Discuss THREE factors that contribute to relationships that are detrimental to your well-being.

Soil salinity is classified using electrical conductivity (EC) as follows:

• $0 - 2$ dS/m: Non-saline
• $2 - 4$ dS/m: Slightly saline
• $4 - 8$ dS/m: Moderately saline
• $8 - 16$ dS/m: Highly saline
• $>16$ dS/m: Very highly saline

Given: $EC = 0.4$ dS/m
$0.4 < 2$, so the soil is non-saline.
Non-saline

Soil sodicity hazard based on SAR:

• SAR $< 3$: Low (S1)
• $3 \leq$ SAR $< 9$: Moderate (S2)
• SAR $\geq 9$: High (S3)

Given: SAR $= 3.2$
$3 \leq 3.2 < 9$, so the soil sodicity is moderate (S2).
Moderate (S2)

Soil sodicity based on ESP:

• ESP $< 15\%$: Non-sodic
• ESP $\geq 15\%$: Sodic

Given: ESP $= 12\%$
$12\% < 15\%$, so the soil is non-sodic.
Non-sodic

Soil pH classification:

• pH $< 8.5$: Non-alkaline
• $8.5 \leq$ pH $< 9.0$: Slightly alkaline
• pH $\geq 9.0$: Strongly alkaline

Given: pH $= 7.2$
$7.2 < 8.5$, so the soil is non-alkaline.
Non-alkaline

Soil texture classification for physical condition:
Loam texture has balanced proportions of sand, silt, and clay, providing good structure, water retention, aeration, and drainage.

Given: Texture = loam
Thus, the soil has a suitable physical condition.
