Organic vs Chemical Lawn Fertilizer

Why Are Synthetic Fertilizers Bad For a Lawn?

  1. Almost all synthetic lawn care fertilizers are derived from petroleum products.
  2. Synthetic lawn fertilizers neither build the soils, nor feed beneficial microbial activity, in fact they kill beneficial microbial activity and therefore they also kill soils.
  3. Synthetic lawn fertilizers are not sustainable because they only feed the plant and when the chemical fertilizer is used up, the plant will need another application of synthetic fertilizer to stay healthy and green.
  4. Synthetic fertilizers are usually in a fast release form and if a fast release fertilizer is over applied to a lawn it can burn the grass. The reason this can happen to a lawn is because to a plant nitrogen is a scarce resource and up until commercial fertilization most nitrogen came in the form of rain or snow. For millions of years plants adapted to absorb as much nitrogen as fast as possible whenever it rained or snowed. The problem is that plants don’t have a shutoff. Therefore, if fast release nitrogen is available the grass it will continue to absorb the nitrogen even to the point of overdose and death. This is called a nitrogen burn on a lawn.
  5. Synthetic fertilizers can green up a lawn very quickly, but the color fades almost as quickly as it developed. To sustain a green lawn with synthetic fertilizers frequent applications of fertilizer are required. Since synthetic fertilizers kill the soil if the regular applications are stopped the plant will not have any source for nutrients and the health of the lawn will quickly fade. Therefore, synthetic fertilizer applications become very necessary to sustain the health of the lawn. This is one reason that chemical lawn care companies in Boulder and Fort Collins apply 7-8 applications of fertilizer per year.
  6. Synthetic fertilizer applications for lawns, feed from the top of the soil and at short intervals therefore, can promote a shallow and weak root structure.
  7. Over time the continued use of synthetic lawn fertilizers will require more water and more fertilizer to obtain the same deep green color that can be achieved from a few applications of organic grass fertilizers. This is why chemical lawn care companies need 6, 7, or 8 applications per season to maintain a green lawn and Organo-Lawn can provide a deeper and darker green lawn with only 4 or 5 lawn care applications per season.
  8. The more often chemical fertilizers are used on a lawn the worse the soil quality will become. The soil in the Boulder and Fort Collins area already is poor and the more often chemical fertilizers are applied the worse the soil will become.

Lawn Care - Organic vs Chemical


Why Organic Fertilizers Are Better for a Lawn?

  1. Organic lawn fertilizers feed the lawn and trees, but they also feed the microorganisms in the soil. Soils that are teeming with microorganisms are called living soils and these beneficial lawn microorganisms build and sustain nutrient levels in the soil.
  2. Organo-Lawn's 100% organic plant based fertilizers are renewable and sustainable. The plant based fertilizers feed the microbes which build the soil and the soil will feed the lawn and trees. Compare this to synthetic or chemical fertilizers which are derived from petroleum products and cannot be recreated after the oil is all gone.
  3. The nitrogen in organic plant based fertilizers is naturally slow release and therefore cannot burn lawns or trees. This means the organic grass fertilizer will only become available to the plant as nitrogen after it has been broken down by beneficial microbes.
  4. Organic plant based fertilizers stimulate beneficial microbes and beneficial bacteria.
  5. During extremely hot summer days or colder temperatures in the winter the microorganism activity is reduced and therefore, the availability of nitrogen to the lawn and trees is less abundant protecting the plant-life from excessive nitrogen exposure during extreme hot or cold periods.
  6. The symbiotic relationship between microorganisms and organic fertilizers is marvelous. The microorganisms create a living soil which is a naturally controlled release nitrogen source, a preventative for lawn diseases and will not cause excessive growth.
  7. The slower uptake of nutrients develops stronger tissue growth, deeper digging grass roots, and a deeper dark emerald green foliage in the lawn.
  8. Other benefits of organic fertilizers and healthy microorganism activity include the synergistic effects of naturally balancing soil pH; the boosting of potash and iron levels, increasing plant root density, reducing problematic lawn fungus activity, and fostering the decomposition of thatch.
  9. Organic plant based fertilizers add humic matter to the soil and therefore reduces soil compaction. The soil in Colorado is very high in clay and can become compacted easily. Boulder and Fort Collins area lawns that have been with Organo-Lawn for multiple seasons will have less compacted soils.
  10. Organically fertilized soils have proper soil porosity and therefore hold water better and reduce lawn watering needs.
