“…This enhances the soil structure to reduce the microbial degradation of organic materials [60]. Among the organic amendment treatments, TL recorded the highest SOC due to the higher lignin and polyphenols contents and higher lignin/N ratios in TL which reduces the rates of decomposition thereby increasing SOC accumulation in the soil [61].

Aims:This research aimed to assess how the physicochemical properties of black soil respond to different organic amendments after 10 years of application. Study Design: The experiment was established in 2010 and followed a randomized block design consisting of 24 plots (5 m × 5 m) 25 m 2 with eight treatments in three replicates. Place and Duration of Study:The study site was located at the Jilin Agricultural University Research Farm, Northeast China (43°48′ N, 125°23′ E; km). Methodology: The treatments for the study included an annual input of chemical fertilizer and organic amendments at the surface of the soil. The treatments were: Control (CK), chicken manure Opoku-Kwanowaa et al.; AJAAR, 12(2): 24-34, 2020; Article no.AJAAR.54606 25 (JM), fodder grass (FG), mushroom (MS), maize straw (MZ), tree leaf (TL), pig manure (PM) and cow manure (CM). Chemical fertilizers were added at the rate of 165 kg of N, 82.5 kg of P and 82.5 kg of K ha_1 per year. Application rates of organic materials were adjusted to similar amounts of organic matter (2000 kgha−1). In June 2019, soil samples were collected from each of the amended fields. In each field, three sampling points were randomly selected. Soil samples were collected from the 0 -20 cm depth using a core sampler then taken to the laboratory for soil physicochemical properties analysis. Results: Comparing the results of the organic treatments with CK, bulk density decreased by 5.6-18.0% while porosity, EC, pH, total N and SOC significantly increased in the organic treatments by 6.0-25.9%, 8.3-25.0%, 0.52-1.7%, 2.7-54.7% and 1.3-18.4% respectively. The textural class of soil under the different treatments did not change however, the distribution of soil particle size varied among the treatments, where high clay and silt content were recorded in the amended fields. Moreover, the application of different organic materials significantly affected the soil aggregate stability and this was attributed to the increase in organic matter content which accelerated important microbial activities in the soil to improve aggregation. At higher suction potentials, higher water contents were recorded in the organic amended fields mainly due to the improved physical properties of the soil. Original Research Article Conclusion:The study results showed that the application of organic amendments greatly improves the physical and chemical properties of black soil. Therefore, using these organic amendments can serve as an effective strategy to enhance soil quality and fertility.

“…Dai et al [11] applied four types of OMs pig manure, biogas residue, biochar, and crop straw separately to soil at the same nitrogen (N) application rate, and concluded that OMs applied to a sandy loam soil shaped the bacterial community of the soil. Hu et al [12] evaluated the variations in the structure of HAs after the application of chicken manure, sheep manure, maize straw, fodder grass or tree leaves in a Chernozem under plastic mulched drip irrigation, and found that the amendment of tree leaves was most effective in increasing the accumulation and structure stability of HAs. The HAs extracted from a soil amended with municipal sewage sludge for seven years had a higher concentration of aliphatic and N-containing groups, but a lower concentration of polysaccharides than those from the unamended soil based on the FTIR spectroscopy [13].…”

The objective of this study was to examine the structure changes in humic acids (HAs) in Chernozem after the application of different types of organic materials (OMs) under an indoor simulation condition for plastic mulched drip irrigation, measured with Fourier transform infrared (FTIR) spectroscopy. The biotechnological extract of fulvic acid (BFA), decomposed sheep manure (M), corn straw pellets (Ps) and corn straw powder (Pr) were used as the four OMs for testing, and they were applied to Chernozem at the same amount of actual material; three nitrogen (N) levels (no N, low N, and high N supply) were applied to each type of (OMs), separately. The total culture period was set to 90 days and soil sampling was taken at 0, 30, 60 and 90 days, respectively. The results showed that different types of OMs exerted different effects on Chernozem based on the FTIR spectra of HAs. The application of M combined with high N supply was the best way to fertilize Chernozem, under which the H-bonded OH groups and aromatic compounds were enhanced, resulting in increased soil carbon (C) sequestration; while the carbohydrates in HAs was easily consumed as microbial energy substance. The HAs from the Chernozem amended with BFA became more aliphatic, simpler and younger. High N supply was beneficial for increasing the complexity of HAs from Chernozem amended with Ps, but was not conducive to soil cation retention. Within a short time of incubation, the application of Pr combined with high N was detrimental to the C sequestration in Chernozem, and inhibited the consumption of carbohydrates by microorganisms.

“…Dai et al applied four types of OMs, including pig manure, biogas residue, biochar and crop stover, to soil at the same N level and concluded that OM amendment shaped the bacterial community in sandy loam soil by changing the soil pH and SOC [5]. Hu et al evaluated the variation in the structure of HAs after the application of chicken manure, sheep manure, maize stover, fodder grass and tree leaves to semiarid soil under plastic mulched drip irrigation and noted that the chernozem amended with tree leaves was the most effective for the accumulation and stability of HAs [6]. Lucas et al reported that HA spectra were not greatly influenced by the maturity of the amendment or by the application dose [7].…”

Returning organic materials to fields is an effective management practice for improving soil quality in agroecosystems. In the case of scarce organic material resources, choosing the optimal material type for improving the quality of a soil type is an urgent problem to be solved. The objective of this study was to evaluate the temporal variations in the spectroscopic characterization of humic acids (HAs) over a period of 90 days after applying biotechnologically extracted fulvic acid (BFA), well-decomposed sheep manure (M), corn stover pellets (Ps) and corn stover powder (Pr) at equal C amount to a chernozem under laboratory conditions, measured by Fourier transform infrared (FTIR) spectroscopy and ultraviolet-visible spectrophotometry (UV–Vis). The results indicated that the BFA and Pr with higher C contents (68.9 and 59.8 g kg−1, respectively) were more beneficial to the C mineralization of HAs. M, applied in the largest amount, together with the highest available N, P, and K contents (575.4, 160.1, 478.9 mg kg−1, respectively), and its more easily consumed carbohydrates as well as well-decomposed status, was more likely to promote the condensation of HAs. BFA carried more hydrophilic groups into the HAs, while Ps did not introduce high levels of adsorbed H2O molecules and aromatic C=C (or C=O) groups. Ps did not affect the molecular structure of HAs after incorporation into the chernozem. At the equal C input amount, M had the greatest benefit, whereas the beneficial effect of Ps was the least, in improving the chernozem quality.
