STERIC: NAP's patented and proven Steric P III, K, S and MKS deliver the agronomist/crop advisor and the grower 100 percent available plant food that stays in the soil solution long-term for maximum uptake by the plant. For the past 12 years, Steric products have proven to be highly effective in hostile soils and can be applied via soil injection or any irrigation system including drip, without the risk of reacting with high bicarbonates that can cause plugging.
Steric products do not overcome soil hostility by simply applying more expensive fertilizer. Instead, the Steric chemistry shields the plant food element from known hostile effects surrounding nutrient tie-up in most soils. This is why Sterics are known for "doing more with less" compared to conventional products. Sterics are applied on a wide variety of vegetable and tree nut crops successfully year after year.
