Calcium Nitrate for Fruits and Vegetables
Yara's comprehensive range of calcium nitrate fertilizers that help ensure high-value, highly marketable produce, is called YaraLiva®.
YaraLiva calcium nitrates provide fast-acting nitrate-N, alongside strength-building calcium. In combination, these nutrients fuel prolonged growth. Plants and trees treated with YaraLiva-branded fertilizers are naturally healthier and less sensitive to stress during growth. Then, critically, in the build-up to harvest, YaraLiva calcium nitrate fertilizers improve the size, strength and appearance of the fruits and vegetables.
The YaraLiva formulation includes nitrates, the preferred N form. Crops respond more quickly to nitrate. It is also more mobile in the soil and immediately available to the crop.
By using YaraLiva fertilizers you will get a longer-lasting fruit and vegetable with improved inner health and outer beauty.
Calcium is key throughout the life of the plant. 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, vegetables and nut crops.
Nitrogen is the plant nutrient required in the greatest quantities. It 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 N for plant uptake is nitrate. With fully soluble calcium and nitrate-nitrogen, YaraLiva products guarantee these critical nutrients are quickly and efficiently available to crops.
With the strengthening of cell structure and protection against stresses, fruits and vegetables with a healthy supply of calcium nitrate are visibly healthier, more vibrant in color and are blemish-free inside and out. When YaraLiva is included in a fertilizer program, fruit and vegetables also keep their weight and quality for a longer time period; keeping them fresh until enjoyed by consumers.
Season after season, growers are faced with a variety of environmental stresses that are simply out of the industries' control. While nature and weather will take its 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.
Calcium is an essential component in maintaining the cell wall structure of a plant. Inadequate availability of calcium can increase the susceptibility to diseases.
The effectiveness of calcium lies in its solubility. Some common sources of Ca fertilizer are not soluble, therefore are not taken up by the plants. YaraLiva Calcium Nitrate provides readily available calcium for optimal plant uptake.
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.
Not all nitrogen sources are the same. Research shows that calcium nitrate has a significantly better effect on root development than ammonium nitrate.
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.
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.
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.
Research has shown that calcium helps suppress the uptake of sodium. Excessive sodium limits root development.
