Abstract

This research was conducted on alluvial soils, especially for paddy fields, aimed at restoring soil health and fertility due to the use of chemical fertilizers and pesticides. Through the rate of microbial activity which is controlled by the biohole, periodic investigations of changes in soil acidity, infiltration and electrolyte conductivity levels around the center of the biohole are the centers of microbial distribution.

As a comparison, observations were made using biohole which was only filled with water without microbes. Furthermore, these two conditions, namely biohole with microbes and biohole without microbes, were compared to changes in soil parameters: soil acidity, infirtration rate and electrolyte conductivity levels.

The research was carried out on January to March 2018 at area of  Paddy Field in Nganjuk Districts. The research was use double ring infiltrometer to measure soil infiltration with three replication on each distance from Biohole and use electrolit conductivity meter (EC)  to measure soil fertility by salt ion consentration and soil  acidity.  The measurement was done in every five minute and observtian periode every fifteen days along forty five days. The result of research show that the highest of infiltration rate,  infiltration capacity , fertility & acidity was happened on soil with involve Biofertilizer MA-11, ie 28-55 cm/hour, 223 – 859 uS/cm, PH = 6- 6,5. While the lowest of infiltration rate,  infiltration capacity , fertility & acidity was happened on soil without  involve Alfaafa Microba MA-11, ie 27- 39 cm/hour, 223 – 344 uS/cm , PH 5 – 6
