Abstract
Acidification is recognised as a method for reduction of ammonia volatilisation of manure. During the last two to three years acidification of slurry has become common in Denmark. In 2012 it has been estimated that about 11 % of all applied slurry in Denmark was acidified, and in 2013 it is expected that up to 20 % will be acidified. In all cases sulphuric acid is used for acidification, because sulphuric acid is a very strong acid, it is relatively cheap and it

Abstract
Accumulation of phosphorus (P) in agricultural soils has caused increasing environmental concerns. Maize cropped for fodder implies return of animal manures rich in nutrients. In addition, starter fertilization with mineral P is used in cold conditions for maize cropping. It was hypothesized that the use of the additional mineral P could be excluded by increased availability of the P applied by animal manures. In a growth chamber experiment we investigated the e
