SOIL IMPROVEMENT WITH AGROCONSERVATION SYSTEM USING BIOSOILDAM TECHNOLOGY
This analysis aims to improve the soil infiltration rate on Humus agroland by involving biofertilizer MA-11 on the Biosoildam. As control is, original soil without microbial activity triggered. The research was carried out from October to December 2022 at the shallot agroland in Ngawi Districts. The research used a double-ring infiltrometer to measure soil infiltration with three replications at each distance from Biohole. It used an electrolyte conductivity meter (EC) to measure soil fertility by salt ion concentration and soil acidity. The measurement was done every five minutes, and the observation period was every fifteen days to forty-five days. The research results show that the highest infiltration rate, infiltration capacity, fertility & acidity happened on soil with involvement in Biofertilizer MA-11. The infiltration rate shows a constant value of 80 to 120 cm/hour, achieved after the 30th day. Meanwhile, the EC value in stable conditions is achieved on the 30th day, between 950 and 1200 uS / cm, so that the activity of biological agents on humus soil with infiltration levels will be optimal on the 30th day.
