Three important plant nutrients
• Nitrogen (N): 2- 4% plant dry weight, essential for plant growth.
• Phosphorous (P): should be 0.25 -0.4% dry weight, for structural elements
• Potassium (K): 1.5- 2.5% dry weight, critical for early plant development

Analysis of Petioles and Leaves
• Leaf analyis gives us N-P-K concentrations in the plant, while petiole analysis gives us the state of the nitrate not yet assimilated. In other words, it is not yet incorporated.
![Page 13: Petiole and Leaf Analysis in Strawberry](https://reader031.vdocuments.us/reader031/viewer/2022020213/5885d4251a28aba67d8b6e49/html5/thumbnails/13.jpg)
Difference between the use of petiole and leaf analysis.
• Petiole analysis is more sensitive to changes in soil nitrate, while leaf analysis gives the nutritional state of the plant.
• Petiole analysis will also be affected by changes in temperature, solar radiation and soil moisture.

How to take samples for nutrient analysis
• Diagnostics
Take samples around symptomatic plant, then take samples from around non symptomatic plant.
• 15 a 20 leaves and petioles are sufficient for each sample.
• Send whole petioles.
![Page 28: Petiole and Leaf Analysis in Strawberry](https://reader031.vdocuments.us/reader031/viewer/2022020213/5885d4251a28aba67d8b6e49/html5/thumbnails/28.jpg)
Preferred area for
leaf sampling.
These are leaves of
middle age.

Conclusion
• Yes, tissue analyses give us an idea of what the nutritional state of the plant is.
• It is important for us to take samples which provide us with the maximum of information.
