Onions and garlic have a relatively low nutrient uptake efficiency, due to their shallow root system characterised by thick roots with very few and short hairs. To achieve optimum yields it is important to apply nutrients as close as possible to the rooting zone in frequently and readily available forms.
Identify and diagnose nutrient deficiencies in your onions and learn how to control or correct the deficiency. Start by selecting a nutrient below.
Yara's solid fertiliser and foliar programmes for onion are based around YaraLiva calcium nitrate fertilisers, YaraMila solid NPKS fertilisers and the YaraVita foliar micronutrients.
