Many soils require the addition of several essential nutrients to alleviate plant deficiencies. The combination (compound or complex) fertilizers can offer advantages of convenience in the field, economic savings, and ease in meeting crop nutritional needs. NPK compound fertilizers are made using basic fertilizer materials, such as NH3, ammonium phosphate, urea, S, and K salts. NPK compound fertilizer contains multiple nutrients in each individual granule, which differs from a blend of fertilizers mixed together to achieve a desired average nutrient composition. This difference allows NPK compound fertilizer to be spread so that each granule delivers a mixture of nutrients as it dissolves in the soil and eliminates the potential for segregation of nutrient sources during transport or application. Micronutrient materials can be added during NPK compound fertilizers production process, which allows a uniform distribution of micronutrients throughout the rootzone.

 

NPK Compound fertilizers are sometimes more expensive than a physical combination or blend of the primary nutrient sources since they require additional processing. However, when a consideration is made of all the factors involved with nutrient handling and use, compound fertilizers may offer considerable advantages.

 

NPK compound fertilizers are especially effective for applying an initial nutrient dose in advance of planting. There are certain ratios of nutrients available from us for specific soil and crop conditions. This approach offers advantages of simplicity in making complex fertilizer decisions, but does not allow the flexibility to blend fertilizers to meet specific crop requirements. Turf managers and homeowners often find compound fertilizers desirable.

 

Nitrogen is the nutrient that most commonly needs to be carefully managed and reapplied during the growing season. It may not be feasible to supply sufficient N in advance of planting to meet the entire demand (using only compound fertilizer) without over-applying some of the other nutrients. It may be advisable to use a compound fertilizer early in the growing season and then later apply only N fertilizer as needed.
