Agriculture cannot do without the liquid gold manure

20 January 2022 - Boerenbusiness - 11 comments

There was a program on television about what 2050 will look like. Several people predicted the future. The producer of vegan food also spoke. He clearly preached for his own parish and stated that our livestock is disappearing. Logical when you have lived with the party leader of the Party for the Animals and produce and sell vegan products yourself.

Another scientist stated that producing vegan food has a very heavy footprint. More and more scientists warn against it. When the youth are now raised vegan, they lack certain basic elements found in meat and dairy products. Imitating all nutrients simply does not work and becomes unaffordable. Man is an omnivore and certainly not a herbivore.

Nobody considers the fact that our livestock produces another important product in addition to producing meat and dairy products: manure. This product is going to be called liquid gold in the future. This fertilizer contains all the basic nutrients (nitrogen, potassium and phosphate) for growing plants in the right composition. We can make nitrogen, but potash and phosphate are extracted from the mines. Within a few decades the mines will run out and the stock of phosphate and potassium will be exhausted. Our livestock produces these nutrients in their manure to help our plants grow optimally. This manure is transported to arable farming so that the arable crops can grow optimally, without claiming the potash and phosphate mines.

Nutrients disappear from the farm
Man is the problem. We take all our food from the farmer and so the nutrients disappear from the farm. The people should return their manure to the farmer, but unfortunately. Humans swallow so many pills that our manure has become chemical waste. We leave the water boards with the waste. Nobody, both politicians and environmental organizations, is thinking about this. But when the animals are cleared, they also indirectly clear up arable farming.

In short, agriculture cannot do without liquid gold, called manure. This manure forms the basis for a good and healthy growth of our crops, without exhausting the soil. In 2050 the energy problem will be solved, but the resource crises will be more numerous and bigger. There will also be a fight for the liquid gold manure.

Politicians be careful with livestock farming.

I'll be honest: this opinion contains a terrible lack of insight into mineral flows. I quote: "Within a few decades the mines will run out and the stock of phosphate and potassium will be exhausted. Our livestock produces these nutrients in their manure to allow our plants to grow optimally".

This is a totally wrong picture. Our livestock produces nothing at all, only passes on organic matter and minerals that come from soil and plants. Our livestock eat feed from a soil that is fertilized with mining salts such as potassium and phosphate. We administer those salts, the crop takes it out, the animal eats it and the remains remain organically packed in the manure. Concentrates from far away are also grown with mining salts. If the mines are empty, the animal manure will also be empty, well, in fact, it is no longer there. We can produce nitrogen with leguminous plants, among other things, there are solutions for that. All other minerals come either from mines, or from other sources (such as sea and residual flows), or from the reserves of the soil. For example, on young clay soils, potassium and possibly phosphorus are released during mineralization of clay particles. On sandy soils and old clay soils, this reserve is not there to fall back on.

That is why circular agriculture is so in the picture. The waste streams that we currently leave largely unused, especially our daily excrement, can replace a significant part of it. It may not be the holy grail, but we have to organize it in such a way that it becomes usable again. Struvite (phosphorus) is just the beginning.

Where Jaap concludes that the leak is society, I completely agree. If it is true that in 2050 the energy supply will be fossil-free and problem-free, that would give a lot of space. This will not fill the mines, but for nitrogen it would mean that Yara can continue. The basis that it will be done in 2050 seems to me mainly wishful thinking. Sun and wind don't make any progress, digitization requires a lot of energy, and adding a few nuclear power stations doesn't help either. So let's plan for the time being that the nitrogen supply will be limited and in any case very expensive. We cannot afford the 50% loss that agriculture now has on average from that point of view. As far as I'm concerned, this should draw more attention than the hassle surrounding nature. If we limit the losses, the farmers will save costs and nature will automatically take advantage of this.

there are minerals in the slurry but otherwise it is worthless stuff (shit). On clay you get a bad structure and difficult to work soil. So liquid gold, well no. solid manure and compost can be used for good workability and mineral buffer.

Jaap Majoor, The majority of 75% of your story is exactly right! But also tell this to your Ex, because he still hasn't understood it I think.!? Gr, Hank.

well Ruud you are forgetting a number of things, cattle do not only eat from the bottom, what do you think of all the waste streams that humans are left with or cannot eat. By increasing them, some of them comes back in the form of meat, milk and manure.

Also put a prison sentence on burning chicken manure, among other things.
It is indeed a shame that manure cannot be used for the simple reason that it contains all kinds of junk that pollute the soil.
When does this stop??

What Ruud says is correct. Animals do not produce minerals. They made that mistake a few centuries ago. Rich investors thought they could make poor sandy soils fertile by keeping a lot of cattle. After all, the more cattle, the more manure, the more fertile the soil?!? Only it works the other way around: you can grow few plants on poor soil, so you have little animal feed and even less fertilizer to be able to grow enough plants. This process of enriching poor soil was only possible centuries later: via the supply of fertilizer or via the supply of animal feed from outside. It is true that manure will become much more expensive. But that is less favorable than cattle farmers would like to think: that only happens if the raw material for the manure - animal feed - is even more expensive.
Hub Rich 21 January 2022
By the way, there is another method that works. If the livestock shrinks by 20-30%, the manure no longer needs to be transported to Paris and Berlin. Is this calculation correct: suppose a pig farm with a thousand pig places x 1 m3 per year x €17 = € 17.000 per year is half an annual income? My position is therefore that the only sector that will benefit from the decline in livestock is livestock farming. It is favorable for arable farming that the livestock does not halve but doubles.

In the Netherlands we are lucky that we have enough manure, which results in very good soil quality where the crops do not only grow with fertilizer, as in our neighboring countries such as France where a lot of money is paid for our manure to absorb the humus that is so much needed. jacks, they have been looting for years and now have to repair it, which takes years. If we stop the manure production here, the same will happen to the Netherlands, and our posterity will not thank us for it. We now have the knowledge, it will have disappeared. Also vegetarian food needs nutrition and manure has all the components of plant food in it, so the cow and pig farmer cannot do without the arable farmer and the arable farmer cannot do without the cows and pig farmer, balance is always the best in all things.

Huib Rijk, this person is not at all about the facts, I am building a stable, I do not yet need to have him ready, but this will certainly come, I already knew when I started it, I am sitting on poor sandy soil, and if I don't make sure I have enough manure, idiots like this Rich, will make us all poor

Me, if you read Huib carefully you will understand how intelligent he is and ...
