Mass balance vs material balance
WebThe aim of this study was to determine N recovery and irreversible losses (i.e., through NH3-N volatilization) from manure in two different housing systems throughout a year using an N mass balance approach. Dietary, milk, and manure N were monitored together with outside temperatures in six dairy barns during six months, comprising two different seasons. … WebMaterial Balance.

WebThe material balance time is the ratio of current cumulative production and daily flow rate, which could be described as tc = Np / q. Its geometric meaning has been shown in Figure 1.8. Based on this equation, the equivalent relationship between producing with a constant and variable rate could be built.
