This experimental work was undertaken to assess the effect of various fertilization regimes (CaNPK, NPK, CaPK, CaPN, CaKN and Ca) and different soil properties on growth and yield of Miscanthus plants and to check the impact of this plant on soil microbial characteristics. Field experiment was set up in 2003 on a long-term fertilization experiment, which had been established since 1923. Miscanthus giganteus response to high soil acidity and deficiency of N, P and K was investigated. Some physico-chemical and microbiological properties of soil samples were estimated and microbial characteristics of soil were conducted to investigate the number of the following microorganisms: heterotrophic bacteria, microscopic fungi, and some diazotrophic bacteria. Obtained results showed that, the highest yield of Miscanthus was obtained from the field fertilized with the CaNPK; while the lowest one was found for plants grown without nitrogen (CaPK). The high acidity of soil and small amount of phosphorus did not affect the yields in the NPK and CaKN combinations as compared with CaNPK one. The experiments showed that Miscanthus giganteus responded positively to mineral fertilization, especially with nitrogen. The rhizosphere of Miscanthus plants provides a suitable environment for the growth and development of microorganisms, in contrast to the non-rhizosphere zone.

Abstract Aims The objectives of this study were to examine the long-term substitution of mineral phosphorus (P) fertilizers with manure (M) plus nitrogen (N) fertilizers and how they affect the forms of P that occur in soil, soil P distribution, and plant growth.Methods We used a solution of 31P nuclear magnetic resonance (31P-NMR) spectroscopy to study the correlations between long-term fertilization regimes and the forms of P that occur at different soil depths. Then we investigated yield, plant growth, and soil properties.Results A 40-year field experiment showed that the use of M + N fertilizers can significantly improve plant growth and yield. The proportion of organic P in the 20-40 cm soil layer was significantly increased by long-term M fertilization. The concentrations of various forms of P (orthophosphate, pyrophosphate, diesters, monoesters, and total inositol hexakisphosphate, IHP) in topsoil increased significantly with the combination of M with N + P mineral fertilization. The addition of M greatly increased the stereoisomers of IHP (myo-IHP, scyllo-IHP, neo-IHP, and D-chiro-IHP) and the proportion and concentration of corrected diesters. There were no significant differences in the pyrophosphate contents of the 40-60 cm soil layer according to fertilization type and year of fertilization. There were also no significant differences in IHP stereoisomers and diesters according to fertilization year. The P forms that contributed to corn yield were orthophosphate, diester, and IHP. Further, pyrophosphate made no significant contribution to corn growth. Conclusions Over the long-term, pig manure can significantly increase the amount of orthophosphate that is directly absorbed by crops and the amount of IHP stereoisomers that can be used by plants. Orthophosphate and IHP are the two key factors that have a positive effect on plant growth.

Soils were sampled from the plots with four variants of fertilisation: Nil – without fertilisation, NPK – mineral fertilisation, FYM – farmyard manure, FYM + NPK – farmyard manure with mineral fertilisation, and two variants of crop rotation: field IV – classical 9-year crop rotation, field B – 2-year rotation of alternative growing. Determination of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity was conducted during the period 1999–2004. The urease activity was positively affected by manure fertilisation (FYM) and by the combination of FYM + NPK. The statistically significantly highest counts of <I>Azotobacter</I> spp. and the highest nitrogenase activity were determined on field B in variants FYM and FYM + NPK. The results show that there was a higher amount of accessible nitrogen present on field IV than on field B. This might explain the lower counts of <I>Azotobacter</I> spp. and therefore the lower nitrogenase activity. According to our results, activity of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity are very closely connected with N inputs.

: In November 2004, forest stands in the Tatra National Park (TANAP) were affected by windthrow and in July 2005, the wildfire broke out on a part of the affected area. The objective of this study is to evaluate the impact of the windthrow and fire disturbances on soil microbial activity. Basal and potential soil respiration, N-mineralisation, catalase activity, soil microbial biomass, and cellulase activity were measured in soil samples taken from the A-horizon (depth of 0–10 cm) along 100 m transects established on 4 plots (reference site, burnt, non-extracted, and extracted sites) in October 2006. Some soil microbial characteristics exhibited a high spatial variability, especially microbial biomass and N-mineralisation. Significant differences in soil microbial characteristics (especially basal soil respiration and catalase activity) between plots were found. Generally, the highest microbial activity was revealed on the plot affected by fire. Soil microbial activity was similar on the extracted and non-extracted sites.

Aim of study: This study evaluated the effect of the application of liquid aerobic treated manure (continuous liquid composting, CLC) on physical, chemical and biological soil properties, with the objective of monitoring changes induced by soil management with CLC as a biofertilizer.Area of study: Colonia, Uruguay (lat. 34,338164 S, long. 57,222630 W).Material and methods: Soil’s chemical properties, including nitrogen mineralization potential (NMP) and 15 microbiological properties (microbial biomass carbon, MBC; mesophylic aerobic bacteria; actinobacteria; filamentus fungi; fluorescein diacetate hydrolysis; dehydrogenase; with NMP; acid and alkaline phosphatase; cellulolose degraders; P-solubilizing bacteria; nitrifying; denitrifying and free-living N-fixing microorganisms; glomalin; and soil-pathogenicity index, SPI) were evaluated in two sites with similar cropping history, with one and three years of respective CLC application.Main results: CLC application had significant effects on soil microbial biomass (p<0.05), soil enzyme (p<0.1) and functional groups activity (p<0.05). SPI decreased in both sites with CLC application. No significant variations were detected for the chemical variables, with the exception of NMP, which was significantly high (p<0.05) in soil treated with CLC at both sites.Research highlights: The improved biological soil properties analyzed (MBC, soil enzyme activities and SPI, together with NMP) emerged as reasonable indicators to assess and monitor the effects of CLC application.

Summary Organic fertilization has been shown to benefit soil biota. A field experiment was established in 1991 at the AGES experimental research station Ritzlhof to investigate the effects of long-term fertilization on soil biota and crop yields. Experimental plots were cultivated using a crop rotation with maize, wheat, barley, and pea. Eight treatments consisted of compost application (urban organic waste, green waste, cattle manure, and sewage sludge compost). Composts were applied exclusively (organic) or amended with mineral nitrogen (N) fertilizers (80 kg N ha−1, organic-mineral) and compared to 0 (control) and mineral (40, 80, and 120 kg N ha−1) fertilization. Earthworm activity and biomass, litter decomposition, crop growth, and yield parameters were investigated under winter barley (Hordeum vulgare L.) in 2014 after uniform mineral fertilization and 1.5 years after the last compost application. Earthworm activity was significantly increased under long-term organic-mineral fertilization compared to the control, whereas earthworm biomass was unaffected by compost application. Litter decomposition rate was highest in the control. Only barley stem growth was affected by fertilization, whereas other barley parameters including yield were unaffected. The results showed that long-term fertilization affects soil biota even if compost is not applied every year.

Abstract. We used differential scanning calorimetry (DSC) to infer thermal properties of soil organic matter (SOM) in the static fertilization experiment in Bad Lauchstädt, Germany, which has been established in 1902. Four treatments (null N, change from null to manuring in 1978 NM, change from manuring to null in 1978 MN, and permanent manure and mineral fertilization since 1902 M) were sampled in 2004. Soil organic carbon contents were highest for M (2.4%), lowest for N (1.7%), and similar for MN and NM (2.2%). DSC thermograms were characterized by three peaks at around 354, 430, and 520°C, which were assigned to as thermally labile and stable SOM and combustion residues from lignite, respectively. DSC peak temperatures were relatively constant among treatments, but peak heights normalized to the organic C content of the soil were significantly different for labile and stable SOM. Labile C was higher for M>MN=NM=N, and stable C decreased in the order N=NM>MN=M, showing that agricultural depletion of SOM increases the share of thermally stable C. Lignite-derived C was not affected by management, suggesting a homogeneous deposition across treatments.

Disposal of untreated olive-mill wastewater (OMW) is a major environmental problem in many Mediterranean countries. This study assessed the impact of OMW application on soil microbiological properties and explored the relationship to soil chemical properties during a 9-month, periodical soil-sampling campaign in a pilot study area in Crete, South Greece. Cases studied involved: direct application of OMW on soil; OMW disposal in active evaporation ponds; sites hosting evaporation ponds that have been inactive for the past 9 years; sites downstream of active evaporation ponds; and control soils, upstream of the waste-disposal ponds. Long-term OMW disposal on land affected the main soil chemical properties. Applicability of the results from the systematic monitoring was confirmed by results obtained in other OMW disposal sites around the pilot area. Soil microbial properties (microbial activity, microbial biomass carbon, and metabolic quotient) were considerably affected by OMW disposal. Moreover, seasonal changes of soil properties revealed short- and long-term residual effects due to OMW disposal. Significant correlations were observed among soil microbial characteristics and soil chemical properties, clearly indicating a close relationship between chemical properties and the transformation of microbial communities in soil after OMW land spreading. The determination of a key set of chemical and microbiological parameters that can be used as indicators for monitoring soil quality at olive-mill waste-disposal areas will verify the efficiency of the techniques used for the land disposal of OMW and will consequently promote their sustainable management.

The Impact

Bio-organic agriculture considers the medium- and long-term impact of agricultural interferences on the agro-ecosystem. It aims to produce food while setting an ecological balance to soil fertility. Bio-organic agriculture takes a proactive design as opposed to treating problems after they emerge, so the study was conducted for studying two factors: First: the cultivars (Riviera and Arizona) class A resulting from cultivation of class E imported and cultivated in spring season 2018. The second factor: fertilizer combinations (bio-organic fertilizers compared with traditional chemical fertilizers). Arizona cultivar significantly achieved the highest values, in most of the study parameters compared to Rivera cultivar. Significant differences were observed between the treatments of fertilizer combinations, the treatment (organic fertilizer + bio-fertilizer + 25% chemical fertilizer) significantly achieved the best values compared to the control. Bi-interaction treatment (Arizona cultivar + organic fertilizer + bio-fertilizer + chemical fertilizer 25%) achieved the highest yield per hectare (43.24 tons.ha−1).

Aim. To determine the regularities of the transformation of quality and quantity composition of humus, its en- ergy intensity at long-term fertilization of soils. Methods. Long-term stationary experiments were conducted on chernozem soils of different granulometric compositions. The analytical work was done in the certifi ed laboratory in accordance with the current normative documents: preliminary treatment of samples for physi- cal and chemical analysis (DSTU ISO 11464); determination of dry substance and humidity by the mass – by the gravimetric method (DSTU ISO 11465). Mass fraction of total carbon was determined by the oxidimetric method (DSTU 4289:2004); humus group composition − by Turin’s method in the modifi cation of Ponomario- va and Plotnikova (DSTU 7828:2015); low heating value of the soil and organic material − by the calorimetric method using В-08-МА set (DSTU 7866:2015); preparations of humic substances were isolated according to DSTU 7606:2014. Results. Long-term fertilization promotes considerable changes in the quality composition of the whole system of humic substances of chernozems of different granulometric compositions. It also has a different impact on the energy accumulation both in the soil and in humic acids (HA). Conclusions. The new formation of HA in typical heavy loamy chernozem with organic and mineral fertilization systems occurs due to the second and third fractions on the background of the decrease in the fi rst and the most mobile fraction of HA. The mobility degree of the whole system of humic substances under the impact of different fertilization systems does not differ from the control considerably; the tendency towards the increase in this index was observed only for the mineral fertilization system. In the organic and mineral fertilization systems, the new formation of HA in typical weak alkali light loamy chernozem occurs due to the fi rst and second fractions. The aggravation of HA structure and the increase in the degree of condensation was registered only for the organic fertilization system. The level of mobility of the whole system of humic substances in this soil is increased compared to the control under the impact of the organic and mineral fertilization systems. A considerable dif- ference in the indices of energy, present in the soil and HA fractions, isolated from this soil, was determined. The maximal amount of energy is in labile forms of HA – in the range of 10.62−15.85 MJ/kg, the smallest amount – in the fractions, tightly connected to the mineral part of the soil (1.47−4.09 MJ/kg). The amount of energy is in direct relationship to the applied agrotechnical means, which is in good agreement with the data on the impact of different fertilization systems on the humic condition of soils.
