Temperature and precipitation for the three experimental years. A: Air temperature every day (2 m top) calculated because the working common of 5 days, and the imply each day temperature (working common of 5 days) from the years 1991–2020 derived from the close by local weather station. B: Precipitation on a month-to-month foundation and the imply month-to-month precipitation from the years 1991–2020 derived from the close by local weather station. Blue bar extensions point out irrigation, which was primarily carried out within the dry summer season of 2018. Credit: Field Crops Research (2022). DOI: 10.1016/j.fcr.2022.108675
Clover-grass mixtures are standard as a result of they don’t should be fertilized as a lot as pure grass crops. Indeed, legumes resembling white and purple clover are self-sufficient in nitrogen. They can merely repair nitrogen from the environment and repair a part of the nitrogen within the soil. In this fashion, they’ll really additionally present vitamins for the grasses that additionally kind a part of the sphere’s plant group.
“Because legumes are nitrogen-fixing, fertilizing your clover grass optimally will be advanced. This is true for each natural and traditional farmers, as a result of the extra fertilizer you apply the much less clover there shall be, the grass merely out-grow the clover. In standard phrases, you are fertilizing the clover away,” explains postdoc Henrik Thers from the Department of Agroecology at Aarhus University.
This is problematic as a result of the much less clover, the much less nitrogen is mounted.
Organic experiments with cattle manure
Researchers from Aarhus University have carried out natural fertilization trials of clover grass fields to search out the optimum fertilization in relation to area yield, proportion of clover, protein focus and, not least, nitrogen fixation. Therefore, the chosen fertilizer has been cattle…
