Vertical Extension of Soil Moisture Data in Hungarian Soil Types with Different Interpolation Methods

Abstract An important step in today’s modern precision crop production systems is the development of an irrigation system for arable lands. Most these only examine top, 10 cm layer soil. The problem that root crops also penetrates and grows into deeper layers while absorbing water. For this reason, there a need cost-effective solution to quantify amount water up 1 meter depth. Sentek EnviroSCAN sensors were used measure soil moisture (SM) values different types located Hungary having mechanical chemical attributes. SM measured at certain depths. missing depths are supplemented with estimated data done by interpolation. However, estimations not enough, as on types, i.e. one kind interpolation method may be suitable all without significant statistical error. Several deployed. Each them placed specific type. depth then produce lasting from 100 using 8 methods. was performed Python framework called Scipy. final result research evaluation model performance methods Hungary.
