From: Co-application of high temperature biochar with 3,4-dimethylpyrazole-phosphate treated ammonium sulphate improves nitrogen use efficiency in maize

Figure 1

The yield of maize aboveground biomass at full maturity. USAS (un-stabilized ammonium sulphate) and SAS (stabilized ammonium sulphate with DMPP). Different upper-case letters indicate a significant difference between variants within the same treatments of the same soil. *Represents a significant difference along biochar treatments of SAS and USAS (pair wised t-test between 1% BC of USAS and 1% BC of SAS and between 2% BC of USAS and 2% BC of SAS). #Represents significant difference of pair wise t-test along different soils of similar treatments (CON of USAS Chernozem with CON of USAS Cambsiol and likewise). NoAS No ammonium sulphate, CON control, 1% BC 1% biochar, 2%BC 2% Biochar.
