In particular applying MMC increased the yield of rice in the alluvial soil of the Red River Delta in Gia Lam Hanoi by ton ha and in degraded soil in Hiep Hoa Bac Giang province by ton ha. MMC also contributes to soil reclamation improves soil fertility and increases the micro-organism population in areas. However MMC showed a higher effect on rice that was planted in degraded soil in Hiep Hoa compared to alluvial soil in Gia Lam.

INTRODUCTION In the world products of microorganic compost have been increasingly used as fertilizer for crops since the begining of the XX century. In Vietnam microorganic compost had been studied since 1960s. However it was only paid attention by the central government from 1984 with a research project No. 52D-01-04. The subsequent projects Were KC 08-01 KC 08-20 KHcN 02-06 A B KC 04-04. Beside these there were a number of ministerial level projects such as project No. B99-32-46 No. B2001-32-09 and No. B2003-32-66. Thus several new microorganic composts that applied to agriculture were found. Those composts significantly contribute to improvement of agricultural productivity and sustainability in Vietnam. This paper presents the effects of MMC on paddy rice planting in alluvial and degraded soil during the two-year experiment 2006-2007 . 2. MATERIALS AND METHODS The experiment .
