| Abstract/Contents: | "Recently, there has been an 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 that when foliarly applied, some of these organic compounds can enter the plant through leaf tissue, making them an interesting source of nitrogen for plant growth. Furthermore, fertilization with amino acids has been shown to increase plant performance more than that of equivalent applications of mineral nutrition only. However, not all amino acids are able to enter the plant in this way, and plant catabolism of amino acids is not entirely understood. Preliminary research indicated that when foliarly applied together in combination, the branched-chain amino acids (BCAA) leucine, isoleucine and valine can lead to increases of shoot production in creeping bentgrass putting greens. The objective of this research was to evaluate the branched-chain amino acids leucine, isoleucine and valine as a possible nitrogen source for creeping bentgrass (Agrostis stolonifera L.) under field conditions, over two years. At the end of the trial in both years (84 days post treatment initiation), plants that received applications of leucine, isoleucine, and valine in a 4:1:1 ratio exhibited on average a 48%, 15%, and 6% increase in shoot density, respectively, compared to the untreated control, positive control (urea only), and a commercially available amino acid product that is known to increase shoot density. This concept illustrates the benefits that can occur when fertilizing with organic nitrogen sources such as amino acids, when used correctly." |
