EC value for fertigation of tomatoes

Jarrod King · May 2, 2017

What EC value would you recommend for continuous drip fertigation over tomatoes growing in very sandy soil?

I don't want to go so high they are burned but I want to explore pretty high level fertilization this way.

That chart says 2-5 for hydroponics but says values for soil will be different. How different?

This https://www.nrcs.usda.gov/Internet/F...2p2_053280.pdf says soil levels of >2.5 lead to decreased yield but I don't know how to predict how the fertigation liquid will change the soil saturated paste EC value.
