Fig. 2

Full season and stage-wise differences in plant available NH4+-N, NO3−-N, and total-N in soil solution during the wheat growing season (average for two cropping years). Lowercase letters denote differences for NH4+-N, capital letters for NO3−-N, and lowercase italic letters for total-N. Error bars denote ± 1SD. Treatments with the same letters are not different significantly (P < 0.05). Refer to this figure for a description of treatments
