“…Higher initial and reapplied rates of biochar, together with a higher rate of N-fertilizer (except B20reap+N1), also significantly increased soil pH (KCl) (p ≤ 0.05) when compared to individual controls. These observations of biochar-induced changes in soil pH due to the addition of amendments are in line with expectations [58]. In our study, the unamended soil pH (KCl) was 5.7, and the biochar-amended soil pH (KCl) was 8.8.…”

Recent findings of changing climate, water scarcity, soil degradation, and greenhouse gas emissions have brought major challenges to sustainable agriculture worldwide. Biochar application to soil proves to be a suitable solution to these problems. Although the literature presents the pros and cons of biochar application, very little information is available on the impact of repeated application. In this study, we evaluate and discuss the effects of initial and reapplied biochar (both in rates of 0, 10, and 20 t ha−1) combined with N fertilization (at doses of 0, 40, and 80 kg ha−1) on soil properties and N2O emission from Haplic Luvisol in the temperate climate zone (Slovakia). Results showed that biochar generally improved the soil properties such as soil pH(KCl) (p ≤ 0.05; from acidic towards moderately acidic), soil organic carbon (p ≤ 0.05; an increase from 4% to over 100%), soil water availability (an increase from 1% to 15%), saturated hydraulic conductivity (an increase from 5% to 95%). The effects were more significant in the following cases: repeated rather than single biochar application, higher rather than lower biochar application rates, and higher rather than lower N fertilization levels. Initial and repeated biochar applications, leading to N2O emissions reduction, can be related to increased soil pH(KCl).

“…There were expected that a finding to be consistent with Iwai et al (2019) and show the addition of compost in soil resulted in physical properties such as bulk density, TP, moisture in soil were improved. However, applied compost decreased bulk density and increased TP, moisture, and aeration but the changes were not significant compared to the control, the exception being the quantity of added organic matter to the soil, a key factor in the quality of organic amendments.…”

“…The addition of compost to the soil has shown to have a more beneficial effect on soil physical properties (Tables 1-3 and Figure 1) compared to farmyard manure. The results of Iwai et al (2019) also showed the beneficial effects of compost in increasing maize growth and the yield of Cassava. Also, the study of Nayak and Mishra (2019) confirmed that farmyard manure, composts, poultry manure and bio-fertilizers in various combinations along with a recommended dose of mineral fertilizers were applied to impacted soils to evaluate their effect on plant biomass.…”

“…The soil structure is influenced by the whole complex of external and internal factors, and there are numerous interactions between them (Idowu, 2003;Bronick & Lal, 2005;Šimanský et al, 2013). Organic matter is very important for maintaining structural stability in soils as well as improving the physical, chemical, and biological properties of soils (Iwai et al, 2019). The quantity and quality of organic matter that affects the physical condition of soils, including the soil structure as is known, can be modified through soil management practices (Šimanský et al, 2013;Iwai et al, 2019;Nayak & Mishra, 2019).…”

The application of organic materials for soil amendment, especially the composed manures, plays important roles in reclaiming and improving the physical health, including the soil structure of degraded soils (Are et al, 2017).…”

Licensed under a Creative Commons Attribution 4.0 International License The use of organic amendments for improving soil properties including soil structure is crucial for sustainable soil management. In this study, two organic materials (1. compost, and 2. farmyard manure) both at a rate of 44 t ha -1 as well as their combination were applied to a Hortic Calcaric Fluvisol (Slovakia) to evaluate the soil physical properties to test the potential of these amendments for soil amelioration under gardening conditions. The results showed that the addition of organic amendments did not have any significant effects on bulk density, total porosity, soil moisture and aeration, but their application influenced the total contents of dry-sieved aggregates as well as water-stable aggregates. The highest content of dry-sieved macro-aggregates was in compost > farmyard manure + compost > farmyard manure > control (unfertilized). The stability of aggregates was higher in compost and farmyard manure + compost treatments than in farmyard manure compared to control. Also, better soil structure stability evaluated by vulnerability coefficient was in farmyard manure + compost and compost than in farmyard manure. The highest contents of soil organic carbon and humic substances were found in the farmyard manure + compost treatment and then compost > farmyard manure > control. In compost, farmyard manure and farmyard manure + compost treatments, cabbage yield increased by 52, 22 and 72%, respectively compared to control treatment. Cabbage yields linear also increased as a result of increasing of soil organic carbon and humic substances.

The quantity and quality of soil organic matter (SOM) depending on many edaphic and environmental factors may change in response to agriculture-related practices. The SOM humification process can be supported by the application of mineral fertilizers, but in the production vineyards, such information is lacking. NPK fertilizer alters the soil quality, and therefore, the aim of this study was to: (1) assess the extent and dynamics of different NPK (control—no fertilization; 1st NPK; and 3rd NPK levels) rates to the soil with grass sward cover in a productive vineyard on changes in SOM, humic substances (HSs), and soil structure, and (2) identify relationships between SOM, HSs, and soil structure. Results showed that the share of humic acids in soil organic carbon decreased only in NPK1 compared to control and NPK3 treatments. The color quotient of humic substance values in NPK1 and NPK3 increased by 4 and 5%, respectively, compared to control. Over a period of 14 years, the content of soil organic carbon increased by 0.71, 0.69, and 0.53 g kg−1 year−1 in the control, NPK1, and NPK3, respectively. The content of HSs increased linearly with slight differences due to NPK application. The vulnerability of the soil structure decreased due to fertilization—more at the higher NPK level. The rate of formed soil crust was decreasing in the following order: control > NPK1 > NPK3. In the control treatment, the relations between SOM, HSs, and soil structure were most abundant and with the greatest significance, while with the increasing level of NPK, these relations lost their significance.
