Because agriculture uses the most water out of any industry, improper irrigation and drainage is a recurring problem. Oversaturation of farmland can wick sodium, calcium, and magnesium from the soil and water to the surface. If left unattended, this process steadily concentrates salt in the root zone, which decreases productivity for crops that are not salt-tolerant. Soil management requires the ability to identify areas with drainage issues to avoid salinity problems
Farmers are also being asked to increase production without harming the environment. To avoid the widespread use of pesticides and herbicides, they need a way to monitor application and mitigate excess chemical residue and runoff. By only spraying the minimum amount required for plants remain strong, ensures the final product remains healthy for human consumption.
