Opis:: Since biochar is considered to be a significant source of carbon, in this work we have evaluated the changes in soil organic matter (SOM) and soil structure due to application of biochar and biochar with N fertilization, and have considered the interrelationships between the SOM parameters and the soil structure. The soil samples were collected from Haplic Luvisol at the locality of Dolná Malanta (Slovakia) during 2017. The field experiment included three rates of biochar application (B0 – no biochar, B10 – biochar at the rate of 10 t ha^-1, B20 – biochar at the rate of 20 t ha^-1) and three levels of N fertilization (N0 – no nitrogen, N160 – nitrogen at the rate of 160 kg ha^-1, N240 – nitrogen at the rate of 240 kg ha^-1). The rate of biochar at 20 t ha^-1 caused an increase in the organic carbon (C_org) content. The combination of both rates of biochar with 160 and 240 kg N ha^-1 also caused an increase in C_org. In the case of B20 the extractability of humic substances carbon (C_HS) was 17.79% lower than at B0. A significant drop was also observed in the values of the extraction of humic acids carbon (C_HA) and fulvic acids carbon (C_FA) after the addition of biochar at a dose of 20 t ha^-1 with 160 kg N ha^-1. However, both rates of biochar had a significant effect at 240 kg N ha^-1. After application of 20 t ha^-1 of biochar the content of water-stable macro-aggregates (WSA_ma) significantly increased compared to control. This rate of biochar also increased the mean weight diameter (MWD_W) and the index of water-stable aggregates (Sw) and decreased the coefficient of vulnerability (Kv). The biochar at a rate of 20 t ha^-1 with 240 kg N ha^-1 the value of MWD_W increased and value of Kv decreased significantly. The contents of C_org and C_L correlated positively with WSA_ma, MWD_W and Sw and negatively with WSA_mi and Kv. The extraction of C_HA and C_FA was in negative relationship with MWD_W. We conclude that the application of biochar and biochar combined with N fertilizer had a positive influence on SOM and soil structure.

Loess landscapes
Opis:: The aim of this article is to establish how land use change influences soil organic matter content in the loess landscape. The research was conducted near Krasnystaw in the Lublin Upland, in forest, on arable land and on abandoned lands at various stages of secondary succession. During the field research, samples were collected from the upper soil layer and analyzed for organic carbon content, fractional composition of humus compounds and soil reaction. The results obtained indicate that the impact of land use change manifests itself in a change of the soil reaction, which turns from neutral or slightly acid into acid. The tillage system reduces organic matter in the soil and increases the humic acids ratio, whereas abandonment of the land causes an evident increase in the soil’s organic matter content and the fulvic acids ratio. These results allow us to state that land use change has a rapid impact on the geochemical properties of the landscape (which can be noticed as soon as 5 years after the land is abandoned).

Opis:: This paper presents an overview of the literature research on the benefits of biocarbon (biochar) as an important part of sustainable agriculture and carbon farming. The main objective was to familiarise the reader with the literature findings on the effects of biocarbon application on the environment, soil, soil organic mater, soil microorganisms, and impact on crop yields. On the basis of the research presented, it can be concluded that the incorporation of biocarbon into the soil generally has a positive effect on soil fertility, but that proper application is required (mainly its application together with fertilization). The quality, properties, and agricultural usefulness of the biochar depend on the raw material that has been subjected to the pyrolysis process, as well as the temperature and time of. The findings of the paper are based on the literature review on the subject.

Opis:: Due to the ease and low cost of implementation, a commonly used method of determining the humus content in soils is the loss-on-ignition (LOI) method. Several regression equations and transformation factors are reported for LOI conversion to soil organic matter (SOM) or total organic carbon (TOC) content. The vast majority of the conversion factors have been developed for surface horizons of lowland soils, while there are only few findings from the mountainous areas. 476 mineral and 79 organic (forest litter) samples from 31 soil profiles located in different altitude zones of the Karkonosze Mountains and under different vegetation were used for analysis. LOI was determined by the drying-weighing method and TOC by the dry combustion method with CO₂ absorption. The average LOI/TOC ratio was about 2, but varied in accordance to LOI value. At the LOI value above 8–10%, the LOI/TOC is maintained at a constant level of 2.0, but with a decreasing LOI it may significantly extend, up to 20 at LOI <1%. In the mountain soils, the best compatibility of TOC determined and estimated based on LOI was obtained when using different conversion factors ( 7.3, 5.0, 3.1 and 2.0) for the four LOI ranges (0–2, 2–4, 4–8, and > 8%, respectively) or when using separate regression equations for LOI of <8 and >8%. Because of huge TOC overestimation by LOI method at LOI values lower than 8–10%, the conversion LOI to TOC is not recommended, unless the direct measurement of TOC content is currently unavailable (e.g. in archival databases).1

Opis:: Soil organic matter (SOM) is considered to be the most important part in the soil. C and N and their forms are most often used to evaluate SOM. In the last decades, C indices have begun to be used to assess soil quality for C changes in SOM due to the different soil management. Since C cycle is closely related to N, there is an assumption that N indices (derived in the same way as C indices) will be sensitive to N changes in SOM under the different soil management. The objective of the study was to evaluate the extent of C and N indices on C and N changes in SOM (in Rendzic Leptosol) under the different soil management practices (1. G: grass and no fertilization – as control; 2. T: tillage; 3. T+FYM: tillage + farmyard manure; 4. G+NPK3: grass + NPK 125–50–185 kg ha-1; 5. G+NPK1: grass + NPK 100–30–120 kg ha-1) in a productive vineyard (Nitra-Dražovce; Slovakia) during the period of 13 years. The results showed that the soil organic carbon (SOC) was reduced by 26% compared to G because of intensive cultivation on one hand, but on the other hand, in T + FYM treatment no significant changes in SOC over the 13 years of the experiment were observed. A higher labile carbon (CL) content was in G+NPK3 then follows: G+NPK1 > G > T+FYM > T for topsoil (0-30 cm). In topsoil, carbon lability increased after a higher level of mineral fertilization, while in subsoil (30-60 cm) after intensive cultivation. The values of CPI for topsoil decreased in the following order: G+NPK1 > T+FYM > G+NPK3 > T. Based on CMI values, intensive C changes in the SOM due to the soil management practices were observed in T treatment. The highest accumulation of carbon and decomposable organic matter occurred in G+NPK3. Incorporation of FYM, and both rates of NPK increased values of NMI by 45, 47 and 36% respectively compared to intensive tilled treatment for topsoil. The highest values of the NPI were detected because of farmyard manure application and mineral fertilization at a higher rate (NPK3) for topsoil and because of intensive cultivation between vine rows as well as plowing of FYM for subsoil.

Opis:: Soil organic matter (SOM) is an essential soil constituent. The deficiency of SOM is an essential problem in many regions in Poland. Diversity of organic matter and the environment create varying structures and compositions, and thus differences in properties of humic substances (HS) especially humic acids (HAs). It was found that soil amendment with organic matter resulted in improving of soil and HAs properties compared with non-treatment ones. The results obtained provided the following evidences. With respect to HAs: an increasing content of carboxylic groups in HAs from amended soils; a major content of aromatic ring systems; higher carbon, nitrogen, hydrogen, and sulphur and lower oxygen contents comparing to the control; the addition of straw caused an increase of carbon content in HAs particles and, consequently a decrease of the C:H ratio; higher content of oxygen functional groups compared with non-treated ones. Organic matter from straw is more resistant to fast decomposition as compared to compost and it shows higher long-term sorption capacity. Therefore, straw may be an equivalent to natural sources of SOM in terms of agriculture and ecosystems protection.
W zależności od rodzaju egzogennej materii organicznej (obornik, kompost, słoma) wprowadzonej do gleb wyekstrahowane kwasy huminowe charakteryzowały się różnymi właściwościami. Stwierdzono, że w kwasach huminowych wystąpił wzrost zawartości grup karboksylowych i fenolowych, większy udział struktur aromatycznych. W kwasach huminowych z gleb nawożonych stwierdzono większą zawartość węgla, wodoru, azotu i siarki oraz niższą zawartość tlenu w porównaniu do kwasów huminowych z gleb bez dodatku egzogennej materii organicznej. Dodatek słomy spowodował wzrost zawartości węgla w składzie pierwiastkowym kwasów huminowych a w konsekwencji zmniejszenie stosunku C:H. Materia organiczna ze słomy jest bardziej odporna na szybki rozkład w porównaniu z kompostem.

Opis:: Straw, particularly cereal straw, is a valuable by-product of crop production, which can be used for various purposes, e.g. as livestock feed and bedding or for making fuels, however it should primarily be retained on farmland in order to prevent soil organic matter (SOM) losses and thus to maintain or improve soil quality. The aim of this study was to analyze effects of the frequency of crop residues (straw) incorporation into the soil on the content of soil organic matter and on crop yields. There were the following experimental treatments: SR - straw of all crop in the rotation removed, S1 - straw of one crop per rotation incorporated, S2 - straw of two crops in the rotation incorporated, and S3 - straw of three crops incorporated into the soil (loamy sand). After 21 years of crop rotation with straw removal (SR) the SOM level in the soil slightly decreased to 14.4 g∙kg-1 soil DM, compared to that in 1997 (14.6 g∙kg-1). However, when straw of one crop (rape) per rotation was incorporated (S1) the content of SOM increased to 15.0 g∙kg-1 soil DM, and to 15.6 and 16.0 g∙kg-1 in S2 and S3 treatments, respectively. Straw retention had also a beneficial effect on the content of labile fractions of SOM (hot water extractable C and N). Grain yields and yield components of wheat and triticale, and seed yields of rape in the SR treatment were not significantly different from those obtained in S1, S2 and S3 treatments.

Opis:: The aim of the study has been to define the stocks and the basic properties of soil organic matter in agricultural-used soil sequence located in the former shoreline of disappearing lakes. The study area is located in the catchment of the Sumowskie Lakes, the Brodnica Lake District, North-Eastern Poland. The investigations involved preparation of five soil pits located in the south-western part of the former Sumowskie Lake bottom and on the southern slope of the adjacent kame hill. The greatest soil transformation is reflected in the quality and quantity of the soil organic matter. Indexes of organic matter quality and TOC stocks are significantly changing along the studied transect. The strongly humidified organic matter is found in mursh horizons. Gyttja layers above the groundwater level have a medium humification index. Horizons saturated with water are very low humidified. TOC stocks drop along the analysed soil sequence from the biogenic plain to the top of the kame hill.
Celem badań było określenie zasobów i podstawowych właściwości materii organicznej sekwencji rolniczo użytkowanych gleb dawnej strefy brzegowej zanikających jezior. Obszar badań był zlokalizowany w zlewni jezior Sumowskich na Pojezierzu Brodnickim w Polsce północno-wschodniej. Analizowano transekt składający się z pięciu profili glebowych znajdujących się w pd.-zach. części dawnego Jeziora Sumowskiego. Obejmował on dno dawnego jeziora oraz przylegające wzgórze kemowe. Największe zróżnicowanie gleb dotyczyło ilości i jakości glebowej materii organicznej. Zarówno właściwości materii organicznej, jak i jej zasoby wyraźnie różnicują się w analizowanym transekcie. Materia organiczna poziomów murszowych gleb pojeziornych odznacza się najwyższym stopniem humifikacji, warstwy gytii, powyżej poziomu wód gruntowych, pośrednim, a poziomy nasycone wodą najniższym spośród analizowanych. Zasoby węgla organicznego zmniejszają się wzdłuż transektu od gleb pojeziornych do szczytu pagórka kemowego (pararędziny).

Opis:: In Morocco, and particularly in the Doukkala irrigated perimeter, sugar beet rot caused by Sclerotium rolfsii is a major limiting factor for the productivity of this crop. The objective of this study was to identify the relationship between the frequency of Sclerotium rolfsii infestation and the quantity of viable sclerotia in the soil on the one hand, and with the different physicochemical parameters of the soil in cropped sugar beet fields on the other hand. In total, 1794 soil samples were collected during a four years period in the whole irrigated perimeter. These samples were analyzed for their sclerotial content. In addition, laboratory analysis of physico-chemical parameters was performed for 94 sugar beet fields in 2019. The study showed that the relative frequency of infestation by Sclerotium rolfsii and the number of viable sclerotia oscillate inversely and present a relative frequency of 45.7, 57.3, 42.3 and 49.5% for 2016, 2017, 2018, and 2019, respectively, and a number of sclerotia of 2.01, 1.65, 2.11 and 1.25 in 250 g of soil for 2016, 2017, 2018 and 2019, respectively. The study showed that the number of viable sclerotia was positively correlated with clay and silt content, soil pH, Mg, K, Fe, Cu, and Mn and negatively correlated with sand, SOM, EC, CaCO3, Zn, B, Ca, NH4 and NO3 contents. The observed decrease in viable sclerotia between 2016 and 2019 can be attributed to the decrease of Fe and Cu in the soil. It is possible that SOM intervenes with its humified fraction in the neutralization of the redox potential of Feand Cu which are involved in the production of sclerotia under oxidative stress. The good control of fertilization, especially organic, allows limiting the production of sclerotia of Sclerotium rolfsii. Data analysis allowed obtaining a significant prediction model of the number of viable sclerotia in the soil according to the physicochemical soil parameters with (R2 = 0.95 at P<0.0001) for only infested fields and (R2 = 0.87 at P<0.0001) for all the fields.

Opis:: Since tillage technologies considerably influence soil properties and have a major impact on soil sustainability, the objective of this study was to evaluate the effects of conventional (CT) and reduced (RT) tillage on basic soil chemical properties at selected Slovak agricultural farms. Subsequently, the relationships between the chemical properties and soil organic matter (SOM) in both tillage technologies were ascertained. Differences in soil properties between long-term RT and CT were investigated at the adjacent plots on thirteen sites, where six soil pits were excavated on each RT and CT plots. Soil samples were collected from all pits, for each 0.1 m layers from the depth of 0.0-0.4 m. The results revealed that the regular overturn of topsoil, and thus the transfer of leached base cations to the surface layer, as well as deeper incorporation of crop residues and fertilizers in the soil cultivated conventionally has been manifested by higher values of pH, lower hydrolytic acidity (H) and the almost uniform content of base cations (mainly in the layer 0.0-0.3 m) compared to the soil cultivated by RT. Apart from H,, none of the examined sorption properties and pH differed significantly between the compared tillage technologies. Therefore, H can be considered as an important indicator of the change of basic chemical soil characteristics. While in RT, there was a significant correlation only between labile SOM fractions and basic soil chemical properties, in CT the sorption parameters and pH were influenced by labile and also stable SOM.
