Implement the 4Rs
4R Nutrient Stewardship represents an innovative approach to fertilizer best management practices (BMPs). The 4Rs imply there are four aspects to every fertilizer application and it provides a framework to assess whether a given crop has access to the necessary nutrients. Asking “Was the crop given the right source at the right rate, at the right time, and in the right place?” helps identify opportunities to improve fertilizer efficiency and prevent nutrient movement from each field.

- Placing Fertilizer with Seed Placing fertilizer in-furrow with the seed during planting is a common practice in small grain production and to some extent in row crop production. Placing fertilizer with the seed can be an effective and beneficial management practice, but over application and mismanagement can result in seedling damage, and ultimate stand and yield loss. The type of crop, fertilizer source, row spacing, and soil environment all affect how much fertilizer can be safely applied with seed.
- Nitrogen Loss Pathways - Which is Yours? The well-known poem by Robert Frost, “The Road Not Taken”, kindles our imagination about the richness of life gained by taking the less traveled paths. While it may seem a far reach, this “less traveled path” metaphor also pertains to you and the N nutrition of your plants; whether you are a professional turf or crop manager, or a hobby horticulturalist.
- Split Fertilizer Application Helps Optimize Nutrient Management Split nitrogen fertilizer applications can play an important role in a nutrient management strategy that is productive, profitable and environmentally responsible. Dividing total nitrogen application into two or more treatments can help growers enhance nutrient efficiency, promote optimum yields and mitigate the loss of nutrients.
- Soil Sampling Enhances Crop, Maximizes Fertilizer Use The primary purpose of soil sampling is to get an idea of what the nutrient level of your soil is. Plus, proven methods of soil sampling are essential to develop an accurate fertilizer recommendation. Soil samples provide a representation of the ability of the soil to supply nutrients to meet crop needs throughout the growing season, as well as support your desired yield. In other words, if you don’t know what nutrients are available and in what amounts, your fertilizer application will be off. A precise soil analysis can result in more efficient fertilizer use, increased yields, lower costs and reduced environmental exposure.
- Starter Fertilizer – Why It’s Done The use of starter fertilizer is a management practice with an extensive body of scientific studies supporting its use.
- Keep an Eye on Potassium Cutting back on K for short term economic reasons reinforces the need to monitor crop K nutritional status more closely.
- Soil pH and the Availability of Plant Nutrients The role soil pH plays on the right source, the right rate and the right place.
- The Highs and Lows of Soil Test Potassium Variability Ever get a soil test result for potassium that looked a little odd? You’re not alone and here’s why.
- The Role of Precision Technology in the 4Rs Managing the right source at right rate, right time, and in the right place may be best accomplished with the right tools.
- Not All Fertilizer Bands Play the Same Song P and K bands are not really as harmonious together as you may have thought.
