As one of the essential micronutrients required by plants, manganese plays an important role in wheat growth, development, and production. Deficiency of manganese in the wheat crop can result in slower growth, yellow or white streaks on leaves, and reduced yields. Therefore, it is crucial to correct the deficiency of manganese in the wheat crop to ensure optimal performance. Here are some steps to follow:
1. Soil Testing: Firstly, it is important to identify the severity of manganese deficiency in the soil. Soil testing is a preferred method to evaluate soil composition and nutrient levels. Soil test results will indicate the level of manganese in the soil in parts per million (ppm). If the results show low levels of manganese, it is important to take corrective measures.
2. Fertilizer Application: If low levels of manganese are identified in soil testing, the application of manganese fertilizers is a good option for addressing the deficiency. There are several types of manganese fertilizers available in the market. Manganese sulfate is the most commonly used fertilizer to address manganese deficiency. It is necessary to apply the recommended amount of fertilizer, as over-application can be detrimental to crop growth.
3. Soil pH Modification: Soil pH plays an important role in plant nutrition. Manganese is more available to plants in a soil pH range of 5.5 to 6.5. Soil pH levels that are too acidic or alkaline can decrease the availability of manganese to plants. If the soil pH is below 5.5, adding lime to raise the pH may increase manganese availability. Conversely, if the soil pH is above 6.5, sulfur or sulfur-containing fertilizers can be added to decrease soil pH levels.
4. Crop Rotation: Crop rotation is also an effective way to manage manganese deficiencies. Wheat plants that are grown in manganese-deficient soils may have reduced yields and impaired growth. Growing crops such as corn, sorghum, and soybeans can improve manganese levels in soil through a process known as mineralization. In the following wheat-growing season, the manganese levels in soil can be adequate enough to promote better growth and higher yields in the wheat crop.
In conclusion, correcting the deficiency of manganese in the wheat crop requires careful planning and implementation of the right strategies. A combination of soil testing, fertilizer application, pH modification, and crop rotation can help achieve the desired results. By correcting manganese deficiencies, farmers can improve their yields and contribute to food security.
