Nitrogen balance software applied in commercial cattle herds "Nitrofinc".
Abstract
A research study of soil, plant and animal factors was conducted in
intensive rational grazing, for which a Software was designed that performs the
Nitrogen balance and a temperate condition method was applied but with
important variations for the indices in relation to the tropical situation. Be
detected that the nitrogen balance and few element inputs to the system are
negative and presents a deficit exceeding 30 kg / ha / year. The program in practice
It will be used by consultants, extension agents, professors, producers, and all
those related to the activity and having access to computers. He
program allows to determine the nitrogen balance of livestock farms in the
Tropic conditions. Pentium l (586) or
higher. RAM 32 Megabytes. Speed 66 MHz. Free space required
on the hard disk 2 Mbytes. The results are output by printer and screen. He
most appropriate software for your run is under Operating System Windows 98, NT
and higher with Microsoft Access installed.
