Carbon-enriched organic amendments diferently afect the soil chemical, biological properties and plant biomass in a cultivation time-dependent manner

Original language description

Background: The farmyard manure application maintains quality of arable soils, provides nutrients, mitigates climate change by soil carbon sequestration. Biochar and other complex carbon rich amendments may stabilize organic matter derived by composting and decelerate organic carbon mineralization. However, how the combined utilization of biochar, humic substances and manure efects on soil chemical and biological properties have been least explored, especially their efect on soil basal and substrate induced respirations are needed to be further explored. Therefore, the potential of biochar and Humac (a commercial humic substances product) in combination with manure to improve the soil properties and plant growth was investigated in this experiment using barley under a short-term (12 weeks) and maize under long-term (following 12 weeks, a total of 24 weeks) cultivation. Results: In the early phase of cultivation (12 weeks) Humac- or biochar-enriched manures (M+H, M+B, respectively) enhanced the contents of nutrient elements (carbon+5.6% and+7%, nitrogen+6.7% and − 5%, sulphur − 7.9% and+18.4%), the activity of enzymes including (β-glucosidase+32% and+9.6%, phosphatase+11% and 6.3%), and dry aboveground biomass (+21% and+32%), compared to the control and manure-treated soil. However, these impacts of M+H and M+B manures were reduced under longer period, i.e., at the experiment end (24 weeks). After 24 weeks of cultivation, a decrease in absolute values of all determined enzyme activities indicated putative reduction of mineralization rate due to presumed higher recalcitrance of manure-derived organic matter, with Humac, biochar amendments. Increased stability of soil organic matter reduced microbial activity due to lower availability of nutrients. Possibly, the shortened period of manure maturation could help preserve a higher amount of less degraded organic matter in the enriched manures to counteract these observed features. Conclusions: We summarized that the biochar and humic substances combined with manure have the potential to improve the soil characteristics, plant biomass and soil health indicators but the improvements faded away in a cultivation time-dependent manner. Further studies are required to explore the structure and functioning of microbial activities under long-term experimental conditions.
