The quality of water and nutrient solution used in controlled environment agriculture (CEA) production systems, such as greenhouses and vertical farms, is one of the most important factors that affect plant health and yield. Growers monitor water and nutrient solution quality by sending samples for analysis to determine the levels of nutrients and salts. They also use sensors to monitor pH and electrical conductivity (EC) regularly to determine necessary adjustments for the nutrient solution. Growers may also analyze the microbiome, the genetic material of all the bacteria, fungi, and viruses that live in their water and nutrient solution, to evaluate levels of harmful pathogens, such as Pythium and Phytophthora species that cause root rot.

This post on poinsettia problems was contributed to by Drs. Chevonne Dayboll and Sarah Jandricic.
When poinsettias get problems, they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.
After reading the previous posts in this series, you’re now aware of WHICH pathogens can be spread through your irrigation water, WHERE they can accumulate, and WHY that’s important. We’re now moving on to posts covering WHAT you can do about it!
This post will walk you through how to sample water sources on your farm, and which tests you can run to determine if your water is helping – or hurting – your crop.
