This year Farm Science Review is celebrating its 50th show. It is amazing how far agriculture has come in 50 years. One thing we have learned in those 50 years is how important nutrient placement is for crop production and environmental sustainability. Ohio lakes have been suffering the past few years from excess nutrient loading that has resulted in Hazardous Algal Blooms. Fertilizer and manure used in crop production are sources of nutrients transported to Ohio lakes and rivers via sedimentation, runoff and tile discharge.
In July, Directors of the Ohio Department of Natural Resources (ODNR), Ohio Department of Agriculture (ODA) and the Ohio Environmental Protection Agency (OEPA) announced the Ohio Clean Lakes Initiative. This initiative will start the following specific farm level recommendations: 1) Take soil tests and follow fertilization rates as found in the Tri-State Recommendations and/or OSU Recommendations; 2) No spreading of phosphorus on frozen or snow covered ground; 3) Maintain good nutrient application records; 4) As much as possible, incorporate nutrients into the soil layer or on a growing crop at the appropriate time; 5) Follow the 4R Nutrient Steward guidelines found at: nutrientstewardship.com.… Continue readingRead More »
