KBS050:Tracegas fluxes in forests and old fields under enhanced nitrogen regimes

10 m2 plots in the old field and forest ecosystems were fertilized with 2 rates of nitrogen. N2O, CO2 and CH4 measurements were made with a static chamber method

KBS050-001 Log of Fertilizer Applications on the N-deposition Study

Yearly summary of the fertilizer applications for the N-Deposition Study listing the amounts and number of applications that were made to supply the amount of N.

KBS050-002 Detailed Fertilization Log

List each N application that was made to the N-deposition study. The yearly amount is split into 3 equal applications that is applied over the spring summer and fall months.

The treatments are:

  • 1F (all except CF3): 1gN/m2 applied to 10×10m plot, equal to 217g Urea divided into three applications of 72.5g (spring, summer, fall) each mixed with 4L water
  • 1F-CF3: 1gN/m2 applied to 2×3m plot, equal to 13g Urea divided into three applications of 4.3g each mixed with 2L water
  • 3F: 3gN/m2 applied to 2×2m plot, equal to 26.1g Urea divided into three applications of 8.7g each mixed with 2L water
  • 10F (in DF only): 10gN/m2 applied to 2×2m plot equal to 87g Urea divided into three applications of 29g each mixed with 2L water
