plantenæring

Plantenæring, also known as plant nutrition, refers to the essential elements that plants need to grow and thrive. These nutrients are absorbed from the soil, water, and air. They are broadly categorized into macronutrients, which are required in larger quantities, and micronutrients, needed in smaller amounts.

The primary macronutrients are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is crucial for leaf growth and chlorophyll production. Phosphorus is vital for root development, flowering, and fruiting. Potassium plays a role in overall plant health, disease resistance, and water regulation. Other important macronutrients include calcium (Ca), magnesium (Mg), and sulfur (S).

Micronutrients, also known as trace elements, include iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), and chlorine (Cl). Although required in smaller amounts, they are equally essential for various plant metabolic processes. For example, iron is necessary for chlorophyll synthesis, and zinc is involved in enzyme activity.

Nutrient deficiencies can manifest in various symptoms, such as yellowing leaves, stunted growth, or poor flowering. These deficiencies can occur when the soil lacks sufficient nutrients or when the plant is unable to absorb them due to factors like improper soil pH or waterlogged conditions. Plantenæring can be supplied through organic matter, fertilizers, or soil amendments to ensure plants receive the necessary elements for optimal health and productivity.
