chapter 13 Flashcards
1
Q
what is immobilization
A
the uptake of N fertilizers into the body of bacteria, nitrogen becomes available again only after the organism dies and decomposes
2
Q
how to reduce immobilization
A
can be reduced by subsurface banding N fertilizer
3
Q
other reasons banding is better than broadcasting
A
banding reduces ammonia volatilization
4
Q
why is banding more effective than broadcasting?
A
more cost efficient, reduces ammonia volatilization, more effective than broadcasting
5
Q
why apply in spring rather than fall
A
better efficiency, reduced N-immobilization, reduced leaching and nitrification losses
