Calcium Nitrate for Apple
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 for 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.
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.
Nitrogen is the nutrient required in the greatest quantities. It is key for chlorophyll production, plays a major role in cell division, and supports growth of new tissues and roots. Calcium is directly related to fruit growth, cell division, and the overall strength and health of apples.
Applied pre-bloom in apples, calcium nitrate helps to strengthen fruit buds and improve fruit set. 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 an adequate supply of calcium nitrate are visibly healthier, more vibrant in color, and are blemish-free inside and out.
The addition of YaraLiva to an apple fertilizer program can help to increase bearing surface in varieties like Red Delicious and Honeycrisp. Applied post bloom, growers may see reduced internal bleeding issues.
Season after season, growers are faced with a variety of environmental stresses that are simply out of their control. While nature and weather will take their course, with YaraLiva Calcium Nitrate growers can give their and trees the strength needed to protect against diseases and environmental stresses such as heat and drought.
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.
