Water soluble fertilizers contain one of the three main nutrients: nitrogen, phosphorus or potassium. This allows you to apply the fertilizer in a targeted manner in case of symptoms of deficiency of the substances. Royal Brinkman offers a wide range of water soluble fertilizers. Our product range includes the following product groups:

• NPK Fertilizers
• Straight Fertilizers

Water-soluble fertilizers dissolve completely in water. They allow for easy and efficient application through irrigation systems or directly into the soil. These fertilizers contain essential nutrients like nitrogen, phosphorus, and potassium. Trace elements are often included. All nutrients are in a form that plants can absorb immediately. This makes water-soluble fertilizers ideal for professional growers.

Straight fertilizers contain only one primary nutrient. Examples include nitrogen (N), phosphorus (P), and potassium (K) fertilizers. These products are ideal for targeted use when there is a specific nutrient deficiency. Single water-soluble fertilizers and liquid forms are both available.

NPK fertilizers contain the three main nutrients essential for plant growth: nitrogen, phosphorus, and potassium. These fertilizers are available in different ratios to meet the specific needs of various crops or growth stages. By combining these nutrients in a single product, NPK fertilizers provide balanced and convenient nutrition for plants.
