Biohole Effectiveness Analysis through the Distribution Patternof Microbes at Each Depth in Real Time on Inseptisol SoilWith Digital Biosoildam Technology

Abstract

This research was conducted on inseptisol soils, especially for plantations, with the aim of not only restoring the health and fertility of the soil due to the use of chemical fertilizers and pesticides as well as seeing the pattern of EC distribution at each depth from the center of the biohole based on the time of observation. Through controlled microbial activity, its spread through two types of biohole, namely horizontal and vertical biohole. This research observes in real time through soil parameter sensors connected to the micro controller to changes in soil acidity, infiltration rate, conductivity electrolyte level and porosity level through soil infiltration rate. Through simulations with 2 types of biohole, it can be seen the increase in EC in each depth to the time of observation in real time. From the observations of graphs and EC standards, it can be seen that the ability of the soil to provide nutrients in the root growth zone to support the schedule and distribution patterns of planting both during vegetative growth and generative growth periods. So that we will know the proper biohole distance and spacing in order to be able to provide vegetative and generative mass nutrition based on nutrient values monitored through sensors that change the analogue parameters in the micro possessor into digital information transmitted by Wi-Fi in real time. Inseptisol soils fertility simulation based on the number of microbial populations=108/cfu with variable 1: The effective depth for providing root nutrition to a depth of 30 cm with a soil fertility value or Electrolyte Conductivity/ EC 1000 uS/cm to 1900 uS/cm is reached on the 10 to 60th day. Variable 2: The effective depth for providing root nutrition is up to a depth of 24 cm with a soil fertility value or Electrolyte Conductivity/EC 1000 uS/cm to 2350 uS/cm achieved on the 10th to 60th day.
