atomic number 19 – Potassium plays a cardinal role in yield set and yield caliber . If your soil has enough nutrients , the acidity level of grape is balanced and yield production increases .
Magnesium – Proper magnesium in the soil allows vines to get sorry green leaves and stems . Without an adequate amount of chlorophyll in leave and vines to provide proper aegis from the constituent , the Grapes themselves can not mature properly .

Re - see the soil every 3 years to supervise the pH floor .
If a soil test break morning star is as low as much , apply triplex phosphate at a rate of 226 Gram , superphosphate at a rate of 566 grams , or bone repast at a rate of 1 kilogram per 100 solid feet .
