How much is a unit of fertilizer in kilograms?

Answer 1

Typically fertilizer recommendations for field crops are made in lbs of the fertilizer per acre. Example - 200lbs/ac of 12-12-12 (this would supply 20 lbs N, 20 lbs P, and 20 lbs K per acre).

The Analysis (X-X-X) shows us what PERCENTAGE of each nutrient is available by weight. Example; 100lb bag of 20-20-20 spread out over an acre will provide 20lbs Nitrogen, 20% lbs Phosphorus, & 20lbs Potash (PER AREA) of the total weight of the bag, therefore an acre would receive 20lbs of each nutrient.

Respectfully, the above (answer) would yield 24lbs/acre of each. If the analysis were 10-25-50, the amount of ACTUAL AVAILABLE NUTRIENT per bag (in a 100lb bag) would yield 10lbs N, 25lbs P, & 50lbs K. Keep in mind that the pellets are composed of fillers & binders.

Answer 2

One percent (1%) of the nutrient ingredient present in one ton of fertilizer is what a unit of fertilizer is.

Specifically, the unit indicates the percentage weight of each nutrient ingredients. The nutrient ingredient is symbolized with the letter N-P-K for the three macroingredients nitrogen, phosphorus, and potassium. The nutrient amount needed divided by the unit percentage tells how much of the package needs to be used to meet the nutrient needs of the plants and soils in question.

Answer 3

The figure 1.23 is what a unit of fertilizer is in kilograms.

Specifically, a unit of fertilizer identifies the percentage weight of a nutrient ingredient in a bag of fertilizer. The unit is written as a number and tends to stand for the percentage weight of nitrogen, phosphorus or potassium. For example, 15-15-15 represents 15 units each of the three above-mentioned macronutrients.
