Abstract Since understanding soil organic matter (SOM) content and quality is very important, in the present study we evaluated parameters of SOM including: carbon lability (LC), lability index (LI), carbon pool index (CPI) and carbon management index (CMI) in the soil as well as in the water-stable aggregates (WSA) under different soil management practices in a commercial vineyard (established on Rendzic Leptosol in the Nitra viticulture area, Slovakia). Soil samples were taken in spring during the years 2008–2015 from the following treatments: G (grass, control), T (tillage and intensive cultivation), T+FYM (tillage + farmyard manure), G+NPK3 (grass + 3rd intensity of fertilisation for vineyards), and G+NPK1 (grass + 1st intensity of fertilisation for vineyards). The highest LI values in soil were found for the G+NPK3 and T+FYM fertilised treatments and the lowest for the unfertilised intensively tilled treatments. The CPI in the soil increased as follows: T < G+NPK3 < T+FYM < G+NPK1. The highest accumulation of carbon as well as decomposable organic matter occurred in G+NPK1 compared to other fertilised treatments, while intensive tillage caused a decrease. On average, the values of LI in WSA increased in the sequence G+NPK1 < T+FYM < G+NPK3 < T. Our results showed that the greatest SOM vulnerability to degradation was observed in the WSA under T treatment, and the greatest values of CPI in WSA were detected as a result of fertiliser application in 3rd intensity for vineyards and farmyard manure application.

With one-year-old Tephrosia candida trees as experimental material, influence of stand density on soil nutrient content and enzyme activity was studied. The results showed that density had little influenced on pH value in 2, 4 and 8 trees m2 stands. The contents of soil organic matter, effective nitrogen and effective phosphorus significantly increased in 2 trees m2 stands. The contents of soil organic matter and effective nitrogen significantly increased, whereas total N, total P, total K, effective N, effective P and effective K significantly decreased in 4 trees/m2 stand. Soil organic matter and nutrients except for total P significantly decreased in 8 trees m2 stand. Among the three density stands, the activities of urease, catalase and phosphatase were the lowest in 8 trees m2 stand.

Abstract In this study, the yield and nutrient content of wheat (Triticum aestivum L.) grown in greenhouse conditions and soil microbiological properties were investigated. Inoculating Amycolatopsis strains, including A.magusensis DSM 45510T, A.orientalis DSM 40040T, and A.azurea DSM 43854T was considered. The mixture of wheat straw (WS) was used to increase soil organic matter content by 5%. It was determined that the grain and straw yield of wheat increased significantly (P < 0.001) in inoculation with Amycolatopsis strains in soils without WS. However, inoculation with Amycolatopsis strains in soil with WS significantly decreased grain and straw of wheat yield. Also, it was found that soil microbial biomass and soil basal respiration (SBR) increased in inoculation with Amycolatopsis strains in both soils with and without WS. While it was established that Cmic:Corg ratio of the control group in the soil samples at the end of the harvest was 1.23, infusing with Amycolatopsis strains was observed to be around 2.95–3.31. Moreover, inoculation with Amycolatopsis strains in soils with WS varied between 0.32–0.40. In the same way, it was determined the microbial metabolic quotient (qCO2) was 2.58 in the control group. This meaning was between 5.67–5.82 in infusing with Amycolatopsis strains and 6.04–6.41 in inoculating with Amycolatopsis strains in soils mixed with ground wheat stalk. As a result, it suggested that the yield of wheat could be increased inoculation with A.magusensis, A.orientalis, and A.azurea, from Amycolatopsis strains, in soils with low soil organic matter content and soils that cannot be shown an increment in terms of organic matter content.

The Impact

Soil organic carbon (SOC) is the most often reported attribute and is chosen as the most important indicator of soil quality and agricultural sustainability. In this review, we summarized how cultivation, crop rotation, residue and tillage management, fertilization and monoculture affect soil quality, soil organic matter (SOM) and carbon transformation. The results confirm that SOM is not only a source of carbon but also a sink for carbon sequestration. Cultivation and tillage can reduce soil SOC content and lead to soil deterioration. Tillage practices have a major effect on distribution of C and N, and the rates of organic matter decomposition and N mineralization. Proper adoption of crop rotation can increase or maintain the quantity and quality of soil organic matter, and improve soil chemical and physical properties. Adequate application of fertilizers combined with farmyard manure could increase soil nutrients, and SOC content. Manure or crop residue alone may not be adequate to maintain SOC levels. Crop types influence SOC and soil function in continuous monoculture systems. SOC can be best preserved by rotation with reduced tillage frequency and with additions of chemical fertilizers and manure. Knowledge and assessment of changes (positive or negative) in SOC status with time is still needed to evaluate the impact of different management practices.

Grasslands fertilizing is used for increasing of forage yields and quality and simultaneously for soil fertility maintenance. The aim of this study was to evaluate the effect of mineral fertilizing on basic agrichemical soil characteristics (pH, available nutrients) and soil organic matter at grazing exploitation of grasslands. 60 kg N.ha−1 was applied in the year of experiment establishment and 90 kg N, 30 kg P a 90 kg K ha−1 in each of following four years. Significantly higher pH (+0.17), available P (+48.5%), K (+15.4%) and organic C (+8.8%) content was found at fertilized treatment. pH value varied significantly during experiment period (range 0.6) and correlated inversely with proportion of white clover in first cut (r = −0.499). Although available K in soil was only on satisfactory level (less than good), K concentration in the forage was even from unfertilized plots higher than physiological requirement of plants. Available nutrient content constitutes only small proportion of total nutrient content: 5.1% at P, 2.1% at K, 12.0% at Mg and 39.0% at Ca.

Due to its importance for organic agriculture, one of the most important agricultural production systems, various sources have been proposed to increase soil organic matter content. Vermicompost is one of those sources known as the resistant last form of farmyard manure which is degraded by earthworms. Soil organic matter or humus and their compounds are nutrient sources that increase physical, chemical and biological quality of soil. Humus and humus compounds improve soil physical, chemical and biological quality parameters increasing rhizosphere aeration and water holding capacity, rehabilitating soil structure, providing plant nutrients and constituting natural media for microorganisms with their regulative effects on soil reactions. In this study, the effects of vermicompost on yield and some growth parameters of lettuce were investigated. For this purpose, a random block designed experiment with 5 different applications was conducted in 3 replicates. The applications were control, vermicompost applications of 100 kg, 200 kg and 300 kg per decare and conventional fertilization. According to the results obtained, yield and growth parameters were improved by vermicompost application when compared to control and conventional fertilization. As a result of this study, it was concluded that 300 kg vermicompost/da is a promising application in lettuce production for optimal yield and soil improvement.

Abstract. An optimized spectroscopic method combining quantitative evolved gas analysis via Fourier transform infrared spectroscopy (FTIR-EGA) and qualitative in situ thermal reaction monitoring via diffuse reflectance Fourier transform infrared spectroscopy (in situT DRIFTS) is being proposed to rapidly characterize soil organic matter (SOM) to study its dynamics and stability. A thermal reaction chamber coupled with an infrared gas cell was used to study the pattern of thermal evolution of carbon dioxide (CO2) in order to relate evolved gas to different qualities of soil organic matter (SOM). Soil samples were from three different sites, i.e. (i) the Static Fertilization Experiment, Bad Lauchstädt (Chernozem) from treatments of farmyard manure (FYM), mineral fertilizer (NPK), combination (FYM + NPK) and control without fertilizer inputs, and cropped soils from the (ii) Kraichgau and (iii) Swabian Alb (Cambisols) areas, Southwest Germany. Soils from Kraichgau and Swabian Alb were further fractionated into particulate organic matter (POM), sand and stable aggregates (Sa + A), silt and clay (Si + C), and NaOCl oxidized Si + C (rSOC) to gain OM of different inferred stabilities. Fresh soil samples from the Kraichgau and Swabian Alb were incubated at 20 °C and 50% water holding capacity for 490 days in order to measure soil respiration under controlled conditions. A variable long path length gas cell was used to record the mid-infrared absorbance intensity of carbon dioxide (2400 to 2200 cm−1) being evolved during soil heating from 25 to 700 °C with a heating rate of 68 °C min−1 during an initial ramping time of 10 min and holding time of 10 min. Separately the heating chamber was placed in a diffuse reflectance chamber (DRIFTS) for measuring the mid-infrared absorption of the soil sample during heating. Thermal stability of the bulk soils and fractions was measured via the temperature of maximum CO2 (2400 to 2200 cm−1 evolution (CO2). Results indicated that the FYM + NPK and FYM treatments of the Chernozem soils of Bad Lauchstädt had a lower CO2max as compared to both NPK and CON treatments. On average CO2max in Bad Lauchstädt was much higher (447 °C) as compared to the Kraichgau (392 °C) and Swabian Alb (384 °C) sites. The POM fraction had the highest CO2 (477 °C), while rSOC had a first peak at 265 °C at both sites and a second peak at 392 °C for the Swabian Alb and 482 °C for the Kraichgau. The CO2 was found to increase after 490 day incubation, while the C lost during incubation was derived from the whole temperature range but a relatively higher proportion from 200 to 350 °C. In situT DRIFTS measurements indicated decreases in vibrational intensities in the order of C-OH = unknown C vibration <C-H<–COO/C=C<C=C with increasing temperature, but interpretation of vibrational changes was complicated by changes in the spectra (i.e. overall vibrational intensity increased with temperature increase) of the sample during heating. The relative quality changes and corresponding temperatures shown by the in situT DRIFTS measurements enabled the fitting of four components or peaks to the evolved CO2 thermogram from the FTIR-EGA measurements to have a semi-quantitative measure of the quality of evolved C during the heating experiment, lending more evidence that different qualities of SOM are being evolved at different temperatures from 200 to 700 °C. The CO2 was influenced by long-term farmyard manure input and also by 490 days of laboratory incubation, indicating that this measurement can be an indicator for the relative overall SOM stability. The combination of FTIR-EGA and in situT DRIFTS was shown to be useful for monitoring the rate of thermal decomposition of different soils and SOM fractions which were related to their relative stability. This knowledge was used for a peak fitting procedure for assigning proportions of evolved CO2 to different thermal stability components.
