| Abstract: | The effect of lanthanum (La) accumulation on availability of soil nutrients in red soil was studied through indoor soil culture and pot culture experiments. The results showed that La accumulation decreased the content of soil available nitrogen and phosphorus, that there was significant negative correlation between the concentration of La and soil available nitrogen and phosphorus, and that La had no significant effect on soil available potassium. |
