What is NPK fertilizer?
NPK fertilizer supplies nitrogen, phosphorus and potassium, represented by N, P and K. Bluebird NPK+S EKO has an NPK 12-3-3 formula and also contains 34% sulfur and 65% organic matter.
What are the benefits of using a chloride-free NPK fertilizer?
A chloride-free formula supplies NPK without adding chloride from the fertilizer, which is relevant when planning nutrition for chloride-sensitive crops or soils. NPK+S EKO also supplies sulfur and organic matter; crop response still depends on the soil test and the complete program.
Why choose organic-mineral NPK over traditional synthetic fertilizers?
NPK+S EKO combines organic matter and organic nitrogen with ammonium nitrogen, phosphorus, potassium and sulfur. Its description states that about 50% of nitrogen is released within the first 14 days and the rest gradually. This describes the Bluebird formulation, not a universal ranking of organic-mineral and synthetic fertilizers.
What crops benefit most from low-chloride NPK fertilizers?
NPK+S EKO is described for all types of crops, including stubble catch crops and cover crops, and it is chloride-free. The crops that benefit most from a low-chloride program depend on their chloride sensitivity, soil test and other fertilizer inputs, so a crop-specific recommendation is still needed.
