Bio- accessibility increase soil nutrients and other natural sources and increase productive use of nutrients in crops, accompanied by decrease the impact of pollutant chemical fertilization on the environment, are major goals of modern agriculture and organic farming by default. The research carried out in the last years on the unconventional fertilization methods and means puts the problem on some new methods to prevent chemical pollution of vegetal production environment. Globally, application of nutrients in the form of dilute solutions by foliar spraying has become a current practice in many cultures, the absorption and translocation of nutrients from the skin of the plant in different plant organs is an undeniable reality. This paper refers to tomatoes grown, Dacia cultivar, in greenhouse (R.I.S.S.A., Bucharest) by an unconventional fertilization method. Tomato represents a basic product in human food, being consumed under both fresh and canned condition. The great number of bell pepper cultivars and varieties constitutes the raw material for producing a large range of culinary products. In this context the main objectives in research carried out were complex agrochemical testing of ecological liquid compositions approved for use in Romania agriculture, two with effect by incorporation in soil (Neb 26 and Stimusoil) and two with foliar applied on plant (Kelpak and Bionat) and quantifying the effect of fertilization of the fertilizers applied on different topsoils of fertilization. Experimentation was conducted in greenhouse of R.I.S.S.A. Bucharest (2004-2007), experiences were placed in Mitscherlich pots, which were introduced 20 kg soil. According to the testing methodology for each experimental combination of factors has ensured a number of 3 repetitions. The analysis of experimental data obtained can be observed that the tested foliar fertilizers were provided, in most cases examined, provided statistical yield increases compared to unfertilized ecological control.
