Function of Zinc (Zn) in crop production
Zinc is an important micronutrient used in crop production worldwide as it stimulates enzyme activity in plants. The function of zinc is to help the plant produce chlorophyll. Leaves discolor when the soil is deficient in zinc and plant growth is stunted. Zinc deficiency causes a type of leaf discoloration called chlorosis, which causes the tissue between the veins to turn yellow while the veins remain green. Chlorosis in zinc deficiency usually affects the base of the leaf near the stem.
Zinc deficiency can affect most plants, especially on high pH sandy soil with higher levels of phosphate. All crops in the UK are susceptible to Zinc deficiency and can show various signs of distress as a result. For example, Zinc is commonly used to suppress powdery scab on potatoes where the innoculum is at low levels.
Soil sampling and applying the right nutrients before planting will ensure Zinc is in plentiful supply or do an analysis of the leaf to detect Mn deficiency.
Liebig's Barrel
Liebig's law of the minimum, often simply called Liebig's law or the law of the minimum, is a principle developed in agricultural science by Carl Sprengel (1828) It states that growth is dictated not by total resources available, but by the scarcest resource (limiting factor).
In short, you can have an abundance of all nutrients but if you are missing vital micronutrients your crops will suffer and your yield fall.
Function of Manganese (Mn) in crop production
Manganese is essential in crop production particularly for enzyme systems and for photosynthesis to function properly. The first sign of Mn deficiency is a change of leaf colour. Lack of Mn in the soil seriously impairs crop growth, quality and yield.
Deficiency can occur in most crops, especially those grown on organic, peaty, light soils with a pH level of above 6.0 or mineral soils with a pH above 6.5. Soil sampling and nutrient application before planting will ensure this does not occur or do an analysis of the leaf to detect Mn deficiency.
Function of Sulphur (S) in crop production
Since the clean air act, less Sulphur is naturally falling from our skies in the rainfall. Crops previously could gather natural sulphur from rainfall but this is no longer the case, so Sulphur now has to be put on every crop in the form of fertiliser applied products and slurries. In a plant with sulphur deficiency you will see less mobility and yellowing leaves especially in newer growth. Sulphur is an important nutrient for all plants and crops to grow efficiently and is a key component in development of enzymes and amino acids. Sulphur is involved in the process of photosynthesis and protein production.
