PREVENTING CALCIUM DEFICIENCY AND ESTABLISHING AN OPTIMAL CALCIUM-TO-BORON RATIO
Calcium is one of the nutrients that moves through the soil and is absorbed by plants primarily via mass flow. In other words, calcium availability and uptake are closely associated with the plant’s evapotranspiration (ET) rate and therefore depend largely on water movement through the plant.
Excessive irrigation, drought stress, high EC, low light intensity, strong winds, and high phosphorus levels are among the major factors affecting calcium uptake.
In orchards, greenhouses, and field crops, one of the main challenges is the mismatch between calcium uptake and the crop’s phenological stages. For example, if excessive irrigation is applied during the period of peak calcium demand, calcium deficiency may still occur.
Plant nutrition principles therefore emphasize that nutrients must be continuously available to the plant.
This is where the LEINR release mechanism can play an important role. In ROZHE, calcium and boron are incorporated using the LEINR technology, allowing the nutrient to be continuously and gradually released over a minimum period of 15 days, keeping it available to the plant roots.
Therefore, during periods of peak plant demand, increased transpiration generates mass flow from the soil solution toward the roots, facilitating calcium uptake precisely when the plant requires it most—during critical stages of growth and development.
Special Characteristics:
- Synergistic action of calcium and boron: Helps prevent disorders such as hollow heart in peanuts. In many cases, boron deficiency, by limiting calcium transport, can seriously impair cell division and cell wall development.
- Neutral pH: ROZHE’s fully neutral pH helps maintain calcium solubility, enhances boron uptake, and prevents reductions in the uptake of macronutrients.
- Calcium release synchronized with the plant’s peak demand
- Enhanced cell development and fruit quality: Boron is essential for the transport of water, nutrients, and photosynthetic sugars to rapidly growing tissues such as meristematic tissues. Its synergistic action with calcium promotes improved cell growth and development, resulting in better fruit size and shape uniformity.
