Mulching the soil after harvest is an effective method to protect crops against bacterial and fungal diseases



Soil mulching is an exceptionally effective method that offers numerous benefits to both plants and the ecosystem. It involves covering the soil's surface with a layer of organic plant material, such as straw, corn stalks, or forest litter. In agricultural practice, this technique is increasingly popular, and its effectiveness has been repeatedly confirmed by research.







The main advantage of mulching is the protection of the soil against unfavorable environmental conditions. The mulch layer acts as a cover, shielding the ground from excessive drying during hot weather and from erosion caused by raindrops. This ensures that water from rainfall is retained in the soil and does not flow over its surface, minimizing the risk of nutrient loss. Mulching directly affects the quality of arable land, regulates the quantity and quality of microorganisms in the soil, and maintains their biological balance.






What is soil mulching?



Mulching is a technique used in horticulture and agriculture, involving the application of various materials to the soil surface to enhance its properties. The primary objective is to protect the soil from adverse external factors and improve its structure and fertility. One benefit of mulching is reducing water evaporation from the soil surface. The mulch layer acts as a barrier that retains moisture in the ground, supporting more efficient water resource management. This is particularly crucial during dry and hot periods when plants' water requirements are highest.






Inhibiting weed growth and preventing erosion



Another significant advantage of mulching is the reduction of weed growth. The mulch layer limits the access of light to the soil, inhibiting the germination and development of weeds, thereby reducing competition for crops for resources and nutrients. Consequently, farmers can decrease the amount of chemicals used to control weeds, resulting in less environmental impact and lower production costs.






Additionally, mulching protects the soil against erosion. The mulch layer serves as a cover that shields the soil from rain or wind, preventing its degradation. Consequently, even during heavy rainfall or strong winds, the soil structure remains intact and the nutrients stay in place.






The impact of mulching on improving soil structure cannot be ignored. Organic materials used for mulching, such as straw or cut plants and natural stubble elements, provide valuable nutrients to the soil. Moreover, under the influence of biological processes occurring in the mulch layer, microorganisms are activated, further enhancing soil structure and fertility.






Mulching is increasingly valued in sustainable organic farming. It improves soil productivity and crop quality while reducing the negative impact of agricultural activities on the natural environment. Consequently, more farms worldwide are incorporating mulching as an integral element of sustainable land resource management.






Why is it worth mulching the soil?



Mulching the soil is highly beneficial for its health, crop growth, and disease resistance. By covering the earth's surface with a layer of mulch, excessive evaporation is prevented, maintaining appropriate humidity levels. This ensures easier access to water for plants, directly supporting healthy growth. Additionally, mulching limits weed growth by blocking light, essential for weed germination and development. This practice also improves and preserves beneficial microorganisms in the soil, reducing the risk of plant diseases. Maintaining the appropriate bacterial flora significantly lowers the incidence of fungal and bacterial diseases. Consequently, crops are healthy and strong, and do not compete with weeds for resources, positively impacting crop yield.






Soil Protection



An additional benefit of soil mulching is protection against erosion. Wind and rainfall can damage the soil, causing it to lose its structure and nutrients. The mulch layer serves as a cover, protecting the soil from these external factors and helping to preserve its value. Furthermore, organic materials used for soil mulching provide valuable nutrients and stimulate the activity of microorganisms that positively affect the soil structure.






In practice, various mulching methods exist, each offering distinct advantages. Organic mulch, such as straw or compost, is often selected for its nutrient provision and soil structure improvement. However, it is essential to regularly replace the mulch. Excessive use of bark, for instance, can disrupt the mineral balance. Foil mulch, composed of special foils, targets soil protection against water loss and weed growth. The choice between methods depends on individual needs and growing conditions.






Rolmako - Superior Mulching Machines



Mulching the soil significantly enhances its health and structure. Key benefits of mulching include preventing soil erosion, retaining ground moisture, improving structure, and providing essential nutrients. This increases soil fertility and facilitates better nutrient access for crops.






In practice, mulching is performed using specialized agricultural machinery. One notable manufacturer of such equipment is Rolmako, which provides various types of mulching harrows. These harrows feature double working fingers of appropriate thickness and length, placed on solid pipes. The components are hydraulically adjustable, enabling the adjustment of their working angle to suit specific tasks.






The primary feature of the mulching harrow offered by Rolmako is its versatility. This machine operates at speeds up to 25 km/h, enabling efficient and rapid mulching of extensive areas. Additionally, optional cutting discs or rollers provide enhanced precision and ensure soil aeration.






In the context of environmental protection, mulching is advantageous for reducing chemical usage. By effectively eliminating weeds and crop residues, the necessity for herbicides is diminished, thereby lowering environmental impact. Mulching can be efficiently executed using machines designed for ultra-shallow cultivation, such as the SpeedCutter disc harrow.






Mulching fields with specialized Rolmako machines, including rotary harrows, significantly benefits soil health by improving its structure and enhancing the efficiency of plant cultivation. A rotary harrow is an effective tool for managing crop residues as its design and rotary mechanism facilitate even distribution of plant material on the field. This uniform distribution helps protect the soil from erosion and maintains moisture, which is particularly advantageous in sustainable agriculture.






The knife roller serves as an efficient alternative to a mulcher, offering faster and more effective vegetation cutting. Its blades are designed for precise cutting, providing better control over the cutting process. Additionally, a knife roller is often more durable and requires less maintenance compared to a mulcher, making it a more economical long-term choice. The knife roller is effective for shredding stubble and remains of corn, rapeseed, sunflower, and catch crops.
