What Is Nutrient Balance

The nutrient balance is defined as the difference between the nutrient inputs entering a farming system (mainly livestock manure and fertilisers) and the nutrient outputs leaving the system (the uptake of nutrients for crop and pasture production).

What is a nutritional balance?

A balanced diet is one that fulfills all of a person’s nutritional needs. Humans need a certain amount of calories and nutrients to stay healthy. A balanced diet provides all the nutrients a person requires, without going over the recommended daily calorie intake.

How do you calculate nutrient balance?

Ntot = total N content of the soil of the upper 20 cm, M = mineralization rate (2.5 or 3.0 percent). K leaching was calculated in a similar way with the percentages of Table 13 multiplied by the sum of exchangeable K (in kilograms per hectare) and mineral and organic fertilizer K.
