It is based on an average. It is what it is but it was 5 kg/cu. m. The question I am asking relates to the fact that this had to be taken into consideration in the matrix that determined the average cow generates 89 kg of nitrogen. For whatever reason, whether it be through surveys and testing etc, we are now saying it is 2.4 kg/cu. m but yet we have a band up to 106. What matrix was used to achieve the bands? Maths and science were my two weak points going to school and I am finding it hard to get my head around the science.
