The paper presents results of some long-term experiences at the Braila Agricultural Development Research Station, with different mineral and organic fertilizers, as well as through rice cultivation. Through agrochemical analyses of the soil as well as through the analysis of the productions, it was found that the optimization of the fertilization system can be done both by the method and by the time of application, which are factors for increasing the efficiency of the fertilizing elements and the economy of fertilizers. The localized application of a small amount of N23P23 or N13P26K13 kg/ha s.a. fertilizers, the so-called starter fertilization, determined the increase in the efficiency of the use of fertilizers for all fertilizing elements. Thus, for phosphorus at equivalent doses, production increases of up to 18% were achieved, for nitrogen up to 5% and for potassium up to 4%. Also, rice cultivation has proven to be the fastest and most effective method of improving and capitalizing on saline soils, especially under the conditions of climate change.
