Table 1 Setup of the two-factorial incubation experiment. Treatment codes are no-addition control (MP-N-), microplastic only (MP + N-), urea only (MP-N+), and addition of both microplastic and urea (MP+N+)
From: Microplastic fibers affect dynamics and intensity of CO2 and N2O fluxes from soil differently
Incubation procedure | Treatment | |||
