ABSTRACT
A new compost derived from three waste: farmyard manure, sewage sludge, and marine algae was achieved. After chemical analysis of the raw materials and the final products resulting from composting, research was conducted to test the compost effect on the maize plants growth in the climate chamber. Have been carried out experimental variants consisting of 4 types of compost, applied in four doses, equivalent to the quantities used for the field application, of 25; 50; 75 and 100 t/ha. By material collected from A horizon of an alluvial soil, two control variants, one unfertilized and the other mineral fertilized, were been realized. The four types of compost consisted of different proportions of wastes, namely: equal parts of three waste, and 50% of each waste accompanied by 25% of the other two. The experience has been stopped when the maize plants have reached the stage of 5-6 leaves. The measurements of height and weight of maize plants, as well as chemical analyzes of composite material from nutrient substrate, and of the aerial part of plants have revealed the fertilizing effect of the composts, especially of those that contain in their composition 50% of an organic waste, and also, generated by the applying them in the highest doses of 75 and 100 t/ha.

Keywords: compost, organic waste, sewage sludge, marine algae
