General: This data set is part of a study including three on-going plot-level fertilization sites. The first (LTE-MP-LPA) is in the low marsh at Law's Point along the Rowley River. The second (LTE-MP-LPP) is in the high marsh at Law's Point along the Rowley River. The third (LTE-MP-ORT) is in a brackish water marsh on an upstream tributary of the Parker River. Biomass sampling is slightly different at each site, and is accomplished non-destructively at the LTE-MP-LPA and LTE-MP-ORT sites, and destructively at theLTE-MP-LPP site. Biomass sampling at LTE-MP-ORT was discontinued after August 2008. Sampling Description: Each experimental site has triplicate 1-m2 plots that are fertilized with N (7.5 mol N/m2/y), P (3.75 mol P/m2/y ), both N and P, or neither N nor P (controls). Fertlization occurs during the growing season only. At LTE-MP-ORT, there are two randomly placed 32cmx32cm subplots are placed per plot for sampling each month. The diameter of the culm at the base of the plant and the number of leaves on each Typha plant within each sub-plot is recorded each month. Starting in 2004, only the C and P plots were censused. Data processing: Plant measurements are entered into an EXCEL database, then transformed to biomass using allometric equations (after Daoust, R.J. and D.L. Childers. 1998. Aquatic Botany 62:115-133.).
