The ABC of deficiency symptoms – how to reliably recognize plant nutrition deficits

Every plant has an individual requirement for the supply of nutrients such as potassium, magnesium or sulphur. If cereals, potatoes or sugar beet are not sufficiently supplied with these nutrients then there will be a reduction in yield and in many cases, impaired quality of the harvested crop. Often, such shortages of the different nutrients can be identified through visual symptoms which develop on the crops.

Our experts from K+S KALI GmbH are available to support agriculturists in the identification of nutrient deficiencies. The “Deficiency Symptom ABC” on our website (www.kali-gmbh.com/deficiency_symptoms) provides valuable information on how to recognize, correct and prevent nutrition deficits in various crops. The site has been optimized for mobile use via Smartphone or tablet, and can therefore be accessed directly on site, in the field.

An important factor in the identification of nutrient deficiencies is whether predominantly older or younger leaves of a plant are affected. Some nutrients, such as potassium or magnesium, are highly mobile within a plant. If need be, they are quickly transported to younger parts of a plant, resulting in deficiency symptoms mainly on older leaves. An undersupply of sulphur, manganese or boron, however, will initially show on young leaves. Within the plant, these nutrients are relatively immobile. Newly developed plant growth in particular becomes lacking of sufficient quantities of these nutrients, and plants will therefore show light coloured spots or speckles on leaves (chlorosis) or dieback of plant tissue (necrosis).
