“…Feedstocks and biochars were ground in a laboratory mill (mesh size of 1 mm) and dry matter content was determined after drying these materials at 105°C for 12 h (Jindo et al, 2012). In order to determine the total content of macroelements and trace elements, organic material samples were placed in Teflon vessels and treated with 6 cm 3 of concentrated HNO 3 (Suprapur 65%) and 2 cm 3 of H 2 O 2 .…”

The variety of technological conditions and raw materials from which biochar is produced is the reason why its soil application may have different effects on soil properties and plant growth. The aim of this study was to evaluate the effect of the addition of wheat straw andMiscanthus giganteusstraw (5 t DM ha−1) and biochar obtained from this materials in doses of 2.25 and 5 t DM ha−1on soil enzymatic activity, soil ecotoxicity, and plant yield (perennial grass mixture with red clover). The research was carried out under field conditions on soil with the granulometric composition of loamy sand. No significant effect of biochar amendment on soil enzymatic activity was observed. The biochar-amended soil was toxic toVibrio fischeriand exhibited low toxicity toHeterocypris incongruens. Application of wheat straw biochar andM. giganteusstraw biochar in a dose of 5 t DM ha−1contributed to an increase in plant biomass production by 2 and 14%, respectively, compared to the soil with mineral fertilisation. Biochars had a more adverse effect on soil enzymatic activity and soil ecotoxicity toH. incongruensandV. fischerithan non-converted wheat straw andM. giganteusstraw, but significantly increased the grass crop yield.

“…A number of previous studies highlighted the role of phenolic SOM in the regulation of soil enzymatic activities [36][37][38]. Jindo et al [39] reported the up-regulation of phosphatase and other enzymes in biochar-blended composts, concomitantly to increases in lignin polyphenol oxidation. Accordingly, Grandy et al [37] and Leinweber et al [38] found that strong predictive character of oxidation and the depletion rates of plant-derived lignins on the intensity of microbial transformations occurred both in less degraded systems, such as forest ecosystems, as well as in secular cropped lands.…”

Background: The use of compost may relieve the factors that limit productivity in intensive agricultural systems, such as soil organic matter depletion and soil sickness. Concomitantly, the practice of on-farm composting allows the recycle of cropping green residues into new productive processes. Results: We produced four vegetable composts by using tomato biomass residues in an on-farm composting plant. The tomato-based composts were assessed for their chemical, microbiological properties, and their effects on soils and plants were evaluated after their application within a tomato cropping system. Compost characteristics affected plant development and productivity through increased nutrient uptake and biostimulation functions. Soil biological activities, including basal respiration, fluorescein diacetate hydrolysis, β-glucosidase, dehydrogenase, alkaline phosphatase, arylsulphatase, and Biolog community levels of physiological profiles, were differently affected by the on-farm tomato-based composts.

“…The increased activity of β-glucosidase and FDA hydrolysis could be either due to stimulation of a specialized subset of the microbial community by the biochar or growth of biomass in response to initially labile C (Kolb et al 2009, Bailey et al 2011, Qayyum et al 2014. The increase in alkali phosphatase activity by biochar amendment could have been due to a chemical enhancement of enzyme function caused by the interaction with biochar (Jindo et al 2012). In our study, the addition of biochar reduced protease activity in soil, which may be due to a decreased availability of inorganic N (Chintala et al 2014).…”

Biochar added to soil can improve crop growth and productivity. However, the mechanisms of crop growth improvement by biochar application are not well understood, particularly in the presence of soil-borne pathogens caused by continuous monocropping. Thus, a two-year field experiment was carried out to study the chemical and microbiological response of Lixisols (pH 5.8) to the amendment of biochar and its effect on watermelon productivity and Fusarium wilt disease incidence. Biochar was added alone or together with compost before watermelon transplanting. Mixed application of biochar with compost significantly increased watermelon yield as compared to adding compost or biochar alone. However, biochar had no effects on Fusarium wilt disease incidence in both years. Combined application of biochar with compost significantly increased contents of soil NH4+-N, available phosphorus (P) and available potassium (K). Soil Biolog data indicated that the Shannon-Weaver diversity index and evenness index were increased significantly in the combined application of biochar with the compost treatment. There was a significant positive correlation between watermelon yield and soil NH4+-N, available P, available K, microbial diversity or microbial evenness in the continuous watermelon monocropping system.
