Financing

The beginning of scientific research experimental designing work until 2007, the development was carried out at the expense of personal financing.

Short description

Main features of drip and subsoil irrigation, conditions, and prospective of its usage are analyzed. Technique and technology of subsoil irrigation are examined in detail, parameters for systems of subsoil irrigation are substantiated, and methods to calculate irrigating rates under drip irrigation are designed.

The results of long term experimental work relating to cultivation of different commercial crop under drip and subsoil irrigation are summarized by authors of the research. Consideration of irrigating regimes, evapotranspiration, specific water consumption to obtain a unit of production, bioclimatic ratios, root system formation, development of photosynthetic activity in relation to water, nutrient regimes of soil change and levels of planned harvests is presented.

Evaluation of general and individual cultivated crop productivity, quality indicators of harvest, and also agroenergetic productivity of used methods and technology are given.

Implementation of recommended technology of subsoil and drip irrigation of apple orchard, oriented to obtain 17 to 20 ton apples per hectare is economically profitable. Economic effect of subsoil irrigation, providing hold up of soil humidity at 70 % of lowest water holding capacity, is 68 000 rubles with income index of 2.10. The term to pay off the invested funds, taking in consideration building spending, amounts to 2.4–4.1 of a year.

Main competitive advantages

Marketing research is carried out since 1993 till now.

Advantages of subsoil and drip irrigation:

• relatively simple emitting of water and nutrients directly into the root system of the crop;
• preserving the soil structure;
• increasing the ration of land usage;
• lowing water evaporation;
• possibility to use both pure natural water and sewage;
• saving the irrigating water comparing to surface irrigation and sprinkling;
• increasing harvests of commercial crop;
• elimination of soil erosion.

Scientific significance

On the given subject two candidates’ and one doctors’ theses were defended, two monographs were written, more than 200 works in scientific journals, conference materials were published. The Gold Medal was obtained in 2008 for the monograph “technique and technology of cultivation of commercial crop under drip and subsoil irrigation” at 10th anniversary Agricultural exhibition “Golden Autumn — 2008” in the nomination “For innovative working outs in the field of agricultural science”.

Practical application examples

Practical importance consists of scientific substantiation and experimental confirmation of economic expediency and ecological safety of development water saving irrigating methods under specific natural conditions.

Obtained data can be used by scientific-research and project organizations when develop projects of systems for drip and subsoil irrigation, specialists of firms and companies when exploit such systems, and also by teachers, students and post graduate students of agricultural institutes and universities in the process of education.

Markets geography

Both on the territory of Russia and contiguous states. Time of market entry is about a year.
