sármeðferð

Sermeðferð is an Icelandic term that translates to "seed treatment" in English. It refers to the process of applying protective or beneficial substances to seeds before they are sown. This practice is employed in agriculture and horticulture to enhance seed germination, protect seedlings from pests and diseases, and improve overall crop establishment and yield.

The primary goals of seed treatment include improving the viability and vigor of seeds, preventing or reducing the incidence of soil-borne and seed-borne pathogens, and deterring insects that can damage seeds or young plants. Treatments can be applied as coatings, dusts, or liquid suspensions that adhere to the seed surface.

Common types of seed treatments involve fungicides to control fungal diseases, insecticides to protect against insect pests, and sometimes growth stimulants or beneficial microorganisms like rhizobia to promote nitrogen fixation. The specific treatment chosen depends on the crop, the prevalent soil conditions, and the target pests or diseases.

Seed treatment is a cost-effective method for crop protection as it targets problems early in the plant's life cycle. It can reduce the need for broad-spectrum pesticide applications later in the growing season, contributing to more sustainable agricultural practices. The application process is typically carried out by specialized seed treatment facilities or sometimes by farmers themselves using appropriate equipment.
