Magnesium deficiency made worse by

  • Sandy soils
  • Acidic soils
  • Potassium rich soils
  • Soils receiving high potash applications
  • Cold wet periods

Magnesium is important for

  • Boosts bulking
  • Increased yield of tubers

YaraVita CROP BOOST

Potatoes: To stimulate early growth: 10 l/ha one week after 100 percent crop emergence. To increase tuber number: 10 l/ha at tuber initiation (when 50 percent at the tip swellings are twice the diameter of the rest of the stolon). To increase tuber size: a minimum of 2 applications of 5 l/ha during tuber bulking ( as soon as first formed tubers are 10mm in diameter) and following petiole analysis during tuber bulking. Allow 10 to 14 days between applications. Water rate: 200 l/ha.
