The effect of biochar and animal manure application on some enzyme activities in soil, CO2 production, content of nutrients, and the growth of tomato plants

In this study, some soil enzymes (dehydrogenase, urease, arylsulfatase and alkaline phosphatase) of tomatoes (Lycopersicum esculentum Mill) plant grown in different doses with biochemical animal fertilization with wide C / N ratio, CO2 formation, microbial biomass, other soil characteristics And to determine some parameters related to the development of tomato plant (height, fresh and dry weight). Trial tomato plants of hazelnut biochar with 3 kg of soil in each pot to be grown 0-5 - 10 - 15 to 20 ton / ha and the matured animal manure 5 to 10 - 20 tons / ha of proportion stirred and 9 repeating including randomized plot design The experimental design It was conducted. Trial implementation issues as well: BK5 + AG5, BK5 + AG10, BK5 + AG10,BK10+ AG5, BK10 + AG10, BK15 + AG5, BK15 + AG10, BK20, is in the form AG20. When complete the development of tomato plants were harvested and plant growth analysis was made concerning.Biochar and anımal manure applıcatıon were found to be statistically significant (p <0.01) due to the increase in soil CO2 production, microbial biomass carbon, dehydrogenase, urease and arylsulfatase enzyme activities. Despite the increase in alkaline phosphatase enzyme activity, it was not statistically significant. The most effective dosages for soil biological analyzes were determined to be those doses BK5 + AG5, BK15 + AG5, BK20 and AG20, which increase the biological properties, while change the parameters.As a result of the experiment, it was observed that the applications of biochar and stall fertilization increased the available macro and micro element contents, mainly nitrogen (N), phosphorus (P) and potassium (K) It has been determined that the plants are growing at the plant height with the dry matter values. It has been determined that the application of plants increases fresh and dry matter values and plant height.
