The APTUS approach combines soil amendment, plant stimulation and targeted nutrition.
In the field of plant nutrition, it is rare to question the origin and quality of the ingredients used in the composition of fertilisers and bio-stimulants. The bioavailability of nutrients is optimal when the components used are organic or organo-mineral, contain a minimum of ballast salts and no heavy metals. Most nutrient products on the market are mixed and diluted in a large amount of water and chelated using cheap chemicals. These manufacturing methods produce poor quality nutrients with low bioavailability. The plant must expend energy to convert the nutrients before it can exploit their potential. Chelation of nutrients in L-amino acids is the most natural and also the most effective method of achieving rapid and complete uptake by plant tissues. All Aptus nutrition products are chelated in L-amino acids and contain 100% active ingredients.
