Field moisture
The actual amount of water present in the soil under natural conditions, expressed as a percentage of the dry soil weight or volume at a specific time.

Field moisture is a vital metric for making informed agronomic decisions. Agronomists rely on soil moisture data to determine optimal planting windows, schedule fertilizer applications, and assess the feasibility of mechanical tillage operations.
Monitoring current moisture levels helps prevent operational errors, such as working soil that is too wet, which causes severe compaction, or sowing into dry soil, which often results in uneven crop emergence. Consistent tracking throughout the growing season is essential for accurate yield forecasting and effective irrigation management.
A common mistake is assessing moisture only in the topsoil layer (0–10 cm). Accurate field assessment must account for the moisture levels throughout the entire root zone, as crops extract water and nutrients from varying depths within the soil profile.
