Deep nitrate core
Three depth increments of a deep-nitrogen core hold their nitrate, and a parcel detaches from the surface increment and crosses the root-zone rule into the increment below.

A survey toolbar tracks down a block and an electrical-conductivity raster reports row by row behind it.
Water in a double-ring infiltrometer falls while the cumulative-infiltration curve beside it draws out and flattens onto a steady-state rate.
A buffer curve draws from the measured pH up to the target rule, a drop line marks where it lands and the lime rate bar below fills to that reading.
A volumetric water content strip scrolls under a now rule, drawing down from full point towards refill point and stepping back up at each irrigation while a reading dot rides the line.
Three arc gauges for nitrogen, phosphorus and potassium sweep to their soil-test indices in turn, each read against a critical-value tick on its arc.
Applied nutrient and crop offtake stand as paired columns for N, P and K, the accent removal column rebuilding against a rule carried across from the applied height.
Five yearly columns of soil organic carbon stacked into labile, particulate and humus fractions grow tier by tier while a trend rule lifts across their tops.
A penetrometer trace of resistance against depth redraws downward, bulging past a threshold rule where a plough pan sits and dropping a depth marker on it.
A variable-rate map resolves over its sample points into three rate zones and the marker on the legend steps up a band as each zone is written.
A capacitance probe with six sensor rings down its shaft reports moisture as horizontal bars that re-poll from the surface downward on each scan.
A filled conductivity-against-depth profile stands beside a threshold rule and a ghost of the previous survey, its salt bulge pushed down the column by the leaching fraction.
A paddock divided into sampling cells is walked in serpentine order, each cell dropping its core in turn while the composite sample rebuilds in the vessel alongside.
A needle swings down a graduated pH scale, overshoots and settles inside the target band, which brightens as the reading comes to rest.
Surface and ten-centimetre temperature traces scroll as damped, lagged waves against a germination threshold, and the marker ring on the deep trace lights while it is above the line.
