Soil Compaction and Controlled Traffic Farming | GAKI CAF-022 A two-minute, caption-led educational film connecting field observations with root-zone structure, pore connectivity and controlled traffic planning. The film explains why visible ruts are only one clue, why moisture must be recorded during assessment, and why planned wheel lanes and targeted diagnosis matter. Visual disclosure: this edition uses eleven previously created AI field/soil images and five original qualitative diagrams. It contains no real field photographs, no microscopy footage and no measured treatment comparison. Images include illustrative maize and soybean settings and must not be treated as one continuous field experiment. Camera movement is a slow pan or zoom over still images; machinery and organisms are not shown in live motion. Format: 120 seconds, 1920 x 1080, 24 fps, H.264 MP4. Large Simplified Chinese and English captions are burned into the picture. No narration, music or audio track. This is educational material pending specialist review, not a universal machinery setup or farm-specific soil diagnosis. Source references and asset provenance accompany the local production package.

Short description: From wheel ruts to the root zone: a bilingual guide to observing compaction, planning field traffic and checking results.
