Question

If a crop requires 1.5kg phosphorus per hectare, how many kg of manure will be required per hectare if 1kg manure contains 0.32kg of phosphorus

Options

A) 2.47kg

B) 4.69kg

C) 7.35kg

D) 12.3kg

The correct answer is B.

Explanation:

Manure is an excellent fertilizer containing nitrogen, phosphorus, potassium and other nutrients. It also adds organic matter to the soil which may improve soil structure, aeration, soil moisture-holding capacity, and water infiltration.

If 1kg manure = 0.32kg of phosphorus
xkg manure = 1.5kg of phosphorus
(Cross multiply)

x=1.5
0.32
