Our friends at the local agronomy center have recommended a 5 gal rate of 10-34-00 liquid starter for a ‘pop-up’ that is safe to use in the row next to the seed.  You want to record this in your nutrient management plan, but are also curious how many units or lbs of N it equates to.  You quick grab your NPM Factsheet and check to see what 10-34-0 weighs per gallon and it is 11.6 lbs per gallon.  You calculate how many lbs 5 gallons weighs and convert it to pounds of N per acre using the N-P-K analysis of 10-34-00.  Your answer is:

Most horticultural crops perform best when soil is in what range?

Every field is completely uniform in it’s lime requirements.

Alfalfa has a soil pH requirement of 6.8. Which is one of the highest pH requirements of all Wisconsin crops.  Your have a crop rotation of 3 years of hay followed by 2 years of corn silage, it’s been that way forever. Your soils have tested low for the target pH at 5.8.  What year of the rotation do you need to apply lime to change your clover hay to alfalfa new seeding?

Soil depth of tillage affects the liming recommendation, the deeper the tillage, the more lime required.

Nutrient deficiencies are rare, but you might be inclined to test in these situations:

Which areas should you avoid sampling when you are probing soil samples?

When should you take soil samples? (multiple answers)

Nutrient deficiencies appear in various parts in plants as they worsen, depending on the nutrient mobility in the plant.  Deficiency symptoms caused by mobile nutrients appear in what part of the plant?

Potatoes grown on sand are great candidates for fertigation, and planning nutrient applications based on petiole sample results.  When does this testing begin in potato?
