You are a professional. You know that in order to do your job you need the right tools. The farmer has at his disposal agricultural machinery and equipment – so you also need those tools that will facilitate your work.
Up to now, as an agricultural advisor, you rely almost exclusively on field observations. Your only tool is your eyes, while in practice there are data that you do not have access to or you cannot easily use.
To provide good advice, you should have a look at all the data without skipping or forgetting any of them. These refer to atmospheric, soil and biological data, as well as nutrition, irrigation and plant protection issues.
