Nutrients

Question 1

5 vital nutrients

Answer 1

Nitrogen
Calcium
Phosphorus
Magnesium
Potassium

Question 2

Nitrogen purpose

Answer 2

(Green growth)
- vine growth
- grape quality
- component of proteins and chlorophyll needed for photosynthesis

Question 3

Nitrogen impact

Answer 3

Too much = excessive vigor

Too little = reduced vigor, yellow leaves, stuck fermentations

Question 4

Calcium purpose

Answer 4

(Green growth)
- structure of plant cells
- photosynthesis

Question 5

Calcium impact

Answer 5

Too little (rare) = poor fruit set

Question 6

Phosphorus purpose

Answer 6

(Green growth)
- photosynthesis

Question 7

Phosphorus impact

Answer 7

Too little (rare) = poorly developed root system (reduced water/nutrient uptake), reduced vine growth, and lower yields

Question 8

Magnesium purpose

Answer 8

(Green growth and grape development)
- photosynthesis

Question 9

Magnesium impact

Answer 9

Too little = reduced yield, poor ripening

Question 10

Potassium purpose

Answer 10

(Grape development)
- vine growth
- regulates flow of water in the vine

Question 11

Potassium impact

Answer 11

Too much = problems with magnesium uptake, high levels of K in the vine which correlates with pH

Too little = low sugar accumulation, reduced yields, and poor vine growth
