2. SLM技术的说明

2.1 技术简介

技术定义:

In the municipality of Dedoplistskaro, Georgia, 100 ha of land have been cultivated with peas on approx. 25 fields (each 1-10 ha in size). The introduction of peas as an alternative crop that is now used in rotation with wheat, helps to increase soil fertility sustainable and ecologically.

2.2 技术的详细说明

说明:

Dedoplistskaro is located in the Shiraki Plain, in eastern Georgia, and consists of steppes, where grain crops are cultivated and livestock is grazed in the winter. The steppic soils are dominated by Chernozems and Kastanozems, the climate is warm and temperate and the small-scale land (2-5 ha) is in individual ownership. The labour including plowing, seeding and harvesting is fully mechanised, the machines are mainly borrowed from agricultural machinery cooperatives and less often from private machinery suppliers. For the inhabitants of Dedoplistskaro municipality, agricultural production is an important source of income. 74% of the Georgian wheat production is located in the Kakheti region. Shiraki valley has a great share of this. The area of wheat production in Dedoplistskaro is 13,693 ha (Census 2014). Securing the productivity of arable land and stopping degradation due to the loss of soil fertility is of local and national importance. The introduction of pea as an alternative crop, which can be used in rotation with wheat or other crops, should help to increase soil fertility in a sustainable and ecologically viable way. Pea is a plant from the legume plant family. The root system of Pea can thus fix nitrogen from air by symbiotic bacteria. This helps to increase the C/N ratio in the soil leading to higher decay rates of organic carbon (e.g. from straw residuals) and higher fertility of soils. Most farmers sowed on 23 and 24 March 2018 - some until 29 March 2018. Later sowing led to lower yields.

The costs stated in the section "Labour" for plowing, harrowing, seeding and harvesting include costs for labour and for equipment. The work was done partly by the farmers themselves and partly by an agricultural contractor such as for driving the harvester.

注释/具体说明:

The average yield of peas 3 t/ha, 98 t pea yield was taken from the pilot plots. Some of the farmers will sow the peas in other plots to improve soil fertility on another land under their ownership. Buckwheat was sown only on 2 plots, 450 kg at all. The farmers who had opted for the concept of starting the crop rotation with buckwheat cultivated the green mass in the soil to improve their fertility. The harvest of peas/buckwheat was very variable between the different farmers depending on their timing of measures: 1. The farmers who could not use the possibility to seed the crops in March - 1 farmer, because of rainy weathers afterwards, seeded pea later , in the middle of April. This farmer could not get yield from the plot. The others (2-3 farmers) who could not harrow the soil after seeding (as we recommended to harrow), they got the small yield.

对现场影响的评估(测量)进行具体说明:

When peas are used as a intercrop between winter wheat cultivation, this would have a positive effect on wind erosion. Since the implementation of the crop rotation just started in 2018, evidence-based further impacts are only expected in the following years, e.g. impacts on soil quality.

6.7 该技术的优点/长处/机会

土地使用者眼中的长处/优势/机会
The project gave farmers the opportunity to try the new crops (peas and buckwheat) for the community of Dedoplistsakro, as they only sow wheat and barley over the years. They had the opportunity to get advice on how to sow peas and buckwheat and how to improve the soil fertility of their land. They invested through ploughing, harrowing and maintenance, as well as by taking over the yields. They were also interested in maintaining the yield from the proposed crops, using this seed for further plots next year and passing on the knowledge to other farmers. Some farmers sold harvested peas as forage, some gifted others for the same purposes to improve soil fertility.
The farmers, who sow the peas in time and cultivate them with appropriate agrotechnical measures, harvested 3.5-4t/ha. The profit was 12 250 - 14 000 GEL/ha. The yield rate was as follows: 3.5.5 t/ha yield - 4.8 yield rate; 4 t/ha --- 5.5 yield rate.
The expected yield of barley per hectare in the years following pea sowing will be 7-9 tonnes. Income ratios - 9.6 for 7 t/ha yield; 12.4 for 9 t/ha yield. The expert calculated the expected yield on the basis of yield data from the davit Nateladze area in Dedoplistskaro, where peas were sown in 2017 and then 5.5 t barley/ha instead of 1.5 t barley/ha (in previous years before peas were sown) was harvested.
As part of the pilot project, 23,750 kg of peas were sown on 92 ha in Dedoplistskaro in 2018. 98 t of peas were harvested in mid-July in the municipality of Dedoplistskaro.
编制者或其他关键资源人员认为的长处/优势/机会
The machinery for preparing the soil and seeding are available.
Especially pea has a very positive effect on soil fertility.
Most of the farmers used the technology for next year(2019). They seeded the harvested pea in spring 2019 at another plots in Dedoplistsakro municipality (about 100 ha). This confirms the positive impact of the approach on soil fertility and guarantees the sustainability of the project.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险 如何克服它们?
Some farmers (2-3) sow the pea later than others. They did not get a good yield because of the sowing in April. The reason for the delay was 1. rainy weather; 2. lack of machinery. Timely harvesting was also the problem because of the lack of machinery, since Dedoplistskaro is called the barn of wheat and there are not enough machines in the community. The problem of the realization of peas and buckwheat was also the problem because of the lack of companies for peas and buckwheat not only in the municipality but throughout the country. The farmers asked for a support for the municipality in the development of such enterprises to process the mentioned crops for realization.
Of the 3 schemes proposed, 19 farmers choose the first scheme to sow the peas in the first year. The second scheme was not chosen at all. The 3rd scheme to start crop rotation in the 1st year with buckwheat was chosen by 2 farmers. A farmer ploughs the yield of buckwheat as a green mass in the soil and improves the fertility of the soil. Another harvested and prepared 120 hay presses. The farmers improved the soil, but the expenses were at 1 ha / 2 645 GEL, 1 press / 7 GEL, the income ratio 0,31. The sowing of buckwheat to prepare the press is ineffective to benefit from the harvest. The farmers who opted for the third scheme (start of croprotation with buckwheat) were geared towards improving soil fertility, but most farmers prefer to do the rotation in order to benefit from the yield.
编制者或其他关键资源人员认为的弱点/缺点/风险 如何克服它们?
There is no local marked or seller for peas and it is difficult to sell the product for the local farmers. It needs national support to develop a pea-processing industry.
