That reminds me of the story of the lady who sniffs and eats used diapers.............. Just thinking of it makes me want to toss up lunch... Remember, manures are extremely "hot" fertilizers and should be aged "cooled" before they go into the garden, unless your soil really needs something hot to make it better. Use my method of introducing it into the garden a little at a time, meanwhiles, but the rest in a compost pile or let your chickens work on it for a few months...I like your idea-- both time saving, water saving, and makes for better plant growth.
I ONCE thought about ripping apart my kids disposable diapers that only had pee for the water absorbing granules--- couldn't quite bring myself to do this. A big mess when it is wet and soggy, and well otherwise, in the realm of gross. lol
Can I mix my own equivalent of the Miracle grow Moisture COntrol??
I pretty much depent on the products, or byproducts from my horses to fertilize the gardens.
