- Long-term effects of cover crops on physical-hydric properties of compacted soil Deonir Secco Doglas Bassegio Araceli Ciotti de Marins Bruna de Villa Luiz Antônio Zanão Júnior Tiago Roque Benetoli da Silva Affonso Celso Gonçalves Junior Agrociencias no till Compaction cover crop bulk density The screening of cover crops is essential for improving the physical-hydric properties of compacted soils. This study aimed to evaluate the effects of mixed or single cover crops on improving the physical-hydric properties of compacted Oxisol. Species with tap-rooted and fibrous-rooted rooting patterns were evaluated. The species included pearl millet (Pennisetum americanum), pigeon pea (Cajanus cajan), sunn hemp (Crotalaria spectabilis), velvet bean (Mucuna pruriens), white oat (Avena sativa), black oat (Avena strigosa), rye (Secale cereale), black oat + forage turnip (Raphanus sativus), black oat + white lupin (Lupinus albus L.), and black oat + group pea (Pisum arvense L.). Mixing cover crops did not improve the physical properties of the soil. The tap-rooted pigeon pea effectively reduces bulk density and increases porosity and saturated hydraulic conductivity (Ksat) in compact soils. The selection of cover crops with characteristics that improve soil physical-hydric properties is crucial for compacted areas. 2023 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303075473048 https://www.redalyc.org/journal/3030/303075473048/ https://www.redalyc.org/journal/3030/303075473048/html/ https://www.redalyc.org/journal/3030/303075473048/303075473048.epub https://www.redalyc.org/journal/3030/303075473048/movil 10.4025/actasciagron.v45i1.62390 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
