Primary productivity is used to describe the rate at which plants and other photosynthetic organisms produce organic compounds or organic matter or biomass in an ecosystem. • Gross productivity = the entire photosynthetic production of organic matter during photosynthesis in an ecosystem. • Net productivity = the organic materials ...
WebRoot turnover, in units of yr-1, is the ratio of Annual Belowground Production to Maximum Belowground Standing Crop. This approach is a modification of the model initially proposed by Dahlman and Kucera (1965). Approximately one-third of the primary literature sources reported mean rather than maximum root biomass; however, these sources did ... WebOct 27, 2015 · Primary production showed a clear seasonal trend with the highest production during summer and occasional peaks in spring and autumn (Fig. 1A). Taking the median of all monthly values, a boxplot shows the seasonality with highest values in summer and a large variability during the spring bloom in March (Fig. 2A). The biomass of …
