Why is mixing high-phosphorus fertilizer with calcium incompatible? Is the fertilizer bad or is there a problem? First, farmers need to understand that phosphorus (P) is antagonistic or incompatible with calcium (Ca). When these two elements are mixed, they don't mix or coagulate, reducing their effectiveness. When they form a precipitate, this can be a problem when spraying. As far as I know, there are four types of calcium used for foliar application: 1. Liquid calcium, which is calcium-boron. Or add other elements. 2. Calcium Nitrate 15-0-0 3. Calcium Chelate EDTA (Synthetic Chelate) Otherwise, you'll encounter those who mix humic, phenolic, etc., claiming that I'm chelating too. 4. Calcium Chloride 27% The calcium that's used for foliar spraying and seed spraying at fertilizer and pesticide stores comes in two forms: regular and chelated. 1. Regular forms, such as liquid calcium, can be calcium, boron, calcium alone, or powder. This depends on which form of calcium the company uses. Some companies use calcium nitrate 15-0-0, some use calcium chloride, and some use calcium EDTA. It depends on which form of calcium the company uses. Honestly, you should ask the manufacturer, as it doesn't specify on the label. If you're using liquid calcium, I haven't seen the label specify which form of calcium is used. However, some companies will state that their products are in chelated form, but if they don't state this, it's probably not. Ask the seller or manufacturer what type of calcium they use to produce liquid calcium. 2. Calcium Chelate: Calcium in chelated form. Chelates encapsulate nutrients, preventing them from reacting with other environmental ions. Calcium, which has a positive charge, reacts with phosphorus, which has a negative charge, causing incompatibility, precipitation, and inhomogeneity. When purchasing foliar nutrients, it's important to understand the fertilizer form described. Also, note that each company's products differ, as each company has its own formula. If you use multiple brands, ask the seller if they can be mixed together. Each type of calcium 🌿 15-0-0 Calcium Nitrate + Ca 18% 🌿 Calcium Chloride 27% 🌿 Calcium EDTA 9% (Chelated Form) How are they different? First, let's learn about secondary nutrients: calcium. #Calcium is a secondary plant nutrient, in the same group as magnesium and sulfur. Calcium is essential for plant growth at all stages. A lack of calcium or insufficient calcium can lead to stunted growth, wilted shoots, leaf drop, and root system deterioration, ultimately leading to plant death. Calcium is beneficial to plants. ✅ Helps prevent breakage, leaf loss, or wrinkling. ✅ Prevents yellowing of leaves and cell wall deterioration. ✅ It is a major component of root cells, tissues, and plant cell walls. ✅ Aids plant growth, cell division, and hormone production. ✅ Strengthens flower cells, flower stalks, and pistils. ✅ Controls normal flower cell growth and expansion. ✅ Reduces flower drop and improves flower set. ✅ Resulting in better flower bloom and fruit set. ✅ Prevents fruit cracking and rot, helping maintain a beautiful shape. ✅ Helps produce vibrant fruit color. __________________________________________ 15-0-0 Calcium Nitrate + Ca 18% A fertilizer containing nitrogen in the form of nitrate. Plants can absorb it immediately, unlike urea fertilizer, which does not require the conversion of urea to ammonia, or nitrification. Nitrate accelerates new leaf development, leaf development, and root system development. It also helps to transport #calcium into plants, resulting in faster results after use. ***** Popularly used during the recovery stage - for early plant growth and hydroponic systems. __________________________________________ Calcium Chloride 27% This concentrated calcium fertilizer contains up to 27% calcium, with a concentration of over 90%. It is a food-grade product that is safe for plants and can help preserve the yield for a longer period after harvest. ***The #chloride or chlorine component found in calcium chloride may be a source of doubt and concern for many. Many people believe that this nutrient is salty and harmful to plants. However, chloride is actually an essential nutrient for plants. Although only needed in small amounts, it is essential because it plays a role in the production of plant enzymes. It helps keep plants green and reduces leaf wrinkling. Therefore, using the right amount of chloride will provide the most benefits to plants. It can be used by broadcasting, spraying, and mixing with drip or sprinkler systems. ***** Popularly used at all stages of plant growth. __________________________________________ Calcium Chelate EDTA 9% This calcium is a nutrient in chelated form. Although it contains a low percentage of nutrients, its unique feature is its nutrient fixation, allowing plants to absorb nutrients more completely, faster, and more efficiently. It is ideal for foliar spraying, as plants can absorb ...
