CAB PLUS
Fast-Acting Calcium and Boron Nutrition for Stronger Flowers, Fruit and Growing Tissues
CAB PLUS is a liquid calcium and boron deficiency corrector designed for rapid uptake through foliar or soil application. Its balanced supply of 12.0% w/v calcium oxide (CaO) and 1.24% w/v boron (B) supports cell-wall formation, flowering, fruit set and sugar transport towards developing organs.
By helping crops maintain an adequate Ca–B balance during periods of high demand, CAB PLUS contributes to firmer, better-quality produce and helps reduce the risk of physiological disorders associated with poor calcium or boron nutrition. It is suitable for horticultural crops, fruit trees, vines, tropical crops, field crops, turf and pastures.

Origin and Certifications
Part of Tangel Agro’s macronutrient range, CAB PLUS is marketed by a Spanish agricultural-input company that develops crop nutrition and bioprotection solutions for international agriculture.
The technical datasheet classifies CAB PLUS as a fertilizer, displays the CE mark and identifies the product as imported from the EU. The available documentation does not state that CAB PLUS is certified for organic farming. Registration, permitted uses and labelling requirements may differ between countries, so the local commercial label and applicable legislation must always be checked before use.

Features and Properties
The liquid formulation contains calcium oxide and boron and is intended for both foliar and soil use. Its declared composition is 12.0% w/v calcium oxide (CaO) and 1.24% w/v boron (B), with a density of 1.38 g/cc. This combination is designed for crops that require simultaneous support from two nutrients closely involved in the development of new tissues and reproductive organs.
Calcium contributes to cell-wall formation and the structural integrity of plant tissues. Adequate calcium nutrition is especially relevant in organs with rapid growth or low transpiration, including young leaves and developing fruit. CAB PLUS is therefore positioned for programmes aimed at supporting tissue firmness, fruit quality and the prevention of calcium-related physiological disorders.
Boron is involved in cellular activity, protein synthesis and sugar transport. Its role becomes particularly important around flowering, fertilisation and fruit set. Supplying boron alongside calcium allows growers to address two connected nutritional requirements within the same application programme.
The product can be applied over the canopy or delivered to the root zone by drip or localised irrigation. This flexibility allows the application method to be adapted to crop architecture, irrigation infrastructure and the stage at which nutritional support is required. CAB PLUS is supplied in 1 L, 5 L and 20 L plastic bottles, as well as 1,000 L IBC containers for larger-scale programmes.
Recommended Crops and Timing of Application
Horticultural Crops
Recommended horticultural crops include tomato, pepper, cucurbits, lettuce, strawberry, celery, cabbage and broccoli. In fruiting vegetables, applications can be positioned from pre-flowering to fruit set and early fruit enlargement. In leafy vegetables, target periods of rapid leaf development or conditions in which tipburn and other calcium-related disorders are likely to occur.
Fruit Trees and Vines
Apple, pear, peach, cherry, plum, citrus and grapes can benefit from Ca–B support around flowering, fruit set and early fruit growth. In apples, a preventive nutrition programme may help reduce the risk of bitter pit, cork spot, cracking, internal brown spot and watercore where these disorders are associated with inadequate calcium and boron nutrition.
Tropical Fruit Crops
The datasheet lists banana, pineapple, mango, durian, papaya, cocoa and guava. Apply during active growth and reproductive stages, particularly around flowering, fruit set and the beginning of fruit development, subject to the crop-specific local label.
Field Crops, Turf and Pastures
CAB PLUS is suitable for cotton, potato, sugar beet, rice, turf and pastures. Timing should coincide with active growth or crop stages with increased nutritional demand. In potatoes, nutrition should be managed preventively around tuber initiation and development when the objective is to support internal quality and skin set.
Physiological Disorders Targeted by the Nutrition Programme
According to the technical datasheet, CAB PLUS is intended to help manage the nutritional conditions associated with:
- Blossom-end rot or apical necrosis in tomato, pepper, eggplant and watermelon.
- Watercore and glassiness in melon.
- Internal leaf and curd defects in cauliflower.
- Internal browning in Brussels sprouts.
- Leaf tipburn in spinach, lettuce, celery, cabbage and strawberry.
- Internal browning, hollow heart, storage disorders and poor skin set in potato.
- Bitter pit, cork spot, cracking, internal brown spot and watercore in apple.
- Hypocotyl necrosis in beans and other legumes.
These disorders may also be influenced by irrigation, root health, climate, salinity and interactions with other nutrients. CAB PLUS should be used as part of an integrated crop nutrition and water-management programme rather than as a substitute for diagnosing and correcting the underlying cause.
FAQ
What is CAB PLUS?
CAB PLUS is a liquid calcium and boron deficiency corrector for foliar and soil application. It is formulated to support rapidly growing tissues, flowering, fruit set and fruit quality.
What is the composition of CAB PLUS?
The product contains 12.0% w/v calcium oxide (CaO) and 1.24% w/v boron (B). Its density is 1.38 g/cc.
Can CAB PLUS be applied by foliar spray and fertigation?
Yes. The technical datasheet provides for foliar application and soil application through drip or localised irrigation. Rates differ according to the crop group and application method.
When should CAB PLUS be applied?
Position applications before or during periods of high Ca–B demand: rapid vegetative growth, pre-flowering, flowering, fruit set and early fruit development. The exact timing and frequency should reflect crop monitoring and the locally approved label.
Does CAB PLUS prevent blossom-end rot?
By supplying calcium and boron, the product can form part of nutrition programmes designed to reduce the risk of blossom-end rot associated with inadequate nutrient availability. However, this disorder is also affected by water supply, root activity and growing conditions. Nutrition must therefore be combined with consistent irrigation and sound crop management.
Can CAB PLUS repair fruit or leaves that are already damaged?
Necrotic or structurally damaged tissue does not recover. Preventive use—or intervention at the earliest signs of nutritional imbalance—is the appropriate approach for protecting new growth and developing fruit.
How many applications are required?
The technical datasheet does not establish a fixed number or interval. Build the programme around crop demand, tissue or soil analysis, deficiency pressure and local label directions, preferably with guidance from a qualified agronomist.
Can CAB PLUS be mixed with other fertilizers or crop-protection products?
Compatibility depends on water quality, concentration and the products included in the tank. Check all applicable labels and perform a jar test before mixing. If compatibility is uncertain, apply the products separately.
Is CAB PLUS certified for organic farming?
The available technical datasheet does not state that CAB PLUS is certified for organic production. Confirm its status with the supplier and the certification body responsible for the destination market before using it in an organic programme.
