一看土壤颜色。肥土土色较深,而瘦土土色浅。二看土层深浅。肥土土层一般都大于60cm,而瘦土相对较浅。三看土壤适耕性。肥土土层疏松,易于耕作;瘦土土层黏犁,耕作费力。四看土壤淀浆性及裂纹。肥土不易淀浆,土壤裂纹多而小;瘦土极易淀浆,易板结,土壤裂纹少而大。五看土壤保水能力。水分下渗慢,灌1次水可保持6～7天的为肥土地;不下渗或沿裂纹很快下渗的为瘦土。六看水质。水滑腻、黏脚,日照或脚踩时冒大泡的为肥土;水质清淡无色,水田不起泡,或气泡小而易散的为瘦土。七看夜潮现象。有夜潮,干了又湿,不易晒干晒硬的为肥土;
A look at soil color. Soil darker soil color, while the soil is light earth color. Second, see the depth of soil. Soil and soil are generally greater than 60cm, while the relatively shallow soil. Third, see soil adaptability. Loose soil loosening, easy to cultivate; lean soil plow, farming laborious. Fourth, see soil slurry and cracks. Soil is not easy to slurry soil, soil cracks more small and small; very easy to cast leatland soil, easy to knot, small and large soil cracks. Five to see soil water retention capacity. Moisture infiltration slow, irrigation water can be maintained for 6 to 7 days for the fertile land; no infiltration or rapid infiltration along the crack for the lean soil. Six to see the water quality. Water creamy, sticky feet, sunshine or foot stool bulky for the soil; light and colorless water, paddy fields are not blistering, or bubble small and easy to loose for the lean soil. Seventh look at the phenomenon of night tide. A night tide, dry and wet, not easy to dry the sun for the soil;
