An international news service reported that a private health insurer in Australia announced it was "back in the black with its first profit in three years."企业利润都用黑色数字记录，所以，“in the black”代表企业处于盈利状态。一家国际新闻机构报道称，澳大利亚一家私人医疗保险公司宣布，三年来他们首次重新赢利。

But yields of organic fruits and other perennial crops nearly equaled the yields from conventional ones. So did the yields of legumes such as soybeans. Legumes produce some of their own nitrogen fertilizer.平均而言，有机农场比传统农场产量低25%。但有机水果和其它多年生作物的产量几乎等同于传统产量。黄豆一类的豆科植物产量也是如此。豆科植物能够自己产生一些所需的氮肥。

However, organic vegetables and cereal crops like maize and wheat had a lot lower yields compared to conventionally grown crops. Ms. Seufert says the soil on organic farms holds water better, and that can reduce the yield difference. 然而，有机蔬菜，以及玉米和小麦一类谷类作物的产量比常规种植作物低很多。Seufert女士表示，有机农场土壤可以更好地保持水分，这可以缩小产量差异。
