Short field and soft field techniques solve two genuinely different problems, one is about squeezing maximum performance out of a limited runway length, the other is about protecting the airplane and keeping it moving on a surface that doesn't want to let it roll freely, and confusing the two, or blending them without understanding why each control input exists, is where most of the common mistakes come from.
A short field problem is about distance: the runway (or the useful part of it) is short, and the goal is clearing obstacles and stopping within the available length, on a surface that's otherwise perfectly firm. A soft field problem is about surface friction and structural risk: mud, sand, grass, or snow that resists rolling and can even damage the landing gear or flip a nosewheel aircraft forward if too much weight sits on the nose gear during the roll. The two techniques share some elements but solve fundamentally different problems.
Minimize ground roll and maximize the climb angle (not necessarily climb rate) over the first obstacle, since a short field is often paired with obstacles at the departure end. This distinguishes a short field takeoff from a normal one, which typically optimizes for a comfortable climb rate rather than the steepest possible angle over a specific point.
Use the full available runway length, back to the very start, holding brakes while applying full power (where the POH calls for it) to reach maximum thrust before releasing brakes, use the flap setting specified in the POH for short field takeoffs (often a specific partial flap setting, not zero and not full), and climb out at VX (best angle of climb speed) until clear of any obstacle, then transition to VY (best rate of climb) for the remainder of the climb.
Land as close as possible to a specific point (often simulating clearing an obstacle on short final) and stop in the shortest practical distance, prioritizing precision and a firm, controlled touchdown over the soft, extended flare of a normal landing.
Fly a stabilized approach at the POH's specified short field approach speed (typically slower than a normal approach, closer to the aircraft's actual stall margin), use full flaps for the steepest practical approach angle and lowest possible touchdown speed, aim to touch down at a specific point rather than "somewhere on the runway," and apply firm braking (and, where applicable, retract flaps for better brake effectiveness on the roll) immediately after touchdown, without floating for a smooth landing feel.
Get the aircraft's weight off the wheels and rolling as smoothly as possible on a surface that resists rolling friction, minimizing the risk of getting stuck, damaging the gear on rough or soft terrain, or digging the nosewheel in.
Keep the aircraft moving continuously from the moment it enters the runway, no full stop for a normal runup or brake-hold, since stopping on soft terrain is exactly what risks getting stuck. Hold the elevator full aft (or as the POH specifies) during the takeoff roll to keep weight off the nosewheel, lift off at the earliest safe moment even below normal liftoff speed, and use ground effect to accelerate in level flight just above the surface before climbing away, rather than climbing immediately at a low, potentially unsafe airspeed.
Touch down as gently as possible, keeping weight off the nosewheel for as long as practical during the rollout, to avoid a hard impact or nose-gear digging into soft terrain.
Fly a normal approach speed and configuration, but hold the aircraft off in ground effect during the flare for a very soft, minimal-sink touchdown on the main wheels, then hold the elevator full aft during rollout to keep the nosewheel light for as long as possible, minimizing braking (which isn't very effective on soft terrain anyway and adds nose-down pitching moment) and instead letting the surface's own rolling resistance slow the aircraft.
