Как да изчислим Fertilizer
Какво е Fertilizer?
Fertilizer calculators determine how much product to apply based on the nitrogen (N), phosphorus (P), and potassium (K) content stated on the bag (the NPK ratio). Over-application wastes money and risks plant burn and waterway pollution through nitrogen run-off. Under-application limits growth.

Ръководство стъпка по стъпка
- 1Amount (g) = (Area m² × N required g/m²) ÷ (N% / 100)
- 2Nitrogen required varies: lawns 25–50 g N/m², vegetables 15–30 g N/m²
- 3Spring applications: use higher N content for growth
- 4Autumn applications: use lower N, higher K for root development
