|1)Nitrogen ceiling: 504.4 million kilograms|
The nitrogen excretion in animal manure in 2019, compared to a year earlier, was up by 13.9 mtrillion kilograms decreased to 489.7 million kilograms. That is below the established nitrogen ceiling of 504.4 mtrillion kilograms.
Last year, phosphate excretion declined by 6.5 milkilograms to 155.5 mtrillion kilograms. The phosphate excretion is therefore well below the phosphate ceiling of 172.9 millionn kilogram.
Fewer cows and young cattle result in less shedding
Nitrogen excretion was in the dairy sector last year 279.7 mtrillion kilograms, 10.2 million kilograms (3.5 procent) less than in 2018. Nitrogen excretion from dairy farming has now fallen below the production ceiling of 281.8 mtrillion kilograms for this sector. Last year was the phosphate production of the dairy sector 75.5 mtrillion kilograms, 3.2 miljoen kilogram (4.0 procent) less than in 2018. The phosphate production in the dairy sector is therefore well below the phosphate ceiling for this sector of 84.9 mtrillion kilograms.
Nitrogen excretion from beef cattle came on last year 36.0 mtrillion kilograms, 1.5 ml1 billion kilograms less than in 2018. Phosphate production also fell from 12.1 mtrillion kilograms to 10.2 millionoen. The decreases are related to a lower excretion by veal calves.
Less nitrogen and phosphorus in feed for dairy cattle
Compared to 2015, the year in which the milk quota was abolished, the nitrogen content of compound feed was more than 8 procent dropped to 28.1 gram nitrogen per kilogram. The nitrogen content of silage grass increased simultaneously 7 procent to 29.1 gram per kilogram of dry matter.
The phosphorus content of compound feed decreased from 4.5 to between 2015 and 2019 4.1 gramsm phosphorus per kilogram. The phosphorus content of the silage grass harvest decreased from 4.0 to 3.6 gram per kilogram of dry matter.
Milk production per cow comparable to 2018
Milk production per dairy cow was last year 8 870 kilogram, almost the same as in 2018. As a result, the total feed consumption per dairy cow is also comparable to 2018. Due to the decrease in the number of cattle in the dairy farm and the net decrease in the nitrogen content of feed materials, the nitrogen excretion of the dairy sector decreased.
In 2019, the Netherlands had fewer dairy cows (0.8 percent) and young cattle (8.4 percent) than in the previous year.

Less nitrogen and phosphate in pig manure
Nitrogen excretion from the pig sector declined in 2019 compared to a year earlier 3.2 procent to 93.7 millionand a kilogram. Phosphate excretion decreased simultaneously with 2.4 procent and amounted to last year 36.8 mtrillion kilograms. This is related to the decrease in the number of finishing pigs (0.5 procent) and the number of breeding pigs (5.1 procent). In general, there was less nitrogen and phosphorus in the pig feed.
Since 2016, the phosphate and nitrogen produced by pigs have been below the production ceilings of 99.1 million kilograms of nitrogen and 39.7 mtrillion kilograms of phosphate.
Lower nitrogen and phosphate excretion by poultry
Compared to a year earlier, the nitrogen and phosphate excretion of laying poultry decreased in 2019 by 2.0 and 3.9 procent. Total nitrogen excretion from the poultry sector was last year 56.0 miljoen kilograms. In the poultry sector, a production ceiling of 60.3 miljoen kilograms.
Last year, phosphate production in poultry was down by 25.1 mtrillion kilograms also below the industry ceiling 27.4 miljoen kilograms.
Nitrogen excretion from other animals increased on balance by 2019 1.6 mtrillion kilograms of nitrogen to 24.3 mtrillion kilos due to an increase in the number of sheep and goats and a decrease in the number of minks.
