%X The basaltic soils are an important soil resource that has been overlooked for a long time. It is revealed that these soils have excellent fertility and good quality and can make many crops grow well. There are three types of basaltic soils. They are in different geochemical evolution stages and have great differences in the conditions of exploitation and utilization. Among them the soil with weak weathering has great exploitable potentiality according to contents of many nutritive elements and other factors of fertility. The content of total Fe2O3 reaches 220.75% (n = 23) and the amorphous Fe2O3 amounts to 9.08% (n = 18) in the soils. Consequently, soil structure similar to sand in the surface layer develops obviously and leads to exceptional effects on soil exploitation and utilization. It warrants careful consideration that soils derived from different geological horizons, different rocks properties and different new tectonic movements have significant geochemical variations and influences on the exploitation and utilization. But up to now the extent of the influence is little known.
