{"cited_by_count":980686,"description":"This cluster of papers explores the effects of soil compaction on crop production, particularly in the context of no-till and integrated crop-livestock systems in subtropical regions. It investigates soil physical properties, soil degradation, gypsum and lime application, and their impact on root growth and overall soil quality.","display_name":"Soil Management and Crop Yield","domain_id":"1","external_ids":{"openalex":"https://openalex.org/T12792","wikipedia":"https://en.wikipedia.org/wiki/Soil_compaction"},"field_id":"11","id":"T12792","keywords":[{"display_name":"soil compaction","id":"soil-compaction","score":0.2978,"url":"https://openalex.org/keywords/soil-compaction"},{"display_name":"no-tillage","id":"no-tillage","score":0.3844,"url":"https://openalex.org/keywords/no-tillage"},{"display_name":"soil physical properties","id":"soil-physical-properties","score":0.357,"url":"https://openalex.org/keywords/soil-physical-properties"},{"display_name":"soil structure","id":"soil-structure","score":0.3002,"url":"https://openalex.org/keywords/soil-structure"},{"display_name":"conventional tillage","id":"conventional-tillage","score":0.4198,"url":"https://openalex.org/keywords/conventional-tillage"},{"display_name":"tillage","id":"tillage","score":0.2397,"url":"https://openalex.org/keywords/tillage"},{"display_name":"soil bulk density","id":"soil-bulk-density","score":0.2389,"url":"https://openalex.org/keywords/soil-bulk-density"},{"display_name":"tillage systems","id":"tillage-systems","score":0.4343,"url":"https://openalex.org/keywords/tillage-systems"},{"display_name":"soil management","id":"soil-management","score":0.2183,"url":"https://openalex.org/keywords/soil-management"},{"display_name":"soil porosity","id":"soil-porosity","score":0.3218,"url":"https://openalex.org/keywords/soil-porosity"},{"display_name":"reduced tillage","id":"reduced-tillage","score":0.4038,"url":"https://openalex.org/keywords/reduced-tillage"},{"display_name":"soil aggregate stability","id":"soil-aggregate-stability","score":0.3553,"url":"https://openalex.org/keywords/soil-aggregate-stability"},{"display_name":"liming","id":"liming","score":0.2135,"url":"https://openalex.org/keywords/liming"},{"display_name":"conservation tillage","id":"conservation-tillage","score":0.402,"url":"https://openalex.org/keywords/conservation-tillage"},{"display_name":"conservation agriculture","id":"conservation-agriculture","score":0.2635,"url":"https://openalex.org/keywords/conservation-agriculture"},{"display_name":"Oxisol","id":"oxisol","score":0.2126,"url":"https://openalex.org/keywords/oxisol"},{"display_name":"soil penetration resistance","id":"soil-penetration-resistance","score":0.6378,"url":"https://openalex.org/keywords/soil-penetration-resistance"},{"display_name":"crop residue management","id":"crop-residue-management","score":0.2151,"url":"https://openalex.org/keywords/crop-residue-management"},{"display_name":"soil density","id":"soil-density","score":0.2271,"url":"https://openalex.org/keywords/soil-density"},{"display_name":"penetration resistance","id":"penetration-resistance","score":0.2979,"url":"https://openalex.org/keywords/penetration-resistance"},{"display_name":"soil quality indicators","id":"soil-quality-indicators","score":0.266,"url":"https://openalex.org/keywords/soil-quality-indicators"},{"display_name":"soil aggregation","id":"soil-aggregation","score":0.2801,"url":"https://openalex.org/keywords/soil-aggregation"},{"display_name":"macroporosity","id":"macroporosity","score":0.3049,"url":"https://openalex.org/keywords/macroporosity"},{"display_name":"subsoiling","id":"subsoiling","score":0.5387,"url":"https://openalex.org/keywords/subsoiling"},{"display_name":"soil physical quality","id":"soil-physical-quality","score":0.7395,"url":"https://openalex.org/keywords/soil-physical-quality"}],"legacy_keywords":["Soil Compaction","No-till Crop Production","Soil Physical Properties","Integrated Crop-Livestock Systems","Subtropical Soils","Soil Degradation","Soil Management","Gypsum and Lime Application","Root Growth","Soil Quality"],"openalex_id":"https://openalex.org/T12792","source_created_date":"2024-01-23T15:27:15","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1111","url":"/topics/T12792","works_api_url":"https://api.openalex.org/works?filter=topics.id:T12792","works_count":110418,"label":"Soil Management and Crop Yield","provider":"openalex","revision":"82a9ce2be135e8e9","taxonomy_revision":"f050b5d4780b1289","title":"Soil Management and Crop Yield","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38285031596926055","address_version":"morton4x16-v1","coordinates":[1,11,1111,12792],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
