What kind of fertilizer is good for black bean base fertilizer (base fertilizer application method)

Black bean fertilizer effect

Base fertilizer is the nutrient basis for black beans in the early growth stage. It can meet the nutritional needs of black beans before flowering, and promote the emergence and growth of the seedlings as early as possible, which has a promoting effect on the growth of the plants.

Black bean fertilizer selection

Black bean base fertilizer can be farmyard manure, and organic fertilizer can be applied per mu, such as 1000-1500 kg of livestock and poultry manure, compost, and soil manure, and 30 kg of compound fertilizer containing nitrogen, phosphorus and potassium. After evenly spreading on the land, plow and harrow it to mix the base fertilizer and soil evenly.

How to apply black bean base fertilizer

Before sowing black beans, base fertilizer should be applied to the land after land preparation. The fertilizer must be fully decomposed and cannot be used directly.

If you want to ensure that you can harvest high-quality black beans in the later stage, you must make adequate preparations in the early stage. The first is to ensure that enough base fertilizer is applied. The base fertilizer should be applied according to the season. If base fertilizer is applied in spring, about 2,500 kilograms of farmyard manure can be applied per acre of land, and then a small amount of chemical fertilizer can be added.

In summer, you can apply some quick-acting organic fertilizers or chemical fertilizers, because the growth of black beans is relatively rapid at this time. After applying enough base fertilizer, the land needs to be further plowed so that the fertilizer applied to the soil can be better and more evenly mixed with the soil. It can also increase the air in the soil, allowing the seeds to germinate better.

How much black bean base fertilizer should be added

Black beans have a relatively large demand for fertilizer and need sufficient base fertilizer. Generally, about 1000-1500 kg of farmyard manure can be applied.

How to apply fertilizer to black beans
