Recipe for Heavy Soils - Agricultural and Agrotechnical Measures in the Cultivation of Heavy Soils

There are various types and subtypes of soil based on fertility. A distinction also exists between land and its weight. In Poland, many farms face challenges with cultivation on heavy soils, which necessitate a specific approach. Heavy soils, such as clay soils, constitute a significant part of the agricultural landscape. They are characterized by unique physical and chemical properties that require special attention during cultivation and care. Understanding the quality and type of soil and implementing appropriate agrotechnical treatments with the best agricultural machinery significantly improves the quality of cultivation on heavy soils. An appropriate approach makes effective cultivation possible even on heavy soils.

Characteristics of Heavy Soils

Heavy soils, such as clay soils, are characterized by greater moisture and adsorption capacity compared to other types of soils. They also contain a higher amount of humic compounds, which contributes to their fertility. However, the main drawback of these soils is the lack of oxygen, especially during periods of excess moisture. Additionally, they are characterized by high compactness and resistance during agricultural work, both in conditions of water deficiency and excess. A problem with heavy soils is also the spring waterlogging in the fields.

Heavy soils, primarily composed of clay, exhibit characteristics that impede plant growth. The primary issues are inadequate air and water permeability. In low rainfall conditions, these soils can become extremely dry, whereas during rainy periods, they may remain excessively saturated with water for prolonged durations. Additionally, on sunny days, they may heat poorly, further complicating plant metabolic processes.

To enhance the conditions of heavy soils and ensure proper plant growth, appropriate agrotechnical measures and agricultural machinery are necessary.

Mechanical tillage, such as harrowing, loosens and breaks up clay lumps, facilitating root penetration and enhancing soil drainage. Specialized machines, like deep cultivators and subsoilers, effectively improve heavy soil structure. These devices penetrate the soil deeply, loosening compact layers and increasing permeability.

Many farmers encounter issues with water accumulation on their land in spring, leading to seepage and standing water. This situation often delays the commencement of spring fieldwork and adversely impacts the crops.

Entering the fields with machines is unfeasible. Attempting this with lower levels of residual water results in deep, undesirable ruts during cultivation. Many machines become immobilized in the fields. Annually, due to climate change, this issue is intensifying, affecting not only heavy soils.

An innovative solution supported and developed by Rolmako involves machines mounted on the front three-point linkage of the tractor. This approach is not only economical but also highly effective for spring work on heavy soils.

Machines for the front three-point linkage of the tractor - balanced load and parallelization of agricultural operations

Agricultural machines mounted on the tractor's front three-point linkage evenly distribute the tractor's weight, reducing pressure on the rear wheels. Utilizing machines mounted simultaneously on both the front and rear three-point linkages enhances the cultivation process's speed and efficiency while minimizing ruts and unevenness in the field.

Rolmako's portfolio includes numerous tillage machines assembled in this manner. Of particular interest are the Crosskill roller, disc harrow, ProCut knife roller, and tillage cultivator.

Specificity of Heavy Soil Cultivation

When cultivating heavy soils, adherence to several important rules is necessary. Following the harvest of the forecrop, particularly after drought periods, it is recommended to immediately "break off" the top layer of soil, for example, using a disc harrow. This practice aims to reduce seepage and water loss from deeper soil layers while covering or mixing crop residues with the soil.

For spring plants, it is advisable to sow cover crops, preferably a mixture of seeds from different groups. Cover crops effectively fertilize the soil and significantly improve its structure. Regular sowing of ccover crops results in progressively better soil quality.

Disturbing the soil with a harrow or cultivator should be done in late autumn, maintaining the appropriate depth to ensure optimal conditions for future crops. In early spring, after deeper cultivation, it is necessary to level, loosen, and warm the top layer of soil to prevent water loss from deeper layers. Seeds should be sown after appropriate soil preparation.

Enhancing the quality of heavy soils

Enhancing the quality of heavy soils is crucial for their agricultural utility. Increasing humus content in heavy soils can be attained through natural fertilizers and suitable crop rotation. Comprehensive treatments and proper management are essential to positively impact humus content and improve cultivation value.

The fertility of heavy soils can be enhanced through appropriate agrotechnical methods and the combined use of treatments that improve soil structure and chemical composition. Proper management of heavy soils enables increased fertility and more efficient plant production.

Agrotechnical Treatments for Heavy Soils and Agricultural Machinery for Their Implementation

Improving the structure and properties of the soil enhances the efficiency of plant cultivation by providing optimal conditions for plant growth and development. Below are some essential agrotechnical procedures and machinery suitable for heavy soils:
Cultivation:
- Deep Plowing: Effective for heavy soils as it loosens the condensed earth structure and improves permeability. Heavy multi-furrow plows or chisel plows are often used for this purpose
- Loosening: Conducted using heavy disc harrows or cultivating units, this process breaks up clods of earth and improves soil structure, facilitating easier root development for sown plants.

Obtaining a Seedbed:
- To obtain a suitable seedbed on heavy soils, heavy tillage units, such as cultivators or disc harrows, can be used. These machines help in evenly distributing crop residues and preparing the ground for sowing. In the case of heavy, clay soils, they effectively break up lumps
- Weeding, mulching, and sowing cover crops
- Regular subsoiling at great depth to loosen the plow sole. Subsoiling should be carried out every few years.

In summary, heavy soils necessitate a specialized approach and appropriate agrotechnical measures to enhance their structure and properties. The use of suitable agricultural machinery, such as plows, harrows, and cultivators, is crucial for effective plant cultivation and achieving high yields on this type of land. Proper fertilization, plant protection, and regular agrotechnical practices help maintain the soil in good condition and ensure effective production.
