Summary:
This article is about a person named Jonathan Lynch, who is a plant nutrition professor, who with his colleagues does some experiments for “the second Green Revolution.” The meaning of “the second Green Revolution” is that they research which kind of beans or crops can tolerate the low condition soil growing very well. So, why do the scientists need to develop this research? Because in Arica, there are a lot of farmerd who don’t know how to fertilize crops, and the fertilizer is very expensive in Africa. So, the farmers in those areas need some special seeds, which cost less money and just need simple ways to care for. And crops must have phosphorus to grow luxuriantly, but this substance is just maintained in the surface of soil; most plants cannot absorb it very easily. According the root system, most seed plant’s roots grow deeply under the soil. Therefore, the professor Lynch spent 25 years to explore which kind of beans can grow in the low fertility soil. Through his effort, Lynch and his partners produce some shallow root plants, which meet all of their requirements. However, this research leads to some doubters. Many people believe the soil would be eroded very fast. But the scientists disagree about this belief. Lynch explained that the shallow root plants were good for soil; they could maintain phosphorus move firmly than deep-root plants. Unfortunately, shallow-root plants are harmed by drought. As a result, the researchers are trying to mix the deep-root plants and shallow-root plants together. Furthermore, Lynch also does some research about corn and maize. That is because, in general, most corn cannot absorb nitrogen extremely; as a result, most nitrogen changes into nitrogen oxides. And the nitrogen oxide is a harmful substance, which can lead to global warming. If we can move up the efficiency, that will let the corn absorb more nitrogen. Our countries can save a lot of money. So our scientists are utilizing the root system to find a good way to solve this serious problem. Lynch is searching for some kinds of maize, whose roots can catch nitrogen very fast. So far, he found that some the roots with aerenchyma might suit this researching. Our scientists still try their best to do them.

After reading, I believe our humans are so great that they can find all the research results. Africa is an area which has more problems with it. There, many countries, people cannot subsist their life easily; the resources, the civilization and the rules, many things need us, the other countries, to help them. I know the most serious problem in Africa is food. Many countries don’t have a lot of farmers; they don’t even know how to fertilize! Many people there don’t have education, they don’t know how to write or how to explain their feelings. So the crop failure happened there many times and a lot of people died because of this. In order to solve this problem, the scientists from all the countries come together and try to think out efficient ideas. Lynch’s research is one of these studies. In my opinion, his study not only suits Africa’s situation, but also meets the other countries’ requirements. If this result can be used by a manufacturer, I think this will be the most successful research in 2010. As for another study, finding the efficient roots that can absorb nitrogen speedily, I will pay more attention to it; because if he and his partners succeed, our earth would be better than before. In addition, if we can also produce this kind of plants or crops, the global warming would be relieved,and we might not be afraid of catastrophe which is led by bad climates, and governments can have more money and energy to deal with other problems. In conclusion, this research might be a good news for humans.
