Not all nitrogen sources are created equal!  

As fall approaches, Florida citrus growers face concerns about input costs. While cost is a priority, it’s essential not to assume that all nitrogen sources function equally in citrus production. Beyond initial cost, other factors play a crucial role in selecting the right nitrogen source. Some factors include the availability of the nutrient, soil acidity, and the impact nitrogen source can have on the uptake of other essential nutrients. Let’s compare two nitrogen sources below:

Ammonium Nitrate YaraLiva Calcium Nitrate
Ammonium must convert to nitrate via soil microbes to become plant available   Immediately plant available  
Increases soil acidity   Does NOT increase soil acidity  
Competes with the uptake of other essential nutrients such as potassium, calcium and magnesium   Nitrate nitrogen in YaraLiva increases the uptake of potassium, calcium, and magnesium  
No calcium Includes 100% soluble calcium  

citrus growth stages

When considering a solid fall nutrition plan for citrus, be sure to include nitrogen, potassium, and calcium to:

  • Meet uptake demand to maximize fruit health and production.
  • Replace nutrients removed from harvest.
  • Meet uptake demand in preparation for spring flush.

YaraLiva® Calcium Nitrate provides nitrate nitrogen that is non-acid forming, gentle on the root system, enhances nutrient uptake, and is also a source of 100% soluble calcium. Calcium nitrate helps maintain soil pH and in-creases resistance to environmental stresses, such as heat, cold and salinity, while decreasing the amount of time it takes a young tree to become a profit-generating member of the citrus grove.

The calcium in YaraLiva also helps to:

  • Enhance citrus root, upper structure growth and overall tree health.
  • Build strong cell walls when cells are developing.
    • Strong cell walls increase resistance to bacteria and fungal infection because the pathogens cannot "digest" the cell wall.
    • Stronger cell walls increase the efficacy of other crop protection chemical treatments.

In summary, comparing ammonium nitrate to calcium nitrate is like comparing apples to oranges - they just aren't the same! Make the healthy choice for your grove this fall and ask for YaraLiva Calcium Nitrate in your dry and liquid fertilizer blends.
