“…The estimated order in the increase of CO 2 -C evolution after adding organic amendments to soils (artificial soil mixtures; Fig. 1) confirms literature data about the amendment-specific biodegradability in soils (charcoal < farmyard manure < sheep faeces < straw) (Atkinson et al, 2010;Guenet et al, 2010;Grunwald et al, 2016;Hansen et al, 2016;Sarma et al, 2017;Teutscherova et al, 2017;Li et al, 2018a). Aside from mineralization during incubation, the added organic amendments increased the OC content in soils (Tab.…”

“…Charcoal as an example for black carbon is distinguished from other organic amendments by higher thermal stability (Leifeld, 2007;Plante et al, 2009;Cimò et al, 2014) and low biological degradability (Atkinson et al, 2010;Cayuela et al, 2014;Grunwald et al, 2016;Sarma et al, 2017).…”

“…The biological transformation of organic amendments applied to soils is regulated by their chemical composition (Johnson et al, 2007), physical structure (Prescott, 2010), soil texture and quantity as well. They can consist of easily biodegradable or stabilized organic carbon or both (Sarma et al, 2017). For example, straw as a biodegradable organic amendment is decomposed relatively rapidly by microorganisms which is reflected in high degradation rates (Powlson et al, 2011;Hansen et al, 2016).…”

Sustainable agricultural land use requires an assessment of degradable soil organic matter (SOM) because of its key function for soil fertility and plant nutrition. Such an assessment for practical land use should consider transformation processes of SOM and its sources of different origin. In this study, we combined a 120‐day incubation experiment with thermal decay dynamics of agricultural soils altered by added organic amendments. The aim was to determine the abilities and limits of thermal analysis as a rapid approach revealing differences in the degradability of SOM. The carried out experiments based on two independent sampling sets. The first sample set consisted of soil samples taken from non‐fertilized plots of three German long‐term agricultural field experiments (LTAEs), then artificially mixed with straw, farmyard manure, sheep faeces, and charcoal equal to 60 Mg ha−1 under laboratory conditions. The second sample set based on soil samples of different treatments (e.g., crop type, fertilization, cultivation) in LTAEs at Bad Lauchstädt and Müncheberg, Germany. Before and after the incubation experiment, thermal mass losses (TML) at selected temperatures were determined by thermogravimetry indicating the degradability of organic amendments mixed in soils. The results confirmed different microbial degradability of organic amendments and SOM under laboratory conditions. Thermal decay dynamics revealed incubation‐induced changes in the artificial soil mixtures primarily at TML around 300°C in the case of applied straw and sheep faeces, whereas farmyard manure showed mainly changes in TML around 450°C. Charcoal did not show significant degradation during incubation, which was confirmed by TML. Detailed analyses of the artificial soil mixtures revealed close correlations between CO2‐C evolution during incubation and changes in TML at 300°C with R2 > 0.96. Results of the soils from LTAEs showed similar incubation‐induced changes in thermal decay dynamics for fresh plant residues and farmyard manure. We conclude that the practical assessment of SOM could be facilitated by thermal decay dynamics if modified sample preparation and evaluation algorithms are used beyond traditional peak analysis.

“…In soils, the majority of nitrogen present in complex organic forms which needs to be converted to simpler form prior to plant uptake. Application of biochar changes the soil pH, which favors the autotrophic nitrifying bacteria and ultimately influences the nitrogen transformations in soil [79,80]. Biochar may also act as a habitat for soil microorganisms involving nitrogen, phosphorus, or sulfur transformations [81].…”

The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties are discussed using the existing knowledge. The positive effects of biochar are soil quality depended and change with varying geographical locations. Therefore, long-term field trials examining a range of biochars, soils, and forest types are required for a better understanding of this issue. Careful planning to match biochar with the soil properties is essential to obtain maximum benefits of biochar as a soil amendment.

“…Similar respuesta se obtuvo cuando los tratamientos anteriormente relacionados como enmiendas simples, se mezclaron con roca fosfórica y materia orgánica (gallinaza) en la relación porcentual 75:10:15 respectivamente (T9, T10, T11, T12, T13). Al respecto, Sarma et al (2017) encontraron que la adición de biochar o carbón vegetal empleado como enmienda en agricultura de suelos ácidos, podría ser una opción sustentable para aumentar la productividad de estos suelos.…”

Los Oxisoles comprenden una de las fronteras agrícolas más extensas del mundo; en América del Sur existen 243 millones de hectáreas, 17 corresponden a Colombia. La acidez debida al aluminio, la desbasificación y la baja disponibilidad de fósforo, constituyen los indicadores de infertilidad química más relevantes en estos suelos. El objetivo del presente trabajo, fue evaluar el efecto de materiales de encalado sobre la acidez y el mejoramiento químico de bases en un oxisol típico de sabana nativa, ubicado en la Altillanura Colombiana. Mediante un diseño experimental completamente aleatorio se definieron 13 tratamientos de incubación con tres replicaciones. Se tuvo en cuenta la caracterización química del suelo problema, al cual se incorporó 1.5t.ha-1CaCO3 equivalente utilizando diferentes materiales de encalado comerciales de EQCaCO3 conocido. A los 40 días post-incubación se evaluaron variables químicas relacionadas con la problemática de acidez (pH y concentraciones de Ca2+, Mg2+ y P). Se comprobó que los materiales encalantes usados como enmiendas simples (dolomitas calcinadas, dolomitas molidas, hidróxidos de calcio y magnesio, escorias básicas y cales vivas) presentarón efecto significativo sobre el control de la acidez y sobre el incremento en la concentración de Ca2+ y Mg2+ coloidal. Similar respuesta se obtuvo cuando los tratamientos relacionados como enmiendas simples, se mezclaron con roca fosfórica y materia orgánica (gallinaza) en relación porcentual 75:10:15respectivamente. Los hidróxidos de calcio y magnesio y las escorias básicas de siderúrgica usadas como enmiendas simples o formando parte de enmiendas complejas, ofrecieron efectos superiores en el control de acidez con respecto al resto de materiales.
