Powerful liquid fertilizer and biostimulant, obtained from proteins of marine origin (salmon), enzymatically hydrolyzed under controlled conditions with high technology. This advanced process allows obtaining a stable product, rich in free amino acids of low molecular weight peptides, favoring absorption via leaves and roots, which allows plants to build their own proteins and tissues quickly, and with great energy savings, especially in environments with nutritional, thermal, water, light or saline stress.
