisture in and break down hard soils.
