Replenish all TerraCottem Universal components that have been consumed by the plants during their growing season by incorporating TerraCottem Complement, the soil conditioner specially formulated as a complement for applications in flower beds and crops that have been previously treated with TerraCottem Universal.
At the end of the growing season in which TerraCottem Universal has been applied for the first time, part of the product has been consumed by the plant and another small part is removed when pulling out plants. The application of TerraCottem Complement in previously TerraCottem Universal-treated soil, brings the level of growth precursors, fertilizers and polymers back to the initial quantities of the TerraCottem Universal formula.
Definition of TerraCottem Complement
Physical soil conditioner, specially formulated as a complement for applications in flower beds and crops previously treated with the “Universal” soil conditioner. It has been designed to replenish the components that have been consumed by the plants during the previous growing season. Due to its application the nutrient and water holding capacity of soils and growing media is kept in optimal conditions. Root development and plant growth are improved, as well as the structure and performance of soils and growing media.
The soil conditioning technology has to be mixed homogeneously into the root zone or growing medium.
Applications
Apply TerraCottem complement when planting, in areas where the “Universal” soil conditioner has been applied the previous growing season.- Crops (agriculture, horticulture, etc.)
- Flower beds
Application frequency
- Once per season, when planting or just before seeding.
Benefits
- Healthier plants & increased yields
- Increased survival rate
- Earlier harvesting
- Increased water retention capacity
- Water savings
- Faster & better plant establishment
- Stronger & deeper root development
- Increased microbiological activity
- Better use of fertilizers
- Higher resistance to drought stress and diseases
