    Depending on analysis there may be a ceratin amount of "filler material used in a fert blend. Example 24-5-11 is only 40% nutrient by weight. So a 50lb bag is only 20Lb of nutrients. The other 30 lbs is either a component of those nutrients or filler material to get to the 50 lbs.

    So if your custom blending why not use a maintenance qty of lime to hold pH and only sell lime as needed for those that need more than the maintenance qty. It would save a trip for just liming.

    i dont look at applying lime as another trip, i use it to generate revenue. so additional stops = $$ bling $$

    I look at it as still poviding lime as you and I do now but not making the trip to do it and charge nearly the same $$$$. The lime should be cheaper since it is mixed bulk at the fert plant. We're talking cutting labor by over 15% (5 apps rather than 6). lime is always the slower one anyhow because of the volume of material handled. I can hear it now, cha-ching, cha-ching.:D

    I always use Pelletize lime as my filler. It just makes good cent$ to do this. It may cost a little more but I rather do some good then put down crushed rock.

    personally, i think that is a good idea, however, i have never seen a fert/lime product with more than 7%N...which means if your doin 1lb N you gonna need 14 lbs product per 1000, thats some heavy pushing! Also gonna have a big crunch on profits!

    but thats just me....maybe you guys have seen fert/lime at high % N???

    Actually this is probably a really lame idea considering consider the total fert lbs applied per k and the small amount of lime that could be used for filler.

    Pelletized lime has a fair amount of dust & other "stuff" in it. Assuming the blending plant screens all inbound raws & outbound blends, this is going to be a messy proposition for the blender.

    If no screening, then the blenders off the hook. But the applicators get it instead.

    And at 4 lbs/M, the aperature size of the spreader is small. The pelletized lime MIGHT (I'm not sure) skew the spread patern a little even though we don't see this at the heavier rates that lime is typically spread at (25-50lbs/m).

    How about using 100% filler free fertilizer all the time? Then with all the money saved by the LCO by the end of the year, hire a grunt to pump lime.

    To build 2000 lbs. of 24-5-11 50% PPSCU
    This is the list of ingredients after I forgot the Iron.

    Ingredient.....Amount......Nutrient result.

    46-0-0 Urea....437 lbs.........219 lbs. N
    39-0-0 PPSCU...615 lbs.......240 lbs. N
    18-46-0 DAP....217 lbs.......100 lbs. P
    18-46-0 DAP....same...........39 lbs. N
    0-0-62 MOP....355 lbs.........220 lbs. K
    filler.........376 lbs................0

    If we replace the 376 lbs of filler with Urea, we'd have gotten another 173lbs N into the ton of finished fertilier or another 4 acres treated at 1#N. Or in other words, we'd have made 34-3-11 (or close enough for this exercise anyway).

    If we replace the filler (fertilizer grade limestone) with pelletized Lime, we end up with 9.4 lbs of lime in each bag or .7833 lbs of lime per 1000 if we're going for 1#N.

    We make a 7-1-3 with Lime that I still think is fairly useless because with 14lbs/M of material, the lime quantity is more like 10lbs/M. Unless the soil PH is already darn close to perfect, 10lbs isn't going to do much for you.

    Fun exercise LGF, Thanks

    OK, Let's see who knows fertilizer.

    I made a mistake in those calculations.

    Who's gonna find it first?

    Tremor I found Three

    1. 436 lb of 46-0-0 === 201 N

    2. 217 X 46% X 44 === 44 lb P

    3. 355 X 62% X 83 ===182 K

    The last two are actual P and K
