The Nature and Action of a Growth Fertilizer


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 fertilizer 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 fertilizer 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 fertilizer.


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 fertilizer.


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.
