Abstract/Contents:"Grow-in is the stage in turfgrass ontogeny that requires the highest fertilizer rate, but also a stage implying high risks for nutrient leakage. A total input of up to 50 g N/m2, or 2-4 times the seasonal fertilizer rate for mature turf, is not uncommon during the ten to twelve weeks grow-in period on a sand-based creeping bentgrass green1,2. While newly germinated seedlings require the same balanced diet of macro- and micro-nutrients as mature turf, there is usually a special focus on nitrogen (N) and phosphorus (P) in this period. In 20173, we presented evidence that arGrow Turf, a liquid fertilizer based on amino acids (SweTree Nutrition AB, Ume^Doa, Sweden), could double the establishment rate and reduced N leaching by 40-45 % compared with a liquid mineral fertilizer based on nitrate and ammonium. However, in that trial, no fertilizer was applied before seeding, and the N rates during the 10-wk growin period were only 7.5 or 15 g N/m2. The objective of the present research was to validate the benefits of amino- acid based fertilizers for creeping bentgrass establishment at higher fertilizer rates. This also included an early evaluation of an experimental, not yet commercialized, amino acid based granular fertilizer, here to referred as Amino Granular Concept 1, in comparison with a mineral slow-release fertilizer commonly used for turfgrass grow-in."
