How many pounds of soluble potash does a 100-pound bag of 10-10-12 fertilizer contain?

To determine how many pounds of soluble potash are in a 100-pound bag of 10-10-12 fertilizer, it's essential to understand the numbers in the fertilizer label. The label indicates the proportion of nitrogen (N), phosphorus (P), and potassium (K), respectively. In this case, the fertilizer is formulated with 10% nitrogen, 10% phosphorus, and 12% potassium.

To find out how many pounds of soluble potash are contained within the bag, you would calculate 12% of the total weight of the fertilizer, which is 100 pounds. This is done by multiplying the total weight by the percentage represented by the potassium:

100 pounds x 0.12 (representing 12%) = 12 pounds.

Thus, there are 12 pounds of soluble potash in this 100-pound bag of fertilizer. This knowledge is crucial for properly managing nutrients in agricultural practices, ensuring that plants receive the appropriate amounts for optimal growth.
