Juurilannoitus

Juurilannoitus, also known as root fertilization or basal fertilization, is a horticultural technique where fertilizer is applied directly to the root zone of a plant. This method aims to provide nutrients efficiently to the plant's absorption sites, maximizing uptake and minimizing waste.

The application can be done in various ways depending on the plant and the type of fertilizer. For potted plants, granular fertilizers are often mixed into the potting soil before planting or applied as a top dressing around the base of the plant. In field cultivation, fertilizers can be incorporated into the soil before planting or injected directly into the root zone using specialized equipment. Liquid fertilizers can also be applied through irrigation systems, a process known as fertigation, where nutrients are dissolved in the water and delivered to the roots.

Juurilannoitus is particularly beneficial for plants with specific nutrient requirements or those growing in nutrient-poor soils. It can promote stronger root development, faster growth, and improved overall plant health. By targeting the root zone, the fertilizer is less likely to be washed away by rain or leach into groundwater, making it a more environmentally friendly approach compared to broadcast fertilization. However, improper application, such as placing too much fertilizer too close to the roots, can lead to root burn and damage. Careful consideration of the plant's needs, soil type, and fertilizer type is crucial for successful juurilannoitus.
