Ikar Fosto

  • Ikar Fosto

Ikar Fosto – a liquid concentrated phosphorus (P) fertilizer for stimulation of physiologic processes during early development phase of plant. Though phosphorus is necessary for plants during all period of vegetation, especially this element is necessary at the beginning of growth when plant assimilates and accumulates bigger quantities of it. Phosphorus stimulates development of root system, formation of generative parts, increases productive fructification. Other substances, existing in composition of the fertilizer help plant better assimilate phosphorus or are necessary for strengthening of functions performed by phosphorus.
Phosphorus like element is little mobile within plant as well as in soil. Especially complicated assimilation pf phosphorus from soil, at low temperature of soil and air and at high or low soil pH (when pH > 7 or pH < 5,5).
In case of lack of phosphorus plants develop weakly, grow little mass, fruit less. Phosphorus is necessary for all plants, but in particular winter wheat, malt barley, peas, beans, soy, maize, rape, leguminous grass are most sensitive against lack of phosphorus.
Phosphorus stimulates:
• Germination
• Development of roots
• Formation of generative organs
• Intensity of blooming
• Budding
 • Maturation.
Phosphorus is necessary for plants during full vegetation, it cannot be replaced with other elements.


Fits for fertilizing of all plants for which additional quantity of phosphorus is necessary during vegetative period. Norm for fertilizing through leaves 0,5-1,5 l/ha.
Fertilizing of winter corns: 0,5-1,5 l/ha, after resume of vegetation to middle of nodding;
Fertilizing of summer corns, malt barley: 0,5-1,5 l/ha, to middle of nodding;
Fertilizing of maize: 0,5 -1,5 l/ha during 3-6 leaves phase; Fertilizing of peas, beans: 0,5-1,5 l/ha to height of 10-20 cm.


Possible to use in mixes with many fertilizers and pesticides (insecticides, fungicides). Do not use with products containing copper, sulphates, mineral oils, with alkaline products (pH>8). Before mixing it is recommended to make a small amount of the mix in order to define if there forms no sediments, to spray it over small site in order to define if there is no phyto-toxic influence on plants.
