Answer 1

Explanation:

• Soil fertility is a key factor in determining agricultural potential. All plants take up nutrients from the soil as they grow; these nutrients are removed with any plant that is harvested. Crop rotation or fertilizers are required to prevent even the best soils being depleted by farming.
• Maize farming experiment, Nicaragua. Scientists will use the results to teach local farmers how best to cultivate and fertilize their land. In the absence of any constraints such as availability of water, judicious use of fertilizers can raise yields by 30 percent, but over-use can do more harm than good.
