Abstract

Measurement soil quality of require the attention at role of soil function which vary in space and time and also it’s change. Parameter needed to evaluate the impact of various soil processing at one particular farm. Soil quality represent one of important factor in continue of management and farm use, that is represent the soil ability to present its functions in use of farm or ecosystem, sustaining biological productivity, maintaining environmental quality, and improve the crop health, animal, and human being. Nature of physical, chemical, and soil biology in field used as by indicator of soil quality. All soil data obtained in field, developed to become the index of soil quality. Make an index to the soil quality made to use the method “ Principal Component Analysis “ (PCA), that is chosen an data set the minimum (MDS) from most deputizing indicator of soil function. From various indicator perceived in research area obtained by that clay content, sum up the rustiness, sum up the macro pore, of strength of soil structure, sum up the micro pore, rustiness boundary, and macro amount of fauna identified by as especial indicator of soil quality. From research result got that farm assess the its soil quality index is high (SQI=0,659) of while plantation area assess the its soil quality index lower (SQI=0,411).
