3 Soil Water Saturation Field Capacity (FC) Excess Water Permanent Wilting Point (PWP) Available Soil Moisture Total pore space Unavailable Water Oven Dry
4 Field Capacity (FC):: Maximum amount of water that a soil can hold indefinitely against gravity (% of volume) Permanent Wilting Point (PWP):: The amount of water remaining i in the soil after plants can no longer pull water from the soil (wilt & die) Available Water (AW) = FC PWP Management Allowable Deficit (MAD):: percent deficit of Available Water (AW) that management will accept

20 Soil Moisture Sensors
21 Soil Moisture Sensors Tensiometers Strengths Soil water tension (same as plant sees) Less expensive Widely used, studied and accepted Not affected by salinity Weaknesses Small sample area Indicates when to irrigate, not how much
22 Soil Moisture Sensors Neutron Probe Strengths Accurate Gives soil water content Large soil sample area Unaffected by salinity or temperature Repeatable Easy to sample at different depths Weaknesses Highly regulated (nuclear device) Can t leave in the field Expensive
23 Soil Moisture Sensors Resistance type Strengths Inexpensive Usable trends Give soil water potential (same as plant sees) Easy to log data Weaknesses Affected by salinity it Imperfect accuracy Samples small area
24 Soil Moisture Sensors Dielectric constant/capacitance Strengths Usable trends Gives soil water content Easy to log data (real-time) Weaknesses Imperfect accuracy Inconsistent (high variability) Small sample area Can be expensive Proper installation is critical, and difficult to do Affected by salinity and temperature
25 Soil Moisture Sensors Time Domain Reflectometry Strengths Accurate Not sensitive to temperature Soil independent Weaknesses Complicated to use Signal analysis equipment is expensive
26 Soil Moisture Sensors The Look and Feel Method Advantages Cheap Easy Forces you to get out in the field Weaknesses Subjective
27 Soil Moisture Sensors Summary Neutron Probe is still the best. All others are not as accurate, and are not as repeatable to varying degrees Most sensors will give a trend that is usable for irrigation i scheduling. Proper installation of sensors is critical and must be done right or data is worthless Not all sensors are suitable to all soil types
