Valagro Calbit C Micronutrient (Calcium Oxide 15%) is a liquid calcium-based nutritional supplement developed to help prevent and correct calcium deficiency in agricultural and horticultural crops. It contains water-soluble Calcium Oxide (CaO) 15% complexed with Valagro's LSA technology for efficient calcium availability and movement within treated plants.
Calbit C promotes the rapid translocation of calcium toward actively developing plant tissues, particularly fruits and flowers. Adequate calcium nutrition supports cell-wall strength, fruit firmness, quality and post-harvest keeping ability while helping reduce physiological disorders associated with calcium deficiency.

Blossom-end rot in tomato is commonly associated with inadequate calcium reaching rapidly developing fruit tissues. The condition typically appears as a dark, sunken area around the blossom end of the fruit.
Calbit C supplies complexed calcium and supports movement of calcium toward developing fruits. Calcium management should also include consistent irrigation, healthy root development and balanced crop nutrition.
Bitter pit is a physiological disorder of apples associated with inadequate calcium concentration in fruit tissues. Symptoms may appear as small sunken spots that affect fruit appearance, quality and storage characteristics.
Regular calcium supplementation during fruit development can support fruit calcium status. Valagro specifically identifies Calbit C for prevention and treatment of calcium-related bitter pit problems in apples.
Tip burn in lettuce and related leafy vegetables can occur when rapidly developing leaf tissues receive insufficient calcium. It commonly affects young internal leaves even when calcium is present in the soil.
Foliar calcium supplementation with Calbit C can form part of a crop-management program aimed at improving calcium availability to actively growing tissues.
Valagro identifies Calbit C for supporting the management of calcium-related fruit cracking in crops such as cherries, peaches, nectarines and plums.
Calcium contributes to structural strength of plant cell walls. Maintaining adequate calcium nutrition can therefore support stronger fruit tissues, although cracking can also be influenced by irrigation, rainfall, variety and environmental conditions.
Calcium is an essential plant nutrient with an important structural role in cell walls and cell membranes. Adequate calcium nutrition supports strong growing tissues, fruit firmness and normal development of young leaves, roots, flowers and fruits.
Calcium has limited mobility within many plant tissues, which means rapidly growing organs can develop deficiency symptoms even when soil calcium levels appear adequate. Targeted foliar or fertigation supplementation can therefore be useful during periods of rapid crop development.
Calbit C uses an LSA complexing system to improve the availability and movement of calcium. The complex helps protect calcium from certain insolubilisation reactions, which can improve its suitability for fertigation.
Valagro states that the LSA-calcium complex remains stable within approximately pH 3 to 6.5, supporting calcium availability under suitable application conditions.
Calcium is important for maintaining structural integrity in fruit tissues. Calbit C applications are intended to support improved fruit firmness and consequently may help maintain produce quality during handling and storage.
Actual post-harvest performance also depends on variety, maturity, growing conditions, irrigation, disease management and storage practices.
Calbit C can be used according to label recommendations across a wide range of agricultural and horticultural crops, including:
| Crop Group | Application Timing | Reference Dose |
|---|---|---|
| Fruit Crops | Every 7–10 days from flowering through fruit development as required | 2–3 L/ha |
| Vegetables | Every 7–10 days from flowering through fruit development as required | 2–3 L/ha |
| Ornamentals & Leafy Vegetables | 2–3 applications according to crop need | 250–350 ml per 100 L water |
The rates above are Valagro global catalogue reference rates. Local crop recommendations and the current product label should be followed for final application rate, interval and spray-water volume.
| Application Method | Crop | Reference Dose |
|---|---|---|
| Fertigation | Label-Recommended Crops | 10–30 L/ha per application |
The required fertigation rate depends on crop type, crop stage, calcium requirement, growing medium, water quality and existing nutrient program. Follow local label recommendations before application.
Calcium demand is often high during periods of rapid vegetative growth, flowering, fruit set and fruit enlargement. Foliar applications are commonly scheduled from flowering through fruit development where calcium deficiency risk is present.
Application timing should be adjusted according to crop condition, tissue analysis, local growing conditions and label recommendations.
Valagro states that Calbit C is miscible with many commonly used pesticides. However, compatibility can vary according to formulation, water quality and tank-mix partner.
