Frequently asked questions
TerraCottem universal is the “original” soil conditioner, still to use in most applications such as trees, shrubs, revegetation, annuals, perennials, roof gardens, agriculture, horticulture and potting soils. Hence the name ‘universal’.
TerraCottem turf is specific for sports turf and ornamental lawns, turfed, seeded or sprigged.
TerraCottem works at root level. It is therefore very important that you incorporate the soil conditioner homogeneously into the root zone or that you mix it with the growing medium.
- Trees: mix TerraCottem thoroughly with the soil from the planting hole.
- Lawns & flowerbeds: incorporate TerraCottem into the soil with a tiller, rotovator or cultivator 20 cm deep.
- Flowerpots and hanging baskets: mix TerraCottem thoroughly with the potting soil.
The simple answer? The soil conditioners were developed to remain active for a long time. For at least 8 years. The detailled answer is complex and requires us to break down the soil conditioners into their main groups of components as each group has a different lifespan.
This depends on the type of application:
- For lawns, flower beds and roof gardens: 100 to 120 g per square metre (100 to 120 g/m² = 10 to 12 kg/are)
- For planting trees and shrubs: 1.5 kg per cubic metre of soil from the planting hole (1.5 kg/m³ = 1.5 g/l);
- For baskets & flower pots: 5 kg per cubic metre of substrate (5 kg/m³ = 5 g/l)
We have 2 types of professional packaging:
- “paper” bags and plastic resealable tubs. The bags consist of three layers of kraft paper and a PVC humidity barrier. As a rule of thumb we recommend to consume the bags within 2 years of the “manufacture date” which is stamped on the packaging. It’s is imperative that the bags are stored in a closed and dry place. They should not be stored outdoors.
- The plastic 5 and 10 kg tubs are hermetically closed. Their storage is not affected by air humidity as long as they have not been opened. They store for longer than the bags.
Why do some saturated polymers remain visible on the surface after the initial watering and how long does this last?
A very pertinent, but tricky question to answer. It is very situation and application specific. Longstanding customers report the following savings:
- Inputs: Water savings between 40 and 80% and fertiliser savings betweeen 20 and 50%.
- Maintenance: time, labour and input costs 25 to 80% lower than in untreated soils.
- Replacement costs: a reduction in mortality between 20 and 100%. We can make a detailed cost-benefit analysis for you.
No. The water retention capacity is not necessarily relevant in terms of performance, as high water retention capacity does not necessarily mean more plant available water (PAW).
Not at all. The hydroabsorbant polymers in the TerraCottem mixtures were chosen for, amongst other things, their ability to absorb, retain and ultimately make water available to plant roots. They have absorption tensions which allow plant roots to pick up the water on demand.
