What kind of soil is better for planting sweet potatoes

The best choice for planting sweet potato is sandy loam with loose air permeability, deep soil layer and good drainage. The requirements of sweet potato for soil are relatively high. Only such soil can meet the nutrient demand of sweet potato growth, and make the quality and yield of cultivated sweet potato reach a good level. The growth of sweet potatoes will be inhibited when they are planted in sticky, difficult to drain or poor soil. 1、 What kind of soil is better for planting sweet potatoes? Fertile soil with rich organic matter and deep soil layer is the most suitable for planting sweet potatoes. Fertile soil can provide sufficient nutrients for sweet potatoes to grow better.

Because the edible part of sweet potato grows underground, if it is planted in the soil with high viscosity and poor air permeability, it is easy to hinder the growth of sweet potato tubers. The size and shape of the final sweet potato will be affected. So plant with breathable soil.

In addition, the growth of sweet potato needs water, but the water needs to be kept within an appropriate range. In the continuous rainy weather, if the soil drainage is not good enough to cause ponding, the sweet potato is easy to rot. Therefore, the soil planted with sweet potato has better drainage. 2、 What kind of fertilizer is better for planting sweet potato 1. Base fertilizer: base fertilizer plays a positive and important role in the growth of sweet potato. The most suitable fertilizer as a base fertilizer is the fully decomposed organic farmyard fertilizer. It can not only provide continuous nutrients for the growth of sweet potato, but also imperceptibly change the soil condition.

2. Topdressing: it is necessary to use ternary compound fertilizer combined with organic farmyard fertilizer for topdressing during stem and leaf growth. After the photosynthesis of sweet potato leaves increases, more sugar will be provided to the roots, making the taste of sweet potato better. When the stem block begins to expand, the method of ditch application or hole application should be used to add nitrogen, phosphorus and potassium compound fertilizer.
