Crops in this Family: Canola, Cabbage, Mustard, Broccoli, Cauliflower, Turnips, Brussels Sprouts, Camelina
Below is a tissue nutrient sufficiency table for the Mustard Family (Brassicaceae), which includes crops like canola (Brassica napus), cabbage (Brassica oleracea), and mustard greens (Brassica juncea). This table provides macro- and micronutrient sufficiency ranges, leaf water content (LWC), and Brix values across key growth stages. Since nutrient sufficiency data vary slightly across Brassicaceae species, this table is primarily based on canola (a well-studied member) and generalized for the family, with adjustments informed by data on other brassicas (e.g., from the University of Manitoba, Cornell University, and other sources).
Growth stages are defined as:
- Vegetative (rosette to stem elongation)
- Flowering (bloom)
- Fruit/Pod Development (pod or head formation)
- Maturation (pod ripening or harvest)
- Harvest
Nutrient concentrations are in percentages (%) for macronutrients and parts per million (ppm) for micronutrients, with LWC as a percentage of fresh weight and Brix (°Bx) as soluble solids in leaf sap.

Scanning Recommendation:
- Leaf selection should be similar to that of Canola.
- Ensure that over 25% of the scan bed is covered with a single layer of vegetation.
