Any ideas on how to increase soil pH?
After years of adding sulphur to our canola fertilizer blend for seeding the soil pH has depleted (6-6.5). Ideal levels are 7-7.5. Some farmers are adding gypsum but it’s expensive and need a floater to apply. Just curious if anyone is experiencing the same and any alternative remedies.
You can add pelletized lime to dry fertilizer. It is only a temporary fix however, it will need to be applied every year. We spread ground limestone for a longer term solution. More money up front, but cheaper in the long run.
Where we farm, Willamette valley, Oregon. Acidic soils are common. Ground limestone is applied to raise soil PH. We can barely get our soils up to a 6-6.5, I’ve had some fields down in the low 4s
Agree with the comments above, we use ground limestone and need to apply a few tons per acre about every 4-5 years to maintain our pH's in the mid to high 6's.
