With field preparation starting and planting fast approaching, it is important to know your soil moisture status. Knowing the soil moisture is very important to reduce the impact of field operations on soil compaction. Currently, soil moisture levels across the state are very good. However, as spring progresses, chances for heavy rainstorms increase just as spring field preparation and planting become time sensitive.

The amount of water or moisture in a given mass of soil is highly variable and is important to measure in field studies because it affects microbial activity, nutrient movement, and plant growth. To measure soil moisture content by the gravimetric method, a subsample of a fresh, sieved composite sample or a fresh soil core is weighed, oven dried until there is no further mass loss, and then reweighed. The moisture content is expressed as mass of water per mass of dry soil. Sampling frequency: Depends on experiment and research objective. Soil moisture is routinely measured as part of our LTER core soil sampling for inorganic N, N mineralization, and greenhouse gas fluxes.
