Ecothrive Soil Food Re-Gen 1kg is an organic powdered soil amendment specifically formulated to restore and revitalise depleted living soil between crop cycles. Combining medium and long-release organic and mineral inputs, Re-Gen replenishes nutrients, supports soil biology and prepares previously used growing media for productive reuse.

Living soil is designed to be reused rather than discarded after every crop. Plants inevitably remove nutrients and minerals from the soil as they develop, so these reserves need to be replenished before the next planting if the soil is to remain productive.

Soil Food Re-Gen is designed specifically for this between-crop stage. Rather than replacing established living soil, it helps put back what the previous crop has removed while preserving the physical structure and biological ecosystem already present.

The formulation is built around olivine, a naturally occurring magnesium iron silicate that steadily releases magnesium and silicon. This is combined with bone meal, Ecothrive Charge mealworm frass and micronised rock phosphate to rebuild soil fertility and support biological activity.

Re-Gen has a typical analysis of 3.5% nitrogen, 5.5% phosphorus pentoxide and 3.5% potassium oxide, alongside 10% calcium, 1% magnesium and 4% sulphur.

Restore living soil between crops

One of the key advantages of living soil cultivation is the ability to reuse the growing medium from one crop to the next.

Mature living soil already contains established physical structure and a biologically active ecosystem. Discarding it after every harvest means losing much of what has developed during the previous growing cycle.

The challenge is that each crop removes nutrients from the soil. Nitrogen, phosphorus, potassium, calcium, magnesium and other elements are incorporated into plant tissue and eventually leave the system at harvest.

Re-Gen is formulated to restore this depleted fertility so that the soil can be prepared for another crop without starting again with completely new growing media.

Balanced nutrition for soil regeneration

Ecothrive Soil Food Re-Gen has a typical analysis designed around the requirements of depleted living soil:

  • Nitrogen (N): 3.5%
  • Phosphorus pentoxide (P₂O₅): 5.5%, equivalent to approximately 2.5% elemental phosphorus
  • Potassium oxide (K₂O): 3.5%, equivalent to approximately 3% elemental potassium
  • Calcium: 10%
  • Magnesium: 1%
  • Sulphur: 4%

This is not intended to function like a conventional fast-acting liquid fertiliser. Re-Gen is designed to restore nutrient reserves within the soil and provide a foundation of medium and long-release nutrition for the next crop.

Olivine for long-term magnesium & silicon

The standout ingredient in Soil Food Re-Gen is olivine, a naturally occurring magnesium iron silicate selected by Ecothrive for its long-term behaviour within living soil.

Rather than producing a rapid increase in soluble nutrients, olivine provides a slow and consistent release of magnesium and silicon.

Magnesium for chlorophyll production

Magnesium is an essential plant nutrient and a central component of chlorophyll. Replenishing magnesium reserves helps prepare reused soil to support healthy photosynthetic growth during the following crop.

Silicon for stronger plant tissue

Silicon contributes to plant structural integrity and can help plants develop greater resilience to environmental and biological stresses.

The gradual mineral release provided by olivine is particularly well suited to living soil, where the objective is to maintain balanced fertility over an extended period.

What's in Ecothrive Soil Food Re-Gen?

Re-Gen combines several complementary organic and mineral ingredients selected to restore depleted living soil.

Olivine

A magnesium iron silicate that provides a slow and consistent source of magnesium and silicon for long-term soil fertility.

Bone meal

A slow-release organic source of nitrogen and phosphorus that helps replace nutrients removed during the previous crop.

Mealworm frass - Ecothrive Charge

Ecothrive's mealworm frass contributes organic nutrition while helping revitalise microbial populations within biologically active soil.

Micronised rock phosphate

Provides a mineral phosphorus reserve to help replenish soil fertility and maintain phosphorus availability through subsequent crop cycles.

Replenish fertility while retaining your soil ecosystem

Living soil functions as a biological ecosystem rather than simply acting as an inert medium for holding roots.

Microorganisms contribute to decomposition, nutrient cycling and the conversion of organic materials into forms that can become available to plants.

Replacing the entire soil after every harvest also replaces much of the ecosystem that has already become established.

Re-Gen supports a different approach: retain the living soil and replenish what the crop has removed. Mealworm frass contributes to biological activity, while its organic and mineral nutrient sources rebuild fertility for continued cultivation.

How to use Ecothrive Soil Food Re-Gen

Soil Food Re-Gen should be applied after harvest and before the next crop is planted.

For indoor pots and living soil beds, use 2-4g per litre of soil. For larger pots and beds, calculate the required amount using the volume of soil in approximately the top 20-25cm.

Ecothrive recommends using 2g/L where plants showed minimal fading towards the end of the previous cycle. Increase to 4g/L where most of the large leaves had yellowed before harvest.

For pots up to approximately 25L, the soil can be emptied from the container and thoroughly remixed with the required quantity of Re-Gen.

For larger containers and living soil beds, blend Re-Gen into the upper soil profile. Ecothrive's low-till guidance is based on hand blending it through approximately the top 20-25cm of soil.

Water thoroughly after application and always adjust the rate according to the condition of the previous crop and the soil being regenerated.

Using Soil Food Re-Gen outdoors

Re-Gen can also be used to restore depleted field and garden soil.

For depleted outdoor soil, Ecothrive recommends 400-600g per m².

Fork the amendment into approximately the top 20-25cm of soil and water thoroughly after application.

This is different from the lighter surface top-dressing method used with Soil Food Grow and Bloom. Re-Gen is intended to rebuild fertility throughout the active upper soil profile before another crop is established.

Part of the complete Ecothrive Soil Food system

Soil Food Re-Gen forms one part of Ecothrive's three-product organic powdered nutrient system for living soil.

Soil Food Grow

Used during vegetative growth to replenish nutrition required for vigorous roots, stems and foliage.

Soil Food Bloom

Used as plants move into flowering and fruiting, with nutrition targeted towards the increased phosphorus and potassium demands of the generative stage.

Soil Food Re-Gen

Used after harvest to restore depleted soil before the next crop begins.

The Soil Food products are designed to work sequentially according to crop stage and soil condition rather than all being applied at the same time.

Preparing regenerated soil for the next crop

Re-Gen provides a foundation of longer-lasting nutrition intended to carry regenerated soil into the early stages of the next crop.

As the new crop develops and begins consuming more nutrients, Soil Food Grow can then be used during vegetative growth when additional nutrition becomes necessary.

This follows Ecothrive's wider living soil approach: replenish nutrients according to crop demand and soil condition rather than feeding plants continuously with soluble fertiliser.

Container size, crop duration, plant demand, light intensity and the number of previous soil cycles can all affect the rate at which nutrient reserves are depleted.

How much soil will a 1kg bag regenerate?

At Ecothrive's indoor application rate of 2-4g per litre of soil, a 1kg bag provides enough Re-Gen for a substantial volume of growing media.

At 2g/L, 1kg is sufficient for approximately 500 litres of soil.

At 4g/L, 1kg is sufficient for approximately 250 litres of soil.

For outdoor depleted soil at 400-600g per m², a 1kg bag covers approximately 1.7-2.5m², depending on the application rate selected.

A practical approach to reusing growing media

Soil Food Re-Gen is built around the principle that productive living soil should be maintained and reused rather than automatically discarded.

Reusing established living soil retains its existing physical structure and biological ecosystem while reducing the quantity of new growing media required between crops.

Re-Gen replenishes nutrients and minerals removed by cultivation, helping growers maintain productive soil over repeated growing cycles.

This makes it particularly useful for living soil pots and beds where replacing the complete growing medium after every crop would be both wasteful and impractical.
