The value of grass

The value of grass as a livestock feed is often undervalued.  This calculator uses the costs of alternative standard bought-in feeds to calculate the value of the grass as a feed and also calculates the cost of nitrogen fertiliser to grow the grass as a proportion of the value of the grass.
