1
Q

Explain how tile drainage works in the field.

A

Tiles are placed 3-4 feet deep in the field and remove excess water. They help with controlling the water table levels and send excess water to an outlet source. Spacing and amount of tile depends on field conditions.

Q

What factors would a producer take into consideration when deciding to implement a grid soil sample into a fields management practices?

A

over applied or under applied nutrients to a previous crop,
if dense livestock populations / homestead site was in that particular field,

19
Q

What is the main problem due to uneven land surface regarding irrigation?

A

uniform distribution of water is difficult

20
Q

Laser land leveling is better than animal driven levelers because it can create a ——————– slope throughout the field.

A

constant / uniform

21
Q

Name one use of the GreenSeeker® discussed in the presentation.

A

Make NDVI maps of fields

22
Q

True or False: Without these types of sensors we wouldn’t be as efficient and effective with crop management practices as we are today.

A

True

23
Q

What allows the no-till air drill to cross contours without leaving skips?

A

The press wheels are located close to the openers allowing seed to be placed at a constant depth over contours.
