2.1 Courte description de la Technologie

Définition de la Technologie:

No tillage is based on direct seeding with the innovative/ modern direct seeder Condor and works without any kind of soil disturbance.

2.2 Description détaillée de la Technologie

Description:

"No-Till" is a key element of the ‘modern cropping system/ Canadian System’ in the Kulunda steppe. In contrast to minimum tillage an innovative modern direct seeding machine is used. The successful implementation of “No-Till” requires an adaptation of the whole cropping system including crop rotation. Rotation includes a succession of cereal crops (e.g. spring wheat), legumes (peas), and oil seed crops. In the study area predominantly spring cereals are grown. The direct seeder ‘Condor tine seeder’ (Amazone) was used for direct seeding. In contrast to the SZS 2.1 seeder used for minimum tillage it has flexible, individually depth-guided tine coulters, which ensure a high precision of seed placement. When opening the seed furrow, the narrow coulter moves little soil, so that the valuable soil moisture remains in the soil, and there is sufficient fine soil to ensure the optimum seed/ soil contact. Straw is safely cleared from the seed furrow, preventing the "hairpinning-effect" which is the pressing of straw by the coulter into the sowing slit. During the sowing period fertilizers are applied and broad spectrum herbicide in autumn and selective pesticides in the growing season are sprayed which help to increase yield.

No-till works without intensive primary tillage and stubble cultivation that saves time, fuel and reduces soil water evaporation. No-till increases soil aggregate stability, helps to reduce the risk of soil erosion, leads to a higher soil fertility and reduces soil water losses. Weed control through crop rotation and herbicide application allows to omit mechanical weeding and thus to protect the soil against fertility decline and soil water loss. Fertilization becomes more important, because of the decreased mineralization rate under no soil tillage, especially at the beginning of the conversion of the cropping system and until soil organic matter could build up in the soil.

The Technology including crop rotation was tested in the field in 4 test plots with 4 repetitions at the test site in Poluyamki. Results showed that the intensity of soil tillage and seeding methods used had a great influence on crop establishment and expected yields. It was demonstrated that no tillage leads to higher water use efficiency and highest yields. Positive effects were also observed regarding soil structure and soil fertility already after 3 years. Positive effects were also observed regarding soil structure and soil fertility already after 3 years. Minimized soil disturbance led to higher aggregate stability, which leads to a lower risk of wind erosion, increased soil organic carbon storage and soil fertility as well as available soil water content. The Modern Canadian system caused fixed production costs in form of annual depreciation and also additional costs due to the application of fertilizers and pesticides, the prices of which increased in the last four years. Due to not finalised land rights reforms, uncertain credits and harvest insurance farmers are reluctant to invest in new machines.

The test site in Poluyamki is located in the dry steppe of the border region next to Kazakhstan, where, due to the climatic conditions, no natural afforestation occurs, and the planted windbreaks don’t grow vigorously due to the prevailing aridity. The annual precipitation is under 300 mm a year. Probably the greatest climatic influence factor is the precipitation - in terms of quantity and space/ time distribution and, due to high summer temperatures, the high rates of evapotranspiration. The total yearly precipitation rate is the primary yield-limiting factor in all steppe regions. The ratio between precipitation and evaporation is negative. In the late weeks of spring, prolonged droughts must be expected in 5-year cycles, limiting germination and crop establishment. The soils are classed among those of cool-tempered grasslands. Due to their physical and chemical characteristics, these soils (Chernozems and Kastanozems) have high agronomic potential.

Commentaires (type de projet, etc.) :

Since the collapse of the Soviet Union increasingly innovative conservation technologies that are being developed in research experiments are implemented in practice. But the no technology of "No-till" as the most extreme form of conservation tillage is rarely applied in the study area. Thus the tested no-system is highly innovative for the Kulunda steppe.

3.1 Principal(aux) objectif(s) de la Technologie

• améliorer la production
• réduire, prévenir, restaurer les terres dégradées

3.2 Type(s) actuel(s) d'utilisation des terres, là où la Technologie est appliquée

Commentaires:

Major land use problems (compiler’s opinion): It's the decrease of soil organic carbon content in the soils, topsoil thickness through deflation and soil compaction, which lead to a decrease of soil fertility. Additionally, the negative soil water balance due to the high summer temperatures and evaporation and in addition the high spatial and temporal variability of precipitation as a serious problem relating to the lack of soil water.
Major land use problems (land users’ perception): The land user that we work with and that implement the our new farming practices have a similar opinion relating the land use problems like the research staff of the project. But there are still a lot of farmer, that underestimate the ecological risks of soil degradation resulting from traditional soil management.

6.5 Adoption de la Technologie

Commentaires:

100% of land user families have adopted the Technology without any external material support
The 3 farms where we have tested the technology of minimum tillage will partly apply this technology on their farming land. But it must be considered that the test farms of the KULUNDA project were interested in conservation technologies already at the beginning at the project and they are able to invest in new machinery to implement the tested SLM technology, that is not representative for the whole Kulunda-region.
There is a little trend towards spontaneous adoption of the Technology
There is a trend towards spontaneous adoption of the Technology, but this trend depends on different natural and socioeconomic factors like the precipitation or conditions an economic situation of the financial power of the farms. For example the drier the conditions, the more sense is to minimize the tillage. But there is a need to invest in new machinery. In contrast to the Adapted cropping system (with minimum tillage) the modern Canadian system require new seeding machinery that that means high establishment cost. Therefore the implementation growth is not so significant compared to the adapted system that use already existing Soviet seeding machinery.
