Cottow-growing farm

Turkmenia has little water. Its few rivers ran dry at the height of the watering season.The 900-km Kara-Kum Canal, built in the fifties-sixties, brought water to the fields. The age-old dream of water came true. The canal now irrigates many thousands of hectares of virgin land. More than half of Turkmenian cotton grows there. There are numerous state farms on the banks of the canal, all of them big producers of the "white gold", fruit, grapes, meat, milk and fodder.

One of these cotton farms, the Tedzhen, is in an hour's drive south from the Tedzhen railway station. Its fields occupy over ten thousand hectares of the former desert. It is one of the Republic's most profitable farms.

The Tedzhen has become a school of efficient work for the other farms in the oasis. It uses the most advanced methods and equipment. Herbicides are used to kill off weeds, and organic, mineral and micro fertilizers are scientifically used in accordance with the soil maps. The organic-mineral mix for feeding the crops is prepared at special mechanized stations and sent directly to the fields.

The Tedzhen was the first farm in the area to introduce the advanced wide-row cotton-sowing method. The area around each plant has increased and they get more light and air – important for good yields. Tractor productivity in inter-row work has increased, and watering takes less time. This method gave a three-to-four-centner increase of cotton per hectare.

The farm's modern irrigation network eliminates water and soil losses. Mineralized subsoil water is piped away by an underground drainage system.

A machine testing station has been set up at the farm where the latest soil-cultivating, cotton-harvesting and irrigation equipment is tested. The machines that pass the test are recommended for wide use in cotton farming.

All the field work – from ploughing to cotton planting and harvesting – is mechanized.

New look at hydroponic culture

Thirty years ago, few dictionaries had the word "hydroponic". But today soilless growth has become a part of crop production. A recent world review on hydroponic development showed that there are over two million big soilless installations operating in many areas of the globe.

One of the main reasons why hydroponics is spreading so quickly is that new and simplified systems of soilless culture have been created. A set of rules has been worked out which makes hydroponics reliable for growers to use. Having one acre under hydroponics only takes up a man's time for a maximum of 40 working hours a month, or 10 hours if the unit is mechanized, while the gains may be very high. The larger the installation the lower are the unit costs, so that one fulltime individual can control 100 acres as easily as he could five acres, with mechanised aids.

Hydroponic machinery and equipment have the following categories:

1) machinery and equipment for supplying nutrients;

2) apparatus for irrigation;

3) prefabricated troughs1 and units.

Future developments may require computer control of hydroponic units, and we shall see vast complexes of food plants doing without direct human help.

Pumps, time-clocks, irrigation systems, piping, sprayers, tools of many kinds, heating apparatus for cold climates, and other machinery as well as various apparatus are required for hydroponic growth. Lighting and other electrical equipment are used in large units to increase production. Engines are needed to provide motive power, and there is a place for very low-geared tractors2 which can move at speeds of as little as one m.p.h., for nutrient application.

Irrigation machinery is important in hydroponics. So also are prefabricated troughs. Suitable materials for troughs include metal, wood, plastics, and any similar materials which do not give toxicity. Then there are many things such as polythene sheeting3, containers with automatic watering or feeding devices, tanks, tools, testing apparatus, photothermostats and humidity indicators, ventilation systems, etc. and, no doubt, computers.

Notes and Commentary

1 prefabricated troughs – лотки заводського виготовлення

2 low-geared tractors – низькошвидкісні трактори

3 sheeting – обшивка
