    Free or cheap is good ,but I still have a one year old blue grass/p.rye lawn that is not greening up as it should .If anybody has any good natural source of manganese a little help would be appreciated..2lbs of manganese/ k That would require a lot of compost or kelp .

    at that Ph Manganese availability will be severly limited because it will oxidize

    try to bust out a bit of sulfer and sweeten that soil up a bit!

    Where do you get that "micronutrient" pack? Or just bags of mag sulfate? My soil samples came back and I'm low on almost all metal elements, except iron. But they say VERY low for manganese. Wholesale due to large quantities would be good too. Thanks.

    The iron may be high but at 7.8 I doubt the plants can use it. Lesco has a great High Mag combo that I use alot. Also I agree put some sulfer down as well.
