Essential Plant Nutrient: What Do Plants Need

Essential Plant Nutrient: What Do Plants Need

Plants require a variety of nutrients in order to grow and thrive. The three main nutrients that plants need are nitrogen (N), phosphorus (P), and potassium (K), also known as NPK. In addition to these major elements, plants also require smaller amounts of calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, and molybdenum, which are known as trace elements.

Nitrogen (N): Nitrogen is an essential element for plant growth and is found in all plant cells, proteins, hormones, and chlorophyll. Some plants, like legumes, can fix atmospheric nitrogen in their roots. Otherwise, nitrogen is commonly obtained from fertilizers like ammonium sulfate, ammonium nitrate, and urea. Nitrogen is easily leached out of soil by heavy rain, so it's important to apply it in small amounts frequently or in organic forms like composted manure to reduce leaching.

Phosphorus (P): Phosphorus is important for energy transfer in plants, as well as stimulating root and plant growth. Most Australian soils, including the North Coast, lack sufficient phosphorus for sustained crop and pasture production. Superphosphate, made from rock phosphate and sulfuric acid, is the most common source of phosphorus. Manures, especially those from grain-fed animals, also contain phosphorus and can be used as a rich source.

Potassium (K): Potassium enhances plant vigor and disease resistance, aids in starch, sugar, and oil movement within plants, and improves fruit quality. Many sandy soils on the North Coast have low potassium levels. Intensive grazing and horticultural crops can deplete potassium levels in the soil. Muriate of potash and sulfate of potash are commonly used as potassium sources.

Calcium (Ca): Calcium is essential for root health, new root and root hair growth, and leaf development. Acid soils on the North Coast are typically low in calcium. Lime, gypsum, dolomite, and superphosphate are all sources of calcium. Lime is the most cost-effective option for the North Coast, while dolomite is useful for magnesium and calcium deficiencies. Superphosphate is suitable when both calcium and phosphorus are needed.

Magnesium (Mg): Magnesium is a key component of chlorophyll, the pigment responsible for the green color in plants, and is essential for photosynthesis. Sandy acid soils in high rainfall areas, especially those used for intensive horticulture or dairying, are prone to magnesium deficiencies. Heavy applications of potassium fertilizers can also cause magnesium deficiencies. Dolomite, magnesite, or epsom salts can be applied to overcome magnesium deficiency.

Sulfur (S): Sulfur is involved in energy-producing processes in plants and contributes to flavor and odor compounds. Soils high in organic matter usually have sufficient sulfur, but it leaches easily. On the North Coast, atmospheric sulfur from seaspray is a significant source. Superphosphate, gypsum, elemental sulfur, and sulfate of ammonia are common sulfur fertilizers.

Trace Elements: Iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), and molybdenum (Mo) are trace elements required by plants in smaller quantities. Iron is readily available in acid soils, while manganese can be toxic in very acidic soils. Copper deficiency can occur in red soils, and overuse of molybdenum can cause copper deficiency in animals. Zinc is easily available in acid soils but can combine with iron in red soils. Boron deficiency is common in North Coast soils used for horticulture and can be remedied with borax. Molybdenum is particularly needed by legumes for nitrogen conversion and can be applied through various sources.

Understanding the essential plant nutrients and their roles in plant growth is crucial for maintaining healthy crops and pastures. By providing the necessary nutrients, plants can grow vigorously, resist diseases, and produce high-quality fruits and vegetables.
