2.1 技术简介

技术定义:

Crop rotation is good practice in agricultural production. It comprises alternating different types of crops, usually in a specific order. Crop rotation maintains soil fertility, reduces the risk of diseases and pests, and optimizes nutrient utilization. In Slovenia, a 5-year rotation is proving especially effective.

2.2 技术的详细说明

说明:

Crop rotation is a system of alternating arable crops, forage plants, aromatic herbs, and vegetables, generally in a specific sequence. It can be applied in fields, gardens, or enclosed growing spaces. Crop rotation is adaptable and can be used under different farming systems, such as organic, integrated, and conventional farming. It maximises the efficiency of biological, organizational, and spatial influences on soil and plants. The fundamental element of crop rotation is the selection of plant species that are most effectively alternated on the same piece of land over different years. To ensure the best selection, it is essential to understand the farming technology, the type and structure of the soil, and its nutrient composition.
By implementing good crop rotation, nutrient utilization is optimized, and the risk of diseases and pests is reduced. Crop rotation also ensures the sustainable use of soil by improving its structure and fertility. The inclusion of cover crops in a rotation helps to maintain continuous soil cover. Crop rotation also facilitates better adaptation to climate change (drought, hail, floods etc), depending on the plants included in the rotation. The inclusion of green manure crops and the use of organic fertilizers can reinforce crop rotation and further support soil fertility enhancement and conservation.
To establish and maintain crop rotation, a detailed plan must be prepared, including the selection of crops based on soil characteristics, nutrient requirements, and crop sequencing needs. A fertilization plan should also be developed in parallel. It is crucial to ensure appropriate agricultural machinery, especially for specialty crops, and to have sufficient labour available, as more complex rotations may increase workload. Additionally, market research for new crops and demand assessment should be conducted.
In summary, crop rotation offers numerous benefits:
- Enhances soil fertility and improves soil structure.
- Reduces diseases, pests, and weeds.
- Minimises nutrient leaching and soil erosion.
- Increases organic matter content in the soil.
- Boosts biodiversity and strengthens soil resilience to weather changes.
- Enables efficient resource utilization and reduces production costs.
Thus, crop rotation offers numerous benefits that farmers appreciate – all of which help ensure higher and more sustainable yields. However, this technology requires specific knowledge, precise planning, and careful scheduling, which increases the complexity of production. It also demands more labour and sometimes additional machinery, leading to higher production costs. Furthermore, marketing various crops requires careful consideration, which can pose a challenge for farmers.
Crop rotation in Slovenia is supported by Agri-Environmental-Climate Payments (CAP), which enables farmers to receive funding for implementing a diverse and effective crop rotation system.

An effective 5-year rotation system in Slovenia typically follows the following sequence:
1st year – flowering grass mixture
2nd – winter barley
3rd – grain maize
4th – wheat
5th – oil pumpkins

This ensures that at least three different annual crops are grown within the five years, while integrating legumes like alfalfa or red clover every 3–4 years to enrich soil nitrogen levels. Cereals may appear up to three times in the rotation, but never in consecutive years. After cereal crops the farmer may alternatively sow non-winter-hardy honey-producing cover crops. Despite this structured guidance, many rotations in Slovenia remain too narrow. National laws and guidelines for agri-environmental measures support farmers in designing good crop sequences.

4.3 技术建立活动

	活动	时间（季度）
1.	Purchase of a roller	1st year

注释:

At the beginning, the farm is assumed to be equipped with standard agricultural machinery. However, to expand the crop rotation to a 5-year system, additional specialized equipment is usually required for cultivating new crops. Such machinery is later typically used for around 20 years or more, although the standard depreciation period for such equipment is approximately 12 years. This is only an estimated time frame, as actual usage may vary. Farmers generally continue using the roller as long as it remains functional and economically viable. Depreciation was not included in the cost calculation, as it is generally accounted for at the whole-farm level rather than per individual measure/crop production.

注释:

The farmer cultivates a total of 28.6 hectares of arable land, theoretically divided into five equal parts under the 5-year crop rotation system. For comparison purposes only, if a simpler system with just maize, wheat, and barley were used and the 28.6 ha were equally divided into three parts (9.53 ha per crop), the total variable costs would amount to 37,967.52 €. Such an even distribution is not practiced in reality—it is used here solely to illustrate the cost comparison.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

The total area is theoretically divided into five equal parts, following the 5-year crop rotation system. However, in practice, this division is not perfectly even. Other important cost factors include variations in input prices (such as seeds, fertilizers, and plant protection products), machinery costs, labor availability, and weather conditions that impact yields and operational efficiency.

6.4 成本效益分析

技术收益与技术建立成本相比如何（从土地使用者的角度看）？

技术收益与技术维护成本/经常性成本相比如何（从土地使用者的角度看）？

注释:

The establishment costs are relatively high due to investments in new machinery, which can be quite expensive. As a result, the short-term return is considered slightly negative. However, when comparing benefits with these costs, the long-term advantages—such as higher product quality, reduced yield losses, environmental protection, and increased diversification—have a neutral/ balanced impact, leading to more stable and resilient production. In the short term, the comparison of benefits with maintenance and recurrent costs is slightly negative, primarily due to increased labor requirements, the need for more knowledge, and a higher risk of errors. However, as these challenges are addressed and efficiency improves, the long-term outlook is slightly positive, especially due to the potential reduction in costs over time.

• 1-10%

在所有采用这项技术的人当中，有多少人是自发的，即未获得任何物质奖励/付款？:

• 0-10%

注释:

Most of the farmers decide for sustainable practices because of the subsidies, but there are three main reasons why many farmers don't adopt the subsidized form of 5 years crop rotation under the agri-environmental scheme (KOPOP), despite available support:
1. One of the specific conditions of the KOPOP measure is that farmers are not allowed to reduce their arable land area over the 5-year period. Due to uncertainty—especially regarding leased land—many farmers hesitate to commit.
2. Farmers prefer to maintain flexibility in their production choices so they can respond to market demand, grow more profitable crops, or focus on crops that are easier to cultivate.
3. Many farmers prioritize lower-cost production systems that offer higher profit margins, which discourages them from choosing more diverse and potentially riskier rotations.

6.6 适应

最近是否对该技术进行了修改以适应不断变化的条件？:

是

若是，说明它适应了哪些变化的条件:

• 不断变化的市场

具体说明技术的适应性（设计、材料/品种等）:

The specific changes in crop rotation often involve adjustments based on market conditions, input costs, or weather-related risks. For example, a farmer may decide to stop producing soy due to lower prices or higher production risks and instead increase the area under barley, which is less input-intensive and more market-stable. Such changes are made annually, allowing farmers to remain flexible within the broader rotation framework, even if they maintain a diverse system overall.
