Uncertainty in neutron probe measurements of soil moisture for irrigation scheduling

Creator:

Wright, Norman D.

Abstract:

Soil moisture in a crop's root zone must be regularly monitored to accurately predict crop water requirements. Most irrigation scheduling services currently use the neutron probe to monitor soil moisture. Unfortunately, there is a degree of variability associated with use of the neutron probe creating uncertainty in measurements of soil...

Relationships between degree of ponding and uniformity of soil moisture distribution under irrigation sprinklers

Creator:

Dehlinger, Charles Robert

Abstract:

Often low intake rate soils need special consideration when applying water during an irrigation. Surface flooding for extended periods may cause adverse crop growth conditions. Properly designed sprinkler systems often eliminate irrigation problems, because the application rate and quantity of water applied can be readily controlled. Research workers who have...
