Effect of Tillage Treatments of Hairy Vetch Residues on Soil Inorganic-N Distributions and Corn Growth in a Subtropical Region
Figure 1
Ammonium-N and nitrate-N levels distributed in three soil depths (0–5 cm, 5–10 cm, and >10 cm) at 9, 23, and 65 days after treatment (in absence of corn), shoot and root addition (SRN and SRT), root addition (RN and RT) and without hairy vetch addition in no-tillage (CN) and tillage (CT).
