Determined by atomic absorption spectrometry or flame photometry; important for osmoregulation and activating enzymes.

Calculated from the CEC and the amounts of major base cations present; it indicates the proportion of soil CEC occupied by key nutrient cations.

Evaluated by feel or particle size analysis (hydrometer method); affects water holding capacity, aeration, and root penetration.

Measured using techniques like DTPA extraction followed by atomic absorption spectrophotometry; critical in small quantities for plant health.

Measured by soil test kits using colorimetric methods or spectrometry; essential for energy transfer and root development.

Measured in milliequivalents per 100 grams of soil; reflects the soil's ability to hold onto essential positively charged ions (cations).

Measured in dS/m using an EC meter; it quantifies the soil's salinity which can impact plant growth and microorganism activity.

Measured using a pH meter or litmus paper; indicates the acidity or alkalinity of the soil, which affects nutrient availability to plants.

Measured by loss-on-ignition or wet chemistry methods; signifies the soil's capacity to retain moisture and store nutrients.
