| Abstract: | The fertile purple paddy soils were characterized by a lot of compositemicroaggregates of organic-mineral>0.01 mm in diameter,many non-capi-llary pores or pore space>0.2mm in equivalent vadius,rich nutrient con-tent and powerful activity of urease,neutral phosphatase and sucrase.Themicroaggregates>0.01mm in diameter were of much use in regulatingareation and.maintaining a good physical condition-in soil;small microaggre-gates play an important role in storing, supplying and adjusting nutrientand in the transformation of materials. |
