It has become customary for farmers to use chemical fertilizers with water, but it is not appropriate to adopt this method at present. Because of the high temperatures in the summer, the large amount of ammonia volatilization reduces the energy efficiency when chemical fertilizers are used. Especially ammonium bicarbonate is more likely to cause eggplant ammonia poisoning. The use of trenching or digging is best, and the thickness of buried soil after top dressing should not be less than 5 cm. Eggplant requires the most amount of nitrogen, but in the hot season, it is necessary to eat less. Urea application per acre should generally be controlled within 30 kilograms. Because of the high temperature season, the transformation rate of urea is quicker after it is applied to the soil. After the plants meet their needs, the excess will be lost. In particular, sandy soils have a greater percentage of losses. Ammonium bicarbonate should not exceed 40 kg per acre. Excessive application rate will cause damage to the leaves and fruits of eggplant, in addition to the loss of nutrients. Eggplant can't be topdressed with nitrogen fertilizer every time in summer, and phosphorus and potash are indispensable. In the full fruit period, it is best to apply two compound fertilizers at a rate of not less than 40 kilograms per acre to meet the needs of eggplant growth and results.
