Weeds -  What Are They Telling Us?

Weeds are a nuisance in our fields and the reason why we own a sprayer or hoe, if you have vegetable, tobacco or organic fields.  But have you ever stopped to look at which weeds you have or thought about why they grow where they do. Weeds do have a purpose, so what are the weeds in our fields trying to tell us? 

Weeds are good indicators of soil fertility. The roots of weeds are actually nature’s way of attempting to correct whatever soil problem exists.  Weed roots help to bring the lacking nutrient to the surface or aid in breaking up compacted soil.  Let’s take a look at a few common weeds and what they are telling us.

There are several contributors to corn yield. Other than general field fertility, 5 other important factors are:

1. Weather   2. Nitrogen   3. Hybrid   4. Previous Crop   5. Population

There is not much we can do about the number one influence on corn yield, the Weather, but the other four factors are things that we can influence through our management of the corn crop.
