Aminoacids
Amino acid fertilizers are obtained, with high enantiomeric purity in their L-α-amino biologically active form, by enzymatic protein hydrolysis. Amino acids are readily absorbed, transported, and utilized as a source of nitrogen and carbon for plants. These play multiple roles in N uptake and assimilation, plant signaling, C:N metabolism in the plant, stimulating plant metabolism immediately, and can increase microbial biomass, soil respiration and soil fertility. Although primarily serving as nutrients for the plant, specific amino acids can play additional roles as biostimulants.
