"Amino acids are the basic building blocks of all proteins and thus essential for the growth and development of plants, for the formation of enzymes and storage proteins, for the metabolic processes and reactions of the plant and to make the plants more resistant," reports Friedrich Boecker of agroplanta GmbH & Co. KG. Accordingly, amino acids play an important role in plant growth.

At the same time, a fertilizer with amino acids is not the same as an amino acid fertilizer, he continues. "If growth is inhibited by drought or cold, the production of amino acids by plants is put on the back burner so that many functions cannot be carried out. A deficiency manifests itself in increased susceptibility to disease and inhibited growth." An additional supply is only useful if it is provided in the form of 'free' amino acids. "With free amino acids, the user can react immediately and accurately to the current state of vegetation or acute external stressors."

Amino acid content not reliable
Boecker emphasizes that proteins have to be broken down into their individual components to produce an amino acid fertilizer. It is therefore not enough to just look at the amino acid content of a product. Aserpro, an Agroplantas organic N fertilizer made from animal by-products, contains 17 natural free L-amino acids for immediate absorption and utilization. This promotes stress resilience and metabolism, supports protein and enzyme formation, and increases yield and quality.
Aserpro can be mixed with all common agricultural inputs and can be used in crop production, in greenhouses/protected cultivation, in seed or substrate treatment, as well as in fertigation, the company says. For fruit and vegetables, it is recommended to use as needed, and for potatoes at planting and during cultivation.

Practical trials with potatoes and apples
In a practical trial with Fontane potatoes, the company reports a net tuber weight of 1,747 g per plant compared to 1,216 g in the control, and a lower number of growth cracks with 4.2 compared to 9.7 in the control. In the trial with Kanzi apples, a better calcium content was observed at 46.9 mg/1,000 g after treatment with Aserpro compared to 38.90 mg/1,000 g in the control, as well as a significant improvement in the K:Ca and N:Ca ratios.
