Objectives

1. Perform solute displacement experiments using soil columns packed with soils of different textures, analyzing changes in nitrate concentrations with electrochemical and optical nitrate sensors.
2. Utilize the program CXTFIT to compare and evaluate the sensors' experimental versus predicted breakthrough curves (BTCs).

Objectives

To evaluate the effectiveness of winter flooding as a management practice for leaching B from the root zone of almond trees.

Objectives

To evaluate the performance of a potentometric nitrate sensor to two commercially available nitrate sensors for detectng nitrate transport in glass beads.

Objectives

To evaluate the effectiveness of winter flooding as a best management practice for leaching Boron from the root zone of almond trees.

Objectives

To estimate nitrate leaching in an irrigated processing tomato-cucumber rotation field using a three-tiered approach based on:

1. Field mass balance assessments
2. Shallow and deep vadose-zone monitoring
3. Intensive shallow groundwater monitoring

Objectives

This study assessed how conservation practices in sunflower cultivation affects nitrate leaching into groundwater. We employed a three-tiered approach:

• Monitoring groundwater nitrate levels.
• Tracking nitrate movement through the vadose zone.
• Field scale mass balance.
