Nutrient Deficiency Explanation

Author: Yates  


When our plants are looking unhappy, we immediately suspect they’ve been attacked by a pest or disease. It is, of course, important to rule out such problems but, if leaves are discoloured or distorted and you can’t see an obvious cause, it’s also possible that the problem is caused by a nutrient deficiency.

What is a nutrient deficiency?

Plants must be able to obtain about a dozen nutrients that are found in the soil. The three they require in the largest amounts are nitrogen, phosphorus and potassium. Calcium, magnesium and sulfur are needed in slightly lesser quantities and the so-called ‘trace elements’ – iron, manganese, copper, zinc, boron, molybdenum – in even smaller amounts. But each nutrient is essential and if just one is lacking the plant will grow poorly.

Phosphorus plays an important role for all living organisms and is an essential nutrient element for plants and animals. It has a key position in the combustion processes of the cell, and in the total energy transfer of the plant. It is also a 'building block' of the cell walls, the DNA, and all sorts of proteins and enzymes. For young plants, the presence of phosphate is indispensable; about 3/4 of the phosphorus consumed during a plant’s life cycle is absorbed in the first quarter of its life. The largest concentrations of phosphorus are found in the developing parts o ...

Magnesium is an indispensable element for a.o. plants. In plants, it represents a building block for chlorophyll (leaf green), and therefore, it is essential for photosynthesis. At the same time, magnesium plays an important role in the energy transfer. Together with calcium, it is also a component of tap water, influencing water hardness. Inorganic magnesium fertilisers are produced using the same bases that are used to produce potassium fertilisers. About magnesium in short ...

Iron is a vital element for plant life. Iron has a number of important functions in the overall metabolism of the plant and is essential for the synthesis of chlorophyll. In general, iron is poorly absorbed by the plant. It can only be sufficiently taken up by the roots in certain forms and under proper conditions. Soil seldom contains too little iron, but it is possible that forms of iron that can be absorbed by the plant are lacking. The absorbency of iron is strongly dependent on the pH. Ordinarily, there is sufficient iron present in absorbable form in acidic soils. ...

Nitrogen is one of the important elements a plant needs. It is an important part of proteins, chlorophyll, vitamins, hormones and DNA. Because it is a component of enzymes, nitrogen is involved in all enzyme reactions and plays an active role in the plant’s metabolism. Nitrogen is mainly absorbed by the plant in the form of nitrate and ammonium. It can also be absorbed via small organic molecules. It is important that the balance between nitrate and ammonium is correct in the feeding otherwise the pH in the rhizosphere (environment immediately sur ...

It is necessary for all activities having to do with water transport and the opening and closing of the stomas. Potassium takes care of the strength and the quality of the plant and controls countless other processes such as the carbohydrate system. About potassium in short What is it and what does it do?

Sulphur is one of the molecular building blocks for a number of proteins, hormones and vitamins, such as vitamin B1. It appears in many important plant tissues, such as in seeds and in cellular moisture. In the form of sulphate, sulphur fulfils an important role in the water equilibrium in the plant, as well as in the soil. For hydroponic gardening, all the nutrients a plant needs are given while watering. As a result of this, fertilisers designed for hydro culture contain high concentrations of lime and sulphur. In order to prevent calcium and sulphur from reac ...
