Nutrient Information Nitrogen (N) Nitrogen is the macro nutrient that is required in the largest amount by plants, its availability is therefore decisive to crop growth, yield and quality. Nitrogen is utilised for: • The formation of amino acids. • The production of nucleic acids. • The formation of chlorophyll. Nitrogen generally enters the plant through the root system from the soil/medium in which plants are being grown. However, due to one or a combination of the conditions listed below its uptake may be interrupted or sub-optimal. • • • • • • • • Waterlogging. Cold, wet soils. Drought. Compacted soils. Soil pH. High rainfall. Organic matter levels. Under developed root system. Limitations imposed on nitrogen uptake ultimately lead to loss of yield and quality, which in extreme cases will be seen visually in the field by reduced growth rates and the yellowing of older leaves. The foliar application of an available source of nitrogen to plants will help them overcome conditions where nitrogen uptake by the root system is sub-optimal for healthy growth. This will therefore reduce any potential loss of yield and quality, helping plants to reach their optimal yield.
