2.1 وصف مختصر للتقنية

تعريف التقنية:

Minimum tillage is a one-pass operation combined with sowing, using a classic Russian seeder modified for seedbed preparation and soil mixing. It can include shallow stubble cultivation after harvesting.

2.2 وصف تفصيلي للتقنية

الوصف:

Minimum tillage is a key element of the "adapted Soviet cropping system", which aims at more sustainable land use but based on predominantly local technologies. For successful implementation of minimum tillage, adaption of the whole cropping system is required, including crop rotation. Rotation includes a succession of cereal crops (e.g. spring wheat), legumes (peas), and oil seed crops. Stubble cultivation in autumn is best performed with the "Catros" compact disc harrow for a quick, shallow operation. Seedbed preparation is carried out using a classic Russian seeder modified with wing shares for shallow seedbed preparation including soil mixing. In general, the performance of this drill is very close to that of a cultivator.

Minimizing tillage, saves time and fuel, and also helps to reduce evaporation, as well as protecting the soil against erosion. Shallow tillage with disc harrows after harvest ensures better stubble mixing and stimulates the germination of weed seeds. The adapted seeder, SZS 2.1, works with wing shares that open the soil and place the seed. Thus traditional deep tillage operations for the preparation of the seedbed can are omitted: that helps to reduce costs. With respect to crop protection, the first and most important element is to implement a full crop rotation. To control late germinating weeds and seeds of the previous crop, a disc harrow is used for shallow cultivation – this can be supplemented by the application of a non-selective herbicide if there is germination - to avoid the risk of flowering before the hard frost sets in. Fertilization becomes more important, because of the decreased mineralization rate under minimized soil tillage, especially at the beginning of the conversion of the cropping system.

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 minimizing 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. 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 adapted Soviet system is more profitable, due to higher gross margins.

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.

التعليقات (نوع المشروع، الخ):

Already during the Soviet land use periode temporal,especially after the Virgin land campagne (1954-'63)efforts were made to minimize soil tillage intensity to obtain from conventional ploughing system. An important scientific thinker for this innovative farming systems was T. C. Malcev. But at this time the new approaches for minimized tillage systems were not seriously implemented in Russia. Only in the last decade a significant trend towards minimum soil tillage can be recodnized in the Russian agriculture

3.1 الغرض الرئيسي ( الأغراض الرئيسية) للتقنية

• تحسين الإنتاج
• الحد من تدهور الأراضي ومنعه وعكسه

3.2 نوع (أنواع) استخدام الأراضي الحالية حيث يتم تطبيق التقنية

التعليقات:

Major land use problems (compiler’s opinion): The decrease of soil organic carbon content in the soils and loss of topsoil depth has led to a decrease in soil fertility. Additionally, the negative soil water balance due to the high summer temperatures and evaporation, and the high spatial and temporal variability of precipitation, is a serious problem relating to the lack of soil water.
Major land use problems (land users’ perception): The land users who were involved in the studies and implemented the new farming practices have a similar opinion. But there are still a lot of farmers that underestimate the ecological risks of soil degradation resulting from conventional/ traditional soil management.

التعليقات:

The increase of air temperature and wind lead to an increase of the evapotransporation rate and consequently, as well as rainfall decrease and droughts, to a decrease of soil water content that is one of the most important limiting factor in crop production. The minimization of soil tillage intensity helps to reduce the evapotranspiration rate and thus leads to a higher soil water content. The stubble slow down the wind, that protect the soil against erosion and reduce the evapotranspiration rate.

6.5 اعتماد التقنية

التعليقات:

100% of land user families have adopted the Technology without any external material support

The 3 farms/ sites where minimum tillage was tested were already interested in conservation technologies and were able to invest in new machinery, which is not representative of the whole Kulunda region. There is a moderate trend towards spontaneous adoption, but this trend depends on different natural and socioeconomic factors, like precipitation or the economic situation and financial power of the farmers.
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. An advantage of the tested Adapted Soviet System in contrast to the Modern Soviet System is the less need for new machinery through the use of old Soviet machinery.

6.7 نقاط القوة / المزايا / الفرص التي توفرها التقنية

نقاط القوة/ المزايا/ الفرص من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات
Increase of soil aggregate stability and improved soil structure thus better erosion control and protection of soil organic matter will improve soil fertility and water holding capacity
Minimization of evaporation losses through the mulch layer
Protection of soil organisms thus ensuring natural soil forming processes
Lower input costs (materials, fuel, labour, time) and quicker field operations.
A great advantage of the tested ‘minimum tillage’ in contrast to ‘no till‘ is that the former needs no new machinery because of the use and adaptation of old Soviet machinery.

6.8 نقاط ضعف / مساوىء / مخاطر التقنية وسبل التغلب عليها

نقاط الضعف/ المساوىء/ المخاطر من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات	كيف يمكن التغلب عليها؟
Need for comprehensive system knowledge and risk of significant crop losses in case of incorrect implementation	Knowledge transfer, Capacity building and extension services, State support (subsidies for new technologies)
Application of chemical herbicides leads to higher costs and possible ecological risks	Selective spraying using the “Amaspot” system that is based on infrared detection of weeds.
Higher requirements for fertilizers, especially at the beginning, due to lower mineralization rates and less nutrient availability compared to conventional cultivation	Higher fertilizer application in the first years after conversion.
Challenging straw management that leads to higher risk of fungal infestation and poorer field crop emergence	Good straw management: effective straw chopping and spreading as well as stubble cultivation for an optimal straw/ soil ratio.
