Effect of Biochar-Containing Compost on Cucumber Quality and Antibiotic Resistance Genes Abundance in Soil–Cucumber System

The distribution of antibiotic resistance genes (ARGs) derived from compost in soil–plant systems is a serious issue. One possible remedy the application biochar-containing compost. In this study, cucumber quality and abundance ARGs soil–cucumber under different treatments, namely, traditional pig manure corn straw (PC); manure, straw, large particle size biochar (5–10 mm) (PCLB); small (<2 (PCSB); were investigated. results showed that, PCSB, yield, vitamin C soluble protein content cucumbers highest, while absolute intI2 was reduced soil. amount available potassium soil contributed most to changes yield quality. total highest PC, followed by PCLB, CK (control treatment without fertilization) treatments. Compared PCLB PCSB applications decreased sul1 tetG 42–57% 38–80%, respectively, cucumbers. summary, more beneficial increasing nutrient content; improving C, reducing risk input transport system.
