    Default 45 second rationale for the use of cover crops in any soil grow.

    Basically there are main reasons I uses a cover crop (CC)

    1. The early tap roots of the CC provided what I call a moisture sponge of roots that stop the top drying too fast so the bed drys evenly (difference is 2 days no CC 4 days with)

    2. Those crops are N fixers, so they take nitrogen from the air and store it in proportionally large quantities. So when you "mow" or flatten the cover crops they die and release this stored nitrogen in usable form to the soil, via the decaying roots and the mulch on top.

    3. It is well documented that plants living in close proximity talk to each other and can divert essential nutrients to struggling plants. But far more importantly studys have shown that when the cover crops are attacked by pests they can send a signal to the host plant and warn of the impeding problem. Pest choose host plants based on complicated hormone and bio chemical profiles and they look for plants that fit. The signal from the cover crop with cause the host plant to alter its basic chemistry to prevent infestation...

    Thoughts, comments, questions all welcome, I will reply as and when if necessary but be aware Im a little shakey atm

    AND or Herb,will Im sure tell me it took either 42 or 48 seconds in disgust of my inaccuracy pmsl

    Nice one man, technical shizz on the go here. Yeah i know exactly what you are getting at. The nitrogen fixing abilitys of say clover are greatr for lawns. Do you need to use any products to speed up the release of the nutrients within it tho?

    Nice post!

    Question : is there value to CC in coco. Logically I would think yes, so long as you accomodate the extra N? Think I will try with SC 4.

    Where can I source the seeds? What would you recommend Gaz? Would the CC grow in coco? I assume so??? EC would be 0.2-0.3 at the start

    Same. I note trailing lobelia is an early adapter. I had it growing out of the holes in the airpots all summer.

    Had to pull it daily!

    Yes and plant at the same time unless you have a hot soil.you wish the cover crop to cook for you.

    Would things like French Marigolds serve as a pest repellent?

    I am tempted to pull some clover from the garden but know that could back fire badly. Is there some way I can get clover seeds?
