soil depth การใช้

• Maximum concentration of its feeding roots is available up to soil depth.
• Fluctuations in soil temperature are much lower with increasing soil depth.
• Their ideal soil depth conditions are between 60 and 100mm.
• Habitable soil depths can range from 34 to 137 mm.
• Small plants requiring shallow soil depths were chiefly selected.
• Soil depth varies from 15 cm to 50 cm, superimposed on a bed of sand.
• The soil depth varies between 20 and 50 cm and soil erosion is a consistent problem.
• Thus the soil depth, acidity ( pH ) and soil moisture vary continuously along the slope.
• The actual soil depth is typically only about and may contain up to 25 percent cobblestones.
• The sixteen acacia species vary over this range, their distribution determined by edaphic conditions and soil depth.
• Soil depths around the summit are thin.
• Seeds germinate best at about 1 inch soil depth in shady areas in the spring following fire scarification.
• Soil depth should be more than 100 centimeters for mineral land and less than 200 centimeters for peat.
• The soil depth from 3 to 15 metres is largely responsible for the variations of style within this AOC.
• A gradient of soil depth northwestward across the plains results in changes in the herbaceous community and taller grass.
• Gradients of soil moisture, soil depth, elevation and aspect control the distribution of many trees, shrubs and herbaceous species.
• Lettuce has shallow roots and needs a soil depth of 6-8 inches and 6 inches of space between plants.
• Indeed, the design calls for soil depths from 4 inches to as much as 18 inches in some points.
• Soil depth varies from less than deep to deep, and there are only five perennial water sources on the range.
