Features and Characteristics:
Agroton Cal Mag is a fertilizer compound that contains a balanced concentration of calcium (71) and magnesium (46.3), which can be used to support plants through foliar spraying during various physiological stages, such as pre-flowering, to strengthen field crops, vegetables, and fruit orchards. Magnesium is one of the essential elements that significantly contributes to the synthesis of chlorophyll and improves the efficiency and speed of photosynthesis, providing the plant with abundant energy and nutrients during vegetative growth stages that precede flowering. This prepares the plant for strong entry into the flowering and fruit-setting stages, which consequently increases both fruit setting and yield.
Calcium works alongside magnesium as it plays a vital role in several metabolic processes at the cellular and tissue levels in plants. Storing optimal levels of calcium within plant cells is crucial to meet the plant's needs during critical periods following flowering, fruit setting, and ripening.
Agroton Cal Mag contains calcium at an optimal concentration, which is an essential nutrient involved in the formation of calcium pectate. This compound gives plant tissues and cells structural support, flexibility, and elasticity, making them more resistant to piercing-sucking insects.
There are several symptoms of calcium deficiency in plants, such as:
- The first is known as the splitting phenomenon or fruit cracking in citrus fruits. This occurs due to the inability of the fruit peel to withstand internal pressure caused by the increased filling of juice sacs in segments after irrigation and water absorption. This leads to strong internal pressure, causing cracking. The peel appears as alternating waves of weak and strong cells, making it less marketable.
- Another symptom of calcium deficiency is the bitter pit in apples, which is the death and atrophy of the terminal ends of apple fruits due to a lack of calcium pectate.
- Common symptoms also include blossom end rot in zucchini or blossom-end scab in tomatoes, as well as the black stem phenomenon in grape clusters.
- In cereal crops such as wheat and rice, farmers often face the lodging phenomenon, which leads to grain loss on the soil, making it difficult for harvest machinery to gather, resulting in increased costs for farmers.
One of the most significant symptoms of calcium deficiency is the increased drop rate of set fruits, either physiologically or due to unfavorable climatic conditions. This is due to the weakness of the fruit's connection to the peduncle, causing fruit drop at the separation point, which leads to substantial crop losses. To prevent this, it is recommended to support plants and fruit trees with successive doses of foliar calcium sprays.
Agroton Cal Mag is a high-quality fertilizer, manufactured with global expertise from premium raw materials that are 100% water-soluble. It is also free from impurities, chlorine, and harmful heavy metals. The product is uniquely capable of causing significant improvements in vegetative growth due to its high magnesium content, as well as enhancing fruit quality and yield. The positive results of spraying can be observed rapidly in the early stages of plant growth.
Since calcium is an immobile element, it must be applied through repeated foliar sprays at close intervals to ensure that deficiency symptoms do not appear, preventing the previously mentioned damages.
Agroton Cal Mag is suitable for foliar spraying on all field crops, including those from the grass family such as wheat, corn, and rice, as well as root crops like sugar beet, taro, and sweet potatoes. It is also effective for legume crops such as peanuts, broad beans, peas, and beans, as well as onion, garlic, and sunflower.
The product is equally effective for vegetable crops, including solanaceous crops such as tomatoes, potatoes, eggplants, and peppers, and cucurbit crops such as cucumbers, zucchini, watermelon, and cantaloupe. It is also suitable for strawberries and fruit trees such as apple and pear (pome fruits), stone fruits like peaches, apricots, and plums, and other fruits such as grapes, citrus, olives, mangoes, and avocados. Additionally, it helps reduce the black stem phenomenon in grapes and other crops.
Application Rates and Uses:
Agroton Cal Mag is applied through foliar spraying as a preventive support before the appearance of deficiency symptoms on field crops, vegetables, and fruit trees. This is because correcting these symptoms becomes challenging once they appear. Therefore, it is advisable to apply calcium and magnesium preventively using Agroton Cal Mag or to spray it promptly at the first signs of deficiency symptoms as previously explained.
In general, the product is used at a rate of 1 liter per acre for field crops to reduce the lodging phenomenon in wheat and rice and for vegetable crops to decrease the likelihood of blossom end rot in zucchini or blossom-end scab in tomatoes.
For fruit trees, it is recommended to apply the spray at a rate of 150 ml per 100 liters of water. Two successive sprays are advised with a one-month interval between them:
- The first spray should be preparatory at the beginning of vegetative growth to support the plant with the magnesium available in Agroton Cal Mag.
- The second spray should be applied immediately after fruit setting to fully address deficiency symptoms without causing any setbacks to the plant's physiological processes.
Available Packaging:
Agroton Cal Mag is available in 1-liter and 5-liter bottles.
