He also plants and harvests on neighbouring farms, which have been reallocated to black owners, and gets half the crop.
耕作可以清除杂草和上一季的农作物残茬，并且有助于将原来的农作物残茬分解成化肥，但它也会增加因风蚀、水蚀造成水土流失的风险。
Tilling can remove weeds and the waste from last season's crops and help break down old plant material into fertilizer. But it can also increase the risk of soil erosion by rain or wind.
在越来越依赖玉米为其提供燃油供应的同时，美国也正对许多可能破坏农作物的风险变得敏感，(这些风险)范围从干旱到(农作物)灾害到暴雨。
As America grows more reliant on corn for its fuel supply, it is becoming vulnerable to the many hazards that can damage crops, ranging from droughts to plagues to storms.
是否能依靠更加先进的生物燃料(比如利用非食物农作物或者利用农作物的纤维素部分、甚至利用柳枝稷或者海藻这些非食物作物来制造生物燃料)来解决上述这些问题还是个未知数。
Those problems might or might not be solved by more advanced biofuels, such as those made from the non-food or cellulosic parts of crop plants or even non-food crops such as switchgrass or algae.
繁殖时一直延续的行为，因为昆虫和疾病总是在进化，气候也在不断的变化，所以我们尝试繁殖出大量的农作物，比如抗干和耐热的农作物。
Breeding is an ongoing activity because pests and diseases are always evolving and the climate is changing. We're always trying to make more productive, drought-tolerant and heat-resistant crops.
据刊登在科学在线的最新研究，农作物所含的碳水化合物中蕴涵着能源，但以农作物为原料生产生物酒精并不是利用它们的最好方法。
Turning the food crop into ethanol would not be the best use of the energy embedded in the kernels' carbohydrates, according to a new study in Science.
俄罗斯的农作物实验基地是专门的农作物基地，农作物都被种在地理，跟活的样本一样。
The crops in the Russian experimental station are almost exclusively crops that have to be conserved them in the field, as living specimens.
此外，值得注意的是，最近的农作物研究不仅关注籽种增长，也关注整株作物的长大。
It is also notable that the latest research into plants is focused not on redistributing growth towards seeds but on making the whole plant bigger.
农作物对磷具有依赖性，由于磷一般均分布在土壤的表层，因而使农作物的根扎得浅。
With crops that rely on phosphorus, he's breeding shallow roots, since phosphorus is typically found in topsoil.
考虑到农作物的价格可能会涨高，这促使人们砍伐原始森林以种粮食作物；另外大量肥料的使用导致了气候变化以及海洋死亡区的形成。
And the potential for a crop price bonanza drives the cutting down of rainforests and heavy fertilizer application causing climate change and oceanic dead zones respectively.
而且这场大干旱对农作物造成很大影响，基本没什么收成，然而农作物却是我最大的收入来源。
And then the long drought affected the crops from which I get most of my income.
但是使用来自农作物实验的数据要冒夸大问题的风险，因为此项实验中的农作物通常是得到良好肥料的——这不同于大多数非洲普通的玉米作物。
Using data from crop trials risks exaggerating the problem, because the plants in such trials are usually well fertilised-unlike most normal maize planted in Africa.
但是使用来自农作物实验的数据要冒夸大问题的风险，因为此项实验中的农作物通常是得到良好肥料的——这不同于大多数非洲普通的玉米作物。
