Quaterne Terra (Quaterne Terra, Quaterne Terra Organic)

French expertise in soil health: Quaterna Terra

For professional growers focusing on high-quality yield, soil management is the primary challenge. The organic fertilizer Quaterna Terra from the French manufacturer SARL SOBAK (Zone Artisanale, 12740 Lioujas, France) is designed to restore soil potential while providing balanced plant nutrition. Unlike simple mineral salts, this product acts as a soil improver, essential for sustainable farming.

Field and Orchard Application

The main objective of using Quaterna Terra is to enhance the physical, chemical, and biological properties of the soil. It is effectively used across a wide range of crops, including vegetables, strawberries, apples, cereals, and oilseeds. The practical benefits for the grower include:

• Improved Shelf Life and Transportability: Due to the calcium and magnesium content, the fertilizer reinforces cellular membranes. For fruits like apples and berries, this translates to better post-harvest durability and higher market value.
• Soil Microflora Support: The inclusion of Nitrogen (1–5%), Phosphorus (0.1–1%), and essential microelements creates a thriving environment for beneficial microbes, which is vital for intensive crop production.

The product comes in convenient granular form, ensuring ease of mechanical application. The recommended rate for main application is 100–200 kg/ha, while up to 1 kg/ha is sufficient for targeted feeding. With a hazard classification of 4, it is safe to handle and perfectly suited for eco-conscious agricultural practices.
