The mere existence of this job highlights the crucial importance of fertilizer for a nation soon to have a billion mouths to feed. في الولايات المتحدة الأمريكية, we may not need a cabinet-level Department of Fertilization. Yet wed be wise to pay a lot more attention to the strategic significance of fertilizers in our agricultural and energy policies.

Heres a little backgroundwere currently in the midst of a corn boom. In a new report, the Department of Agriculture says that American farmers have planted almost 93 million acres of corn this year, فوق 19 في المئة عن العام الماضي. Since the Second World War, we havent grown more corn in a single year.

The corn boom is fueled by the ethanol boom. The rising cost of energy and mounting concerns about climate change have motivated everyone from venture capitalists to ordinary consumers to think about alternative sources of production.

Thats good news, because we need to develop sources of energy far removed from the oil fields of an unstable Middle East.

Every new opportunity tends to present new challenges, ومع ذلك, and the drive to adopt renewable fuels is no different. One of the most significant new challenges involving the corn and ethanol booms has to do with fertilizer: Were going to need more fertilizer to meet our needs.

The situation is this: Corn needs nitrogen to grow. In normal years, farmers in the Midwest corn belt get what they need from fertilizer and crop rotation.

Soybeans pull nitrogen from the air and deposit it in the soil. When corn plants follow soybeans in a particular field, it requires as much as one-third less nitrogen fertilizer as it would otherwise. كنتيجة ل, many farmers rotate fields back and forth between corn and soybeans. It keeps the soil healthy and saves money.

With corn acres hitting new highs, ومع ذلك, a lot more fields will see corn follow corn. هذا العام, فمثلا, soybean plantings are down more than 11 million acres with about 10.5 million of those acres now planted in corn.

Thats okay, when fertilizer is abundant. Yet the current demand for corn is extraordinarily large. As the biofuel energy sector continues to diversify production with grasses in addition to corn, the demand for accessible and affordable fertilizer will only increase.

Other ingredients also must find their way into a healthy cornfield, such as phosphate (usually from Florida) and potash (typically from Canada). Getting these products to farmers will become increasingly important as we expect farmers to meet our energy needs. Improving our delivery infrastructure systemshighway, rail and riveris also essential.

The bottom line is that the United States doesnt just need a strategic energy plan. As unglamorous as it sounds, we also need a strategic fertilizer plan. حقيقة, the fertilizer plan must be integrated fully into our strategic energy policy plans. We cant have one without the other.

Creating a Secretary of Fertilization or a federal fertilization czar is probably not the way to go. Yet we must bring together all stakeholders, in both the public and private sector, to look at this situation.

A long-term solution will guarantee that American farmers have enough production capacity to meet our countrys demand for fertilizerand thus for food, feed and alternative energy. We have to examine short-range challenges as well: If next winter is a cold one, the price of natural gas will go up, placing additional pressure on fertilizer companies.

The corn and ethanol booms are not flukes. Were going to grow a lot more corn and produce a lot more ethanol in the coming years. We must adjust to this new reality.
