Nitrogen perspective beckons: making better use of grass protein

3 July 2023 - Cees Veerman en Johan Sanders - 8 comments

t Things got heated in the debate in the House of Representatives about the content of the draft Agricultural Agreement, which did not materialize. That essentially concerns our food production. Protein especially. We have to be careful with that.

The negotiations regarding the agricultural agreement were mainly about the number of cows that we can keep in our country. But in order to limit nitrogen emissions in order to spare nature, it is important to consider the source of the nitrogen problem. We have a million hectares of grassland here in our low country by the sea. This is largely due to soil conditions where few other foods can grow. With so much grassland at hand, you logically also get a lot of cows. It is no surprise that we are the world leader in the production of milk and meat. With the advent of the European Economic Community, borders disappeared so that production would take place where it could best. For us, that was the icing on the cake. Our dairy and meat industry multiplied its production.

Some progress in land use efficiency
Because of our entrepreneurial spirit, we may have gone a bit too far in terms of land use efficiency... With the import of cheap soy protein we could feed the cattle cheaply That with all that soy protein we also import a lot of nitrogen, we let that go too long to happen. In addition, the grassland is fertilized with artificial fertilizer to get more protein in the grass. This makes our grass particularly rich in protein and cows deal with it very 'messy'. A cow uses only thirty percent of the available protein in her digestive system for production and body maintenance. The rest of the protein ends up on the ground and in the air as ammonia and nitrate. The extensive import of nitrogen in the form of soy and fertilizer are the cause of the current problems in our country. The nitrogen crisis. With the export of meat and dairy, not half as much nitrogen goes out of the country as what we take in.

That is why guidelines from Brussels aim at impoverishment of the pasture through less nitrogen fertilization. This way you get less protein in the grass. First of all, they focus on animal fertilizers, because that is where the evil lies. But, now we have to be careful. Worldwide, the demand for animal protein is increasing significantly. That won't change if we close the door here. Then that protein will be produced elsewhere. The waterbed effect.

Alternative schools of thought
There is also another mindset. You may wonder if you can't get all that protein that the cow doesn't use from the grass in advance, before the cow eats it? Yes, you can! When we squeeze the juice out of the grass before the cow gets to eat it, a large part of the proteins that the cow is not using now, no longer enter the digestive organ and therefore no longer appear as ammonia during excretion. And the proteins we extract turn out to be excellent raw materials for pig feed, chicken feed and human foodstuffs. Raw materials that we now import by ship from distant continents. We simply import proteins that are simply available in our grassland in multiples, but which are now lost as environmental pollutants that threaten our nature. 

What prevents us from leaving behind the squabbles from political The Hague and simply taking the bull by the horns. It is therefore time that we 'come to ourselves' and stop getting 'from afar' what we have here in abundance and have neglected until now.

Our perspective
It's simple. We have to think about it and make better use of all that grass protein that our cows now spill, which pollutes the soil. That's possible. With grass refining - extracting protein from grass - and feeding our cows with protein-reduced 'dissolved' grass. Give the dairy farmer an additional revenue model with the production of vegetable protein for human consumption and the chance to arrive at a 'accountable balance of substances'. Here in our country, even better at European level.

This is in response to it Boerenbusiness article:

Dear Mr. Veerman and Mr. Sanders. Always ask myself: why so much dependence! The degree of dependence, that's where it goes wrong every time in agriculture. The revenue model is (rightly) often discussed. The revenue model is not right. Rightly so. The farmers hang dangling at the bottom of the stairs, everything left in the chain is for us. We can set up something again (in this case refining), but what does it ultimately yield for the farmer? We really need to move towards a low-cost system. WUR already made a final report in 2005 on the "low-cost farming system". It was already anticipated that a lot of costs would be incurred, read dependency. Sober and simple was WUR's answer at the time. Nitrogen is not new. As early as the XNUMXs, we as agriculture were confronted with the first measures, the injection of grassland (then nitrate in groundwater). And measures (costs) are added regularly. Costs that cannot be recouped in the market. All the result of "not getting along". A compromise as the cause.

Why are the cows so messy with the protein that we so cleverly put in the grass with fertilizer N? And wouldn't they also be messy with the proteins we put in the concentrates?
It is known that grass/clover mixtures increase the protein content of the grass, but I don't think that can be compared with the quality and effectiveness of the protein that we add to the grass via fertilizer N. And perhaps the most important thing for the cow and the soil is that the protein structure in the rumen is made by the rumen flora and in the soil by the soil life, whether or not in symbiosis with leguminous plants. Both require raw fibre, straw, cellulose and all our "bypass" practices, which want to eliminate the rumen in the ruminants, go directly against Nature with all the consequences such as being messy!

I'm not a cattle expert, but how Louis describes this I see well-defined reasoning.
I know there must be rumen activity and stimulation, is that why almost all cows are thinning? Sometimes you just see it spraying out, which I don't see as being healthy. Seems like an extremely irritated intestines to me, resulting in abdominal pain.

Nice response with the key question:
"Do we still know what being healthy is"?
From the cattle, from the soil, from the food and so on!
Nature has all the answers to these questions, the trick is to find and apply them.

But I am against expropriation or whatever. We have to do something, I agree, but that can be done without bloodshed, people should not see me as a supporter of the Groot, v / d Wal and that whole gang.

It is a very big shortcoming if we immediately lock everyone who has an idea into a box, and then try to put the idea in the same box as well. In the extreme, something like placing the ideas of Autobahn and Volkswagen beetles in the box of Hitler supporters. Expropriation of land is a communist practice and has generally never achieved much result. It also goes against the Constitution, in my opinion, and can only be defended in very special cases. Although I do not like many politicians, I would not and would not call them scum, because they are human beings, despite their ideas and attitudes. But I do understand You Time Bomb.

D66 has responded honestly to the problem: 50% less cattle = 50% less cattle farmers and the other half must extensify with a revenue model. The latter is still not there and Tjeerd can still work on the former. If you think like him, you can use whatever words come to mind. He considers a newt more than a cattleman and then flying and cheating in a radical sense. I think Prof Sanders' protein refining offers a nice perspective. On the other hand, grass in combination with silage maize and own concentrate cultivation is also very effective. In that case, the government should not introduce LVE and grassland requirements on dairy farms. NVWA halved civil servants by setting clear goals and stay away from business operations, stay away from the yard. The efficient production in the Netherlands is more climate neutral than anywhere else in the world, so we reduce CO2 emissions with what we produce here for the food market. The sector should be compensated for this instead of switching to organic dairy farming. Then the CO2 emissions per kg of milk will rise sharply.

The sector is very curious about the revenue model of grass refining. Can this, in combination with manure fermentation, be the solution for many companies?
You can no longer respond.
