Dear Biran

Thanks for kind cooperation
I read the N balance.out file. Here I have two question. First,  which term
is nitrate leaching, and second why N leached (NLCC:1.1 Kg/ha)  is very low
in comparison to measured value( 18.2 kg/ha).I need help to justify it.Can I
send  to you my N balance .out file ? Please tell me how can I send this
file through DSSATserver.I tried many times but unable to send.I if you need
other file , please write me.

Bipin
