relative_yield

This function calculates the relative yield of an observed
dry matter yield compared to the reference dry matter yield
in the Swiss fertilizing guidelines GRUD2017_ch8SoilManageR.

Calculate numerical agricultural soil management indicators from on a management timeline of an arable field. Currently, indicators for carbon (C) input into the soil system, soil tillage intensity rating (STIR), number of soil cover and living plant cover days, N fertilization and livestock intensity, and plant diversity are implemented.
The functions can also be used independently of the management timeline to calculate some indicators. The package contains tables with reference information for the functions, as well as a '*.xlsx' template to collect the management data.
