What crops are suitable for growing on clay soil?

Clay soil is generally formed by the weathering of acid salt minerals. The proportion of clay particles in the soil is very high, the viscosity is high, and the air permeability is poor, but the ability to retain water and fertilizer is very good. Crops suitable for planting here generally like moisture or aquatic environments.

There are many crops that can be grown on clay soil, the most common ones include rice, lotus root, calamus, water hyacinth, arrowhead, water spinach, water celery, water chestnut, Houttuynia cordata, taro, water chestnut, purple taro, etc.

1. Horseshoe

Water chestnut can also be planted in clay soil. It prefers a warm and humid environment, but is not tolerant to deep water. The water level should be around 5-10 cm. During maintenance, pay attention to regular fertilization and manual weeding.

If you want to plant water chestnuts in clay soil, it is best to deep plow several times before planting. The plant has high requirements for water and must be strictly prevented from drought during the entire growing period. The ambient temperature should be controlled above 15°C. During the seedling stage, shallow water should be used frequently.

2. Lotus root

Lotus root is a typical aquatic vegetable and can also be grown in clay soil, but the soil must not be allowed to lack water. The plant cannot lack water throughout the entire growing period and has very high requirements for nutrients. Just follow the principle of "applying small amounts of fertilizer frequently."

3. Green onions

Green onions do not have high requirements for soil and can adapt to most soil types. They can grow in sandy soil, clay, loam and other places, but green onions grown in loam have the best quality.

In comparison, although the green onions grown in sandy soil have longer white parts, the white parts are loose in texture, less hard, have a rough taste and are not durable in storage.

Although the green onions grown in clay soil have firm and hard whites and tender and crispy flesh, the whites are generally shorter.
