11. Summary of the new findings of the thesis

- Identified efficiency of agricultural land use in Sonla Province   

- Identified agricultural land quality in Sonla Province

- Identified the limiting factor in agricultural soils for crop yields in Son La Province

- Completed 03 experimental models (maize, coffee, sugar cane) to overcome the limiting factor in the agricultural soils in Sonla Province

- Proposed solutions to overcome the limiting factors and improving efficiency of agricultural land use in Son La Province

12. Paratical applicability, if any:

The results of thesis are important bases for managers and policymakers to make rational decisions which both be sure crop yields, improve fertility soil and increasing soil production ability.

13. Further research directions, if any

- Research on measures rational land use and improve the fertility of degraded soils;

- Research on the model of effective land use, soil improvement and environmental protection.
