Is variable rate fertilizer application worth the money?
work with your fertilizer man you can take advantage of certain situations..... i bought a small farm several years ago late, like april 1st...More
It would be great if fbn came up with a verable rate system at a reasonable price using yeild maps
Does FBN have a soil sampling partner for grid samples
Would be great if they did
YES! Why wouldnt you use todays technology to use obtainable yield goals instead of one blanket shot across the field? I have been doing i...More
You guys are too hooked on grid sampling for prescription variable rate. We use yield maps, soil maps and satellite to make prescription var...More
There needs to be a good agronomic reason and philosophy otherwise you can precisely misapply every acre.
I have done 2 1/2 acre grids for around 15 years now, did a gradual build on areas that were low. Applied needed fertilizer plus 10% build o...More
On my clay low Organic matter soils it makes a tremendous difference. The poorer the soil the bigger response you get. All soil types have a...More
Totally agree. I have one farm that is low organic clay. There is only one grid on that farm that needs phos
In the light rolling irrigated soils of Southwest MI it is not uncommon to see 100 bushel yield variance in any given pass. Seed and N defin...More
We did 5 acre grids with variable rate on the P and K. As far as the N goes for corn I apply that at a flat rate. I found that using composi...More
I tried it for 3 years, grid sampled plus variable rated all fertility applications, I did not see a measurable difference on 6000 acres. ...More
it shouldn't be costing you more then your spending now except for the extra soul tests.
You cannot mine a high fertility area in 3 yrs.
We’ve done it for years. We sample and get an rx and then don’t sample again for 3 years. My issue is what about those areas that are said t...More
I encourage you to track the areas that received nothing and see what the levels are on your next soil test. I do 2.5 acre grids every 2 yea...More
You may not save on fertilizer but where it shines is you will be putting more fertilizer where it can be used more to the plant. Custom co...More
What type of cost are we talking in VRF? What situation does it shine? What does the process look like?
$10 an acre to grid sample. That gets me fert and seeding prescriptions also. Good for 4 years but I've done one field longer than that...More
If you're changing your fert from field to field there's no reason not to do it from acre to acre. The same with seeding rate.
**** is that’s it
Even nitrogen isn’t worth it?
