Crops can only be called organic if they are grown on land that has not been treated with synthetic products for three years.

只有在三年内没有使用合成产品的土地上种植的作物才能被称为有机作物。

Well, you are right on that point. This is the reason that I don't buy leather and I try to buy synthetic products.

好吧，在这点上你是对的。这也是我为什么不买皮草而是尽量买人造制品的原因。
