Abstract

There has been a recent increase in amino acid-based products used for fertilization in turfgrass management. Amino acids are simple organic compounds that contain both a carboxyl group (COOH) and an amino group (NH2). Research has shown when foliarly applied, some of these organic compounds can enter the plant through leaf tissue, making these an interesting source of nitrogen for plant growth. Fertilization with amino acids also has been shown to increase plant performance more than that of equivalent applications of mineral nutrition only.
