Sustainability of crop production systems depends on the preservation of soil physical quality over time. This study aimed to determine long-term effects of soil tillage and cropping systems on physical attributes and hydraulic properties of an Oxisol in Southern Brazil, emphasising management practices to preserve or improve the soil structure quality under no-tillage system. The experiment was conducted in randomized block design, using a 5 × 2 factorial arrangement (tillage × cropping systems), with four replications. The five tillage systems consisted of conventional tillage (CT); minimum tillage, chiselled soil every year (MTC1); minimum tillage, chiselled soil every three years (MTC3); continuous no-tillage for 11 years (NT11); and continuous no-tillage for 24 years (NT24). The two cropping systems consisted of annual crop sequence with wheat in the winter and soybean in the summer, designated as crop succession (CS); and a 4-year crop rotation (CR) with white lupine-maize?black oat-soybean?wheat-soybean? wheat-soybean in winter?summer, respectively. Undisturbed soil cores were collected from 0?0.10; 0.10?0.20 and 0.20?0.30 m of soil depth, to determine the soil bulk density (BD), total porosity, macroporosity, microporosity, pore size distribution and classes, soil water retention curve, infiltration rate and field-saturated hydraulic conductivity. There was no interaction between tillage and cropping systems, and no effects of cropping systems on soil physical and hydraulic properties. Regardless the cropping system, chiselling effects on soil physical properties persisted for less than 22 months, and were restricted to below 0.20 m soil depth. The CT resulted in soil pulverization at 0?0.10 m depth, leading to lower BD and higher macroporosity compared to the other soil tillage systems. At layers below 0.10 m, CT increased the BD and reduced the macroporosity to critical levels for crop growth. Continuous use of no-tillage improved soil physical quality mainly at deeper layers, and provided higher plant available water retention in the soil at matric potentials ranging from ?10 to ?200 kPa in relation to CT and MTC1. The adoption of NT improves soil physical quality and plant available water over time, and periodic soil chiselling aiming to disrupt compacted layers should be avoided because of its effects on reducing soil compaction level are short-lived.

Recommended planting season for rhizoma peanut (RP; Arachis glabrata Benth.) is January through March. Land area planted to RP annually has increased, requiring custom planters to extend planting beyond that period, and variation in rhizome quality and establishment success have been reported. The objectives of this study were to determine how shoot and root-rhizome characteristics of four RP entries (?Florigraze?, ?Ecoturf?, ?UF Peace?, and ?UF Tito?) vary during a February through August planting period and relate these changes to subsequent establishment performance in the field near Citra, FL. Herbage mass (HM), leaf area index (LAI), and root-rhizome mass (RM) were quantified biweekly in RP nursery plots of all four entries. Rhizomes were planted at the same dates (PD), and emerged shoot number (ESN) and RP ground cover (GC) were quantified 12 wk after planting. At all sampling dates (SD), Florigraze RM was less than the other entries. Variation in RM for Ecoturf, UF Peace, and UF Tito followed similar trends, decreasing slightly between the first two SD, followed by an increase to the greatest values recorded at the third SD, after which, RM plateaued. The LAI of all entries increased at a relatively slow constant rate until the sixth SD, after which it approximately doubled by the seventh. Florigraze presented the smallest LAI throughout. Variation in HM for all entries followed similar trends, increasing at relatively constant rates throughout the period, with Florigraze HM consistently being least. Shoot number and GC were least for the second PD, reflecting low RM at that date, GC was greatest following the fourth PD, and ESN was greatest at PDs one, four, and five. Florigraze ESN and GC were least at all PD. Early results suggest RP entry has greater effect on establishment performance than specific shoot or root-rhizome characteristics, but research is ongoing.
