NMAN is a software tool developed by OMAFRA to assist farmers in predicting nutrient generation from livestock and determining land base requirements for agronomic use of nutrients; including manure, washwaters and non-agricultural source materials (NASM) such as municipal biosolids.
The latest version of NMAN (v3.2) was released in December 2012. It can be used to generate nutrient management strategies and plans (NMS/P) and NASM Plans; as well as other user summary reports.
Between November 2010 and December 2012 there were two different versions of NMAN in use at the same time. NMAN v2.1 was used to prepare NMS/Ps and other agricultural nutrient management reports. NMAN v3.1 was used to prepare NASM Plans. The current release, v3.2, replaces both v3.1 and v2.1. Now there is one NMAN that is used for both NMS/Ps and NASM Plans.
NMAN is accessible using Microsoft Silverlight, a free plug-in, powered by the .NET framework and compatible with multiple browsers, devices and operating systems. This new framework allows users to work online or offline and allows OMAFRA to deliver more timely software updates.
