| Is there concerns about using manure? I hear you shouldn't use it within 90 days of harvesting anything. So say I use manure, and plant lettuce that will grow before 90 days, do I have a problem? |

| From the U.S. National Organic Program 205.203 Soil fertility and crop nutrient management practice standard. (1) Raw animal manure, which must be composted unless it is: (i) Applied to land used for a crop not intended for human consumption; (ii) Incorporated into the soil not less than 120 days prior to the harvest of a product whose edible portion has direct contact with the soil surface or soil particles; or (iii) Incorporated into the soil not less than 90 days prior to the harvest of a product whose edible portion does not have direct contact with the soil surface or soil particles. There are too many variables to definitively state whether you would have a problem. Lloyd |

| For me, I believe "fresh manure" should be composted (or have set out in field 90 days) before used in a garden... if your using fresh manure in a lasagna style garden, let the garden sit 60 - 90 days before planting. |

| How about worm casting/worm poo? I just emptied out my small worm bin and got a few pounds or worm poo. Is this considered manure too and should be treated the same? |
|
| hadn't thought it as manure before, but technically i guess worm poo is a form of manure... but don't treat it the same. worm poo is the holy grail of composting, the steroid of gardening. you can (and should) use it without hesitation. |

| Nice I got a few pounds. Wish I had more. I have my worms working on making more and hope to harvest again for spring. |
|
| Worm castings are most definitely ready to use when you harvest them. |
|
| The manure from warm blooded animals can potentially have disease pathogens which is the reason for the suggested restrictions on use Lloyd posted. Composting those manures can, if hot composting, kill those disease pathogens, something that does not happen in the soil very easily. Worm casting do not come from warm blooded animals and none of the research I have seen has found disease pathogens in them. |
