The basics for precision nutrient application is to determine farm’s nutrient balances (at the farm gate, field and stable level). The balances are usually calculated for nitrogen (N), phosphorus (P) and potassium (K). The ideal situation is that the value of the field balance is close to zero, which means that the nutrient uptake of plants and the supply by fertilization are in ideal balance.
