Potassium is an essential nutrient for grape growth, development and quality. A good supply of potassium helps plants produce high quality, high yielding grapes.

Addition of potassium to grapes

Potassium can be added to grapes by fertilizing. Potassium fertilization is usually done in spring, when the plants are in full growth phase.

The most common potassium fertilizers are potassium sulfate and potassium chloride. Potassium sulfate is the most commonly used potassium fertilizer because it is less soluble in water than potassium chloride.

The amount of potassium to be added to grapes depends on the variety, climate and growing conditions. In general, it is recommended to add between 200 and 400 kg of potassium sulfate per hectare.

Potassium deficiency in grapes

Potassium deficiency in grapes is manifested by the following symptoms:

• Yellowing or chlorotic leaves
• Rolled leaf edges
• Small berries with little pulp

Potassium deficiency can reduce grape yield and quality.

Excess potassium in grapes

Excess potassium in grapes can cause the following symptoms:

• Slow plant growth
• Leaf discoloration
• Low fruit production

Excess potassium can also reduce the absorption of other nutrients, such as calcium and magnesium.

Benefits of using a potassium meter

The use of a potassium meter is an essential tool for grape growers. A potassium meter allows growers to accurately determine the potassium content of grapes.

The use of a potassium meter offers the following benefits:

• Improves grape quality: A good supply of potassium helps grapes develop intense color, sweet flavor and firm texture.
• Increases yield: Grapes with a good supply of potassium are more resistant to disease and stress, which can lead to higher yields.
• Reduce costs: Using a potassium meter can help growers avoid over- or under-application of fertilizer, which can save money.
