This is Part 2 in Jim’s series. If you missed Part 1, here you go!

When you feed hay for fertilizer, we often think of it as a way to reduce the need for purchased fertilizer, especially Nitrogen (N). Have you thought about how much N you may actually be applying when you feed hay?

It may be more than you think.

Let’s Look at How N Moves From Fed Hay Back to the Soil

The amount of nitrogen in hay is directly tied to the protein content of the hay. Protein on average contains 16% N. Grass hay may have less protein than the livestock being fed require while legume hay generally has much more protein than required.

If the hay is just what the animal needs in terms of protein content, then about half of the N will be excreted in the feces and half in the urine.

Livestock will generally excrete 85 to 95% of the N consumed.

Fecal N content changes very little as dietary protein level increases.

N is slowly released from manure piles as they decompose. feces breaks down relatively quickly in warm, wet environments and very slowly in cool, dry environments.

Almost all excess N ingested by the animal when protein content of the feed exceeds the animal’s requirement is returned to the soil via urine.

Urinary N is a highly soluble & readily available N fertilizer. When managing hay feeding for targeted N application rate, urinary N is where we focus our attention.

This table shows how much urinary N is returned to the soil depending on the protein content of the hay.

When you decide how many bales of hay you will be feeding on an acre of pasture, this table can help you decide.

If you set a target amount of N to apply, you can determine how many bales per acre it will take to accomplish that application rate. You can see the number of bales to feed per acre will vary greatly depending on the quality of the hay being fed.

Do you have a nutrient management plan or are you missing a great opportunity and wasting resources?

Coming next week – Jim provides some background to help you figure out a plan to manage the nutrients from your hay feeding. If you have questions for Jim, do share them in the comments below!

We think it is far more important to stop making hay on your land than it is to stop feeding hay on your land. Here are some things to think about.

What Made Sense in 1973 Doesn’t Make Sense Today

Making hay is a whole lot more expensive than it used to be. This table compares input costs for making hay in 1973 in contrast to 2013.

 

All of the input costs have increased at a much faster rate than the value of beef cattle, lamb, or milk. To be on par with costs experienced in 1973, fed cattle should have been $284/cwt, not the $148 they were.

Hay = Inexpensive Fertility

While making hay is expensive, in much of the US, hay can be bought for less than the cost of production. When you buy someone else’s hay and feed it on your property, you are buying their fertility at a highly discounted rate. In some years in some locations, you can buy beef cattle hay for less than the fertilizer value it contains.

This is a great opportunity for improving your land in a way that also benefits soil health.

Feeding Uniformly is the Key

The key to soil improvement is to get the hay fed uniformly over your pastures. This is how you can realize the greatest benefit from purchased hay as a planned fertility input.

Large round bales are still the norm in much of US cow country. Round bales can be unrolled with relatively low-cost equipment. Bales don’t unroll uniformly all the time, but the subsequent manure distribution is way better than feeding bales in ring feeders.

Big square bales can be flaked off easily in a systematic way to cover a specific area with each bale fed.

Bale processors are expensive pieces of equipment. If you are invested in something like this, make sure you are feeding all of your hay to optimize the distribution of manure across the pasture.

We need to be thinking about how much nitrogen and phosphorus is in each bale we are feeding so we can plan our daily feeding to apply appropriate levels of nutrients rather than feeding too little and not realizing the benefit we expected or feeding too much and overloading the soil and environment with excess N. We’ll look at that next week!

Stay tuned! Jim will be covering all the data and math in this series to help us figure out how to do the best we can at improving pastures with hay feeding. If you have questions for Jim, do share them in the comments section below!
