About Hydrocache™

Built by Scientists, Backed by Farmers

Hydrocache™ is a carbon enriched polymer soil conditioner, developed by scientists and trusted by farmers, that combines biochar carbon granules with carefully sized super absorbent polymer (SAP) granules to hold water and soluble fertiliser in the root zone where plants need it most. It can absorb up to 250 times its volume in water, then slowly releases moisture and nutrients over time, reducing losses through evaporation and leaching and helping crops cope with irregular watering and load shedding. The biochar delivers long term soil health and structure, while the SAP provides immediate gains in water and fertiliser efficiency, making Hydrocache™ both practical and profitable in real farming conditions. Patents are pending in South Africa and the USA and Hydrocache™ is trademarked in South Africa and registered as a Soil Conditioner with the Department of Agriculture in South Africa, Namibia and Botswana.


Why Hydrocache™ Matters?

Farmers, greenkeepers and growers face the same struggle. Water is expensive, rains are irregular and light sandy soils lose water and fertiliser quickly. The result is stressed plants, uneven growth and higher input costs.

High water loss through evaporation and leaching

Fertiliser washing past the root zone

Crops suffering during load shedding or restricted irrigation



Ideal For A Wide Range Of Growing Environments

Hydrocache™ can be mixed into the root zone during planting, added to planting holes for trees and shrubs, or incorporated into topsoil for turf and landscaping.

Frequently Asked Questions

Yes, Hydrocache™ is designed to be safe for most agricultural, horticultural and turf crops when used at the recommended rates. It sits in the soil profile, holding water and nutrients around the roots rather than acting on the plant directly.

Hydrocache™ has a dual action. The super absorbent polymer component provides immediate water and nutrient retention benefits and gradually breaks down over time, while the biochar carbon delivers long term improvements to soil structure, carbon levels and microbial activity and can remain effective in the soil for decades, with benefits quoted as 99+ years for the organic carbon component.

Yes. Hydrocache™ is intended to work alongside your current fertiliser and irrigation programme. It is mixed into the soil where it absorbs irrigation or rainfall together with dissolved nutrients, then slowly releases them back to the roots, improving the efficiency of the inputs you already use. No special equipment is required, only correct placement in the root zone.

Yes. In sandy soils Hydrocache™ helps to hold water and nutrients that would normally leach away, while in heavier or clay soils it supports better structure, aeration and moisture distribution in the root zone. It can be used across a wide range of soil types, with application rates adjusted to local conditions and cropping goals.
