I spoke with the agriculture teacher today and asked him if he was big in taking a soilsample in hayfields and doing exactly what they called for. He said “yes.” He went over the basics as to why.

I then told him that I guessed I was silly for just blindly putting triple 19, but we got all we needed or more with our spring cutting. His facial expression immediately changed and he said, “Oh, then I wouldn’t worry about it. Most people have the opposite situation, but if you get all you need with one cutting and you are satisfied, I think putting a little triple 19 to give it a boost is fine.”

If you are happy the way it is here is another option. Just put back what you are removing. Several apps and website will tell what a certain yield removes. Then you are maintaining. Something along those lines is the differences in Uk and Watters test. One is just what are removing,atleast what I heard. I have taken the same test split it and sent it to both, what I can't understand is the ph. Sometimes it's off a decent amount between the 2.

UK's AGR-1 tells what a ton of forage removes from the ground. A grass/legume hay removes 35-12-53 per ton.

You need to differentiate between maximizing yield and optimizing yield for your operation and fertilize accordingly. If thats one cutting or four, is up to you.


Currently, I get more than what I need with one spring cutting, and the grass looks really good in the spring.


I agree with SDM and it sounds like you are more interested in optimization and in your case you I see a lot of room to improve optimizing your yield and this can be done economically by just adjusting your pH because as is around 33% of the fertilizer is wasted because the nutrients are being locked up in the soil and not available to your grass.

By adjusting the pH you should optimize the fertilizer's effectiveness while minimizing the cost of your future fertilizer applications. Adjustment of your pH will not only improve the effectiveness of your fertilizer it could also allow you to recoup those bound nutrients from previous fertilizer applications. However this may not be true for your phosphorous if a lot of iron and aluminum are in your soil because phosphorous bound to these molecules are form more permanent bonds. This again shows the importance of monitoring the pH of your soil. In other words, if you do nothing else, lime it.

If it were me, and assuming this is a clay soil, I'd put out 2.5 tons of lime now and then pull another soil test in the spring and see what the soil needs and only apply what the soil test recommends for maintenance. When you get the pH corrected you may find you can grow all the grass you need with little or no fertilizer except when and where you cut hay. Another hidden benefit to this would be by applying less fertilizer your pH will remain more stable for a longer period of time which is another savings.

In the pastures I manage this way I have gone ten years between lime applications because my goal is steady grass growth and not a fast flush so I'm not adding a lot of chemicals which effect the pH. In my view, though pretty to see, a fast flush is futile since production will exceed consumption and what is not eaten during the tender flush loses much of its nutrient value in 30 days and you are left with a lot of rank grass.

Like many have said, get your pH right and I think you will see a lot of improvements in your grass and your bottom line. I'd also suggest adding clover to your pastures if you don't already have it. Nothing wrong with free nitrogen especially when it also yields good grazing. Good luck.

Another reason to get your pH right is that nitrogen fixation begins to drop off significantly when the pH gets below 5.8. The very first money spent on soil fertility should be to get your pH where it needs to be.

Did not call for any lime... but pH is right on the line, and I'm seeing quite a lot of broomsedge in some of the paddocks. Didn't spread lime right now, but I think I'll probably have 2T/acre spread next spring, despite their recommendation. The sedge tells me that it needs it.


Wish I had read this post earlier in the season. I would have mowed it all down. The soil amendment I'm using kept this from coming back as heavy and helped the Bermuda spread in but where I mowed caused the good grass to fill in better. Your post also explains more as where the lime blow off the road is where the grass spread best.

Grass growing on the side of the road and ditches is usually always better than anywhere else.....simply because the county comes thru about 3 times a year and cuts it and lets it lay. Nothing is ever removed.

That's my opinion.....feel free to make it yours.

I explained in another post but the items I am testing have a ph of 4 and the molecules are very small so it allows the plants and soil to take in what normally it could not. The research I found showed increased lime by four times. The county does not mow next to our road but the dust this year blow into the three acres at the front across 1000 feet. In fact it was so noticeable I told my husband we should go down and get lime in buckets from quarry and soak in water to add it to spray but we were not sure and waited. I bought a tester and everywhere tested 7-7.5 so didn't want to mess up the test.

I do agree some grass next to the road does well but around here much is crazy Johnson grass which no one wants in their pastures and the county leaves it to where the seeds spread.

I am going to add one more thing about the test. Our soil is very heavy clay and normally you see small to large cracks in the ground. After the second spraying I have not found one crack and believe this has helped with the fescue and clover coming up easier.

Yes spread when able, my friend sent some samples off for some new ground and they called for 2 ton of lime, he put one ton of lime, 4 tons poultry manure and had good results, but followed up the next yr w/ 1 ton of lime and was fine
