EXPERIMENTAL INVESTIGATIONS INTO THE MINERAL NUTRITION OF SEVERAL GRASS SPECIES.

The article presents a study on six grass species, including Lolium perenne, Cynosurus cristatus, Agrostis stolonifera, A. tenuis, A. canina and Nardus stricta, and their respective responses to varying calcium levels in sand culture. It states that the six species were harvested after the treatments at three separate times. Results showed that Lolium perenne, Agrostis stolonifera and Cynosorus cristatus increased their growth with an increase in calcium at lower levels, while A. tenuis and A. canina increased their growth at all levels. Nardus stricta, however, increased its growth in calcium, but was depressed at higher levels.
