Pekacid
• A combination of MKP and white
phosphoric acid
• KH2PO4 + H3PO4 = KH5(PO4)2
• Acidic white crystalline PK fertilizer
Main Characteristics
• Highly acidic (pH=2.2)
• High purity
• High solubility (667g/L at 20°C)
• Neutralization power: 240 g PeKacid neutralizes
1 eq of HCO3- in 1 m3 water
• Absence of Nitrogen
• Sodium and Chloride free
Typical Analysis

Effect of Pekacid on Solution pH

Pekacid Acidifying Power – Enhances Nutrient Uptake
• Keeps an optimum soil and water pH
• Increases nutrients availability, especially micronutrients, phosphorus and magnesium
• Increases nutrients mobility in the root system
• Decreases nitrogen losses through volatilization
• Increases water infiltration into the soil
PeKacid Advantages: Nutrition
PeKacid can be mixed with Calcium and/ or Magnesium, results a clear solution Formulations such as :18-10-18+2% MgO or 15-5-15+7CaO+3MgO can be achieved without precipitation
PeKacid – An Efficient Acid
• The use of PeKacid will keep the irrigation:system clean, hence
• Insures reliable water and fertilizer distribution -
• Reduces labor required to clean tanks and - pipes
• Replaces alternative hazardous acids -
• Extends longevity of the irrigation system -
Alkalinity
Alkalinity is a measure of a water's capacity to neutralize acids. Bicarbonate ions (HCO3- ) from dissolved salts such as calcium bicarbonate (Ca(HCO3)2), sodium bicarbonate (NaHCO3), and magnesium bicarbonate (Mg(HCO3)2); and carbonate ions (CO3- - ) from dissolved salts such as calcium carbonate (CaCO3) are the major chemicals contributing to alkalinity in irrigation .water
50ppm CaCO3 =50 mg/L CaCO3 =1 meq/L CaCO3 =61
ppm HCO3- =61 mg/L HCO3- =1 meq/L HCO3

Titrations of two different waters with sulfuric acid. Notice that although the beginning pH of Grower A water is a full unit higher than Grower B water, it takes more than 4 times the acid )68.6 floz compared to 15.8 fl oz for Grower A water( to drop Grower B water to pH 5.8, due to the greater alkalinity in Grower B water
PeKacid For Fertigation in Open Fields Crop
PeKacid Replaces other Phosphorus and Potassium Fertilizers
PeKacid provides chlorine free phosphorus and potassium. It can replace any other source of phosphorus fertilizer such as phosphoric acid or MAP. It also replaces part of potassium .nitrate or potassium sulfate PeKacid contains no nitrogen thus a nitrogen fertilization should be added upon crop’s needs.
