The results of the proportion of living soil found that all experimental conditions (1) – (6) had decreased EC and TDS values. Experimental conditions (1) laterite soil, (2) untreated eucalyptus activated carbon, and (3) )Cow manure pH values tended to increase slightly and continuously, presumably due to the dissolution of components within the experimental samples. Experimental conditions (4) Household fermented water (5) 50% laterite soil, 50% cow manure and (6) 50% laterite soil, 50% eucalyptus wood charcoal, which has a higher proportion of living soil. The pH value from the 10-day experiment results may have dropped severely. It is caused by the working mechanism of living microorganisms in the soil. The results of unbaked charcoal showed that in experiments (1) – (6), EC and TDS tended to decrease slightly or remain constant. It is expected that this may be caused by water entering the reaction. Experiments (7) - (9) tend to decrease more. It may be caused by the dissolution and mechanism of action of microorganisms in the fermented water. The results of amending the laterite soil with cow manure and household fermented water found that experimental conditions (1) - (4) had little or constant changes in EC and TDS values, except for experimental conditions (5) Laterite soil 33%, cow manure 33%, household fermented water 33% had decreased EC and TDS values, possibly due to dissolution and mechanism of action of microorganisms in the fermented water. The results of improving laterite soil with various types of charcoal found that experiment 1 (1) bamboo activated charcoal (3) Mixed wood activated carbon (7) Eucalyptus wood activated carbon EC and TDS values increased. It is expected that this is due to the water solubility of the charcoal. Experiment 5: Bio-tea bamboo charcoal EC and TDS values decreased severely in the results of the 10-day experiment and then increased later. For the experiment (4) laterite soil 50%, mixed wood activated carbon 50% (6) laterite soil 50%, bamboo biochar 50% (8) laterite soil 50%, eucalyptus wood activated carbon 50% EC and TDS decreased, presumably due to the adsorption of minerals from the laterite soil by the charcoal, as in experiment (2) 50% laterite soil, 50% bamboo activated charcoal. EC and TDS had a small increase in values. Than Experiment No. (1) Bamboo Activated Carbon Effects of improving laterite soil with various types of charcoal. together with cow manure and household fermented water. It was found that using all types of charcoal together with cow manure and fermented water caused the EC and TDS values to decrease. As the proportion of fermented water increased, the EC and TDS values decreased more. Comparing the results of different types of charcoal, case (1) laterite soil 33%, bamboo activated charcoal 33%, household fermented water 33% had the least decrease.
