Your Grove's Success Depends on Balanced, Complete Nutrition
8 reasons why YaraLiva® Calcium Nitrate needs to be part of your citrus fertility program
Protect Against Crop Stresses
Season after season, growers are faced with a variety of crop stresses that are simply out of the industries' control. While nature and weather will take their course, with YaraLiva Calcium Nitrate growers can give their plants and trees the strength needed to protect against diseases and environmental stresses such as heat, drought, salinity and excessive sodium.
1. Drought stress
Crops suffering from water stress are damaged by Reactive Oxygen Species (ROS) such as hydrogen peroxide (H2O2) and the oxide ion (O2-) that form in response to stress. These ROS compounds damage plant membranes, proteins, and RNA and DNA. Calcium reduces the concentration and activity of these ROS compounds and thereby reduces the damage from water stress.
2. Heat stress
Heat stress damages plants by what is called “oxidative stress” which is due to the production of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) and the oxide ion (O2-). These ROS compounds damage plant membranes, proteins, and RNA and DNA. Calcium application help reduce the formation of these two key ROS species and the damage from heat stress.
3. Salt mitigation
Sodium suppresses root growth and calcium helps crop roots overcome the sodium damage. Increasing calcium supply increased root growth at both low and high sodium concentration.
4. Plant uptake
Soil microbes immobilize N from urea and ammoniacal sources. This renders the nitrogen unavailable to the plant to a large extent. Nitrate is the only nitrogen form that is 100% plant available.
5. Water balance
Soluble calcium improves soil structure by supporting aggregation and allowing for improved water infiltration. This increases soils’ water storage capacity and improves plant availability.
6. Nutrient availability
Nitrate, being an anion, attracts positively charged cations and helps support plant uptake of additional elements required for optimal plant and crop development.
7. Root health
Calcium is involved in many physiological functions including water regulation and stress signaling. Calcium is responsible for sending drought signals from the roots to the upper canopy of the trees which causes the stomata on the leaves to close. Plants required a continuous supply of calcium for root growth. Nut roots do poorly in soils with low levels of calcium. A better root system means better access to nutrients and water.
8. Soil health
Calcium nitrate improves soil bacteria abundance while other N sources reduce populations through acidification of the rhizosphere.
Fast Delivery of Critical Nutrients
Calcium is key throughout the life of the plant, right through to harvest. Roots need calcium for growth and a consistent supply is directly related to early fruit growth, healthy cell division, and the overall strength and health of fruits and vegetables. Alongside potassium, nitrogen is the plant nutrient required in greatest quantities. Nitrogen is key for chlorophyll production and plays a major role in cell division, growth of new tissues and root system development.
The preferred form of nitrogen for plant uptake is nitrate, and plants can be susceptible to ammonium-nitrogen toxicity especially in cool wet soils. Higher plants, including many fruit and vegetable species, are especially sensitive to ammonium. Nitrogen sources in the form of urea or ammonium take time to convert to nitrate in the soil, leaving plants vulnerable. With fully soluble calcium and nitrate-nitrogen, YaraLiva products guarantee these critical nutrients are quickly and efficiently available to crops.
Citrus roots, calcium deficiency on the right. A better root system means more access to nutrients.

$16K per Acre Accumulated ROI
In tree crops, it takes time before changes in the nitrogen regime become visible, but it pays off. This trial shows that calcium nitrate provided higher yields in the long term, with a $16,000/acre accumulated ROI.
Calcium Helps Maintain Citrus Yield Over Time
Calcium is critical for keeping tree vitality to maintain yield over time as demonstrated by this long-term trial in Florida.
Calcium Nitrate Provides Higher Nitrogen Efficiency
120 lb N/ac of calcium nitrate provided the same yields (t/ac) and solids (lb/ac) as with 160 lb N/ac of ammonium nitrate.
Don't miss your chance
To give the plant strength and fuel to grow during this stressful time of the year, 20% of total N should be applied as YaraTera NITRAKAL or YaraLiva TROPICOTE. Growers need to provide adequate nutritional programs to supply critical nutrients. Calcium will be needed for structure replacement, the upcoming fruit crop and to maintain the tree in optimum health to resist diseases. The most effective way for a citrus grower to supply calcium is through application of soluble calcium. YaraLiva TROPICOTE or YaraTera NITRAKAL Liquid Calcium Nitrate provide both soluble calcium and nitrogen for immediate uptake and optimum performance producing maximum profits.
