Feed the soil and your fertiliser goes further

Every bag of feed you put down is only as good as the soil holding onto it. On light, sandy or tired ground, nutrients wash straight past the roots and out of reach. Humic and fulvic acids change that: they improve the soil's ability to hold nutrients and release them where the grass can use them.

That is the whole job of TerraCharge Liquid. Better nutrient retention, better uptake, and more value out of the feed you have already paid for.

Humic and fulvic - two jobs, one bottle

Humic acids are the larger molecules. They work down in the rootzone, improving soil structure and its capacity to hold onto nutrients rather than letting them leach away.

Fulvic acids are smaller and more mobile. They move readily into the plant, helping the grass take up and use the nutrients that are already there. Put the two together and you get a soil that holds more and a plant that uses more.

Why Mowd?

Concentrated, not watered down

A little goes a long way - one small bottle treats a whole lawn, so you are not paying to ship water around the country.

Straight to work

Diluted and sprayed, it reaches leaf and rootzone the same day rather than waiting on rain to break granules down.

Made by turf pros

Built on 40+ years of sports and domestic turf experience, blended and bottled in the UK.

Frequently asked questions

What does humic acid do for lawns?
It improves your soil's ability to hold onto nutrients instead of letting them wash through - what the turf world calls cation exchange capacity. The practical result is that the feed you apply stays available to the roots for longer, which supports stronger root growth and healthier grass.
How often should I apply liquid humic and fulvic acid?
Every four to eight weeks through the growing season works well, and it is a sensible partner to each seasonal feed. It is not a fertiliser, so it will not burn - but there is no benefit in going heavier than the rate on the pack.
Will it green up my lawn on its own?
Not by itself. The analysis is 0% nitrogen, so colour still comes from your feed. What TerraCharge Liquid does is help your lawn get more out of that feed. Use the two together rather than swapping one for the other.
What is the difference between this and granular TerraCharge?
Same job, different delivery. The granular version is spread dry and works into the rootzone over time; the liquid is diluted and sprayed, goes to work quickly and is easy to apply evenly on smaller lawns. Choose whichever suits your kit and your routine.
