Ooo...great info- thanks for posting this.

Thanks 41n... on the Alfalfa Hay (Alfalfa Hay: 2.45/05/2.1) do you think the 05 for P is supposed to be 5% or .05%? I'm guessing .05%. or maybe 0.5%

Looks like I need to find a truck load of dried shrimp heads

I assume it means 0.5%. It would probably be in the same ballpark as alfalfa meal, which has an NPK of 2.8-.3-2.4 - at least according to the Grass City forum.

Thanks, I'd bet you're right. I use quite a bit of alfalfa hay because, even at $20/bale, it is cheaper to buy alfalfa than to pay for the water to grow a cover crop/green manure crop. Thanks for the info.

Thanks fortyoneorth. great info......Fabulous

Good Stuff. Ami

I love using alfalfa cubes because they are cheap. My main source of compost is my four horses manure, which is nearly straight manure with a little much needed desert sand ( I'm on clay, the horses are boarded on sand) and a bit of the alfalfa they don't eat. The alfalfa is non-GMO and weed free. It composts down to beautiful soil when mixed with my never- ending supply of pine needles. I add the pine needles to prevent the manure from getting too dense and compacted. The plants seem to love the mixture. This fall, I'm building and also topping off some beds. Also adding some wood shreds/chip pings from my pines and lemon trees, African sumacs. I have a mountain of branches I'm chipping and shredding, in addition to pine cones I'm shredding.
When added to the horse manure, it's amazing how fast this stuff composts. Even when I do it lasagna garden style. The bottom layers of the garden are rich, black dirt within six months, full of red wigglers.

Thanks for the NPK table. I wonder why the figures are quite a bit different than this table?

I had heard so much about goat manure, I was disappointed to see it listed so low in N.

[RayR]

Like so many other things in nature, there are no absolutes. The NPK of manure will depend on diet among other things I'm sure.

[ScottinAtlanta]

Sure, but it would be good then to publish ranges, not single point estimates. Just a quibble, but could make a big difference to results if there is wide variation.

[fortyonenorth]

Two things to keep in mind.

First, even though the various manures have low NPK ratings, you're going to be adding a LOT of manure, when compared to how much synthetic or organic fertilizer you might add. If you were using blood meal, for example, you might be adding ounces per 100 sq. ft. whereas with manures you'll likely be using pounds.

Second, manures (and compost) promote a biologically active soil which, in turn, helps to release nitrogen from organic matter and humus. So, the real-world "N" value (and "P" and "K" for that matter) are greater than what's printed on the label.

[Tracydr]

How do you easily compost orange skins? Will the food processor do a good enough job! I don't want to ruin the food processor so I've just been dumping huge amounts of citrus hulls after juicing. Thinking I'm waiting a very good resource that could go in my lasagna garden.

[walkinggin]

We have two huge trees and between the two fresh oranges year round. We throw loads of juiced orange rinds into a very active compost bin that is continuously added to and turned frequently. The rinds break down very quickly, less than a month even in winter.

[Tracydr]

Good to know they break down quickly. I'm just going to start throwing them in. I always thought they were a no-no for some reason.
