Frequently Asked Questions
Are inorganic fertilizers artificial?
No: Inorganic fertilizers are made from raw materials found in nature (atmospheric nitrogen, deposits of phosphate and potash, etc). These essential nutrients are processed to make them more soluble and readily available to plants, both of which allow for more precise management and timely release of available nutrients to the plant.
Inorganic vs. organic fertilizers: a useful debate?
No: Attempting to separate organic and inorganic nutrients is difficult and of limited value because, in nature, they constantly shift from one form to the other. Plants cannot distinguish between nutrients supplied from organic or inorganic sources. All nutrients to be absorbed by plants have to be available in their inorganic form, irrespective of their source.
Are organic fertilizers safer?
No: As stated in the Codex Alimentarius guidelines on organic farming, “even permitted substances [of organic or inorganic source] may be subject to misuse and may alter the ecosystem of the soil or farm”. Use of excessive amounts of organic sources of plant nutrients is environmentally problematic. Nutrient losses through leaching in humid climates, or by volatilization are unavoidable and may lead to either high nitrate concentrations in soils and water or gaseous losses to the atmosphere. From a human health standpoint, contrary to inorganic fertilizers, some uncomposted or improperly composted organic sources can carry human pathogens.
Do organic fertilizers produce healthier, more nutritious food?
No: Experiments show that the contents of protein, vitamin C and health-benefiting plant compounds such as lycopene and isoflavones in organically grown plants are comparable to levels found in conventionally cultivated crops. Reductions can occur if crops do not have adequate levels of essential nutrients, regardless of the nutrient source.
Are inorganic fertilizers needed?
Yes: Inorganic fertilizers are needed to meet the food needs of a growing population since organic sources are not sufficient. Used together in an integrated plant nutrition approach, they can provide the food and fiber needed by all.
