Crop Sensitivity Notes (Advanced)

Purpose

Crop sensitivity notes highlight how different crops respond to: - Salinity - Sodium and chloride - pH extremes - Nutrient imbalance - Root-zone stress

This information is context-dependent and intended for advanced interpretation.

General principles

• Young plants are more sensitive than mature plants
• Fruit crops are highly sensitive to calcium transport disruption
• Leafy crops show salinity symptoms rapidly
• Rootstocks and cultivars differ significantly in tolerance

Examples (non-exhaustive)

Calcium-sensitive crops

• Tomato
• Pepper
• Strawberry
• Lettuce

Common issues: - Tip burn - Blossom end rot - Internal breakdown

Salinity-sensitive crops

• Strawberry
• Bean
• Lettuce
• Blueberry

Sodium/chloride sensitivity

• Blueberry (very sensitive)
• Soft fruit
• Ornamentals

pH-sensitive crops

• Blueberry (low pH specialist)
• Brassicas (high Mo sensitivity at low pH)
• Ornamentals with narrow micronutrient windows

Important note

Crop sensitivity interacts with: - Root environment - Climate - Irrigation strategy - Growth stage

These notes should support decisions, not replace measurement or experience.

Pro-tier direction

Future expansion may include: - Crop-specific EC limits - Ion sensitivity tables - Rootstock differences - Growth-stage sensitivity windows
