MinMaxScaler at Weight Summation

I realized that by summing up terms for our 4 cases, range and magnitude of data is very different which imbalance the equations. Hence, I suggest before sum up the individual terms a minmaxscaling should be conducted for each parameter, e.g: Soil_Moisture= 0.46MINMAX(SM_0(SM_0>0.75))+ 0.24 MINMAX(p_7_acc(p_7_acc>10)) + ...
