Polyter Gr*

Polyter GR is a high-performance hydro-retentive fertilizer created to support planting success in increasingly hot, dry and challenging environments. Acting like a water and nutrient reservoir at the root zone, Polyter GR helps plants access what they need, when they need it.

Recognised by the Solar Impulse Foundation as an efficient solution for better water and soil management, Polyter GR is designed for professionals and landowners looking to improve planting results while reducing irrigation needs.

Whether you are planting forest trees, vines, fruit trees, hedges or crops in difficult soil, Polyter GR helps create better conditions for root establishment, growth and long-term resilience.

Key Benefits

Designed to Improve Planting Success

Polyter GR generally delivers 95% success for forest plantations, helping young trees survive and establish even in challenging conditions.

Save 2/3 to 3/4 of Irrigation Water

By improving water retention around the roots, Polyter GR can help reduce irrigation needs by around two-thirds to three-quarters, depending on soil, crop, climate and application conditions.

Faster Plant Development

Polyter GR supports stronger root systems and more vigorous growth. In field use, trees treated with Polyter GR may show faster development, often appearing more mature than untreated trees of the same age. At 5 years old, they are often mistaken for 7-year-old trees.

Better Productivity for Trees, Vines and Orchards

Polyter GR can support healthier, more productive plants by improving access to water and nutrients. This can contribute to better fruit colour, flavour, resistance and overall crop quality.

Useful for Extreme and Degraded Soils

Polyter GR is suitable for demanding planting environments, including:

• Saline soils
• Sandy soils
• Very calcareous soils
• Dry and water-draining soils
• Areas affected by pollution or heavy metals
• Post-mining restoration areas
• Reforestation and land regeneration projects

How Polyter GR Works

Polyter GR is placed near the root system during planting. It acts as a hydro-retentive nutrient reserve, helping retain water and nutrients close to the plant. This gives roots improved access to moisture during dry periods and helps reduce water loss in soils where irrigation normally drains away too quickly.

The result: stronger establishment, better resilience and more efficient use of irrigation water.

Recommended Uses

Polyter GR is ideal for:

• Forestry plantations
• Reforestation projects
• Tree planting
• Vines and vineyards
• Fruit orchards
• Hedges and shrubs
• Landscape restoration
• Soil regeneration
• Agricultural and agroforestry projects
• Planting in dry, sandy, saline or degraded soils

Technical Note

Polyter GR is placed near the root system during planting. It retains water and nutrients close to the roots, helping plants access what they need during critical growth periods and in dry conditions.
