Nutrient Management in Strawberry Cultivation

The video tutorial by Kristen Hicks from the NCDA covers plant tissue analysis in strawberries, focusing on optimizing fertility through tissue and petiole sampling. It explains how to collect samples, interpret reports, and manage fertility by monitoring nutrient levels. The tutorial also addresses common nutrient deficiencies like nitrogen, sulfur, magnesium, and boron, providing corrective actions for each. The importance of the nitrogen to sulfur ratio and its impact on plant health is highlighted, along with specific recommendations for nutrient management in different soil conditions.

What is the primary purpose of plant tissue tests in high-value crops like strawberries?

• To determine the best time for harvesting

• To evaluate the nutrient status of the crop

• To identify pest infestations

• To improve the taste of the fruit

Which leaf should be selected for tissue sampling in strawberries?

• The oldest leaf

• The leaf in the middle

• The most recently mature leaf with petiole

• The leaf closest to the ground

Why is it important to accurately record the number of weeks since the first bloom?

• To ensure the strawberries are sweet

• To receive the correct nutrient recommendations

• To predict the weather conditions

• To determine the best irrigation schedule

What is the most common nutrient deficiency found in strawberry leaf tissue samples in North Carolina?

• Magnesium

• Sulfur

• Nitrogen

• Boron

What is the recommended corrective action when both nitrogen and nitrate levels are low in strawberries?

• Add more potassium

• Apply more water

• Increase nitrogen application

• Decrease nitrogen application

What is the effect of an imbalanced nitrogen to sulfur ratio in strawberries?

• Enhanced fruit size

• Improved fruit color

• Reduced ability to utilize nitrogen

• Increased pest resistance

What is the primary indicator for nitrogen recommendations in strawberries?

• Petiole nitrate levels

• Soil pH

• Fruit size

• Leaf nitrogen levels

What is a common symptom of boron toxicity in strawberries?

• Bronzing of the leaf

• Delayed flowering

• Yellowing of leaves

• Increased fruit sweetness

What is the recommended form of sulfur application when sulfur is low in strawberry leaves?

• Sulfur granules

• Sulfur powder

• Epsom salts

• Sulfuric acid

What is the corrective action for magnesium deficiency in strawberries?

• Apply 10 pounds of Epsom salt per acre per week

• Add more phosphorus

• Increase nitrogen application

• Reduce watering frequency
