Ammonia Nitrogen Losses from Simulated Plowing of Native Sods¹

ABSTRACT

The objective of this research was to measure NH₃ gas evolved from soils that have recently been broken from the native sod condition. Methodology for measuring NH₃ losses under simulated natural environments is presented. Two moisture levels, field capacity, and wilting point were studied. It was concluded that NH₃ volatilization was not a significant loss mechanism in the first 160 days after cultivation began.
