3 ph and crop growth (vegetables and root crops) Low ph tolerance strong (4.0~5.0) A little strong (4.5~6.0) A little weak (5.5~6.5) weak (6.0~7.0) Potato, taro Crops Sweet potato, white radish, turnip, green bean, carrot, cucumber, parsley Tomato, egg plant, cabbage, cauliflower, broccoli, celery, green peas, melon Spinach, Onion, leek, burdock, asparagus, red pepper, lettus

4 ph and crop growth (grains and pasture crops) Low ph tolerance strong (4.0~5.0) A little strong (4.5~6.0) A little weak (5.5~6.5) weak (6.0~7.0) Crops Rice, tea, tobacco Wheat, timothy Adzuki bean, clover, milk vetch Sugar beet, barley, rye

5 Growth medium ph and the dry matter production of crops: average of 49 crops. Dry matter weight index Root weight Total dry matter Tanaka and Hayakawa 1974 (1974)

6 Al toxicity in hydroponic culture ( Dry matter weight index 6 8A Barley Maize () Yamane (1971) 1971

7 Soil ph and the availability of nutrients Acidic Alkaline ph High Mid Weak Slight Slight Weak Mid High ph Nitrogen N) Phosphorus P) Pottasium K) Sulfur S) Calcium Ca) Magnesium Mg) Iron, aluminum Fe, Al) Manganese Mn) Boron B) Copper, zinc Cu, Zn) Molybdenum Mo)

8 Soil acidity and the growth of crops (1) A Damage by hydrogen ion. B Damage by active aluminum. C Deficiency in calcium and magnesium D Deficiency in phosphate. Binding of phosphate and aluminum.

9 Soil acidity and the growth of crops (2) E Leaching and deficiency of boron. Decrease in solubility of molybdenum and its deficiency. Legumes frequently suffer from molybdenum deficiency. F Excess in manganese. As manganese become more soluble in acidic condition.

10 Soil acidity and the growth of crops (3) G Repression of organic matter decomposition. By ameliorating the soil acidity, mineralization of organic nitrogen and organic phosphorus increase. H Change in microbial flora. Fungi prefer acidic condition, while bacteria and actinomycete prefer alkaline condition.

11 Soil acidity and the growth of crops (4) I Repression of nitrogen fixation. Optimum ph J Repression of nitrification. By liming, the activity of nitrification increases remarkably.

12 Improvement of soil acidity (1) Calcium carbonate (CaCO 3 ) Apply 3 times of exchangeable acidity (y 1 ). Buffer curve method. Gypsum (CaSO 4 ) In the sublayer, Al 3+ is replaced by Ca 2+. High solubility of gypsum helps the reaction.

13 0 Soil ph Added amount of lime (mg / 100g soil) Determine the lime requirement by buffer curve method.

14 Calculation of lime requirement (example) Goal ph 6.5 CaCO mg / 100g soil = 4.2g / kg = 4.2 kg / t Amount of soil in 1 ha, to the depth 15 cm. = 100m 100m 0.15m = 1500 m Mg = 1500 t Bulk density = 1 Lime requirement / 1 ha is = 6300 kg

15 Improvement of soil acidity (2) Apply phosphates in large amounts, because phosphate is hardly soluble in acidic soil. Apply organic matter, to increase the buffer capacity to ph change of the soil.

16 If the soil is made too alkaline, Nutrient deficiency occurs. For example, Phosphate, calcium, magnesium, boron, iron, manganese, and zinc.
