Do I need to test my soil if my immediate neighbor has done the analysis? Can I use his/her recommendations?

Our recommendations are based on the soil from that particular field. Your neighbor may have grown different crops, applied different amounts of manure or may have different soils. There are many factors that will result in variation in fertility across a very small distance. It is extremely dangerous to use a neighbours’ recommendations, as it could results in expensive mistakes, meaning you applying completely the wrong inputs and actually causing your soil fertility to swing out of balance, resulting in less production and more soil related problems. Invest in testing your own farm soils, you will never regret it.
