“…According to our results, soil physical properties including SAW, aggregates, and porosity are also affected by O3, manure, and plantation, affecting the absorption, release, and movement of elements in the soil [ 7 ]. Manure can improve the colloidal properties of the soil, because it acts as an organic phase [ 45 ]. Ozone not only increases the rate of chemical oxidation in the soil, by enhancing oxygen (O 2 ) concentration [ 51 ], it can also accelerate the rate of biochemical oxidation by increasing the respiration of plants and soil organisms.…”

“…This is interesting because an oxidizing molecule such as ozone can alter pH; however, the important reason for the non-significant changes of soil pH in the presented experiment can be due to soil bufferic capacity, which increases in the presence of plant and manure. This can be a favorable characteristic of ozone and manure, for plant growth, because pH fluctuations may not positively affect plant growth [33,45].…”

More has to be investigated on the use of ozonated water (O3) for the improvement of growth medium properties. Accordingly, the objective was to examine the effects of O3 (control, 0.5, 1.0, and 2.0 mg L− 1 ) on soil physicochemical (colloidal) properties using organic fertilization (manure), under non-planted or planted conditions. Different soil physicochemical (colloidal) properties including soil available water (SAW), aggregate stability, soil porosity, pH, salinity (EC), organic carbon (SOC), CaCO 3 , and cation exchange capacity (CEC) were determined. The experimental treatments and their interactions significantly (P ≤ 0.05) affected soil physicochemical properties including SAW (4.17-10.98%), aggregate stability and porosity (7.77-57.37%), SOC (0.15-2.09%), and CEC (17.68-42.75 Cmol( +)/kg). Interestingly, the single use of O3 or in combination with manure significantly decreased EC. Although O3 significantly decreased SOC in non-planted soils, it significantly increased SOC in planted soils. O3 may enhance soil physicochemical (colloidal) properties, and if combined with manure in a planted soil, such positive effects may be further enhanced.

“…Results showed that organic fertilization had a positive effect on beetroot P content. Organic fertilization increases the availability of phosphorus in soil [34] as during the mineralization process a certain amount of P is released from organic compounds [35]. The highest beetroot P content was determined for the treatment with stable manure, and was more pronounced in the year with less precipitation (2003).…”

In modern agriculture, besides providing high and stable yields, it is imperative to produce products with a high nutritive quality. The goal of this study was to determine the effect of different fertilization regimes on the macro- and micronutrients in beetroot. A 3-year field trial was set up according to a Latin square method with four types of fertilization (unfertilized control, 50 t stable manure ha −1 , and 500 and 1,000 kg NPK 5-20-30 ha −1 ). The mineral content was determined as follows (mg 100 g −1 in fresh weight of beetroot): 14–29 P, 189–354 K, 18–34 Ca, 17–44 Mg, 0.67–1.83 Fe, 0.41–0.65 Mn and 0.28–0.44 Zn. The highest beetroot P content was determined for the treatment with stable manure, especially in a year with dry climatic conditions. The highest beetroot K content was determined for the treatment with 1,000 kg NPK 5-20-30 ha −1 , but at the same time for the same treatment, a general decreasing trend of micronutrient content was determined, due to the possible antagonistic effect of added potassium. For better mineral status of beetroot, application of combined mineral and organic fertilizers supplemented with additional foliar application of micronutrients can be suggested.

“…It is because the process of pyrolysis significantly increases the degradation rate of organic matter in BI, and as a result, the present N and C can be more easily used by plants and microbes. Similarly, Sun et al [50] found that although the effects of manure were more pronounced on soil properties such as microbial abundance and diversity, WS was also able to increase bacterial population, but not diversity, by increasing soil pH and the availability of different soil nutrients including C, N, and P [44]. Similar to our results, Pokharel et al [38], conducting a global meta-analysis, found that biochar can significantly increase soil microbial biomass C and enzymatic activities.…”

Indicating how different sources of organic matter (OM) may affect the properties of a wide range of soil types, at varying soil moisture (SM), is of significance in the agricultural fields. A large dataset of soil samples (0–30 cm) was collected from different parts of Iran (21 different agricultural regions, with a wide range of physical, chemical, and biological properties) to determine the effects of OM and varying SM on soil chemical (pH, salinity, and organic carbon) and biological (microbial biomass carbon, MBC) properties. The collected soil samples were incubated (9-month period) with the experimental treatments including OM (control (M1), 2% wheat straw (WS) (M2), and 2% biochar (BI) (M3)), at different SM levels (0.2 field capacity, FC (V1), 0.7 variable FC (V2), 0.7 constant FC (V3), and saturated moisture (V4)). Wheat straw was pyrolyzed (at 500°C) to produce BI, and their chemical properties were determined. BI salinity (3.1 dS/m) was significantly higher than WS (2.8 dS/m). The organic treatments, especially BI, significantly increased soil OM and MBC compared with the control treatment. The two sources of organic fertilization increased soil pH, OM, and MBC, though such effects were functions of varying soil moisture (drying and rewetting cycles). Due to higher C percentage (61%), the effects of BI, significantly affected by soil moisture, were more pronounced on soil parameters. The tested sources of organic matter (WS and BI), acting as functions of soil moisture, can strongly affect soil chemical and biological properties and contribute to higher efficiency of agricultural fields.
