Plant Doctor Quantum H is a liquid humic acid soil conditioner made from Leonardite ore. It delivers short-chain humic and fulvic acids to tired or nutrient-starved soil, where they help to release locked-up nutrients and feed the soil's microbes.

Why you'll love it

  • It works on nutrient lock-up. Humic and fulvic acids improve nutrient availability, so plants can draw on nutrients that are already in the soil.
  • It feeds soil biology. The humic acids feed soil microbes and lift microbial activity.
  • It improves structure and moisture. Quantum H improves soil structure, and in hydrophobic or compacted soils it helps moisture to infiltrate.
  • It helps rebuild worn-out soil. Plant Doctor recommends it for soils low in organic carbon and for soils affected by residues of herbicides, pesticides or heavy metals.

How to use it

Mix well and dilute at least 1 part in 20 with water. For home lawns and gardens the rate is 1ml per sqm, which is 100ml per 100 sqm, applied fortnightly or as required. For spot treatment, use 35ml in 10L of water. It can go on as a soil drench or through sprinkler and drip irrigation, and it mixes with most fertilisers. Keep it separate from iron-based products.

What's in it

A liquid potassium humate concentrate from Leonardite ore, with short-chain humic and fulvic acids, organic carbon and naturally occurring trace minerals. It conditions soil and is not itself a nutrient source.

Sizes

  • 1L. For garden beds, pots and a small lawn.
  • 4L. For larger lawns and gardens, or a regular soil program.
  • 10L. The bulk size for acreage, orchards and crops.
