What Is Haifa Water Soluble Fertilizer?
AgriFirst's listed Haifa water-soluble portfolio includes Poly-Feed NPK fertilizers and straight fertilizers based on calcium nitrate, mono ammonium phosphate, mono potassium phosphate, magnesium nitrate and potassium sulphate, each serving a distinct nutrition requirement.
All products covered in this guide are fully water-soluble. Their application routes differ: several are used primarily through drip fertigation, selected products also allow foliar application, and Poly-Feed Foliar is specifically designed for crop-canopy spraying.
- Haifa Cal GG Classic: water-soluble calcium nitrate with a 15.5-0-0 + 26.5% CaO composition.
- Haifa MAP: mono ammonium phosphate with a 12-61-0 composition.
- Haifa MKP: mono potassium phosphate with a 0-52-34 composition.
- Haifa Mag: water-soluble magnesium nitrate containing 11-0-0 + 16% MgO.
- Haifa SOP GG: water-soluble potassium sulphate containing 0-0-50 + 18% S.
- Poly-Feed Foliar: foliar-grade water-soluble NPK combined with micronutrients.
- Poly-Feed GG: greenhouse-grade water-soluble NPK with micronutrients for drip fertigation.
Selection should begin with the crop's nutrient requirement, growth stage and intended application method rather than assuming that every water-soluble fertilizer serves the same purpose.
Why Are There Different Haifa Water Soluble Fertilizers?
Haifa water-soluble fertilizers differ because nutrient needs, crop stages and application routes vary. Root establishment, flowering, calcium or magnesium nutrition, chloride-sensitive conditions, foliar supplementation and stage-based NPK feeding each require a different formulation.
For example, Haifa MAP combines phosphorus with nitrogen and is associated mainly with early rooting and establishment. Haifa MKP supplies phosphorus with potassium but no nitrogen. Haifa Cal GG Classic and Haifa Mag address different secondary-nutrient requirements, while Poly-Feed GG and Poly-Feed Foliar differ primarily in their feeding methods.

Which Haifa Water Soluble Fertilizer Fits the Requirement?
Selection of a Haifa water-soluble fertilizer should begin by identifying the nutrient requirement, crop stage and application need. Crop, soil, water quality and growth stage are also stated factors for developing a crop-specific feeding schedule.
Is Calcium Nutrition Required?
Haifa Cal GG Classic is the listed calcium-nutrition option. Its 15.5-0-0 + 26.5% CaO calcium nitrate formulation supplies calcium together with nitrate-nitrogen and is applied through drip fertigation.
Is the Crop in the Early Rooting or Establishment Stage?
Haifa MAP is positioned for early rooting and establishment. Its 12-61-0 mono ammonium phosphate composition supplies phosphorus together with nitrogen and can also be used through the vegetative phase.
Is Phosphorus and Potassium Needed Without Nitrogen?
Haifa MKP is the listed phosphorus-and-potassium option without nitrogen. Its 0-52-34 composition is positioned mainly for flowering and fruit development and can be supplied through drip or foliar application.
Is Magnesium Nutrition Required?
Haifa Mag supplies magnesium together with nitrate-nitrogen through its 11-0-0 + 16% MgO magnesium nitrate composition. It can be used by drip fertigation or foliar application where magnesium deficiency is present.
Must Chloride Be Avoided While Supplying Potassium and Sulphur?
Haifa SOP GG supplies potassium and 18% sulphur with zero chloride through a 0-0-50 + 18% S formulation. It is positioned for chloride-sensitive crops, saline conditions and drip-fertigation situations requiring sulphur.
Is Fast Foliar Nutrition Required?
