Proper application methods of foliar fertilizer for tomatoes
How should foliar fertilizer be applied to tomatoes? Please explain how to guide the timely spraying of calcium fertilizer on the leaves. Tomato fruit growth requires a relatively large amount of calcium, and when the soil supply of calcium is insufficient, the fruit is prone to blossom-end rot. Therefore, during the fruiting period of tomatoes, calcium chloride, superphosphate, amino acid calcium, calcium supplement preparations, etc. should be sprayed to meet the tomato's need for calcium...
How should foliar fertilizer be applied to tomatoes? Please explain the guidance
Spray calcium fertilizer on the leaves in a timely manner. Tomato fruit growth requires a relatively large amount of calcium, and when the soil supply of calcium is insufficient, the fruit is prone to blossom-end rot. Therefore, during the fruiting period of tomatoes, calcium chloride, superphosphate, amino acid calcium, calcium supplement preparations, etc. should be sprayed to meet the tomato's need for calcium. The interval between foliar fertilizer applications on tomatoes should be appropriate; the suitable interval for foliar fertilizer application on tomatoes is 5-7 days. When spraying inorganic chemical fertilizers on the leaves, fertilizer damage is likely to occur, so the interval should be longer, generally no shorter than 7 days. The interval for spraying organic nutrient fertilizers can be appropriately shorter, generally around 5 days is suitable. Foliar fertilizer should be applied in an appropriate amount. When leaf damage occurs, rinse off the excess fertilizer with clean water and increase the water content of the leaves to alleviate the degree of leaf damage. When the soil water content is insufficient, watering is also necessary to increase the water content in the plant body and reduce the concentration of the fertilizer solution in the stems and leaves.
