2.1 ការពណ៌នាដោយសង្ខេបពីបច្ចេកទេស

និយមន័យបច្ចេកទេស:

Mulch-till is a method of farming that does not utilise a plough, and thus the soil is not turned over. Furthermore, at least 30% of the cultivated area remains covered with organic residues left over from the previous crop. There are multiple benefits to the soil and carbon dioxide emissions are reduced.

2.2 ការពណ៌នាលម្អិតពីបច្ចេកទេស

ការពណ៌នា:

Mulch-till (also called “conservation agriculture” or “minimum tillage”) is a method of land management with modified, less intensive tillage, where land is covered with plant residues year-round (at least 30% cover) or grass, energy consumption is reduced, and there is less trampling/ compaction of the soil because of fewer machine passes and the protected surface. Under mulch-till, special agricultural machinery and attachments are required. Disc harrows and chisel ploughs are used to loosen the soil, and direct drills are employed for seeding. Ploughs are not used and the soil is not inverted. This method of tillage is intended to maintain soil structure, build up humus, improve nutrient supply and soil moisture, increase soil microbiological activity and also to prevent soil erosion. Mulch-till reduces the number of work operations on the cultivated area. Because the soil is disturbed less, this minimises the exposure of soil organic matter to the air, and therefore decreases the formation and release of CO2 to the atmosphere.
The debate over whether ploughing is still necessary has been going on for quite some time. Both mulch-till and ploughing have their advantages as well as disadvantages. Research shows that mulch-till reduces soil erosion and compaction, and this has a significant impact on soil fertility. On the other hand, ploughing better inhibits the spread of weeds and certain types of diseases and pests.
Mulch-till requires complete replacement of machines/tools, and this is a considerable initial investment. Regular annual maintenance of the equipment is needed also. Mulch-till provides full benefits after a number of years, through making sure that minimal soil inversion and organic soil coverage is guaranteed. It also requires good planning of crop rotation, the use of a special seed drill and employment of herbicides after emergence (or surface hoeing). Users mention one advantage being the low costs for tillage, which is less expensive than ploughing, and the reduction of soil erosion on sloping terrain. However, they do not like the high investment for equipment, possible lost of yields and increase in weeds: all tend to arise at the beginning of implementation. Knowledge and experience are required, as the technology is quite demanding, so there are chances of failure.

A few years ago, the farmer transitioned from traditional plowing to a mulch-tillage technique and has been using this method since 2020. In 2021, the farmer sought assistance from a consulting service to connect with the Biotechnical faculty in Ljubljana. Tests were conducted to assess the impact of conservation tillage. Following the positive results, the farmer has continued collaborating with the Biotechnical faculty and the public advisory service, further experimenting with the technology and maintaining the new cultivation approach. Today, he is one of the prominent advocates of conservation tillage.

មតិយោបល់:

The estimated lifespan of the equipment represents only an illustrative measure in terms of total hours, hectares, or machine work until its obsolescence. This data is not considered in the cost calculation. It is generally not economically viable to use a machine until its complete obsolescence, as it may become technologically outdated or require excessive investment for restoration compared to its economic usage. It is more sensible to use the machine's depreciation period. The average depreciation value is determined based on the average annual usage of the machine. The depreciation period for attachments is 12 years.

មតិយោបល់:

The initial establishment and investment costs for implementing the technology are high, and in the short term, the benefits may not be very noticeable or even negative compared to conservative technology. However, the long-term benefits are more significant and positive. While there are recurring costs involved, such as maintenance expenses, they are considerably lower compared to the initial investment costs. The technology requires substantial upfront investment in equipment, which can initially outweigh the immediate returns. It takes time for the technology to mature and for the full benefits to be realized. As the system becomes established and optimized, the positive outcomes become more apparent over the long run. Additionally, the lower costs mentioned refer to the ongoing maintenance and operational expenses required to sustain the technology (machines), which are generally lower than the initial investment costs. These costs are often outweighed by the benefits gained from improved efficiency, reduced resource consumption, and other long-term advantages. Therefore, while the short-term returns may not be overwhelmingly positive, the investment in the technology pays off over time, with greater benefits and lower operational costs.

In the long term it enables the achievement of better soil conditions, in terms of appropriate ratios of water, air, nutrients, organic matter, microbial activity, pH, microbial activity, pH and other factors of soil fertility.
Compaction and drying of the top layer of the soil is significantly less frequent and as a result losses of young plants are therefore smaller.
It reduces the potential for soil erosion. A major threat to soil fertility is erosion processes (wind, water and other erosion), where the most fertile surface layers of the soil are carried away to other parts of the ecosystem that are not intended for food production.
It brings advantages in terms of energy consumption and the possibility of carrying out production tasks in a shorter time and in difficult weather conditions. Conservation tillage tools typically operate in a shallower soil layer and mix less soil mass, it enables the use of tools with larger working widths and thus less unproductive driving in the field.
Benefits in terms of reduced transfer of phytopharmaceuticals and nutrients excess from the cultivation area to water and other ecosystems.
Reduced tillage improves soil quality, reduces nutrient leaching and lowers greenhouse gas emissions.
Benefits in terms of bioavailability and nutrient uptake efficiency.
Benefits in terms of greater adaptability of crops to extreme weather events.
Benefits in terms of maintaining the overall biological diversity of the agricultural landscape and soil.

An increase in the occurrence of certain types of weeds and a high dependence on certain types of herbicides. Some studies show that the introduction of conservation tillage slightly increases losses from certain diseases and pests.	For successful weed control, it is important to have a varied crop rotation, frequent sowing of cover crops and intercrops, and that the weeds never leave uncontrolled development on the stubble. The variegated crop rotation is meant as an obstacle that interrupts the development cycle of diseases and pests. How we handle harvest residues is also important. The more finely they are chopped by combines, mulchers or tools for vertical tillage before sowing, the faster they decompose and the worse the chances of harmful organisms developing on them. An evenly distributed mulch of harvest residues should remain, which prevents the emergence of new waves of weeds. These additional measures, together with mechanical weed control with new types of tools, allow limiting the weed population to a level that can be controlled with a limited range of herbicides.
Investment costs in machines designed for the method of soil cultivation can be very high. An important obstacle in the introduction of conservation tillage is the large investments in new machinery... The value of purchasing these tools can well exceed the amount of 100,000 euros for an individual farm, which is a practically unfeasible investment for small farms.	Small farms can take the transition to conservation farming only with the help of hired machinery services from neighbouring large farms that have been able to invest in new equipment. The subsidization of the purchase of machinery and also the economic legal status of the farm in terms of VAT calculation play an important role.
It is necessary to replace all the tools used by farmers according to the old methods of tillage. It is necessary to purchase adapted cultivators, harrows, looseners and especially seeder drills.	Increase in the supply of relatively inexpensive machines from manufacturers from Eastern Europe and Turkey, which can increase the availability of this equipment to smaller farms.
In the first years of the transition period, there may be a significant reduction in yields and poor financial results. There is a yield reduction and financial stress during the transition period to the new system. The transition from conventional cultivation to conservation tillage is usually difficult and risky.	Growers must be financially strong in order to make the transition, and the areas under alternative cultivation systems must increase gradually when they really master the new cultivation technique. Good financial support during the transition period is very important for small farms with weak investment assets. Targeted education and training is necessary, as technological errors due to lack of knowledge regarding the implementation of conservation cultivation in different soil types can be economically very fatal.
A small increase in the seeding rate (10 to 15 %) is often recommended to compensate for losses caused by diseases and pests at the time of plant emergence.	A necessary cost that must be accepted (higher sowing rate for the main crops and additional crops – cover crops) for the successful implementation of the measure.
