If you had one wheel barrow of poop (200 lb) to use on your large 1/2 acre garden, would you get it from the cow barn, pig barn or chicken coop for your sweet corn?

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:

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

Should you insert your probe through crop residue or manure when taking a sample?

The lime reaction, the amount of time required for the pH to reach target levels, is generally:

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?

What color does the Phosphorus deficiency routinely appear as in deficient crops?

Determine the theoretical yield of HCl if 50.0 g of BCl3 and 31.2 g of H2O are reacted according to the following balanced reaction. A possibly useful molar mass is BCl3 = 117.16 g/mol. BCl3(g) + 3 H2O(l) → H3BO3(s) + 3 HCl(g)

Write a balanced equation to show the reaction of gaseous ethane with gaseous oxygen to form carbon monoxide gas and water vapor.

Give the spectator ions for the reaction that occurs when aqueous solutions of K2CO3 and HBr are mixed.
