Fertility Optimization in Humus Soils Using Digital Smart Biosoidam Technology with Real Time Simulation of the Number of Microbial Populations

Abstract

This research was conducted on humus soils, especially for vegetable plantations, aimed to determine the ability of the soil layer to distribute nutrients and restore soil health and fertility due to the use of chemical fertilizers and pesticides. Through microbial activity that is controlled by spreading through a horizontal biohole, this study observes in real time through a micro controller the changes in soil acidity, infiltration rate, electrolyte conductivity levels and porosity levels through soil infiltration rates. Through simulations with the variable microbial population, it can be seen the level of EC and other parameters against 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 fertility level has not reached=1500 uS/cm with a microbial population=103/ cfu supports the planting schedule both during the vegetative growth period and during the generative growth period, so that we will know when is the right time to do: soil recovery, initial planting and when the tubers/flowers/fruit begin to be conditioned. Until cooked based on nutrient values observed through sensors that convert analogue parameters by the micro controller into digital information transmitted by Wi-Fi in real time. The initial condition before simulating the soil fertility value with the Electrolyte Conductivity (EC) parameter is 744 uS/cm, the simulation results are: Simulation A: To start the growth period (vegetative) is achieved on the 8th day with a EC=1053 uS/cm and in the generative period it is reached on the 19th day with a EC=1529 uS/cm. Simulation B: To start the growth period (vegetative) is achieved on the 17th day with a EC=1007 uS/ cm and at the generative period it is reached on the 36nd day with a EC=1520 uS/cm. Simulation C: to start the growth period (vegetative) is achieved on day 32 with an EC=1050 uS/cm and during the generative period it cannot be observed because on observation until day 45 the electrolyte conductivity has not reach=1500 uS/cm.
