化學耕作還是有機耕作?

在過去的半個世紀里,在耕作中使用化學肥料已經(jīng)非常普遍。許多農(nóng)民喜歡使用化肥,

把化肥作為防治農(nóng)作物病蟲害和增產(chǎn)的重要手段。然而,最近科學家們發(fā)現(xiàn)長期使用這些肥

料會對土地造成損害,甚至更危險的是,會對人們的健康造成危害。

化學肥料都能造成哪些問題呢?首先,它們殺死有害細菌和害蟲的同時也殺死了有益細

菌和益蟲,從而對土地造成損害?;瘜W肥料還會在土壤和地下水中保存很長時間。這將會影

響農(nóng)作物,因此影響到動物和人類,因為化學物質(zhì)會進入到農(nóng)作物里面,并且不能被沖洗掉。

食物中的這些化學物質(zhì)會隨著時間的推移而在人體內(nèi)逐漸堆積。很多化學物質(zhì)能導致癌癥或

其他疾病。另外,使用化學肥料種植的水果、蔬菜和其他食物通常生長過快而缺少足夠的營

養(yǎng)。它們可能看起來很好,但里面通常含更多的水分而不是維生素和礦物質(zhì)。

由于這些發(fā)現(xiàn),一些農(nóng)民和很多消費者開始轉(zhuǎn)向有機耕作。有機耕作就是不使用任何化

學肥料的耕作。他們主要是想保持土壤肥沃且免受病害。健康的土壤能減少病害并促進農(nóng)作

物茁壯生長。因此,有機耕作的農(nóng)民通常更喜歡使用天然的動物糞便作肥料。他們認為這樣

能使土壤中的礦物質(zhì)更豐富因而也會更肥沃。這也能使空氣、土壤、水和農(nóng)作物不受化學物

質(zhì)的污染。

有機耕作的農(nóng)民也使用很多其他的方式保持土壤肥沃。他們經(jīng)常每隔幾年就在一塊土地

里更換一次農(nóng)作物,例如,今年種植玉米或小麥,來年改種豌豆和大豆。像豌豆或大豆這樣

的農(nóng)作物能使土壤重新富含重要的礦物質(zhì),這為種植需要肥沃土壤的農(nóng)作物,如小麥和玉米

等做好了準備。有機耕作的農(nóng)民也使用不同的土壤層種植作物,例如,先種植生長在表層土

壤的花生,然后種植生根于深層土壤的蔬菜。有些有機耕作的農(nóng)民喜歡在農(nóng)作物之間種草來

防止水土流失,然后將草留在地里成為來年農(nóng)作物的天然肥料。這些不同的有機耕作方式有

一個相同的目標:種植好糧食并避免損害環(huán)境和人們的健康。
