This study was conducted to assess the soil properties and soil nutrient contents in Kham Muon Province, Lao PDR,as a basis to propose improvements and variable crops for cultivation purposes. The results showed that the soil had light soil texture (sandy soil), very acidic soil, no saline, high organic matter (OM: 2.6), high N content (N: 0.4%), high total P (TP: 0.1%), total dissolved P (TDP: 5.9mg/100g soil) was relatively high, total sulfur and total dissolved sulfur were high. However, total potassium, total dissolved potassium, calcium and magnesium exchange, micronutrient contents were low, microorganism in underdeveloped soil and high-density population of nematodes. In order to improve the soil quality, lime should be applied to improve the pH, increase the use of organic fertilizers and mulching to prevent soil erosion. Base on the soil analysis results, the variable grasses and crops use as animal feed or vegetable crops, tuber crops, mangos, dragon fruit, pineapples etc. on this soilare proposed to apply.
