Answer :
Potash you need to buy for 118 hectares as much 2124 pounds.
To calculate the total amount of Potash needed for 118 acres based on a recommendation of 18 lbs K2O per acre, we multiply the recommended rate by the total number of acres.
Total Potash needed = Recommended rate per acre * Total acres
Total Potash needed = 18 lbs K2O/acre * 118 acres
Total Potash needed = 2124 lbs
So, you need to purchase 2124 pounds of Potash to cover 118 acres with a recommended rate of 18 lbs K2O per acre. This calculation ensures that the proper amount of Potash is applied to meet the crop's nutrient requirements and optimize growth.
