Apples have a high demand for nitrogen very early in the season. Nitrogen uptake starts at bud break and peaks at full bloom where a sustained amount is needed till harvest.
Applying YaraLiva calcium nitrate prior to bloom at the right rate is critical for tree health and longevity, fruit yield and quality, and your profitability.
Apple tree uptake and utilization of nitrogen start early – during the pollination and fruit set period. It is critical that the plant have nutrients in the correct amount and form to reach maximum yield and quality potential.
Apple trees prefer N in the nitrate form. The nitrate-N supplied by YaraLiva fertilizers is available fo plant uptake and enhances the uptake of other important nutrients such as calcium, magnesium and potassium.
Calcium plays a critical role in cell division and cell wall strength, and plasma membrane control of nutrient and water uptake. These processes are all dependent upon having a plant-available, soluble calcium fertilizer source that continually feeds the plant. Without calcium, plant health and crop quality are greatly compromised.
Apples, just like many fruits and vegetables, have a narrow window fro Ca uptake. Since calcium is taken up with water through the roots, high solubility of the calcium source is essential. Calcium Nitrate is an important tool for growers due to its solubility compared with other calcium soil amendments. Insoluble calcium sources will not provide adequate calcium fertility during critical uptake periods.
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 permanent 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, crops 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, fruits 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 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.
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. 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.
