Biyoçar ve kompost kullanarak tuz stresi altındaki toprakların özelliklerinin iyileştirilmesi

There is still a lack of knowledge regarding their effects on saline and sodic soil despite the growing interest in biochar and compost as soil amendments for salinity. We hypothesized that biochar and compost can play a role in the betterment of soil in turn have improved crop yield. A two-month green-house experiment was conducted using wheat as an indicator plant to check the effects of biochar and compost on the soil and yield of the crop. Three kind of soil types were taken these are saline, saline-sodic, and sodic and amendments are biochar, compost, biochar + compost. Thereafter, plants were harvested, and plant yield parameters were recorded while soil samples were collected for further lab soil chemical analysis. It was noted that sodic soil influenced the plant biomass most compared to saline soil. Findings for chemical analysis of soil showed positive result that is OC, Ca, Mg, K has increasing trend where EC and Na had decreased trend for all soil type (Saline, Saline-sodic, Sodic) and all amendments (biochar, compost, compost + biochar) which means these are beneficial for soil. On the other hand Result of chemical analysis for plants showed positive effect for Ca, Mg, K and P where Micronutrients (Cu, Zn, Fe, Mn) exhibited no noticeable improvement for saline soil where it is slight change for saline sodic and moderate for sodic soil for every treatment. Biochar and compost decreased sodium and EC and increased nutrient availability which is good for soil condition. Results suggest biochar, compost, and compost + biochar had remarkable effect on salt-stress.
