VitaFer MACRO K

Mineral fertiliser for the intervention and preventive supply of potassium, nitrogen and phosphorus. 

Density 1.25 kg/l 

pH 5.5 – 7.5 

Description

Recommendations for use:

– in order to quickly replenish nutrient deficiencies, especially in times when the natural uptake by the root system is disrupted, e.g. by unfavourable weather conditions. 

– to stimulate the development of the root system and aboveground biomass, 

– to increase drought resistance by ensuring proper water management in the plant  

– to increase disease resistance (e.g. potato blight),  

– to ensure proper flower bud formation, flowering and fruiting, 

– in order to increase the quantity and quality of the yield, improve the storability of, among other things, vegetables and fruit. 

The role of potassium in crops: 

  • is responsible for the quantity and quality of the yield 
  • participates in the regulation of nitrogen uptake 
  • is responsible for the water management in plants 
  • contributes to building resilience to drought conditions 
  • promotes the development of the root system and the uptake of other nutrients from the soil 
  • increases the frost resistance of plants 
  • is involved in the formation of starches and sugars. 

Potassium deficiencies result in:

  • Inability to defend themselves against drought stress: plants lose their turgor and start to wilt
  • Yellowing of leaves progressing from the edges. Over time, the leaves wilt, turn brown and die
  • The plants are smaller, with a shorter and more flaccid stem
  • Delayed flowering, flowers are noticeably smaller
  • Limited ear and cob formation, poor grain pouring

Dosage and timing of application:

Fertigation – concentration up to 0.3%
