4 New conclusions of the thesis:
4.1 New contributions in theory
- Provide new information on the relationship of fertilizer - soil fertility - ecology of reddish brown soil in the Di Linh Plateau
- Supplementing the scientific basis in the strategy of managing balanced and reasonable fertilization between inorganic fertilizers and organic fertilizers, contributing to improving the efficiency
of using inorganic fertilizers and improving fertility of reddish brown soil Sustainable cultivation of coffee
4.2 New contributions to practice
- Provide technicians with efficient and effective use of fertilizers to increase coffee yields, reduce fertilizer costs in lieu of chemical fertilizer misuse and use untreated organic fertilizer for crops Coffee
is causing environmental pollution and low production efficiency
- Contribute some technical solutions to use fertilizer in coffee production in the direction of increasing economic efficiency and improving fertility of reddish brown soil in the strategy of using and protecting the sustainable land resources of the province Lam Dong
4.3 New contributions to the proposed solution
- Determine the importance of nitrogen and phosphorus fertilizer doses and organic fertilizers to the fertility and ecology of the basalt reddish brown soil
- Proposing solutions to use nitrogenous fertilizer, phosphorous and organic processing for high-yielding coffee to stabilize coffee productivity in Lam Dong
