Optimal Timing and Benefits of Autumn Mustard Sowing as a Green Manure

Organic farming is becoming increasingly popular among homeowners, particularly due to the reduction in the use of chemical plant protection products and synthetic fertilizers. One of the key elements of this approach is the use of green manures, among which mustard holds a leading position due to its unique properties.

Benefits of Using Mustard as a Green Manure

Mustard is characterized by rapid germination and vigorous growth: its growing season lasts only 30-45 days. The crop is resistant to diseases and pests, which helps to “cleanse” the soil and attract bees to the area. The advantages of growing mustard as a green manure include:

• Increased soil fertility without additional fertilizer application.
• Protection of the soil from erosion and drying out.
• Improvement of soil structure and aeration.
• Creation of a favorable environment for the development of beneficial microflora due to plant residues.
• Repelling pests thanks to the essential oils in the plant.
• Reduction of weed growth in the area.
• Importance for beekeeping, as mustard is a valuable honey plant.
• Contributing to crop rotation practices.

Sowing green manure is quite economical — 200 to 400 grams of seeds are needed per 100 square meters.

Timing and Features of Sowing Mustard in Autumn

Mustard can be sown as a green manure both in spring and autumn. Spring sowing begins in the second half of March and continues until mid-September, using the winter method. It is often sown after harvesting the main crops, except for cabbage.

Autumn sowing of mustard is recommended from mid-August to mid-September, with the optimal time being late August. This allows the plant to form sufficient green mass before the cold weather arrives.

The sowing rate of mustard depends on the characteristics of the area, but on average, it is 300-350 grams of seeds per 100 square meters or about 4 kilograms per hectare. It is worth noting that the shelf life of the seeds is limited to three years, and their viability decreases each year.

Mustard is usually sown in autumn after harvesting the main agricultural crops. The preparation of the area involves several stages:

• Thorough loosening of the soil.
• Planting seeds at a depth of 7 cm, with a row spacing of at least 15 cm.
• Lightly covering the seeds with soil using a rake.
• Moderate watering after sowing.

After the mustard matures, the green manure can either be spread across the area or incorporated into the soil with a cultivator — both approaches are considered effective for enriching the soil.
