The literal meaning can be understood, that is, glyphosate is useless to this kind of corn, so glyphosate can be used when weeding. The advantage is that no-tillage method can be used when planting corn. To put it simply, weeds can be pulled up in a grassy farmland without turning over the ground. Turning over the soil will lead to the loss of organic matter in the soil.
Generally speaking, it brings great convenience to farmers. In addition, it can also accumulate the organic matter content in farmland, which has a certain effect on improving the soil environment.
For example, in China, there are many places where corn is planted in farmland, and the organic matter content is less than 1%. However, in the central part of the United States, where genetically modified corn is planted, the organic matter content has been rising since no-tillage and can reach more than 5% at present.
