Utilizing catch crops in ecoschemes to enhance soil quality
Eco-schemes provide support for farmers in ecological and chemical-free cultivation. Each farmer can voluntarily participate in their implementation. Pro-ecological policies encourage non-chemical soil fertilization methods through subsidies, aiming to replace spraying and artificial fertilizers. One fertilization method involves sowing catch crops, requiring the use of appropriate machinery like a seeder and considerable effort, which ultimately results in healthy, abundant, and environmentally friendly crops in the following agricultural year.
The importance of cover crops for soil health. What are catch crops and why are they sown?
What are catch crops? These are seed crops grown after the main harvest and play an important role in sustainable agriculture and agricultural ecosystems. The increased interest in them in the context of eco-schemes and subsidies is not surprising, especially as farmers try to maximize their income while taking care of the environment.

The "carbon farming" eco-scheme exemplifies the promotion of pro-ecological practices. By offering farmers financial incentives for cultivating winter cover crops, it encourages activities that benefit both the soil and the environment.

However, it is worth emphasizing that the benefits of cover crops extend beyond financial aspects. Cover crops play crucial roles in agricultural ecosystems, aiding in soil regeneration and protection. The long-term practice of monocultures can result in soil degradation and an increased risk of erosion. Cover crops, such as legumes and peas, enhance soil structure by providing organic material and supporting microorganism activity.

Cover Crop Cultivation Scheme
Upon the harvest of the main crop, cover crops are introduced to the fields, thereby accelerating ecological processes. These plants utilize crop residues and soil minerals to enhance the biological cycle. Rolmako's machinery plays a crucial role in optimizing land preparation and sowing for cover crops. Notably, cover crop management includes sowing, mulching post-November 15, and plowing post-February 15. It is imperative to abstain from chemical use throughout the eco-scheme participation period. Employing environmentally friendly machinery for ultra-shallow cultivation from Rolmako is essential for eco-scheme implementation. By selecting cover crops and avoiding chemicals, farmers support ecosystem balance and long-term soil fertility.

Which cover crops should be introduced into the field?
Cover crops emerge during the lower vegetation period, particularly in autumn, after the main crops have been harvested. Post-season field work, utilizing effective agricultural machinery, ensures high cultivation results in subsequent years. Modern agriculture presents numerous challenges, one of which is sustainable land management and maintaining soil fertility. In this context, the use of cover crops plays an essential role.

Types of cover crops
The selection of appropriate cover crops depends primarily on the soil type. Plants such as field beans, vetches, and narrow-leafed lupine work best in heavy soils. Soils of medium fertility respond well to lupine, field pea, and vetch. However, on soils of poorer quality, yellow lupine, serradella, trefoil, or phacelia will bring the best results. It is worth emphasizing that this is not only about improving soil structure or providing animal feed. Most plants included in cover crop mixtures have the ability to bind nitrogen in the soil, additionally enriching it with nutrients.

Features of cover crops
The most critical factor in selecting cover crops is their rapid growth and late flowering. Plants such as oats, rye, vetch, and lupine significantly enhance soil structure without competing with primary crops for nutrients. Additionally, the diversity of species in cover crops improves both the land's quality and structure, as well as benefiting the farmer. By integrating catch crops and utilizing agricultural machinery instead of chemicals, various subsidies and financial support may be available. In agricultural practice, for a catch crop to comply with the principles of the carbon farming ecoscheme, it must be sown as a mixture of at least two plant species from different groups.

Benefits of Introducing Catch Crops
The primary benefit is maintaining soil fertility and preventing nutrient losses. When fields are left unplanted, rapid mineralization and nitrogen loss occur. Catch crops such as red clover or yellow melilot accelerate mineralization processes while simultaneously accumulating nitrogen in their biomass. Upon decomposition, these nutrients are released into the soil, serving as a natural fertilizer for subsequent plants.

Another crucial aspect is enhancing soil structure. The diversity of cover crops, their root systems, and physiological properties impact the soil's physical and chemical attributes. For instance, deep-rooting plants like field beans or rapeseed can loosen heavy soils, thereby improving their permeability.

Protecting soil against erosion is critical. In agriculture, sowing catch crops can prevent water and wind erosion by mimicking natural processes. Additionally, catch crops can mitigate pest severity. Certain cover crops exhibit allelopathic effects that inhibit weed and pest growth and development.

We must also consider the economic aspects. Catch crops can provide additional feed for farm animals, which is crucial for organic farms with limited breeding. Green fodder from stubble catch crops is a valuable source of feed, particularly during drought periods.
The use of Rolmako machines in the cultivation of catch crops
Organic farming, aligned with eco-schemes to transition away from chemical fertilizers, herbicides, and pesticides, emphasizes the use of agricultural machinery. Mechanical agricultural cultivation adheres to longstanding traditions and is environmentally friendly. Knife rollers and their combinations with other tillage machines, such as ProCut and TurboCut from Rolmako or a combination of a disc harrow and a knife roller in one machine, are frequently used for cultivating catch crops. A viable solution to maximize results is to use a knife roller at the front of the tractor and a disc harrow traditionally aggregated at the rear three point linkage. It is also recommended to consider the tillage machines on which Rolmako builds cover crop seeders.

Selecting equipment from reputable manufacturers is crucial. Modern machinery enhances work quality, reduces time, and emits fewer exhaust gases. For catch crop cultivation and other agricultural tasks, opting for equipment from trusted manufacturers is advisable. High durability and advanced technology are key to success in any field, including agriculture.

Terminology
Monoculture – An agricultural system involving the cultivation of a single species or plants with similar soil requirements in the same area for many years, such as cotton, sugar cane, and spruce. This practice leads to rapid sterilization of even highly fertile lands and alters their structure.
Pests – Pathogens, pests, and weeds that reduce crop yields. Worldwide losses due to pests amount to approximately 35%, and approximately 15% in Poland.
Allelopathy – The harmful or beneficial effects of chemical substances secreted by plants or fungi of a given species, or originating from the decomposition of these plants or fungi.
