Field Sampling

For general observations such as plant density, weed density, or estimates of yield, it is important to be sure that the sampling points where you collect your data are representative of the entire field.

For more suggestions, consult the information pages on:

Generally, the data collected in an individual field are averaged to describe that field. If the field has a lot of variability, you may want to make separate sets of measurements in the different sections of the field. While the number of data collection locations per field generally depends on the type of data needed, it is often advisable to select at least 5 to 8 separate locations.

A sheet for recording data at the different sampling points is essential. Here are examples of field sheets which can be used during different stages of crop growth:

Once you have made observations and collected general information about the condition of your field, you can use the following sections to correct crop problems:
