How to fertilize blueberries?
Liquid fertilizer should be applied to blueberries by incorporating it into the watering program once per week. Irrigation water should be allowed to run for one hour to fill the irrigation system and moisten the soil at the root zone. The recommended amount of fertilizer solution should then be introduced into the irrigation water for one or two hours, and then fresh water applied for one hour. This method will allow the system to fill with water and moisten the ground, allow the fertilizer to be applied, flush the system of salts and wash the nutrients into the root zone.
What is the most common nitrogen source in blueberries?
Ammonium sulfate is the most often used nitrogen source. Ammonium nitrate and other nitrate containing fertilizers should be avoided because nitrate ions are very damaging to blueberries. blueberries also respond well to fertilizers containing urea, diammonium phosphate and slow release type nitrogen fertilizers.
What is liquid fertilizer?
Liquid Fertilization. Fertilizer may be applied in liquid form through the irrigation system rather than surface applying dry granular material. Fertigation is the term used to describe applying liquid fertilizer. There are some advantages to fertigation.
How to keep fertilizer in solution?
Follow up with a proper and regular watering program after liquid fertilizer is applied. Proper irrigation will allow the fertilizer to stay in solution until the plant has taken it up. If the fertilizer solution dries in the soil, the fertilizer within the solution becomes more concentrated and can become toxic if additional water is not applied. Regular watering between fertilizer applications help to wash the solution deeper into the root zone and encourages a larger, deeper and healthier root system.
What is the best way to inject fertilizer into a system?
An injector pump is the easiest and most reliable method for introducing fertilizer into the system. Most pumps will inject a certain amount of solution per hour. By knowing this ratio, it is easy to apply a recommended amount of fertilizer into the system.

How to fertilize blueberry bush?
Ammonium sulfate also helps maintain an acidic pH. In subsequent years, use the same timing and increase the amount of fertilizer by 0.1 pound each year until you are applying 0.3 pound of ammonium sulfate per bush per application. Be sure to apply the fertilizer completely around each plant because little lateral transfer of nutrients occurs from one side of the bush to the other. Sulfur-coated urea can be used as a nutrient source; however, it is not as acidic as ammonium sulfate and, when used, requires the soil pH be checked more often. On sites with heavier soils and where the pH is more difficult to maintain, plants can be fertilized with Osmocote Plus 15-9-12 at a rate of 2 ounces per plant per month from March 1 through Aug. 1. If you use wood chips or sawdust for mulching, plants may need additional nitrogen at a rate of 0.1 pound of ammonium sulfate per plant for the first few years.

How many blueberry plants per acre?
At 12-by-3-foot spacing, there are 1,210 blueberry plants per acre. If your plant density or spacing differs, simply divide your plant density by 1,210 and multiply the total N to get the adjusted rate, for example (2904/1210)*40 lbs N = 96 lbs N per acre per year, which is the rate for a planting with 3-by-5-foot spacing. yA liner is a rooted cutting that was started in trays. These are small plants with minimal shoot and root growth. xA pot is a liner plant transplanted into a pot to allow for greater shoot and root mass before being planted in the field, usually at 2 to 3 years old.
How to establish blueberry plants?
If the calcium is less than 900 lbs/acre but the pH is 5.5 to 6.5, elemental sulfur should be applied prior to planting to lower soil pH. This may take multiple applications. Resample the soil before forming beds for planting, and if the soil pH is still above 5.4, apply and incorporate more elemental sulfur into the soil. Applying and incorporating monoammonium-phosphate (MAP) or diammonium-phosphate (DAP) at 200 lbs/acre during land preparation is suggested to improve establishment, especially if soils are low in phosphorus. After planting, the plants should be watered to settle the soil around the roots. Fertilization should be delayed for four to six weeks, which will allow the roots to expand from the root ball and begin exploring the soil

Why are blueberries sensitive to overfertilization?
Blueberry plants are sensitive to overfertilization, and the nutrient demand of blueberries is low compared to row crops and vegetables. Blueberry species evolved under the canopy of coniferous forests in acidic soils (4.0-5.4 pH), of which nutrient availability is extremely restricted compared to plants growing in soils at 5.5-6.8 pH. For this reason, overfertilization can cause salt burn to the roots, which is observed as shoot dieback and leaf scorch (Figure 1). This guide explains how to fertilize blueberry to avoid excess nutrient applications while providing adequate plant growth and yield.
What is fertilizer analysis?
Fertilizer analysis relates to the amount of nutrient. The first number is nitrogen (N), the second is phosphorous (P), and the third is potassium (K), noted as N-P-K. Some products express the analysis as phosphate (P2O5) and potash (K2O), and in either case these are the first three numbers that indicate the analysis of the fertilizer. Figure 2 offers an example of 10-10-10 granular fertilizer, whose ratio represents 10% N, 10% F, and 10% K. The proportions are numerically reported as percent (%) of the total by weight. If you have 10 lbs of this fertilizer, there will be 1 lb. of N, P, and K, respectively. A complete fertilizer has only N-P-K; however, N-P-K with added nutrients, like secondary nutrients like calcium (Ca) magnesium (Mg), and sulfur (S), and micronutrients like iron (Fe), manganese (Mn), boron (B), zinc (Zn), copper (Cu), nickel (Ni) and others, will be noted on the label and presented as a percent (Figure 2).
What is density in fertilizer?
Density is mass over volume (mass/volume; g/l or lbs/gallons) and may have been included in the analyses with the liquid fertilizer. If the density is not included, weigh out a gallon of fertilizer. Then calculate the amount of N in each gallon:
