Soil moisture levels change over time and space, affecting agricultural production. By analyzing data from Internet-connected sensors, researchers found that soil moisture is mainly influenced by rainfall distribution, with poor levels from April to July improving after August. Soil moisture varies at different depths, with surface levels being more affected by outside conditions. The deeper the soil, the less variation in moisture levels. Soil moisture is moderately correlated across different depths, with correlation decreasing as depth increases. Spatial correlation is slightly lower before irrigation compared to after.
