Lesson 1Reforestation and agroforestry options for steep or marginal land: species, shelterbelts, alley cropping basicsThis section explores reforestation and agroforestry options for marginal or steep land. It covers species selection, shelterbelts, alley cropping, and how trees can reduce erosion while providing shade, habitat, and products.
Identifying marginal and erosion-prone areasChoosing tree and shrub species mixesDesigning shelterbelts and windbreaksAlley cropping layout and spacingIntegrating livestock with silvopastureLesson 2Gully repair and rill treatment: small-scale check dams, rock/log structures, vegetative stabilisationThis section addresses diagnosing and repairing rills and gullies before they expand. It explains causes, small check structures, reshaping, revegetation, and how to prevent recurrence through improved drainage and cover.

It covers mapping contours, row orientation, contour buffer strips, grade control, and how to integrate machinery traffic with contour systems.

It addresses stocking density, paddock layout, temporary fencing, rest periods, and exclusion of sensitive riparian and wet areas from routine grazing.

It details buffer width rules, vegetation layers, livestock exclusion, and bank stabilisation methods suited to mixed crop–livestock operations.

It explains strip orientation, width, crop sequencing, and integration with common corn, soybean, and vegetable rotations.

It addresses species traits, seeding windows, mixtures, seeding methods, and termination options compatible with cash crops and livestock grazing.

It compares strip-till, reduced till, and no-till, sets residue targets, and discusses equipment setup, compaction, and residue distribution.

It reviews terrace types, spacing, outlet design, construction basics, and how to maintain structures while keeping equipment access and drainage functional.
