| Survey and classification of highland rice cultivation areas to indicate acid soil crisis was conducted on altitude 700 meters above sea level. Soil sampling was conducted form 7 districts of Mae Hong Son province are namely Muang, Khun Yuam, Mae La Noi, Mae Sariang, Sop Muey, Pai and Pang Ma Pha in the year 2012-2013. A total of 115 soil samples were consisting of 68 paddies and 47 upland conditions. Soil samples were analysis to find out the soil pH. The result showed that the strongly acid, moderately acid and slightly acid are 39.13, 21.74 and 20.86 percentages, respectively. In other hand, the natural, very strongly acid and extremely acid are 8.7, 7.83 and 1.7 percentages, respectively. However 39 percent of upland soil sample and 38 percent of paddy... |

| Paddy soil in Sing Buri province can be classified into 4 levels as high suitability (soil group 3, 4, 7 and 15), moderately suitability (soil group 21), low suitability (soil group 33) and unsuitability (soil group 38). Moreover, yield production potential of those paddy soils can also be divided into 4 levels as more than 850 kg/rai (R1), 701 - 850 kg/rai (R2), 551 - 700 kg/rai (R3) and less than or equal to 550 kg/rai (R4). Field survey of 547 farmers plantation in Sing Buri province during 2007 - 2009 found that at least five rice varieties, which are PTT1, SPR1, RD31, CNT1 and PSL2 were grown. The common varieties which were PTT1 (90.31%), SPR1 (6.22%) and RD31 (0.91%), respectively were planted by direct seeding method with 25-35 kg/rai seed rate,... |
