A Successful Fertilizer Plan Technology better equips you to know a crop's nutrient needs. But the basics of a good fertilizer program still apply. Build on research information and your own knowledge and experience on your fields. Monitor the crop throughout the season.
Soil testing is a basic component.
Sample on a systematic pattern either by grid or management zone to document trends in soil nutrient levels. Scout fields for nutrient deficiencies, and take extra soil and plant samples to document problems. Record location and date. Recent developments regarding timing and placement of fertilizer may require you to re-evaluate your fertilizer program. Soil-test changes, yield data and other records from your farm are valuable resources on what works for you.
