Calculation of liquid fertilizer formulations
Thread Content
The calculation methods for solid compound fertilizers and water-soluble fertilizers are based on specific ratios, such as 18-18-18 or 30-10-10; the calculation is done by selecting water-soluble fertilizers and using those ratios. I would like to ask the experts: for water-soluble fertilizers in liquid form containing major elements, it is required that the concentrations of nitrogen, phosphorus, and potassium be greater than 500 g/L. For example, in a formula like 300-100-100, the values for nitrogen, phosphorus, and potassium are given in g/L. How can this be converted into the format of solid compound fertilizers? What would the corresponding values be? There’s also 170-170-170; how is this relationship calculated? Waiting online
The conversion between the percentage content of fertilizer nutrients and g/L is based on density, with g/L = percentage content * density
The nutrient levels in the formula are expressed in g/l. 100 g of potassium sulfate provides 52 g of potassium oxide; when the volume is adjusted to 1 liter, the concentration of potassium oxide becomes 52 g/L. The key points are complete dissolution and the selection of additives
