    This is in response to the "seaweed extract thread". I started another thread for ease of locating and indexing.

    Seaweed extract was accused of over night greenup on turf, I decided to test it.

    100sqft of turf freshly mowed at 3.5" by yours truly

    1lb of feed qrade dry kelp meal with 2oz of feed grade wet molasses. 1lb of kelp was applied dry in earthway hand spreader, 2oz molasses was applied mixed in 4gal of water.

    Applied at 1PM, I will post a new pic tomorrow. Honestly I dont expect any real change for a couple days, if any.

    SWEET, I get to "literally" watch the grass grow

    What are your soil and air temps there, microbes aren't doing much below 45 degrees
    What might be interesting is to do the same test when the soil temps get above 70

    Good job. Thanks for letting us in on the little experiment! :)

    Soil temp is right at 45deg, air temp is 46deg. It is suppose to warm up into the 70's starting tomorrow.

    Test area is 100sqft. Its the 10x10 staked off area in the picture.

    This is actually my neighbors back yard. They dont do much with their yard and mine is full of compost and biosolids so I figured I would get a better real world response on virgin ground.

    maybe? but it depends on the exsisting soil, and the temps are still too cold +
    the rate you used is small in the bigger picture of things to see such a responce just from that right now.

    they need a good blow out/raking too,

    I'd like to see 3-week and 5-week pictures, too.

    Thanks! This should be interesting... I plan on running similar tests in my parents back yard... idea is to have it go through the season... mainly using organics maybe a synthetic plot to compare to as we go a long... I am hoping to have some time next week to get it set up and running...

    Now we are talking!!! There may not be changes as drastic as one might hope until the soil warms up, but the kelp and the molasses aren't going anywhere either. If there is no difference by Memorial Day -then we know. :)

    Great post... thanks...

    I did not take a pic yesterday because...well nothing happened. It was still cool all day though, air temp around low 50's. Overnight air temp was still around low 50's and todays high is 80 with a low of 60 so we might see some action over the weekend.

    I will grab a pic this afternoon just for recording purposes.

    I have not used kelp but have seen a dramatic seven day response in two compost test sections that in conjunction with a 20# per K low Protein (apr. 1.5 % N) feed. Color and growth being impressive. The compost source was composted Chicken Manure and composted Leaf/Grass clippings. The response between the compost types at this point very similar and the low N feed only section having very slow response. The feed has a unknown quantity of molasses as a bonding agent for pelletizing.
