EFFECTS OF STONEMEAL WITH ORGANIC FERTILIZATION ON TROPICAL SOILS

This paper presents partial results of research whose main goal is to investigate the potential of using rock dust for soil remineralization. Five types of rocks were evaluated (kamafugite, carbonate-bearing mica schist, hydrothermal metamorphic rock, fresh basalt and weathered basalt) with, or without, the addition of organic compost (bovine manure). Experimentation took place near the city of Planaltina, in the Federal District area of Brasilia, Brazil. Testing occurred over a two-year period on five agricultural crops (corn, beans, garlic, carrots and okra), on a minimum of two harvests, using crop rotation. Preliminary results show that different ...
