a 100kg NPK 15: 15: 15 compound fertilizer has a filler make -up weight of
Answer Details
The filler makeup weight of a compound fertilizer refers to the weight of the inert materials added to the fertilizer to bulk it up to a desired weight. It has no nutrient value and does not contribute to the fertility of the soil.
To find the answer to this question, we need to use the ratio of the fertilizer which is 15:15:15, representing the percentages of nitrogen, phosphorus, and potassium. The total percentage of nutrients in the fertilizer is 15+15+15=45%.
Since the weight of the fertilizer is 100kg, the weight of the nutrients in the fertilizer is 45kg. Therefore, the weight of the filler makeup is the difference between the weight of the fertilizer and the weight of the nutrients.
Filler makeup weight = Total weight of the fertilizer - Weight of the nutrients
Filler makeup weight = 100kg - 45kg
Filler makeup weight = 55kg
Therefore, the filler makeup weight of the NPK 15:15:15 compound fertilizer is 55kg.
