One horse on one acre (is that all available space or is there a house, barn or other structure taking up area?)is not so tight that I see where it would be impossible to have a pile, especially as it is only the waste of one horse. We have right around that area with two horses and use a pile for our manure management.
I agree, my farm is on 2 acres. The house and outbuilds are on .5 acre and the pasture is on 1 acre and the other .5 is undeveloped woodlands.
I control manure in 2 ways. I have a roughly 9 X 9 area I use to compost manure for my farm needs. Its an areobic (forced air) system pipes roof the whole 9-yards and it composts about a yard of horse manure to finish compost in about a month maybe 2 in the winter.
However since the farm generates about 3/4 of a yard per week I have to dispose of the ballence. Depending on how much free cash I have some months I will rent a dumpster from someone who recycles manure, but most of the time I use 3X 90 gallon garbage cans; the plastic rolling ones similar to what the garbage company provides. They live in my barn, they're super easy to roll up and down the aisles to clean stalls and every friday using my tractor I load them in to my truck and take them down the street to a place that recycles manure.
But yes you have 3 choices, so pick your poison.
- Compost it on site
- Give it away
- Haul it away for composting or disposal.
Also fresh manure is consists of a ton of water soluable nitroen which can burn the hell out of all plants, even crops, even corn.
And one thing to keep in mind, in most areas, flinging poop over a fence is the same as dumping a truck load in the forest and is considered "illegal dumping" and in SOME areas, Western Washington being one of them, horse manure is considered a hazardous waste as it it is exothermic (generates heat) and contains bacteria, microbes and is a fecal waste product.
If someone complains to the county or just the police, you could not only be looking at "dumping" fines but dumping of hazardous materials which is way more than just a ticket. And usually someone who is farming a field for food is VERY specific about the soil conditions. Measureing pH, test to determine levels of minerals in order to figure out what is the best ballence of fertalizers in order to maximize their yeild. Throwing manure on someones crops without their permission? I'm sure your boyfriends family adores you, but if their tentant threatens to sue you or them, for your willfully-negligent actions? Not only will they no longer be happy with you but you can be they will definiatly pass the buck on to you and your family. That being said, talk to the person who is leasing the field, TELL them you have a big ol pile of manure you will be setting up, and offer it to them, for them to apply as they deem appropriate.
