    ..5 g CO2-eq m-2 day-1). Although GHG emissions during spring thaw were small compared to those in the growing season, they should not be ignored. ..
  2. Pokharel P, Kwak J, Ok Y, Chang S. Pine sawdust biochar reduces GHG emission by decreasing microbial and enzyme activities in forest and grassland soils in a laboratory experiment. Sci Total Environ. 2018;625:1247-1256 pubmed publisher
    ..These biochars should be tested in long-term field trials to confirm their potential for mitigating CO2 and N2O fluxes in real ecosystems with a relevant time frame. ..
  3. Chang S, Robison D. Genotypic effects of fertilization on seedling sweetgum biomass allocation, N uptake, and N use efficiency. ScientificWorldJournal. 2001;1 Suppl 2:407-14 pubmed
    ..A better understanding of genotype by fertility interactions is important in selecting genotypes for specific site conditions and for optimizing nutrient use in forestry production. ..
  4. Baah Acheamfour M, Carlyle C, Lim S, Bork E, Chang S. Forest and grassland cover types reduce net greenhouse gas emissions from agricultural soils. Sci Total Environ. 2016;571:1115-27 pubmed publisher
    ..Opportunities exist for reducing soil greenhouse gas emissions and mitigating climate change by promoting the establishment of perennial vegetation in the agricultural landscape. ..
  5. Yang H, Lou K, Rajapaksha A, Ok Y, Anyia A, Chang S. Adsorption of ammonium in aqueous solutions by pine sawdust and wheat straw biochars. Environ Sci Pollut Res Int. 2018;25:25638-25647 pubmed publisher
  6. Dugdug A, Chang S, Ok Y, Rajapaksha A, Anyia A. Phosphorus sorption capacity of biochars varies with biochar type and salinity level. Environ Sci Pollut Res Int. 2018;25:25799-25812 pubmed publisher
    ..We conclude that the P sorption capacity of the studied biochars is dependent on the concentration of the soluble element in the biochar, which is dependent on the biochar type, as well as the salinity level in the aqueous solution. ..
