You Can't Afford to Apply Fertilizer Without A Soil Test

Midwest Labs has a great post about why you should soil test.

The main reason, the high cost of nitorgen and phosporus. We have been talking about the cost of low pH since 2008, Let's look again at what not knowing your soil pH can cost you.

Soil pH testing is the best place to start when planning a fertility program. Having low pH causes plant nutrients to be tied up. According to research done by Midwest Laboratories, a pH of 6.5 ties up 24% of available phosphorus. If your pH is 6.0, then P tie-up increases to 48%, and 24% of N is not available to your crops.

 

The cost of not liming soil at a 6.0 pH, 200-bushel corn goal:

 

Nitrogen  @ $0.54/# 

 24% unavailable  

 150#'s = $81

 $20 /a in wasted inputs

 

Phosphates @ $0.60/#

 

 48% unavailable  

 70#’s  = $42/a

 $20/a in wasted inputs

 

$40/a lost in wasted inputs

 

Yield loss of corn, resulting from low pH, 34 bushels, priced at $6.50 =

$220/a lost in yield reduction due to low pH

 

 A soil pH of 6 can cost your at least $260 in lost revenue.
