fertilising said crops?

Eh? either he nitrate has gone into teh plantst or it hasn't. If its

Its perfectly possible to grow willows with very little nitrate. Or
ghrow a crop of field beans one yaer and then plant the willow.

Seems like a paticularly stupid idea to me.

Yes, but its YOUR idea not his.
