Soil and Water: The Engine Under the Grass
SA rangeland soils start from a carbon baseline most imported regenerative content does not imagine. This module gives the honest carbon picture, turns the binomial soil form into a prediction of where water goes, identifies the piosphere as the place structure actually fails, triages erosion against two national datasets that must never be added together, and hands over four quarterly observations you can do with a spade and a ring.
- 07 SA Soils and What Soil Carbon Really Does Here Settles the actual organic carbon baseline of South African soils and what can honestly be claimed about building it. State the South African soil organic carbon distribution and use it to test any imported regenerative claimSeparate the carbon a plough took from the carbon poor veld condition is costing youSay out loud what a Highveld grassland farmer can honestly claim about building carbon, and over what period 14 min
- 08 Soil Form as a Water Forecast Settles how to read the SA binomial soil form as a prediction of where water goes, and therefore where infrastructure belongs. Assign the soil forms on your own farm to one of the five hydropedological groupsPredict where water will move, perch and accumulate from a position on the catenaSite a water point, kraal or track from the soil form rather than from where the pipe already runs 13 min
- 09 The Water Cycle Under Grazing Settles how grazing changes hydrology, and identifies the piosphere as the place where soil structure actually fails. Explain how basal cover and surface capping change infiltration on South African rangelandLocate the piosphere on your own farm and say what is happening to itState honestly what South African measurement does and does not exist on infiltration under different stocking densities 12 min
- 10 Erosion, Wetlands and the Drainage Line Settles how to triage erosion, which national datasets must never be added together, and what the law requires in a watercourse. Triage the erosion on your own farm into a cheapest-first repair orderExplain why the sheet-and-rill and gully datasets cannot be added togetherState the CARA duties that attach to a vlei, a drainage line and an eroded patch before you move any soil 13 min
- 11 Four Farm Observations and the Dung Pat Clock Settles the four no-laboratory observations, and what a dung pat that will not disappear says about your own drenching. Run four quarterly observations at fixed points using a spade, a ring and a cameraSet up a soil carbon measurement that will still be comparable in five yearsApply a macrocyclic lactone targeting and timing rule that protects dung fauna without naming a dose 13 min
