Let's not confuse that there are two reports at play here, the OP (
SkylineAcres16) report shows what is needed.
ZERO lime is needed
For three passes:
First with 18-46-0
40lb/a of P
18-46-0 for example, 46% = P 46 lb/100lb of fertilizer by 40lb need= 87 lb/acre application rate
Also get N 87lb x 18% = 15lb/ acre
Second with 46-0-0
70 lb/a of N. (Now 55lb an acre since we just put on 15lb/acre with the 18-46-0)
46-0-0 for example, 46% = 46 lb/100lb of fertilizer by 55lb needed= 119 lb/acre application rate
Third with 0-0-60
120lb/a of K
0-0-60 for example, 60% = 60lb/100lb of fertilizer = 200 lb/acre application rate.
Not sure what size of bags you buy, but I get them in 500kg (1102lb) bags
For 10 acre field you need:
1 bag 18-46-0 (need 870/ get 1102)
1 bag of 46-0-0 (need 1190/ get 1102) (up the 18-46-0 rate slightly)
2 bags of 0-0-60 (need 2000/ get 2204)
4 bags to buy = but three calibrations to do and three field passes.
From calibrating my Vicon broadcaster, good luck getting exact rates you need, you will find you might be applying what spreader is capable of, i.e. gear, PTO RPM, swatch, granule size, slide opening. I spend a day doing various calibrations and If I wanted 400lb/acre and I found a setting that gave 375lb/acre, and next one up gave 440lb/acre I used the 375.
I'd do it in ONE pass to save time.
12-24-24
550lb an acre = 5500 lb needed, but buy = 5 bags, 5510 lb
One calibration and one field pass.
Nothing says you have to get the numbers exact either, or even use as much as the report asks for.
