What is the Economic Value of Cattle Manure?

Economic value can also be gained from a yield response to manure. ( Wyatt Bechtel )

Manure has value. That value may result from improvements in soil quality, increases in yield, and replacement of commercial nutrient required for crop production. Previous articles on manure’s value have focused on its soil health, environmental benefits, and tools for estimating manure’s value. This article will focus on the economic benefits of manure. Key take home messages include:
1) Targeting fields requiring supplemental phosphorus (P) produces the largest economic value from manure. 
2) Targeting fields requiring supplemental potassium (K) significantly increase manure’s value. 
3) Additional value result from manure nitrogen (N) and micro-nutrients as well as from yield increases. However, these benefits are typically less important than P and K.

The assumptions used for this analysis are found at the end of Figure 4.

Nitrogen and Phosphorus Value

Manure is a supplemental source of P, organic-N, ammonium-N, and micro-nutrients commonly required by many fields. Cropland receiving surface applied manure (not incorporated) benefits from both the organic-N and P. The value of the nutrients in beef manure (open lot) is heavily influenced by the value of the P and to a lesser extent the organic-N (see Figure 1 and assumptions for all figures presented. All assumptions are found at end of article. ). Because feedlot manures and many solid manures contains little ammonium-N, incorporation to conserve N would produce little additional value.

Figure 1 What is the Economic Value of Beef Manure Koelsch January 2018 BeefWatch

For slurry manures such as captured by a beef barn with a pit below a slatted floor, immediate incorporation of manure is important for gaining value from the important ammonium-N content. Slurry manures generally conserve the ammonium-N fraction commonly lost from open lots. Figure 2 illustrates the value of incorporating beef manure with a below barn pit. Approximately 35% of its value results from the ammonium-N conserved by direct injection.

Koelsch Figure 2 Corrected January 2018 BeefWatch

Note the importance of P to achieving value from both of these manures. Almost half or more of each manure’s value will only be realized by applying manure to fields requiring P supplementation (typically, fields with Bray soil P levels below 30 ppm). Thus, farmers wanting to gain the greatest value from manure should target those fields with low soil P levels. A 25 ton load of open lot beef manure has a fertility value of $350. However, 2/3 of this value will not be realized if applied to a field with high soil P levels. 

Potassium Value

To further enhance the value of manure, targeting those fields that have a K requirement offers additional value. Soil tests for highly productive fields are increasingly identifying a need for K supplementation. Manures are an excellent source of K. For the beef feedlot manure example shared in Figure 1, the manure’s value has almost doubled by applying it to a field with a K requirement (Figure 3).

Yield Response

Economic value can also be gained from a yield response to manure. Such yield responses can be a result of improved soil structure and greater drought tolerance of the soils receiving manure or from the increased biological activity in the soil producing a number of benefits such as greater nutrient availability to the plant. A recent worldwide literature review of 159 research comparisons of the nutrient replacement value of manure observed an average yield increase of 4.4%. Adding a 5% yield increase to a 200 bushel/acre corn crop will produce some additional value. However, note that this yield boost does not compare with the value of the P and K in manure (Figure 3) assuming a 5% yield increase is achieved. 

Similar benefits are observed for manures produced in other beef systems houses in open lots, bedded back barns, and barns with a deep pit as illustrated in Figure 4

Keys to Manure Value

Key to gaining the economic value from manure nutrients is the rate at which manure is applied. To receive the returns shown in this articles graphics, the following practices must be followed:
1. Manure should be applied at a rate that does not exceed the crop N requirements for a single year. Excess manure N application is likely to be leach beyond the root zone and be lost. See Determining Crop Available Nutrients from Manure or more information.
2. Manure applied at rates near the crops N requirement typically over apply P and K. However, these nutrients will continue to be available to crops in future years. To gain the manure’s P and K value, target those fields requiring supplemental P and K (see Nutrient Requirements for Agronomic Crops in Nebraska or your state specific recommendations). In addition, avoid re-applying manure to the same field until soil testing suggests need for supplemental P and K. 

Accessing the economic value of manure begins by targeting fields low in P and K.

Dr joy is a trust worthy spell caster and he will be of great help to you. I never believed in spell casting but After 4 years of marriage my husband left me because I lost my womb, and i was unable to give birth to children. I felt like my life has come to an end, and i almost committed suicide, i was emotionally down for a very long time, but thanks to this spell caster called Dr joy whom i met online after my friend Becky Ross told me how he also helped her to bring back her husband in less than 2 days. I believed her and decided to give Dr joy a try and i contacted him on his email joylovespell@gmail.com. and explained my problems to him. He laughed and told me that In less than 2 days, my Husband will come back to me again, and that he will restore my womb and i will give birth to children. At first i thought it was a joke but i took courage and believed as Dr joy has said and it did happen just as this Great spell caster said, My husband called me and was crying, begging for forgiveness. I forgive him and today i am so glad that all worries and problems has gone away, and we are even happier than before, another good news is that i am pregnant now, and very soon we will have our baby.

Hi everyone,
I'm so excited. My ex-boyfriend is back after a breakup, I’m extremely happy that will are living together again.
My boyfriend of a 4yr just broke up with me and am 30 weeks pregnant. I have cried myself to sleep most of the nights and don’t seem to concentrate during lectures sometimes I stay awake almost all night thinking about him and start to cry all over again. Because of this I end up not having energy for my next day’s classes, my attendance has dropped and am always in uni and on time. Generally he is a very nice guy, he ended it because he said we were arguing a lot and not getting along. He is right we’ve been arguing during the pregnancy a lot .After the break up I kept ringing him and telling him I will change. I am in love with this guy and he is the best guy I have ever been with. I’m still hurt and in disbelief when he said he didn’t have any romantic feelings towards me anymore that hurt me faster than a lethal syringe. He texts me now and then mainly to check up on how am doing with the pregnancy, he is supportive with it but it’s not fair on me, him texting me as I just want to grieve the pain and not have any stress due to the pregnancy. i was really upset and i needed help, so i searched for help online and I came across a website that suggested that Dr Azeez can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and he told me what to do and i did it then he did a spell for me. 17 hours later, my bf came to me and apologized for the wrongs he did and promise never to do it again. Ever since then, everything has returned back to normal. I and my bf are living together happily again.. All thanks to Dr Azeez if you have any problem contact Dr Azeez now and i guarantee you that he will help you. Here’s his contact. Email him at: Azeezabdulahi12@gmail.com
