The term Auxiliary fertilizer is defined as a substance that is neither a plant food nor a pesticide, but has a positive impact on plant health. Auxiliary Fertilizer is an organic material that, when applied in small quantities, enhances plant growth and development such that the response cannot be attributed to application of traditional plant nutrients.
Auxiliary Fertilizers have been shown to influence several metabolic processes such as respiration, photosynthesis, nucleaic acid synthesis and ion uptake. They are not fertilizers meant to correct a severe nutrient deficiency, but are mixtures of one or more things such as microorganisms, trace elements, enzymes, phytohormones, and seaweed extracts. They may enhance nutrient availability, water-holding capacity, increase antioxidants, enhance metabolism and increase chlorophyll production.
Auxiliary Fertilizers do not act directly against pests. They complement plant protection products (PPP’s) enabling plants to make optimal use of these conventional inputs.
