The necessity of forced aeration (FA) in static windrows should be evaluated with caution since the adoption of composting cells with partially open walls can favor the process and dispense the need for aeration. We aimed to evaluate the influence of aeration and season in composting cells with perforated walls (CCPW) using bovine slaughterhouse waste (SW) associated with a bulking agent. The windrows built in winter, without (WA) and with aeration (A), maintained average temperatures of 55.8 and 57.5 °C for 66 and 53 days, respectively. This period was shorter than that observed in summer windrows (71 and 72 days, WA and W, at temperatures of 55.9 and 53.7 °C, respectively). The presence of FA in the windrows conducted in the summer did not influence (p > 0.05) the reduction of total solids (TS), C, ether extract (EE), and neutral detergent fiber (NDF) at 90 days, while the FA during the winter provided a lower degradation of the evaluated constituents (TS, C, EE, and NDF). FA did not influence N losses during the summer, but accelerated those observed in the initial composting phase during the winter (40.16 and 48.25% of N losses, at 50 and 70 days of composting, respectively), compared to WA condition (32.04 and 44.09%, respectively). FA did not minimize N losses, and also did not improve the levels of other nutrients. Thus, we can conclude that composting of SW in CCPW dispenses the use of FA during the winter or summer. |

Phosphate (Pi) availability is highly limited in the acidic soils of the Brazilian savannahs (Cerrado) used for sorghum cultivation. Although several sorghum genotypes contrasting for P use-efficiency have been developed from natural genetic variants, the Pi transport pathway mechanisms in these plants remain unclear. High-affinity Pi transporters play a pivotal role in Pi acquisition by roots and its subsequent mobilization to aerial parts of the plant. We investigated the potential roles of high-affinity Pi transporters in Pi use efficiency in contrasting genotypes of sorghum. A cDNA library prepared from Pi-deprived sorghum seedlings was screened with heterologous Zea mays (maize) Pi transporters ZmPTs, leading to isolation of two homologous sorghum genes referred to as SbPT 1 and SbPT2. Southern analysis revealed that a small gene family represents the SbPTs genes in the sorghum genome. There were significant increases in the transcription levels of SbPT1 and SbPT2 in roots of Pi-deprived seedlings of both Pi-use efficient (101B) and Pi-use inefficient (136B) genotypes. A decrease in the transcript levels of these transporters in 101B and 136B upon Pi replenishment suggested their transcriptional regulation by Pi. Although SbPT1 and SbPT2 were induced in the roots, and in young and old leaves of Pi-deprived sorghum, high transcription levels were observed exclusively in the stems of Pi-efficient genotype 101B under Pi-deprivation. This suggests a role of SbPTs in the efficient mobilization of Pi from the root to the shoot, which could be one of the factors conferring higher Pi-use efficiency in this genotype.
