Abstract

Biochar (BC), an aromatic carbon (C) rich compound has been used to sequester C in terrestrial ecosystems. Biochar has also been shown to improve soil fertility and crop productivity when applied to soil. Biochemical properties of soil are sensitive parameters that indicate the change in soil processes that result from soil management practices. Major knowledge gaps exist on the long term effects of biochar addition in cropped field soils. Therefore, a field experiment (3 yrs) was conducted on a Warden silt loam soil to investigate the changes in soil biochemical properties following three years of corn (Zea mays L.) production with applications of biochar (BC), fertilizer (NPK) or dairy manure (DE). The NPK or DE treatments were applied annually, while BC was applied only the first year. Organic carbon (TOC), total organic nitrogen (TON), TOC to TON ratio (CNR), soil microbial biomass carbon (MBC), Metabolic quotient (MQ), potential mineralizable nitrogen (PMN), fluorescein diacetate hydrolysis activity (FDA), acid phophatase activity (ACP), alkaline phosphatase activity (ALP), β-glucosidase activity, urease activity (URA), and soil pH were evaluated at 0-15 and 15-30cm depths after the 3rd year of corn production. A soil quality index equation was also developed with linear scoring functions. NPK or DE with BC application increased soil pH, TOC, MBC, FDA, CN ratio, ALP and URA while decreased MQ and ACP activity. Biochar had little effect on N dynamics in the soil. Application of biochar to both NPK and DE treatments improved the soil quality index as compared to that without biochar.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
