| Category | Materials | Typical Claims |
|---|---|---|
| Soil Conditioners | - Composted organic materials
sometimes supplemented with other materials such as limestone or rock phosphate - Ground mineral deposits Mined humates or humic acids - Various materials such as evaporated sea water or sulfates sometimes combined with other materials such as kelp or whey or extracts of these materials |
- Loosen tight soils |
|
Mineral Nutrient Sources (Used Unconventionally) |
- Guaranteed analysis but only smallamount present or recommended |
- Increase yields - Balance nutrition - "Natural" plant feeding - Reduce fertilizer need - Low salt indices - Increase nutrient availability - Improve crop quality - Greater stress resistance - Improve soil condition |
| Wetting Agents | - Nonionic
surfactants - Linear alcohols or ether compounds |
- Loosen tight' soils - Increase water infiltration - Make water wetter - Increase moisture holding capacity - Eliminate wet spots - Release "looked" soil minerals - Improve crop quality and yields |
| Biological Inoculants and Activators |
- Super strains of N fixers - Non-symbiotic N fixers - Many organisms to enhance decomposition - Microbial activity which produces substance near plant which stimulates growth |
- Substitution for fertilizer N or other nutrients - Improve germination - Improve tilth - Better root systems - Increase crop quality and yield |
| Plant Growth Regulators and Stimulants |
- Small amounts
affect physiological plant processes - Fermentation derived |
- Increase yield - Enhance harvesting - Improve quality - Increase nutrient release - Increase rooting and drought resistance |
| Nonconventional Systems |
- "Energize" fields Systems - Magnetic seed treatment |
- Increase yields - Improve germination - Better roots |
