The aim of the research was to assess the quality of organic matter contained in sewage sludge composting products and their co-composting with fly ash and mineral wool. The object of the research were composts produced using stabilized sewage sludge from the municipal sewage treatment plant (SS_1C) and sewage sludge with the addition of 20% (SSF_2C) and 30% (SSF_3C) of fly ash and 5% (SSW_4C) and 10% (SSW_5C) of mineral wool. Selected physicochemical properties, fractional composition of humic compounds, and the degree and rate of humification were determined in compost samples taken after 180 days of composting. The reaction of the evaluated composts was close to optimal for mature composts. Co-composting of sewage sludge with mineral wool and ash increased the sorption capacity in composts compared to SS_1C. Due to the content of available P and Mg, the discussed composts formed the SS_1C>SSF_2C and SSF_3C>SSW_4C and SSW_5C series. However, in terms of available K content: SSF_2C and SSF_3C>SSW_4C and SSW_5C>SS_1C. In the SS_1C compost the organic carbon (TOC) content was slightly higher, but no statistically significant effect of the addition of fly ash and mineral wool on the TOC content in mature composts was confirmed. The addition of ash and mineral wool significantly increased the total nitrogen content. Due to the humification index, the composts formed the series: SSW_4C > SSW_5C > SSF_2C > SS_1C > SSF_3C. The values of the C-KH/C-KF ratio in SS_1C were typical for good quality soils, while in the remaining composts the C-KH/C-KF values were slightly lower. The degree of humification of the assessed composts was characterized by poorly humified organic materials, with the highest values of this indicator found in composts with the addition of mineral wool. The assessed quality indicators of organic matter indicate that the organic matter of composts from sewage sludge with the addition of mineral wool and 100% sludge was of the highest quality.

Turfgrass research based on inoculations with commercial products containing nitrogen‐fixing endophytes as an alternative to synthetic nitrogen (N) fertilizers has yielded inconclusive results, indicating a lack of understanding of the colonization and stability of diazotrophic endophytes in turfgrasses. Potential factors influencing these results are turfgrass traditional management practices. In this study, we identified and compared endophytic diazotrophic communities and their associated soil counterparts using amplicon sequencing of the nitrogenase iron protein (nifH) of 36 surfaced sterilized CitraBlue St. Augustinegrass cultivar [Stenotaphrum secundatum (Walter) Kuntze] sprigs and 12 aggregated soil samples. Samples were collected from a CitraBlue cultivar mowed either at 5 or 10 cm, with and without thatch removal, and fertilized at 98, 195, or 293 kg N ha−1 year−1. The different communities of endophytic diazotrophs were correlated to turfgrass quality related parameters such as normalized difference vegetation index (NDVI), normalized difference red edge index (NDRE), N leaf content, and visual quality as affected by management practices. CitraBlue endophytic and soil diazotrophic communities were significantly different for alpha diversity (p < 0.0001) and beta diversity (p < 0.001). Both mowing height (p < 0.001) and N fertilization rate (p < 0.05) had a significant effect on the diversity of endophytic diazotrophs. According to the redundancy analysis, turfgrass quality related parameters explained 14.3% of the variance in the endophytic diazotrophic communities. Findings from this research demonstrate that the evaluated management practices alter the endophytic diazotrophic communities of CitraBlue.

Slow-release fertilizer is generally used in turfgrass management to maintain quality turf without inducing excess vertical growth, to avoid frequent mowing. This study was designed to verify whether kitchen waste digestate and digestate biochar could serve as slow-release fertilizers to promote turf quality and reduce nutrient leaching risk in two turfgrass species over two years in controlled pot experiments. The results showed that the nutrient release of granular fertilizers made from kitchen waste digestate and digestate biochar was a two-phase process (an initial rapid phase, followed by a slow-release phase). The kitchen waste digestate showed higher nitrogen and phosphorus release ratios than the biochar and sheep manure. Compared to the reference sheep manure, fertilization with kitchen waste digestate and biochar increased the leaf chlorophyll content by 48.6% and 27.9%, and reduced senescent leaves by 15.6% and 11.1%, respectively, at 23 d after fertilization, leading to higher turf quality. Fertilization with kitchen waste digestate biochar significantly reduced the nutrient leaching risk compared to fertilization with kitchen waste digestate and sheep manure. Our results demonstrated the potential of reusing kitchen waste digestate and digestate biochar as slow-release fertilizers for promoting turf quality in turfgrass management.
