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. So to achieve optimum yields it is important to apply nutrients as close as possible to the rooting zone in frequently and readily available forms.
Yara's crop nutrition programs for onions can help you to achieve excellent crop performance and maximise the yield and quality of onion crops.
Identify and diagnose if your onions are suffering from nutrient deficiencies and learn how to control or correct the deficiency. Choose a nutrient below to learn more about the symptoms of its deficiency in onions and its effect on crop growth and development.
Our collection of tools help you to make better nutrient decisions in making the right fertiliser choice and applying the right amount of nutrients at the right time and in the right place so that the crop yield and quality can be maximised whilst still keeping costs in check, avoiding over-fertilisation and protecting the environment.
