In this experiment, lettuce has been observed the change in the growth and inorganic salts, according to MUD content based on soil chemical properties. In this experiment lettuce has been observed the change in the growth and inorganic salts, according to MUD content based on soil chemical properties. We could expect to soil chemical properties changes in suitable MUD content, to increasing of quantities in lettuce. 1. The change of soil chemical properities according to MUD content 1) Changes of soil pH and EC The soil ph and EC change of MUD content tend to increase pH and EC in all addition ones as pH and EC rate of MUD are going up PH change in the late growth stage showed an increased tendency toward non addition one MUD hydration of the Al ions are dissociated hydrogen ions by constant watering After cropping ,pH showed the result that treat by addition 2S including 6.66 are 6.72, 6.84, 6.96, 7.01 form 4S, 6S, 8S, 10S. So they reached the goal pH 6.5∼7 to optimum affect the validity of Mineral. However, EC increase has a tendency the more grow the lower figure gradually compared with the pH does. Before lettuce growing, EC content of non addition one , and addition one are each 2S, 4S, 6S, 8S, 10S 1.30dS/m, 2.50dS/m, 3.05dS/m 3.75dS/m, 4.75dS/m 5.90dS/m and MUD throughput over the lettuce 6S addition one reduced crop yields in the EC concentration was measured 2S, 4S increase crop yields and affect the content of the EC was measured. And after lettuce grown, addition one of the EC content show each 0.35dS/m, 0.85dS/m, 1.60dS/m, 3.10dS/m 3.90dS/m, 5.05dS/m MUD crops to addition rate increase at all EC levels was lower than before figure. And 2S, 4S were measured the figure under 2dS/m regulation the EC Rural Development Regulations 2) Changes of clay content 2S, 4S, 6S, 8S, 10S according to the treatment of clay content of the MUD respectively, 13.75%, 15.50%, 17.50%, 19.50%, 20.00%, are measured. when the rate of MUD clay content increases about 5-7%, MUD clay content increase soil clay content increase approximately 1-3% MUD proper increasing in clay content of the appropriate content to increase the retention of nutrients in the soil, as well as facilitating anger joined the kidneys to help the roots is considered. 2. Change of Growth according to the MUD Lettuce Growth survey according to the MUD content among Leaf length, leaf width, leaf number, chlorophyll content, fresh weight, and building is in the best condition in mud content 200g. With Leaf length the average is each 14.59cm, 15.59cm, 14.32cm, 13.09cm 11.21cm, 9.6cm from non-addition one, 2S, 4S, 6S, 8S, 10S and all the treat by addition ones were measured high rate to other Treatments. Also, the uncut leaf width has the highest figure in non-addition one, 2S, 4S, 6S, 8S, 10S the average 9.06cm, 10.16cm, 9.13cm 8.00cm, 7.23cm, 6.46cm 2S And the weigh of leaf measured a high figure in the MUD addition 200g compared to other addition ones too. Above result is involved in the soil state of MUD content. MUD content in 200g of the optimum pH, EC due to the absorption of inorganic salts are wholesome state and addition one effects on lettuce growth by promoting entering structure and gaining the contain ability to compared with non-addition-one With MUD content 200g, all Contents are higher than non addition one. After the crops growth main taning the proper content rate except Absorption of inorganic salts in Soil Physicochemical Properties It showed more higher figure than non-addition-one. Since over 600g, however , Lettuce has low influence itself because of too much EC and Na+ with Lettuce growth condition. MUD addition have been affected on growth lettuce increasing and quantity of the lettuce, among them, the best result came from the MUD contained 200g MUD in soil and Soil Physical and Chemical Composition too. Na+ is not the essential factor, so the Absorption rate of lettuce is limited. even if the lettuce do itself can not use Mineral properly because of the Osmotic. Therefore, we expect that too much add mud in soil cause high EC and Na+ so need to have the mud content limited in order to use the MUD as the agriculture field. As a result, the optimum control condition is the MUD content of 200∼300g within about 7% in Wagner pot(1/5000)
