Nutrient deficiencies in vegetable and summer fields and greenhouses are one of the most important factors in reducing the quality and quantity of the crop. Proper and timely use of agricultural fertilizers can compensate for these deficiencies and meet the nutritional needs of the plant at different stages of growth. Deficiencies of elements such as nitrogen, phosphorus, and potassium cause poor vegetative growth, reduced flowering and fruiting, and a loss of product flavor and color, while deficiencies of micronutrients such as iron, zinc, and manganese cause symptoms such as yellowing of leaves, flower drop, and reduced plant resistance to environmental stresses. Proper fertilizer management, while preventing the occurrence of these deficiencies, will increase yield, improve crop quality, strengthen the plant’s defense system, and maintain soil and environmental sustainability.
Nutrient deficiencies for vegetables and summer crops, including cabbage, eggplant, melon or watermelon, cucumber, celery, carrots, peppers, onions, lettuce, strawberries, tomatoes, and potatoes.
