Biomass retention
WebHigh biomass retention (2x) decreased plot tree growth as compared to normal bio-mass retention (1x) levels (P < 0.05) after three years. This growth difference was not explained by soil moisture, temperature, or nutrient uptake. While there were strong tree growth differences between study locations, pat- WebTreatments, including woody biomass removal, will be sustainable and will not compromise soil organic matter, the recruitment and retention of coarse woody debris, or wildlife habitat. If needed, use NRCS CPS 384, Woody Residue Treatment. If applicable, use biomass harvesting guidelines (The Forest Guild, 2010) and/or State guidance.

WebMay 7, 2010 · Because of the low specific conversion rates of the one-reactor process, the bottleneck in this combination has been insufficient biomass retention. Much more biomass could be retained if fast-settling, compact granules of a coculture of nitrification and anammox bacteria (a “granular sludge”) were used. WebBecause of the profound impacts that crop residues have on agricultural productivity and soil health, a sustainable utilization of these residues is required. Thus, we determined crop yield and quality response for a range of biomass retention rates in grain cropping systems.
