I've read that Kentucky 31 is very tough and easy growing ;making it ideal for heavy use mucky areas (near water trough/gate/barn entrance).The rest of my 2-3 acre pasture I want to over seed/interseed with a timothy /orchard grass/ blue grass "horse mix".However, I keep reading conflicting reports about Kentucky 31's use with horses. I have a 2y/o filly and 10 yr old mare-not going to be bred. I'm confused because some sources say its OK for non-preg horses,others say it isn't good(stunts growth,causes sensitivities)-does anyone have it in their pasture?Is it good for those mucky areas? Also,I'm new at composting my horse manure( use pine pellet bedding). I want to use it to fertilize my pastures, as the grass is sparse and pastures (2 acre each) are on small side.Is using the compost a good way to improve grass growth and strength? How long does the compost need to age?Will the pine deplete nitrogen in the soil if I don't age it long enough? What about lime or bone meal to help "cure" it? Sorry for so many questions,but I'm used to big pastures with low maintenance-I want to max out what little space I have....
