10 l
HGA Foliar Fertilizers
Simple inorganic micronutrient fertilizer, mineral micronutrient fertilizer, 5,5 % Zn solution
10 l
Zinc (Zn) complexed by HGA, water-soluble, 5,5 % m/m
Zinc complexed with biodegradable and durable heptagluconic acid
Exhibits a strong systemic effect – enters the plant and takes its effect throughout
Stimulates auxin synthesis, promoting root system development
Increases plant resistance to low temperatures and drought
Supports blooming
Bioactive zinc maintains a low concentration, which prevents the risk of phytotoxicity
Heptagluconic acid (hereinafter referred to as “HGA acid”) is an organic complexing agent in fertilizers containing micronutrients. HGA acid is effective, biodegradable, has good stability over a wide range of pH values, and high solubility in water. The use of HGA has been authorized for many years in Spain, and no harm to the environment or human health has been reported during that time [COMMISSION REGULATION (EU) 2016/1618 of 8 September 2016].
