Haifa Bonus™ for better yields and plant health in Soybean

Foliar application of potassium fertilizers is a well-established practice in soybean production that has been proven to increase yields by up to 20%.

To allow for safe foliar sprays with enhanced efficiency Haifa has developed a special formula. Based on Multi-K™ potassium nitrate, Haifa Bonus™ (K 6219) foliar formula, enables spraying of highly concentrated
solution without scorching. Haifa Bonus™ is enriched with phosphorus which serves as a nutrient and reduces the pH of the solution to about 6, thereby making it compatible for tank mixing with a large variety of agrochemicals.

 

The advantages of Haifa Bonus™

  • Enables high spray concentration
  • Compatible with diverse pesticides; enabling tank mixing for spray operations savings
  • Consists of pure, fully soluble nutrients only
  • Free of sodium and chloride

 

Haifa Bonus™ is based on Haifa’s Multi-K™ potassium nitrate. Potassium nitrate contains 100% plant macronutrients: potassium (K) and nitrate-nitrogen (N-NO3). Plants absorb both the potassium and the nitrate rapidly, in a balanced manner. The similar uptake rates of these two ions improve the movement of both potassium and nitrogen in the plant, thus enhancing plant nutrition. Potassium nitrate is free of chloride,
sodium and any other elements which are detrimental to plants.

 

 

Application recommendations

 

 

Tips for a successful foliar fertilization

  • Spray during the cooler and more humid hours of the day
  • Spray when wind is low
  • Never spray plants under stress
  • Test for possible side-effects or phytotoxicity by a small trial, spraying a week prior to the intended commercial
    treatments
  • After spraying rinse the sprayer and all its parts thoroughly with fresh water

 

Preparation of tank mix

  • Fill 1/4 - 1/3 of the spray tank with water. Add the entire amount of the fertilizer(s) and then fill up the tank with water.
  • When preparing tank mix that includes pesticides, it is advisable

- To keep the pH of the spray solution at level of 5.5 -6.5, to avoid alkaline hydrolysis of the pesticides. Note: In general, Haifa’s foliar products are 

   slightly acidic, requiring lower rates of acid to set the pH of the spray solution.

- To perform a compatibility test of the spray-mix prior to large-scale treatment.
