Methodology to estimate the number of workable days with farm machinery

In the current agricultural model, it is essential for farmers to know the real time available for the execution of agricultural operations throughout the crop cycle. This is the first step to plan and achieve greater efficiency in these operations, which are subject to climate changes. Meteorological variables in a certain region directly influence the number of days available to work with farm machinery. The objective of this study was to estimate the probabilities of favorable workdays for farm machinery, using meteorological information from the municipality of Santa Maria, RS, Brazil. The conditions to be considered as a favorable working day with machinery were: precipitation
