A Soil Situation

Chemistry Level 1

A farmer by the riverside has plants that are turning yellow, and they realize that their soil has a nitrogen deficiency. They want a method to add nitrogen to the soil to enable proper plant growth but do not want to use any means that would contribute to runoff and contaminate the river nearby. What is the best solution for the farmer?

$A)$ Add some cattle manure to the soil from the nearby farmhouse $\\$ $B)$ Place lightning rods throughout the farm to attract lightning $\\$ $C)$ Plant a crop of peas before planting the other crops $\\$ $D)$ Add a layer of compost-rich soil on the top layer of the farm $\\$ $E)$ Add a high-nitrogen fertilizer to the soil

$A)$ Would contribute to runoff as rain could easily wash the manure into the river $\\$ $B)$ Lightning rods do not actually attract lightning, therefore there would only be a regular amount of lightning nearby the farm even with the addition of lightning rods $\\$ $C)$ This would works as peas are part of the legume family which are a nitrogen-fixing variety of plants $\\$ $D)$ Would contribute to runoff as rain could easily wash the nutrients from the compost into the river $\\$ $E)$ Would contribute to runoff as rain could easily rinse the fertilizer into the river $\\$

$\boxed{C}$ is the only solution that would not contribute to runoff in the river
