Soil Fertility Clock-Crop Rotation as a Paradigm in Nitrogen Fertilizer Productivity Control.

The Soil Fertility Clock (SFC) concept is based on the assumption that the critical content (range) of essential nutrients in the soil is adapted to the requirements of the most sensitive plant in the cropping sequence (CS). This provides a key way to effectively control the productivity of fertilizer nitrogen (N). The production goals of a farm are set for the maximum crop yield, which is defined by the environmental conditions of the production process.

Magnesium Fertilization Increases Nitrogen Use Efficiency in Winter Wheat ( L.).

Wheat fertilized with Mg, regardless of the method of application, increases nitrogen fertilizer (N) efficiency. This hypothesis was tested in 2013, 2014, and 2015. A two-factorial experiment with three doses of Mg (i.
