Preparation of the soil to obtain the best potatoes


Fertilizers and lime can be used to modify the chemical characteristics of the soil in a simple way. Changing the physical qualities of the terrain, on the other hand, can be extremely difficult, if not impossible. This is why field selection is so important (combining the physical properties of the field with the requirements of the crop).

Potatoes can only grow in well-drained soil and hate wet soil. They can spread more easily in thick, hard-packed, loamy soil that prevents plant roots from getting the air and water they need because they are making all their growing basements.

It has been found that proper soil preparation has a major impact on product homogeneity. In loose, loamy soil, potato plants can grow more efficiently. There are two approaches to improving the condition of your soil. First, the physical and chemical qualities of the soil affect crop productivity.

Let’s look at some more details about preparing the soil for seed potatoes.

Maintain soil pH

Potatoes require a little more attention as they are big feeders. Provide your potato plants with plenty of fertilizer and keep them nourished. While maintaining optimal soil pH is of the utmost importance, feeding the plant only fertilizer will not help. The ideal soil pH for potato production is between 5.0 and 6.0. In high pH soil, potatoes will survive blooms up to 4.5 and 8.0, but the crop will suffer.

Although phosphorus and other micronutrients are present in the soil, potatoes grown in soil with a pH of 7.5 or higher will experience phosphorus consumption and other micronutrient deficiencies. The use of phosphorus and molybdenum will be limited in acid soils with low pH, which will result in immature plants with yellow leaves.

Soil compost

Not only clay soils, but all soil types will benefit from compost. This is due to the presence of organic elements and nutrients in the compost. Compost improves soil structure while nourishing plants. In general, the higher the organic matter content, the higher the productivity of the soil. Therefore, efforts should be made to keep organic matter levels above 3%.

Organic matter improves soil structure, moisture, air, warmth and nutrient system, and minimizes the likelihood of soil erosion.

Making compost from yard and kitchen scraps, which you may already have, is the best part. Although compost and covered crops can help restore some soil nutrients, fertilizers are sometimes necessary. This is especially true if you are growing heavy feeder crops that require a lot of nutrients.
