2.1 技术简介

技术定义:

Reduced (minimum) tillage is a tillage method that does not turn the soil over. Usually only the upper 10-18 cm of the soil surface is tilled.

2.2 技术的详细说明

说明:

The technology is applied in sub-humid climate with an average of 696 mm of precipitations per year, from which more comes from July to October and less in March and April. Average annual temperature is +4 C, length of the growing period is 180-195 days. The territory is mostly flat, the southern part is hilly with slopes of 6-10%. Average altitude from the sea level is 50 m. About half of the Estonian territory is above 50 m and half is below it. Soils are from very shallow (less than 0.1 m) in the north to very deep (> 120m ) in the south. Soil cover is very variable. In the agricultural area the soils are medium textured with low (< 1%) to high (>5%) organic matter in topsoil. Groundwater is near the surface in wet soils and deep in hilly areas. Biodiversity varies from high to low depending on soil and landscape. Market orientation of production system is mixed and off-farm income is less than 10%. Relative level of wealth is average from individual households to cooperatives. Soil management is mechanized. Land belongs to land users, but is leased also in case of bigger farms (over 100 ha).
Reduced tillage is the tillage method used in agriculture to prepare the seedbed. Usually only the upper 10-18 cm of the soil surface is tilled. There is no use of ploughing and thus it is the method that does not turn the soil over. This may involve the use of a chisel plough, field cultivators, or other implements. Depth of the soil preparation depends on the culture in the rotation - before cereals 10-12 cm, before oilseed rape 15-18 cm. The main equipments to prepare the seedbed are the disc cultivator and the tine cultivator or a combined cultivator. The work can be ordered from contractors as well. Usually farms own the equipment.
The main goal is to maintain soil structure, to improve water infiltration, to reduce compaction, and to reduce fuel and labour costs. As there will remain 30% more residues on the soil surface it will promote the activity of soil organisms. Less disturbance in deeper layers increases number of earthworms and increases species diversity. The greatest benefits for the land users are the reduced fuel and labour costs. The reduced tillage is more suitable for crop rotations without root crops. For example, rotation can be as follow: winter oilseed rape - winter wheat - pea (or bean) - winter wheat - spring barley undersown with red clover - red clover. However, the soil compaction and weediness can drastically increase during the first years of the implementation without using a proper crop rotation or management plan. The soil conditions (compaction and weediness) can get worser inside the first 4 years and start to improve after that. It is not suitable for fields which are heavily affected by perennial weeds, as noninversional tillage can spread the weed roots and higher doses of herbicides are needed.

注释:

The labour costs are included to the machinery work costs. An average the labour cost for a driver is 15-18 EUR/ha. The average machinery work costs to produce 4.5 t of winter wheat were 388 EUR/ha, 355 EUR/ha and 322 EUR/ha in conventional, minimum and no-tillage, respectively in 2016. Cost of production in this case was 159 EUR/t, 152 EUR/t and 147 EUR/t in conventional, minimum and no-tillage, respectively.
To produce the same amount of spring barley, the cost of machinery was 365 EUR/ha, 345 EUR/ha and 300 EUR/ha in conventional, minimum and no-tillage, respectively. Cost of production in this case was 142 EUR/t, 139 EUR/t and 129 EUR/t in conventional, minimum and no-tillage, respectively.
The machinery cost for minimum tillage is 33 EUR and 20 EUR less than for conventional plough based tillage for winter wheat and spring barley, respectively.
By minimum tillage the use of fuel is ca 38% less than by ploughing.
