“…Site abandonment results in negative changes in the fraction-group composition of humus. We also observed a reduction in the proportion of C HA2 bound to Са 2+ in abandoned sites, probably as a result of the cessation of mineral and organic fertiliser application (Litvinovich & Pavlova 2007;Lapa et al 2011). Mature sites are characterised by an increase of fulvic acids in the humus composition, which can be easily observed in their C HA : C FA ratios in comparison with their arable analogues.…”

Soil aggregate structure and soil organic matter are closely interrelated and commonly considered as key indicators of soil quality. The aim of this study was to evaluate the effects of different fallow durations on indices of soil structure and humus status indicators. Studies were conducted on abandoned agricultural fields (15, 20 and, 35 years after abandonment). As a reference site, we used a cultivated field in the area. The experimental soil fields are classified as Gleyic Cambisols. Soil macroaggregates were separated with the sieve (dry sieve) to seven aggregate size fractions, i.e.> 10, 10–5, 5–2, 2–1, 1–0.5, 0.5–0.25 and < 0.25 mm. The humus status parameters of soils included the following indicators: soil organic carbon (Corg), humus reserves (QH), the degree of humification of organic matter (SOMdh), fractions of humic acids (HA) (free and bound with monovalent cations and Al2O3, Fe2O3, bound with Са2+ which forms humates, bound with clay minerals), fulvic acids (FA) (free aggressive) and ratio of HA to FA (CHA : CFA). After a fallow period of more than 20 years on the surface formation of a sod layer. A long-term fallow period had an impact on the mean weight diameter of the aggregates (MWD) and agronomically valuable aggregates (AVA). Fallow soils have a significantly better structure than soils under a cultivated field. Long-term cultivation leads to the deterioration of soil structure and the formation of large aggregates (>10 mm). The Corg content remains at the level of the background content when the soils are left fallow for less than 15 years and increases over time. The Corg in the upper 0–20 cm soil layer has been shown to increase from 3.55 to 8.74% on arable land that has been fallow for 35 years and has been largely associated with significant accumulation of organic matter within the plant root mass. Mature sites are characterized by an increase of fulvic acids in the humus composition in comparison with their arable analogues. The abandonment of soil agricultural use and the cessation of mechanical tillage results in the restoration of the natural structure of soils and the improvement of their agrophysical properties. Such studies have not been previously conducted in the Primorsky region of the Russian Far East.

“…The mineralization of humus depends on the cultivated agricultural crop, the grain size distribution of the soil and the intensity of its cultivation [12,13]. Therefore, the value of nitrogen yield was corrected by correction factors for humus mineralization depending on the grain size distribution and soil cultivation intensity.…”

The purpose of the study is to determine the influence of mineral and organomineral fertilizer systems on the balance of humus and nutrients in meadow-chernozem soil of the rice ecosystem. The field test was conducted at the Maryano-Cheburgolsky irrigation massif of the Kuban-type rice irrigation system, which studied the effect of mineral fertilizers and their combination with manure slurry introduced in different periods (autumn and spring) and in different ways (with and without the nitrification inhibitor Entec FL). It was established that the optimization of mineral nutrition of plants is accompanied by an increase in rice yield by 2.32–2.78 t/ha and an increase in the removal of nutrients from the soil with harvest. The deficit-free balance of humus and food elements in meadow-chernozem soil under rice is ensured by using an organomineral fertilizer system with slurry application rate of 30 t/ha and N120P80K60 mineral fertilizers. The combined action of mineral and organic fertilizers reduces the loss of humus from the soil by 2.9–3.0 t/ha and returns nitrogen 51.4–61.4 kg/ha (35.1–46.8%), phosphorus – 48.6–55.6 kg/ha (72.1–92.1%), potassium – 20.8–31.4 kg/ha (21.4–52.0%) taken with rice crop.

The article considers the results of many years of field experiment (1968-2018) conducted in the Central part of the Non-Chernozem zone of Russia (Vladimir region). The research was carried out during eleven rotations of the four-field grain crop rotation. The study shows the effect of use of organic and mineral fertilizers applied in various doses and combinations on crop rotation yield, fertility of sod-podzolic sandy loam soil. It was found that the organomineral fertilizer system (manure 10 t/ha + N50P25K60) provided stable crop rotation productivity (on average for eleven rotations) at the level of 39.9 c. e./ha, or 79.7 % higher than the control without fertilizers. The mineral fertilizer system at medium doses of fertilizers (N50P25K60) was at the level of the organomineral system. The organic system was inferior in efficiency to the mineral system, both at medium doses (manure 10 t/ha) and at elevated doses (manure 20 t/ha). At the same time, the long-term use of organic fertilizers provided an increase in the humus content, depending on the dose of litter manure, by 16-36 % compared to the initial values. The use of organic fertilizers led to the stabilization of the content of available forms of potassium in the soil at an average and elevated level, respectively. Stabilization of the content of mobile phosphorus in the soil at the level of average supply was noted in mineral, organomineral and organic fertilizer systems, respectively, with low and medium doses. When using increased doses of fertilizers, there is a further increase in the content of nutrients in the soil. Growing crops in crop rotation without the use of organic and mineral fertilizers gradually led to a decrease in yield. The use of fertilizers provided greater stability of crop yields over the years of the study compared to the variant without fertilizers. The soil in the variants with organic (manure 20 t/ha) and organomineral (manure 10 t/ha + N50P25K60) fertilizer systems was characterized by high values of the main physiological groups of microorganisms. The ratio of the number of amylolytic and proteolytic microorganisms was 1.1-1.2, that indicated a balance in the processes of mineralization of organic matter in the soil and its humification.
