Why the right soil structure determines growth

Soil as the basis of life

Many hobby gardeners and farmers think of soil first as “dirt”. In fact, soil is a complex ecosystem of minerals, organic matter, water, air and microorganisms. Soil structure helps determine how much water is stored and how easily plants can access nutrients.

Soil types and their challenges

• Sandy soil: loose structure, water drains away quickly, nutrients are leached out.
• Loamy soil: a balanced mix of sand, silt and clay; holds water and nutrients well.
• Clay soil: stores a lot of water but can become compacted, making it harder for roots.

This is exactly where RETENTIS® comes in: the granulate stores water and dissolved nutrients in the root zone and releases them gradually. This is particularly noticeable on light, sandy soils, where water otherwise drains away quickly.

Why structure is so important

• Water storage: loose soil absorbs water more easily; heavy soil holds it longer.
• Root zone: the easier the soil is for roots to penetrate, the more water and nutrients reach the plant.
• Soil life: microorganisms and organic matter keep nutrient cycles going.

Practical tips

1. Work RETENTIS® into the soil before planting; do not scatter it on the surface.
2. Choose the dosage according to the application: 10–20 g per litre of soil, 200 g/m² in perennial beds, 100 g/m² for lawns.
3. Water thoroughly after working it in so that the granulate absorbs water.
4. Combine with compost or other organic material; they complement each other well.
