Most school biology students will know the importance of nitrogen (N), phosphorus (P), and potassium (K) for healthy plant growth. However, a more in-depth study reveals that these are just three of many elements playing an essential role in overall plant welfare. Whilst these constitute the main requirement, relatively large quantities of calcium, magnesium, and sulphur are equally necessary. Although plants only need minute traces of micronutrients, these are no less crucial to ensure growing crops thrive.

The seven essential micronutrients for plant growth are:

– Boron (B) – essential for cell wall development and sugar metabolism
– Chlorine (Cl) – important for photosynthesis and water balance
– Copper (Cu) – crucial for enzyme activity and chlorophyll production
– Iron (Fe) – vital for photosynthesis, respiration, and nitrogen fixation
– Manganese (Mn) – necessary for enzyme activity and plant defence
– Molybdenum (Mo) – essential for nitrogen fixation and plant growth
– Zinc (Zn) – important for plant growth regulation and protein synthesis

Even the nutrients in well-fertilised soil can become severely depleted by the end of the growing season. At the same time, some ground may display various mineral deficiencies even before cultivation. In the past, a farmer would have dug in a mix of farmyard manure and vegetable compost and hoped for the best. Whilst this is a long-standing traditional approach, it fails to produce the high yields necessary today. Instead, modern intensive farming relies on precisely formulated mixtures of primary, secondary, and essential micronutrients.

A fertiliser with an appropriate NPK ratio is a fundamental requirement for all plants. However, it can be dangerous to overlook the need for traces of boron, chlorides, copper, manganese, molybdenum, iron, and zinc. For example, copper plays a crucial role in enzyme and chlorophyll activity and promotes seed formation. Iron acts as an activator for photosynthesis, respiration, and nitrogen fixation and is required for chlorophyll production. Factors such as excessive damp, cold, high pH, and heavy rainfall can quickly deplete the small traces of these and other natural micronutrients in the soil.

How to Know Which Elements Need to be Supplemented

Common deficiency symptoms include:

– Yellowing leaves (nitrogen) – conduct a soil analysis to confirm nitrogen deficiency
– Stunted growth (phosphorus) – soil analysis can reveal phosphorus levels and other contributing factors
– Distorted leaves (copper) – accurate soil analysis is crucial to determine copper and other micronutrient concentrations

To determine which elements need supplementation, conduct a soil analysis with Kynoch Fertilizer’s expert testing services. Kynoch Fertilizer offers:

 One need only look at the high incidence of scurvy, rickets, beriberi and pellagra in the world’s poorest countries to spot the connection between dietary deficiencies and these heart-rending manifestations of human malnutrition. Similarly, a field of wilting and discoloured maize clearly indicates that something essential is missing from the soil. Studies have shown conclusively that numerous elements are crucial for plant nutrition. Consequently, shortfalls can lead to growth anomalies, increased vulnerability to disease, pests and drought, and low yields.

Extreme weather conditions, erosion and pH changes can leave soil lacking nutrients. Animal manure and vegetable compost are rich sources of nutrients and can help overcome such deficiencies in the growing area. However, their composition is random, inconsistent and unknown. These natural solutions can be helpful. But, their overall benefits are no match for those of the precisely formulated granular and liquid commercial fertilizers designed to optimise plant nutrition.

In South Africa, where agricultural productivity is crucial for food security and economic growth, understanding plant nutrition is vital. The country’s diverse soil types, climate, and crop varieties require tailored fertiliser solutions to optimise yields.

Fulfilling the Complex Nutritional Requirements of Plants

Although maize, cabbages and potatoes might appear to be relatively simple lifeforms, their physiology is complex. They all depend on access to air, water and selected minerals in their immediate environment. Atmospheric carbon dioxide is plentiful, and irrigation systems can compensate for water shortages during periods of limited rainfall. However, fertilisers remain the only effective way to ensure the required balance of the many essential elements in the soil. Furthermore, a plant’s needs vary at different stages in its lifecycle. For example, phosphorus is crucial to plant nutrition to promote the rapid root growth essential for establishing seedlings. Later it is necessary to aid flowering while also helping to withstand harsh weather and environmental stress.

While phosphorus is the main ingredient of suitable starter fertiliser, additional elements are essential to meet the seedlings’ immediate needs. Naturally, they require nitrogen and potassium. However, magnesium and sulphur and traces of the micronutrients zinc, copper, boron and molybdenum are also necessary at this stage. Chelation can help to ensure that zinc and copper are readily available for plant nutrition.

In South Africa, maize, sugarcane, and soya beans are among the most widely cultivated crops. Each has unique nutritional requirements, making it essential to choose the right fertiliser blend. For example, maize requires adequate nitrogen, phosphorus, and potassium, whilst sugarcane benefits from added micronutrients like zinc and copper.

Offering Crops a Healthy and Balanced Diet

Other mixtures with different elements in various concentrations may be necessary as the growing crop’s needs vary. Thus the best option for farmers is to follow a fertiliser application programme that best suits a given crop. When planting in previously uncultivated or well-used ground, it might pay to conduct a preliminary soil analysis. The results will indicate which elements may most need replenishing to create the ideal balance. Like humans, crops also require a balanced diet to remain healthy.

Like animals, plants require many factors to ensure they grow strong and remain healthy. Animal physiology involves extracting the chemicals for building tissues and generating the energy to achieve this by consuming other animals and plants. By contrast, a plant’s nutritional requirements must be drawn from the soil and the atmosphere. Nature provides the sunlight, carbon dioxide and much of the water required for photosynthesis, and soil is the source of other essential plant nutrients. However, it is an unreliable source, often requiring a growth fertiliser to provide any missing or deficient contents.

Primary Macronutrients Needed by Plants

Plant nutrients fall into three groups depending on the quantities required. Their greatest need is for a group of substances classified as primary macronutrients comprising nitrogen, phosphorus and potassium. However, the need for each element varies between species and at different stages in the growth cycle. Consequently, it is essential to ensure the correct concentrations and relative proportions of these macronutrients when attempting to correct imbalances or deficiencies in the growing environment. Manufacturers take these factors into account when preparing growth fertiliser products.

Nitrogen plays an essential role in protein synthesis and energy production by photosynthesis. Without it, growth is slowed, and plants become discoloured and lose their leaves. Phosphorus is vital for root formation and some aspects of general development, especially during the flowering stage. Potassium regulates water uptake and transport, strengthens cellular tissues, boosts photosynthesis and is necessary for nitrate absorption. If potassium levels in the soil are inadequate, this can reduce resistance to drought, frost and fungal infections. Consequently, it is crucial to include appropriate amounts of these three elements when compiling a growth fertiliser.

Secondary Macronutrients and Micronutrients

By contrast, plants require only moderate amounts of the three secondary macronutrients – the elements calcium, magnesium and sulphur. The first of these has multiple roles ranging from cell wall formation and root formation to mineral retention by the soil, neutralisation of toxins and seed formation. Without magnesium, plants could not produce chlorophyll, and the element is also necessary to activate numerous enzyme reactions. Sulphur is also an all-rounder, having roles in chlorophyll formation, photosynthesis, nitrogen metabolisation and protein synthesis. All three are commonly included in growth fertiliser.

The list of micronutrients required in trace quantities is somewhat longer. It features boron, chlorine, copper, iron, manganese, molybdenum and zinc. Suffice it to say that each element is necessary for some aspect of a plant’s health and welfare. In many cases, generic products can be highly effective. However, Kynoch favours soil-testing to compile bespoke mixtures based on its results for maximum crop yields.
