Växthusnäringen

Växthusnäringen refers to the nutrient solutions used in greenhouse cultivation. These solutions are carefully formulated to provide plants with all the essential macro and micronutrients required for optimal growth and yield within a controlled environment. Unlike soil-based agriculture, where nutrients are naturally present or added to the soil, greenhouse systems often rely on soilless methods like hydroponics, aeroponics, or substrate culture.

The composition of växthusnäringen is critical. It typically includes nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur as macronutrients. Micronutrients such as iron, manganese, zinc, copper, boron, and molybdenum are also vital, though required in smaller quantities. The precise balance and concentration of these nutrients are adjusted based on the specific crop, its growth stage, and environmental conditions within the greenhouse. pH and electrical conductivity (EC) are key parameters monitored and managed to ensure nutrient availability and uptake.

Växthusnäringen can be delivered in various ways, commonly through recirculating systems where the nutrient solution is reused, or in drain-to-waste systems where the solution is discarded after one use. The development and application of växthusnäringen have significantly contributed to the efficiency and productivity of modern greenhouse farming, enabling year-round production of high-quality crops.
