The accuracy at which models can predict if weather will favor certain crops or not during growth cycle, it's almost like having a crop consultant in your office who you trust with 100$ worth advice for only 20$. It also does great predictions but I wish they would develop better features such as calculating yield from plants themselves. Sometimes there are errors and its best just to wait till next year. Use this product by all means - it really helps out alot! Accurate enough predicting when rain fall could make or break harvests time wise, we usually have many problems where yields aren't what expected due rainy months not giving our fields good harvest conditions; so being able to forecast these changes has been very valuable information to know early enough as well! I like that you can use it for several different crops, as well as input variables. You can also see your results from previous years in order to help plan future seasons. The interface could be made more user friendly with less technical terms used. It took me awhile to get my head around all the terminology, but once I did, everything else fell into place! We are using this tool to develop our planting plans for vegetable growing season 2016/17.
