Land Considerations

As i get older, i’m more aware of how much time and hard work a piece of property can be.  Many years ago, my grandpa gave me a 160 acre piece of his land and i now realize that he was about my age now when he gave it.  I was much younger and was thrilled, but now i can see that he was probably tired of managing and fixing all its problems.  In fact, it is only about the east 80 acres of the farm i now have that incurs 80% of the work i do on the 520 acres i now own/manage.  (it is a sad reflection of our time that in north Missouri that is no where near enough property to make a living on).  At the same time, it’s the corner of that piece that is the best for working and loading out livestock.  (interestingly, my daughter, at about age 11 made the comment, ‘i don’t like this farm, it is too much work!”)

Truth be told, if it was possible for me to control the land to the north of me and to the south, i could all but eliminate the massive erosion and washing problems which cause my little piece to be so much work.  But i don’t, so difficult repairs are recurring.  Controlling the ‘heads’ of the water by building ponds or dams would practically stop all but the worst rain events which cause such destruction.  The biggest help would be to seed down the hills that are being farmed every year.  There are no roots to hold any soil in place and increase water infiltration on acres and acres of slope.

So, a point i’m trying to make is – look to your future self when purchasing a property – is this property you are considering fixable?  or will it be constant work?  We actually looked at a property last year that was adjoining and for sale, but with all it’s deep ditches and no control of the head, it would be more work than what we wanted to take on now at retirement age.  It is FAR too much asking price anyway.  (It’s still for sale)

The water rushes through this gap so high and fast that there is brush and sometimes huge logs on top of the sealed road you see in this photo.  This time, there are only a few small pieces on the road, my fence caught most of the trash.  The fence is laid over so much, that i’ll actually take the wires off the two posts you see, pull the posts and reset them on the inside of the trash and it will still be in line with the existing fence.

using my post puller  (from Hometown Hardware, Brookfield, MO) at a funny angle, but it worked!  i put a small log underneath the ‘foot’ of the contraption so it wouldn’t sink into the mud when i put pressure on the handle.

All set to cut this piece of tin off because it’s so buried in the sand and mud, i couldn’t pull it out.  Took the photo, picked up the DeWalt reciprocating saw, clicked it off safety, and pulled the trigger.  Nothing, no power, what?!  Well, clearly you can see what i couldn’t – i forgot to bring a battery with me.  So, i will do this part of the repair on Friday when i come back to my farm.  UGGGHH!

This one was a bit of a pickle, but after scratching my head a bit, i figured out a plan.  thank goodness i got a ‘B’ in geometry.  Farming and ranching is a LOT of problem solving with the tools you have on hand and putting them in the right order and angle.

For fun, i found this map which shows the watershed area through which this one watergap i’m repairing all the runoff water passes through.  I measured the area and it encompasses 560 acres of surface land area.  When we get gully washers, which do come at least 3 times a year, that’s a lot of water rushing down Lick Branch – no wonder my fence gets washed out every time.

We have so far only considered the role of buying and feeding hay as a Nitrogen source for your pastures. Hay is also a great source for slow-release Phosphorus to benefit your pastures.

Manufactured P fertilizers have recently been shown to be detrimental to the presence and function of beneficial mycorrhizal fungi in the soil. Using fed hay as a P source rather than concentrated soluble fertilizers feeds the fungi rather than diminishing them.

Factors Limiting Plant Growth

Nitrogen is generally considered to be the first most limiting nutrient for plant growth in terrestrial environments. Phosphorus is very often the 2nd most limiting nutrient. Unlike the N fixation process carried out by legumes in association with Rhizobia bacteria, we cannot create P out of thin air.

P is critical to both plants and animals as all energy transfers within plant and animal are mediated by P containing compounds. Abundant P is necessary to have healthy pastures and livestock.

Almost all P excreted by animals is in the dung. Because most cattle defecations occur when the animal is at rest, dung tends to accumulate where animals congregate – on the feeding line for example, or where cattle bed in hay not consumed. It does not get spread out over the entire pasture area if feeding is limited to small areas of the pasture.

This why spreading the hay out in the feeding process helps the P cycle.

Excess Nutrients Cause Problems

While P is a critical component of life, it also has pollution potential if we are allowing manure to concentrate in areas prone to surface runoff and soil erosion.

Mismanaged hay feeding can lead to excessive runoff of fecal material into surface water leading to aquatic weed growth and algal blooms. The ‘dead zone’ in the Gulf of Mexico and Chesapeake Bay are due to P runoff as well as N runoff.

How Much P Does Hay Feeding Provide?

Using our previous example of bale grazing with over 20 tons of hay/acre fed, the P load would be about 80 lbs/acre. That is not an excessive amount of P, although the N load was quite high.

Since that P is almost all contained in dung pats, it is slowly released back to the soil through microbial decomposition processes. The greater the biological and insect activity in the soil, the quicker the release process.

We only have a possibility of P contamination of surface waters when there is actual water runoff and/or soil erosion taking fecal particles and soil to the riparian areas.

The key to minimizing risk of P pollution from hay feeding is keeping the feeding areas well away from surface water.

Let’s keep them high & dry!
