|Interpreting Yield Maps - "I gotta yield map - now what?"||
Yield monitors are the first step many producers take into the age of precision farming. While their cost is reasonable, the commitment of time and resources required to effectively use this technology is significant. A yield monitor, combined with Global Positioning System (GPS) technology, is simply an electronic tool that collects data on crop performance for a given year. The monitor measures and records information such as crop mass, moisture, area covered, and location. Yield data are automatically calculated from these variables.

|Using the Virginia Cooperative Extension Climate Analysis Web Tool to Better Manage and Predict Wheat Development||
Wheat development is affected by nutrients, water, light, and other factors; but temperature consistently determines how quickly or slowly plants move ahead in forming leaves, roots, tillers, and grain heads. The plant's development stage at any point during the season is affected very predictably by how warm or cool the season has been up to that point. This knowledge, combined with educated guesses about how the rest of the growing season will progress, can be extremely valuable information to the grower, who can then make more informed management decisions to include predicting the maturity/harvest schedule.

|Using the Virginia Cooperative Extension Climate Analysis Web Tool to Monitor, Predict, and Manage Corn Development||
How a corn crop develops is affected by many factors: fertilization, rainfall, sunny or cloudy weather, hybrid or maturity group, etc. But these factors generally play second fiddle to temperature in determining when a corn crop tassels or is ready to harvest. Many years of observation have shown that plant development at any point during the season is affected very predictably by how warm or cool the season has been to that point. This knowledge, combined with projections about the remainder of the growing season, can sometimes be used to make mid-season adjustments in management and to predict harvest schedules.
