“Stop Guessing: How Roots Actually Take Up Nutrients (Mass Flow, Interception, Diffusion Explained)”

Описание: n this episode of The Dirt on Growing, host Brandon Rust of FulCrop Sciences breaks down how plants really absorb nutrients – from the moment they leave the bottle to the moment they cross the root membrane. We’ll unpack the three major delivery systems to the root zone (mass flow, diffusion, and root interception) and then zoom in on how nutrients actually enter the plant through passive and active transport.

You’ll learn:

Why poor VPD, cold roots, or waterlogged media can make your plants look “deficient” even when the bottle is perfect

How ATP-powered proton pumps and root respiration drive real nutrient uptake

How carbon, microbes, and chelation (humic/fulvic, organic acids, root exudates) turn your root zone into a nutrient-efficiency machine

Practical tweaks to irrigation, environment, and media that make every drop of fertilizer work harder for you

Whether you’re in living soil, coco, or hydro, this episode will help you stop guessing, stop wasting nutrients, and start engineering your root zone like a pro.
