AbstractThe paper presents the results of a 3-year field experiment designed to evaluate the content of organic carbon in brown soil (Haplic Cambisol Dystric) developed from a light loamy sand under legumes cultivation. Experimental factors were: species of legume crop (colorful-blooming pea(Pisum sativum), chickling vetch(Lathyrus sativus), narrow-leafed lupin(Lupinus angustifolius), methods of legumes tillage (legumes in pure culture and in mixture with naked oats) and mineral N fertilization (0, 30, 60, 90 kg N·ha−1). Cultivation of legumes on sandy soil did not result in an increase of organic carbon content in the soil after harvest as compared to the initial situation, i.e. 7.39 vs. 7.76 g·kg−1dry matter (DM), on average, respectively. However, there was the beneficial effect of this group of plants on soil abundance in organic matter, the manifestation of which was higher content of organic carbon in soils after legume harvest as compared to soils with oats grown (7.21 g·kg−1DM, on average). Among experimental crops, cultivation of pea exerted the most positive action to organic carbon content (7.58 g·kg−1, after harvest, on average), whereas narrow-leaved lupin had the least effect on organic carbon content (7.23 g·kg−1, on average). Pure culture and greater intensity of legume cultivation associated with the use of higher doses of mineral nitrogen caused less reduction in organic carbon content in soils after harvest.

The paper presents the results of over 30-years of field experiment on soil organic carbon accumulation under different crop rotation, manure and mineral N fertilization. The experiment was conducted with two crop rotations: A – recognized as soil exhausting from humus (potatoes, winter wheat, spring barley and corn) and B enriching soil with humus (potatoes, winter wheat, spring barley, and clover with grass mixture). In each crop rotation, five rates of manure – 0, 20, 40, 60 and 80 t/ha and four rates of mineral fertilizers N1, N2, N3 and N4 were applied. At the beginning of the experiment in 1979, the initial organic carbon content amounted to 0.74%, and after 33 years dropped to 0.61% in crop rotation without legumes. On the contrary, in crop rotation with clover – grass mixture, the tendency to stabilization of organic carbon quantity in soil was observed with the highest value 0.79% and the lowest one 0.72%. It was found that crop rotation enriching soil with humus produced organic matter ever more than those depleting the soil with humus, regardless of the manure fertilization. Mineral fertilization has modified soil organic carbon content.

To estimate the long-term performance and the optimal ratio of feldspathic sandstone with sandy soil, experiments with different ratios of feldspathic sandstone to sandy soil (0:1, 1:1, 1:2 and 1:5 v/v) was conducted. The physical properties as soil texture, water-stable aggregate (WR0.25) content, and the organic carbon content of the composited soil for 6 years, and corn yield for 9 years were determined. Our results showed that after the addition of feldspathic sandstone: (1) soil texture was notably improved, changing from sand loamy soil (1:2 and 1:5) to sand loam soil (1:1) and silt sand soil (1:1) over planting time; (2) content of water-stable aggregate (WR0.25) significantly increased: WR0.25 of treatments 1:1, 1:2 and 1:5 all increased (by 29.26, 31.47 and 11.56%, respectively) compared with that of treatment 0:1; (3) the organic carbon content of the composited soils increased with time in all treatments. After six years of planting, average organic carbon content in treatments 1:1, 1:2 and 1:5 were 1.64, 1.51 and 1.77 g/kg, respectively, which were higher than that of 0:1 treatment; and (4) among the three ratios, treatment 1:2 (12 984 kg/ha) had the highest corn yield, followed by treatment 1:1 (12 040 kg/ha) and 1:5 (11 301 kg/ha). In conclusion, with a good performance, 1:2 was the best ratio of feldspathic sandstone to sand in improving the sandy soil structure of the Mu Us Desert, China.

Background Land use change significantly alters soil organic carbon content and the microbial community. Therefore, in the present study, the effect of changing cropland to grassland on structural and functional soil microbial diversity was evaluated. The specific aims were (i) to identify the most prominent members of the fungal communities and their relevant ecological guild groups; (ii) to assess changes in the diversity of ammonia-oxidizing archaea; (iii) to determine the relationships between microbial diversity and selected physical and chemical properties. Methods We investigated microbial diversity and activity indicators, bulk density and the water-holding capacity of sandy soil under both cropland and 25-year-old grassland (formerly cropland) in Trzebieszów, in the Podlasie Region, Poland. Microbial diversity was assessed by: the relative abundance of ammonia-oxidizing archaea, fungal community composition and functional diversity. Microbial activity was assessed by soil enzyme (dehydrogenase, β-glucosidase) and respiration tests. Results It was shown that compared to cropland, grassland has a higher soil organic carbon content, microbial biomass, basal respiration, rate of enzyme activity, richness and diversity of the microbial community, water holding capacity and the structure of the fungal and ammonia-oxidizing archaea communities was also altered. The implications of these results for soil quality and soil health are also discussed. The results suggest that grassland can have a significant phytosanitary capacity with regard to ecosystem services, due to the prominent presence of beneficial and antagonistic microbes. Moreover, the results also suggest that grassland use may improve the status of soil organic carbon and nitrogen dynamics, thereby increasing the relative abundance of fungi and ammonia-oxidizing archaea.

Four-year investigations conducted as a field experiment aimed to determine the effect of organic fertilisation with farmyard manure, tannery sludge and vermicompost obtained from it on soil humus compounds composition. Equal to farmyard manure effect of vermicompost on organic carbon and total nitrogen was determined in the discussed experiment. Organic carbon content diminished as a result of mineral treatment and fertilisation with untreated sludge. The number of most mobile humus fractions decreased in result of applied fertilisation where as the share of humus compounds not undergoing hydrolysis increased.
