Obtaining plant growth biostimulants by hydrolysis of animal raw materials

Abstract This paper describes the process of obtaining and using complex biostimulants for plant growth, based on enzyme-mediated and acid-mediated hydrolysates of animal raw materials. Animal blood at slaughter was enzymatically hydrolyzed with a substance that contains up to 35% of free amino acids. The effect of biostimulants on development of agricultural crops and forest plants grown from seed after long dormancy was studied. The changes in enzymatic activity of the system were assessed. The prominent positive effect of the biostimulants on the rate of seed germination and formation of green biomass was established.
