Biochar is known to ameliorate soil fertility and increase crop yield;however,information regarding its effects on soil chemical and biological properties remains *** experiment was conducted to study the short-term impacts of dif-ferent types of biochar on soil C fractions,enzyme activities,and microbial community structure at depositional and eroded landscape positions at different sampling times[before planting,after planting,and after harvesting of soybean(Glycine max L.)].Three biochar materials,produced from C-optimized gasification of corn(maize,Zea mays L.)stover(CS),pon-derosa pine(Pinus ponderosa Lawson and ***)wood residue(PW),and switchgrass(Panicum virgatum L.)(SG),and dairy manure(DM)and mixture of dairy manure and pinewood biochar(DMP),were applied at a rate of 10 Mg ha^(−1) to depositional and eroded landscape *** showed that the application of DMP and sole application of DM treat-ments significantly increased the labile C fractions at the depositional and eroded *** addition of DM and DMP increased the activities ofβ-glucosidase and urease enzymes,and those are involved in C and nitrogen cycling at depositional and eroded landscape *** were no significant differences between different biochar ***,there was an increase in soil microbial community structure in the DM and DMP treatments at both the landscape *** conclusion,our study revealed that DMP and sole application of DM influenced the soil labile C pool,enzyme activities,and microbial community structure at both the landscape positions for different sampling times.
