An estimation of the soil moisture content is one of the major measurements in soil. However, there are sometimes restrictions facing scientists when the fields are miles away from the labs, and you need an urgent estimation in which you can save time and efforts. Based on that,
Is there any an accurate device estimates the soil field capacity directly in the farm or field to avoid you using gravimetric method?

After gravitational flow of water in soil after about 48 to 72 hours what ever water reminder in the field according to soil texture about 20 percent water as soil moisture may be considered as field capacity.
Yes ashok thanks , the general idea is quite understandable to be measured a 48 h after the full irrigation. So is there any device has an ability to measure the moisture content in soil directly without going to lab?
