In some cases plants are composited into crop and non dominant plant component. Crops are further separated into seed and stover. Plants are dried at 60 C for a minimum of 48 hours and dry weights recorded along with the date of harvest, field replicate, treatment, sampling station and species code. Leaf production in sites with trees is estimated with two 0.8 x 1.2 m litter traps placed on the forest floor of each site. Details for the ANPP estimates for all treatments are provided below.
Plant tissue is dried and the total biomass of the plot is recorded.
Seed biomass is recorded and moisture sub samples are taken using a Burrows Digital Moisture Computer 700. Seed and stover tissue sub samples are collected, combined by tissue type over stations, and archived for further analysis. Calculate the mean total, seed and stover biomass per plot on a dry weight basis. Botanical separations are performed by species by station, dried, and the dry biomass for each species at each station is obtained. Calculate the mean total LC biomass per plot on a dry weight basis.
