“…The high correlation of TN with TC (r = 0.92) documented the general increase in the availability of macronutrients in the soil treated with manure. In addition, higher TN content in the M, M + H, and M + B treatments led to the increased plant biomass in these treatments when compared to unamended soil, which corresponds with the previously reported beneficial effects of manure and organic matter co-application on soil fertility and plant growth [23,60,[67][68][69]. On the other hand, the soil TN content moderately negatively correlated with C:N (r = −0.61).…”

Co-composting of raw manure with other organic sources has recently gained the attention of the scientific community. In the present study, raw manure and manures enriched with humic substances (Humac) or biochar were co-composted to improve their physico-chemical properties. We conducted an experiment including variants consisting of soil amended with manure (M), manure + Humac (M + H), manure + biochar (M + B), and unamended (control). Soil physico-chemical, biological, and plant properties were assessed altogether. All matured manures differed from each other physico-chemically (nutrient content) and in microbial composition, and hence their effects on the observed parameters. Compared to control, the soil respiration and enzyme activities related to N and P mineralization were enhanced due to the amendment of either manure or enriched manures. The M + H treatment resulted in higher pH of the manures as compared to other treatments, whereas the M + B and M treatments revealed the highest Corg contents of the final product, which was negatively correlated with HA:FA. In the same manner, M + H and M + B were the most prominent treatments, causing higher variations in basal soil respiration. The same treatments resulted in the highest percent increase values of soil enzymes related to C, N, and P, which further show the potential of manure modification as a viable option to boost soil fertility and health.

“…As for different UHAs fertilizer formulations, the wheat fed with UHAs0.5 showed a higher grain yield than that treated with other UHAs, while UHAs0.2 and UHAs2.0 showed weaker positive effects (Figure 3), indicating that the response of wheat grain yield to HAs proportions in UHAs accorded with a parabolic function in this study. This trend is more similar with the concentration-dependent stimulatory effects of HAs on plant growth than the binding amount of nitrogen varied with HAs addition [32,33]. Thus, it seems that the enhanced wheat yield treated with UHAs was more attributed to the stimulation of HAs in UHAs on wheat growth, rather than the retention and slow release of fertilizer-N, while the accurate mechanism could be clarified by intensive study.…”

Humic Acids Incorporated into Urea at Different Proportions Increased Winter Wheat Yield and Optimized Fertilizer-Nitrogen Fate

Humic acids (HAs) incorporated into urea fertilizers are highly effective at increasing yield and decreasing fertilizer-derived nitrogen (N) loss from soil, but reports of the optimal proportion in fertilizers remain widely inconsistent. In this study, we examined the effects of urea enhanced with 0.2–5.0% HAs (UHAs) on the yield, biomass production, N uptake, and N residue in fluvo-aquic soil in winter wheat cultivated over two growing seasons from 2018 to 2020 in the North China Plain. UHAs application significantly enhanced wheat grain yield, aboveground dry biomass, total and fertilizer-derived N uptake by wheat, and residue in soil, while reducing the loss of fertilizer-derived N. Additionally, UHAs treatments increased fertilizer-N residues in soil, especially in the top 30 cm soil layer, which increased with the proportion of added HAs. These positive effects were attributed to a higher spike number under UHAs treatments compared to conventional urea. Clustering analysis of the different treatments showed that 0.2% HAs were more similar to conventional urea, while 0.5% had similar effects to HAs at higher proportions. UHAs application significantly enhanced wheat grain yield, mainly via increasing spike number, and optimized the fertilizer-N fate. Among UHAs treatments, 0.5% HAs showed the highest increase in economic benefit.

“…This was confirmed in recent studies where NH 3 emissions were significantly reduced by brown coal additives (Table 5). Good N retention by brown coal can be also attributed to better N mineralization and inhibition of compost urease activity, resulting in a lower rate of NH 3 production and emission [167]. We argue that the LRC-based technologies can be especially effectively used in the processing of livestock and poultry manure to reduce environmental impacts and improve efficiency.…”

Low-Rank Coal as a Source of Humic Substances for Soil Amendment and Fertility Management

Humic substances (HS), as important environmental components, are essential to soil health and agricultural sustainability. The usage of low-rank coal (LRC) for energy generation has declined considerably due to the growing popularity of renewable energy sources and gas. However, their potential as soil amendment aimed to maintain soil quality and productivity deserves more recognition. LRC, a highly heterogeneous material in nature, contains large quantities of HS and may effectively help to restore the physicochemical, biological, and ecological functionality of soil. Multiple emerging studies support the view that LRC and its derivatives can positively impact the soil microclimate, nutrient status, and organic matter turnover. Moreover, the phytotoxic effects of some pollutants can be reduced by subsequent LRC application. Broad geographical availability, relatively low cost, and good technical applicability of LRC offer the advantage of easy fulfilling soil amendment and conditioner requirements worldwide. This review analyzes and emphasizes the potential of LRC and its numerous forms/combinations for soil amelioration and crop production. A great benefit would be a systematic investment strategy implicating safe utilization and long-term application of LRC for sustainable agricultural production.
