K Blast 36 is a high analysis and low salt index solution of potassium thiosulfate, citrate and carbonate to apply potassium in a wide range of crop and soil conditions. It is especially suited to the situations where sulphur is not a major limiting factor and potassium is required at high concentration. K Blast 36 is free of nitrogen.
POTASSIUM IN PRODUCTION SYSTEMS
Potassium is a highly mobile nutrient and must be incorporated in any nutritional program. K Blast 36 the Potassium Thiosulphate, citrate and potassium carbonate solution is ideal for use on all types of crops to apply pre-dissolved and soluble potassium especially in the production systems requiring low levels of sulfur.
In cereals potassium must be applied early in the season for root uptake or through the foliage only at later stages of growth, as roots do not absorb potassium generally after anthesis/flowering.
Plants absorb potassium from the soluble potassium pool, which is located in the topsoil. This pool gets exhausted pretty quickly due to absorption of potassium by plants and soil erosion.
Application of solid or prilled potassium nitrate, potassium sulfate, potassium chloride can be damaging to the root hairs due to high salt index, may leach-out of the root zone and dissolve on run-off water. All these potassium fertilisers have very limited water solubility, thus each application requires the maintenance of adequate soil moisture especially in the root zone. This means escalated irrigation costs. Unlike other potassium products, K Blast 36 also acidifies the root zone to unlock trace elements due to sulphuric acid formation. The thiosulfate ion dissociates in soil to form sulphuric acid with the help of some sulphur bacteria.
ROLE OF POTASSIUM
Horticultural crops such as avocados, almonds, citrus, vegetables, mangoes and potatoes have high potassium requirements especially during yield formation stages of growth. Potassium draws water into the fruit, mobilizes sugars and helps in starch accumulation giving better fruit quality and production. Secondly these crops require high potassium inputs to support substantial leaf area development as a result of nitrogen application. Potassium regulates the opening and closing of stomata, the site of gas exchange for photosynthesis and water loss through transpiration. Potassium is also a component of some enzymes actively participate in photosynthetic reactions. Foliar application of potassium especially during fruit development period promotes fruit size, aroma and carbohydrate synthesis.
THE DEFICIENCY SYMPTOMS OF POTASSIUM INCLUDE:
-
Marginal and leaf tip necrosis due to the enhanced synthesis of polyamines
-
Poor quality fruit and fruit size
-
Late season blotchy chlorosis
-
Poorly developed root system
-
Plants wilt easily with imposition of marginal water stress
-
Can be conveniently applied through the drippers without blockages.
-
Can also be sprayed to improve fruit quality and size.
-
K Blast can be conveniently blended with ammonium polyphosphate to provide NPK.
-
Chloride and nitrogen free formulation ideal for most soil types.
-
Contains thiosulfate sulfur that releases sulfuric acid to acidfy root zone.
-
Optimum availability of K in heavily leached sands.
-
Pre-dissolved potassium and sulfur source that readily mix with water.
-
A high concentration of potassium in liquid form that promotes plant growth.
