VitaFer KOMBI

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

Density 1.38 kg/l

pH 6.0 – 7.5

Description

Recommendations for use: 

– for preventive and intervention supplementation when a deficit becomes apparent. 

– where the natural uptake of nutrients from the soil is impaired, e.g. by adverse weather conditions 

– in crops with high nitrogen/potassium requirements.  

– to increase resistance to stress caused by drought, disease and the consequences of insect foraging 

– to optimise bud formation, flowering and fruiting processes 

– to improve the size and quality of the crop, to improve the taste of fruit and vegetables and to improve storage quality.          

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. 

The role of nitrogen in crops: 

  • building material for proteins and nucleic acids 
  • ensures proper development of plants: roots and above ground parts 
  • important constituent of chlorophyll, vitamins, hormones and DNA 
  • has a beneficial effect on optimum vegetation length: flowering and yielding 
  • improves water management in plants, increases drought tolerance. 
  • stimulates the development of the root system and increases the absorption of nutrients from the soil 

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

Nitrogen deficiencies result in:

  • Light green color of leaves and plant stems in extreme deficiency turning into yellow discoloration of leaves
  • Abnormal, reduced plant habit
  • Poorly formed fruit, pods, or ears
  • Accelerated maturation
  • Increased susceptibility to fungal diseases and the effects of insect feeding

Dosage and timing of application: 

Attention: The fertiliser must not be mixed with phosphate fertilisers.
