Definition from
IFIC Foundation:
A methodology of crop production in which the farmer avoids mechanical cultivation (i.e., only one pass over the field). The plant residue remaining on the field’s surface helps to control weeds and reduce soil erosion, but it also provides sites for insects to shelter and reproduce, leading to a need for increased insect control.
Example sentences:
No-till farming, as its name indicates, does away with the mechanical churning of the soil between crops. Rather than being plowed under, agricultural wastes are left on top of the soil, where they decompose more slowly. (World Resources Institute)
The scientists found that certain activities, such as switching to no-till farming, may also increase crop yields while helping the environment. (U.S. Department of Agriculture's ARS)
Conventional tillage controls weed growth by plowing and cultivating, but no-till farming selectively uses herbicides to kill weeds and the remains of the previous crop. No-till farming is one of several primitive farming methods revived as conservation measures in the 20th century. (answers.com)

免耕直播法是指在未经任何翻耕犁耙的农田上，经过一定的技术处理，直接进行农作物播种的栽培技术。

记者近日专程采访了阿根廷直播者协会农业工程师霍金·拉瓦萨。据拉瓦萨介绍，按照传统的耕作方法，人们在播种之前必须先翻耕和平整土地，然后再把种子放入垄里。那么，采用免耕直播法，土地不翻耕，地表又盖着一层秸秆杂草，如何播种种子呢？经过改装的轻型播种机就能胜任此项工作。这种播种机带着小犁头，小犁头把秸秆层拨开，深度恰好接触到泥土，然后再把种子播撒到表层土中。由于表层土长期被秸秆杂草覆盖，一般都很湿润，加上微生物丰富，土质也比较松软，种子播撒后会比较快地发芽，也很容易地把根扎下去。种子发芽后，土层上的秸秆杂草恰恰成了护呵小苗的保护层。

免耕直播稻是指在收获上一季作物后未经任何矗拼犁耙的稻田，先使用灭生性除草剂灭除杂草和落粒谷幼苗、催枯稻桩，灌深水沤田，待水层自然落于或捧干水层施基肥后，将已催芽露白的水稻种子直接播种到大田生长的水稻。
