In 2019, nitrogen excretion in animal manure fell by more than a year earlier 13 milmillion kilograms. That is 14 mtrillion kilos under the established nitrogen ceiling of 504.4 milmillion kilograms. It is for the second consecutive year that the nitrogen excretion falls below the ceiling.
The nitrogen excretion of the dairy sector last year 280.6 mtrillion kilograms, 9.3 mtrillion kilograms less (-3.2 pcents) than in 2018. Nitrogen excretion from dairy farming has now fallen below the production ceiling (281.8 mlmillion kilograms) for this sector.
Phosphate excretion animal manure further below ceiling
The phosphate excretion decreased by 2019 6.0 mlljoen kilogram, a decrease of 3.7 pteacher compared to a year earlier. The amount of phosphate in animal manure has fallen for the third consecutive year and is now 17 mimillion kilograms (10 procent) under the phosphate ceiling of 172.9 mbillion kilograms set by the European Union.
Last year was the phosphate production of the dairy sector 75.1 mtrillion kilograms, 3.6 mtrillion kilograms less than in 2018. The phosphate production in the dairy sector is therefore almost 12 punder the phosphate ceiling for this sector (84.9 mtrillion kilograms). Beef produced beef 11.8 mtrillion kilograms of phosphate, spacious 2 pless than the year before.

Fewer cows and young cattle
In 2019 the Netherlands had on average fewer dairy cows (-0.9 procent) and young cattle (-8.4 pteacher). In the last quarter of 2019, however, the number of dairy cows increased so that by the end of 2019 there was almost 30 dua thousand cows were more than on 1 yesnuari. The number of calves, heifers and heifers remained constant.
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 decreased by more than 7 percent to 28.4 gram of nitrogen per kilogram. The nitrogen content of silage grass increased with the same period 7 proto 29.1 gram per kilogram of dry matter.
The phosphorus content of compound feed fell between 2015 and 2019 from 4.5 to 4.0 gram phosphorus per kilogram. The phosphorus content of the silage grass harvest dropped from 4.0 to 3.6 gram per kilogram of dry matter.
Milk production per cow comparable to 2018
The 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 dairy farming and the on balance reduced nitrogen content of feed materials, the nitrogen excretion of the dairy cattle sector decreased.
Decrease in nitrogen and phosphate in pig manure
The amount of nitrogen and phosphate in pig manure decreased by 2.7 and, respectively, in 2019 2.9 pteacher compared to 2018. This is related to a decrease in the number of meat pigs with 1.1 procent and the number of breeding pigs with 6.6 procent. The effect of changes in feed composition has not yet been included in the figures.
Nitrogen excretion from the pig sector came out in 2019 94.2 mlljoen kilogram and the phosphate excretion 36.6 mtrillion kilograms. The nitrogen and phosphate that pigs produce have been under the production ceilings of since 2016 99.1 mtrillion kilograms of nitrogen and 39.7 ml1 million kilograms of phosphate.
Lower nitrogen and phosphate excretion by poultry
In 2019 the nitrogen and phosphate excretion of laying birds decreased by almost 6 procent compared to a year earlier. Manure production hardly changed in the poultry sector. The total nitrogen excretion of the poultry sector last year was 54.5 mtrillion kilograms, well under the production ceiling of 60.3 mlljoen kilogram.
The phosphate production of poultry in 2019 was 24.7 milliona kilogram also well under the ceiling of 27.4 milmillion kilograms.
On balance, manure production from other animals increased by 2019 1.3 ml1 kilogram of nitrogen up to 24.0 milliona kilo due to an increase in the number of sheep and goats and a decrease in the number of mink. Phosphate production remained tight on the spot 8 mtrillion kilograms.
