I want to know what will be the dose of 13:13:13 (npk) liquid fertilizer as ml/lit water, if I applied one time/ha. (recommended dose same i.e. 13-13-13).
Fertilizer Dose Calculation
Nutrient amounts are technically figured in pounds. If you're trying to figure out how much fertilizer to apply to a given area, you need to consider the size of the area, the concentration of the fertilizer, and the type of plants. I might add that determining lbs per acre, or even sq ft, is usually more important in agriculture than home gardening. Most people just use fertilizer as recommended on package, sprinkling or pouring around each plant. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/fertilizer-numbers-npk.htm
