How to apply base fertilizer to the corps?

What is base fertilizer?

• Base fertilizer, also called fundamental/primer fertilizer, is generally a slow-acting fertilizer, which is applied before sowing or transplanting, or at the end or beginning of each growing season for perennial crops.
• Base fertilizer is mainly related to tree vigor and age. Base fertilizer is usually required to be long-lasting, nutritious, and large in dosage. The purpose is to provide a comprehensive and gentle nutritional environment for the entire growth process of the plant.
• Base fertilizer can be divided into organic base fertilizer, inorganic base fertilizer and compound base fertilizer.

How many days does base fertilizer become effective?

• It takes about a week after the base fertilizer is applied before vegetables can be planted. The application of base fertilizer is a basic link in fertilization work and is crucial to the growth and development of crops. In general, base fertilizer should be applied within the entire tillage layer, that is, at a depth of 15-20cm.
• For organic fertilizers, nitrogen fertilizers, and micro-fertilizers, they can be mixed and spread evenly on the surface, and then plowed into the soil. Cake fertilizer is also suitable as a base fertilizer for the soil. Usually, bean cakes, peanut cakes, hemp cakes and other cakes can be mashed and put into an appropriate amount of rice washing water, and then placed in a cool place for fermentation.

How much compound fertilizer should be used as base fertilizer?

• How much compound fertilizer should be used as base fertilizer depends on the crop. Potato base fertilizer can use 50 kilograms of potassium sulfate compound fertilizer per acre, and add 4-6 kilograms of high-quality decomposed farmyard manure, 80-160 kilograms of organic fertilizer, and 50 kilograms of medium and trace element fertilizers. 
• For plots that have not been planted with potatoes or plots with low phosphorus, 25 kilograms of diammonium per acre can be added.

What are the precautions while applying base fertilizer?

• When fertilizing crops, you must pay attention to fertilizing according to time and location.
• Generally, fertilizing is done according to the demand for fertilizer at each growth stage of the crop. But sometimes there are special circumstances, such as crop seedlings growing too slowly.
• In this case, more fertilizer can be applied to them. If the soil fertility is insufficient and relatively poor, additional fertilizer can also be applied. When applying fertilizer, be careful not to get it too close to the roots of crops to prevent crop seedlings from being burned.
• Chemical fertilizers such as urea and compound fertilizer must be covered with soil after spreading, otherwise the fertility will be weakened.

What is base fertilizer top dressing?

• Fertilizer Top dressing refers to fertilizers applied to supplement or regulate plant nutrition during plant growth,typically aftert the application of base fertilizer.
• The main purpose of top dressing is to meet the nutrient needs of the plant during the growth period, especially when the base fertilizer is not enough to support the plant throughout the growth period.
• Top dressing usually uses quick-acting fertilizers, such as water-soluble fertilizers, which can be applied flexibly and adjusted according to different stages of crop growth and nutrient needs.

What are the precautions while applying top dressing base fertilizer?

• Although top dressing is generally applied directly by spreading fertilizer, if the top dressing is mainly nitrogen fertilizer, the superficial soil will be too shallow, which will lead to a large amount of fertilizer loss and the effect of top dressing will be relatively poor.
• Therefore, when applying fertilizer, be sure to cover it with soil and apply it deeply, and avoid applying fertilizer shallowly, openly, or with water.
• When topdressing, you should also look at the ground and seedlings for topdressing. For low-lying and alkaline lands, acidic or physiologically acidic fertilizers such as ammonium nitrate, ammonium sulfate, and superphosphate should be used for topdressing.
• For sandy loam soils with poor water and fertilizer retention capabilities, non-volatile fertilizers should be used. Ammonium nitrate or urea is used as top dressing.
