	abstract = {Background and aims To provide insight into
		the patterns of soil organic matter decomposition,
		changes in the quantity of biopolymers and the correlation between them were followed using 2D correlation spectroscopy (2DCOS) FTIR.
		Methods Soil organic matter fractions with diferent vegetation/land use (grass, spruce, oak and arable)
		were examined in a 1-year laboratory incubation. The
		non-protected organic matter fraction was calculated
		in terms of particulate organic matter (POM), the carbon stabilized in aggregates as S+A (sand+aggregates), and the mineral-associated organic matter
		(MAOM) as the s+c (silt and clay) fraction.
		Results Forest soils (spruce, oak) exhibited high C
		and N accumulation in the POM fraction (48, 43%
		and 29, 22% for spruce and oak, respectively) due
		to the limited decomposition, caused by low pH and
		high soil C/N ratio. The 2DCOS analysis revealed
		that carbohydrate-protein and carbohydrate-lignin
		correlations could be observed most frequently during
		incubation. The carbohydrate-protein correlation was
		negative in all cases, for all fractions and for all vegetation types, which suggests biogeochemical linkage
		between these biopolymers. The temporal order of the
		spectral changes was widely varied for the vegetation
		types and especially for the SOM fractions. Lipid/
		Lignin → Carbohydrate or Lipid → Lignin/Carboxyl/
		Protein sequences were found for the protected carbon pools (S+A and s+c), possibly because of the
		readily available abundant N compounds present in
		MAOM.
		Conclusion Although lipids and lignin are considered as chemically stable materials that commonly
		remain constant during decomposition, these compounds were found to be very susceptible in all the
		fractions.},

A field experiment with spring oat (Avena sativa L.) was carried out on loamy soil in Debrecen, Hungary, using a small-plot design. Ammonium nitrate was broadcast at rates of 0, 30, 60, and 90 kg N/ha in three replicates. The total N content of the plant, sap nitrate content, and SPAD values were measured at jointing when the first node appeared above the soil surface (Feekes 6) and at boot stage (Feekes 10). Regression analysis between total N content and sap nitrate showed cubic and linear relationships with r2 = 0.7982 (Feekes 6, whole plant) and 0.9625 (Feekes 10, upper developed leaves), respectively. Optimal grain yield was obtained when sap nitrate exceeded 650 mg/L and 540 mg/L at Feekes 6 and Feekes 10, respectively. There were linear and logarithmic relationships between total N content and SPAD values with r2 = 0.8058 and 0.6258 at Feekes 6 and 10. Optimal grain yield occurred over SPAD values of 43 and 48 at Feekes 6 and 10, respectively. Optimal N rate was 60 kg N/ha on the experimental site.},

	abstract = {Protecting humankind’s natural resources and soils, including forestry, represents a top priority in agriculture. Addressing climate change should prioritize preserving and enhancing organic carbon, specifically humus, in soils. In this paper, we examine the impact of soil preparation on soil humus and microbial life during the reforestation of Southern Nyírség, Hungary. We determined soil plasticity, pH in distilled water solution, the quantity and quality of humus content, the total number of bacteria and microbial fungi, as well as CO2 production. In addition to stump removal and plowing, the wealthiest layer of organic matter was detached from the surface. A significant decrease in humus content (HU%) was observed at the five experimental sites (loss of 19.20-40.14 HU% at 0–30 cm depth). Soil organic matter is concentrated in the stump depositions. According to the results, the quantity of humus content is strongly correlated with the measured parameters of soil life, specifically with the number of microbial fungi (r = 0.806 **) and the total number of bacteria (r = 0.648 **). Another correlation (r = 0.607 **) was assessed between the humus content and CO2 production. This study helps to understand the importance of the no-tillage methods used in reforestation.},

	abstract = {Soil microbial communities are crucial for ecosystem services, soil fertility, and the resilience of agroecosystems. This study investigated how long-term (31 years) agronomic practices—tillage, NPK fertilization, and cropping system—along with measured environmental variables influence the microbial biomass and its community composition in Chernozem soil under corn cultivation. The polyfactorial field experiment included three tillage treatments ((moldboard (MT), ripped (RT), strip (ST)), two fertilization regimes (NPK (N: 160; P: 26; K: 74 kg/ha), and unfertilized control) and two cropping systems (corn monoculture and corn–wheat biculture). The soil samples (0–30 cm) were collected in June and September 2023. Microbial biomass and community structure were quantified using phospholipid fatty acid (PLFA) analysis, which allowed the estimation of total microbial biomass and community composition (arbuscular mycorrhizal (AM) fungi, fungi, Gram-negative (GN) and Gram-positive (GP) bacteria, actinomycetes). Our results showed that microbial biomass increased from June to September, rising by 270% in unfertilized plots and by 135% in NPK-fertilized plots, due to higher soil moisture. Reduced tillage, especially ST, promoted significantly higher microbial biomass, with biomass reaching 290% and 182% of that in MT plots in June and September, respectively. MT had a higher ratio of bacteria-to-fungi compared to RT and ST, indicating a greater sensitivity of fungi to disturbance. NPK fertilization lowered soil pH by about one unit (to 4.1–4.8) and reduced microbial biomass—by 2% in June and 48% in September—compared to the control, with the particular suppression of AM fungi. The cropping system had a smaller overall effect on microbial biomass.},
