Definitely observe your land for a year as stated above. The bigger the land, the long or more time you will need to spend observing it. When I moved to my house in the suburb I jump right away at creating gardens and didn't take the time to observe (this was before I discovered Permaculture less than two years later). As a consequence I had a water management issue because I not realise how much water was coming off my roof and from my neighbour (30-40 feet away). I mitigated the issue but I could have avoided the extra work and headache had I took the time to observed even in my suburb backyard. In fact I may have done things differently looking back.
While you spent the time observing your land for at least one full year, read and watch as many video from Geoff Lawton, Martin Crawford, Sepp Holzer, Joel Salatin (farming aspect), Brad Lancaster (water management) and anyone else online doing permaculture or something related to it (organic/biointensive farming, agroforestry, forest garden, aquaponics...)
