Development of an agro-ameliorative passport - one of the ways to increase the knowledge of land users

Author: Knowledge Management in CACILM Phase II, ICARDA.

Definition of approach:

Agro-ameliorative passport of farmer's field, including full information on soil ameliorative and climatic conditions of the field, topography, nutrients, salinity, etc, is a demonstration tool for decision-making for efficient agricultural production.

Brief description of approach:

Agricultural reforms in Uzbekistan contributed to the formation of many small farm entities. Owners of the land were the representatives of different professions, often not associated with agricultural production. This largely explains failures and mistakes of the farmers, leading to a decrease of crop yields and decline of soil fertility.

One of the forms of increased knowledge of land users is the development of Agro-ameliorative passport (AMPP) of the field (farm). AMPP is a generalization of agronomic information and contains main agronomic documentation of the specific site, as well as some reference data, regulatory materials and recommendations that are needed in agriculture and crop production.

AMPP contains 18 pages and includes the following main important information:

- Areal assessment of the field (gross, net, unused land, areas under roads, collector-drainage networks, irrigation network);

- cropping pattern and levels of their productivity;

- main agronomic characteristics of soils;

- average annual climatic data;

- topography (planar and spatial representation of the field geometry);

- cartograms of availability of soil humus, nitrogen, phosphorus, potassium, salinity and texture of the 1-m soil layer by horizons  etc.

Most of the information is presented in a graphical form that clearly reflects field characteristics. Cartograms allow observing specific parts of the field that require leaching, leveling, differential fertilizer applications, etc. Annual inclusion of a new information extends AMPP service to 10 years. The passport allows farmers to choose the right decisions during implementation of the technological works, to carry out an objective analysis of the dynamics of agricultural production and improve farming.

Location: Syrdarya, Tashkent, Djizak provinces.

Area of application approach: 23000 ha.

Stage of intervention: alleviation / reduction of land degradation.

Main land use issues and the main causes of land degradation:

Insufficient level of consulting services, lack of knowledge in most of the land users, poor access to information about the current agricultural situation, modern technologies and methods of production in specific natural, soil-amelioration conditions contribute to loss of crop yields, reduction of soil fertility and development of degradation processes.

Purpose of approach:

Raising knowledge of land users, helping farmers to choose the right decisions when performing the technological works, carrying out an objective analysis of the dynamics of agricultural production and improve the culture of farming.


Impact of technology

Main advantages:

- provides main information about soil of the field and recommendations for actions to be followed by a farmer;

- spatial representation of the field characteristics allows differentiating system of recommendations, thus saving finantial resources, equipment and labor costs;

- increasing land productivity by application of scientific recommendations;

- provides land users with possibility to improve their potential and knowledge for agricultural practices.

Main disadvantages:

- additional financial costs for a more detailed field studies, in contrast with annually conducted salinity assessments and periodic refinement of soil bonitet.

Acceptance/adoption of technology: Certification was conducted in 23,000 ha of farmland in Tashkent, Jizzakh and Syrdarya provinces of Uzbekistan.
