Abstract
Contour diagrams, computed from analyses of soil around bands of aqueous ammonia injected under grass, show the distribution of both NH4-N and nitrifying bacteria.When applied at 155 kg NH3-N/ha, either as 4·7 or 9·3 g N/m of injection slit, using knives spaced either 30 or 60 cm apart, aqueous NH3 was recovered and nitrified more slowly in the bands 60 cm apart. Cumulative yields of grass after 32 weeks were the same (715 ±30 g/m2) from plots injected at either spacing but growth was more even throughout the season from slits 60 cm apart.Keywords
