What are the causes of nutrient deficiency in loofah and what are the preventive measures?

In the cultivation and management of loofah, various reasons such as watering and fertilizing often lead to a lack of trace elements in the plants, which causes the plants' growth to decline and affects both yield and quality. So what are the causes of nutrient deficiency in loofah? Let's take a look together.

1. Causes of iron deficiency

When the soil is alkaline, too dry or fruiting, or when the temperature is too low or copper, manganese, phosphorus and other elements are excessive, the root system's absorption of iron is affected, thus causing iron deficiency in the plants. Therefore, the soil should be kept moist to avoid it being too dry or too wet, and the application of alkaline fertilizers should also be controlled. When the plants are deficient in iron, a 0.1-0.5% ferrous sulfate aqueous solution can be sprayed on the leaves in time, which can quickly restore the plants from iron deficiency symptoms.

2. Causes of zinc deficiency

When the soil is alkaline, excessive zinc content prevents the root system from absorbing it, and too strong light intensity can also easily lead to zinc deficiency, while too much phosphate fertilizer also affects the absorption of zinc. Therefore, do not apply excessive phosphorus. If zinc is deficient, a 0.1-0.2% zinc sulfate aqueous solution can be sprayed on the leaves.

3. Causes of copper deficiency

The main cause of copper deficiency is alkaline soil or soil salinization, which seriously hinders the root system's absorption of copper. Therefore, when the soil is alkaline, acidic fertilizers can be applied to neutralize the soil, and at the same time a 0.03% copper sulfate aqueous solution can be sprayed on the leaves, which can very well alleviate the copper deficiency symptoms of the plants.

4. Causes of boron deficiency

Soil drought, alkalinity, poor fertility, and excessive application of potassium fertilizer all affect the absorption of boron. Water should be applied in a timely manner, organic fertilizer should be increased, and the level of soil fertility should be raised. At the same time, potassium fertilizer can also be increased; an appropriate amount of potassium fertilizer can be added to the base fertilizer, or a 0.12-0.25% boric acid or borax aqueous solution can be sprayed on the leaves during the middle and late stages of plant growth.

5. Causes of manganese deficiency

Reasons such as low soil organic matter content, alkalinity, and high salt concentration can all easily lead to manganese deficiency. Therefore, chemical fertilizers should be applied scientifically, and do not apply only chemical fertilizers, which causes excessive soil concentration. Pay attention to increasing the application of organic fertilizers, increasing soil organic matter content, and improving soil vitality.
