英语的化学问题。高手来。悬赏350。急。

if you had a field of corn to grow,but the soil had no nitrogen in it.find 3 ways to add nitrogen to the soil.explain which bacteria was used,and the compounds created.这是题目。意思是你有一片天的玉米。但土地里面没有氮气。要用3个方法添加氮气到土地里。还要说明使用的是哪个细菌。还有产生了哪种复合物。

方法

Adding composted manure to the soil

Planting a green manure crop, such as borage

Planting nitrogen fixing plants like peas or beans

Adding coffee grounds to the soil (be careful as this will also raise the acidity level)

add fertilisers with high NPK ratio.

复合物：ammonia/nitrogen dioxide

细菌：nitrogenase/cyanobacteria

if you had a field of corn to grow,but the soil had no nitrogen in it.find 3 ways to add nitrogen to the soil.explain which bacteria was used,and the compounds created.这是题目。意思是你有一块玉米地，但土地里面缺少氮元素（氮肥），请用3种方法把氮元素添加到土壤里。还要说明使用的是哪个细菌。还有产生了哪种复合物。

解析：这道题旨在考察生物固氮的原理，化学品在生活实际中的应用。

So you'd better translating the theory ,then use two chemical method to explain the phenomenon.

Compost 堆肥

manure 粪便

organic fertilizer 有机肥料

尿素
