Yes, for 7 zones you take the value from zone 4 as your average index value. Also keep in mind that this here is for pure Nitrogen. If you want to get the total fertilizer amount, you need to devide the result of the formular through the nitrogen content. For example you have a 27% N KAS fertilizer, your Formular Result is 100 kg N and you divide through 0.27, to get 370 kg N /ha of KAS fertilizer.
Hi! Can i define unit/ha to kg/ha and more? Possible to owervrite the attributum table? Because we would like seeding and fertilizing makro and mikro at the same time with one maschine- but the map will define seed/ha only but i will the fertilizing differential
Hi, if you have a variation in your NDVI of 10 % you could decide to also variate your input by those 10 % or by more than 10%. For example for every 10% of variation in NDVI you want to apply 30% more or less input. That's the spread.

Is the calculation formula will be exactly the same for 7 zones maps ?

@@julius_pix4d Would be a great feature to have the method and calculation built into P4DF, rather than having to calculate externally.

Hello, you could try creating multiple maps with different units each.
Anyone know the meaning of the ''spread'' parameter in the type?

Is it possible to use for rice crop?
