WATER TRANSPORT+PYQS

Hydraulic conductivity decreases when soil water potential:

That points to C: Decreases. Compared with the other options, Decreases is the one that correctly describes the WATER TRANSPORT concept. The wrong ones are A) Increases; B) Remains constant; D) Becomes zero. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

WATER POTENTIAL+PYQS

Water potential of saline soil is mainly affected by:

Ψs (C) is correct here. This is core WATER POTENTIAL: once you know the definition or pathway step, Ψs is the clear fit. The wrong ones are A) Ψp; B) Ψg; D) Ψm. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
