1. What soils is furrow irrigation adaptable to?

2. What ways may water be released from field supply to furrows?

Furrow Irrigation

Furrow irrigation is one of the most common methods of surface water application in farming to day. Furrow irrigation is adaptable to all row crops all soils except very sandy types with high intake rates.

When using the furrow method, ideally just enough water should be released in each furrow to water its entire length any run-off.

Water may be released from the field supply to furrows through ditch openings, hydrants, siphon tubes or gated pipes. The latter two methods are most generally used and provide the best control for efficient irrigation.

Dry soil will absorb water faster than its basic intake rate, so a larger volume of water should be applied at the start of irrigation of each furrow so as to wet its entire length as possible.

V. Прочитайте текст "Aeration Irrigation", письменно ответьте на вопросы.

1. What does aeration irrigation mean?

2. What are the advantages of aeration irrigation?

Aeration Irrigation

The principle of aeration irrigation involves a combination of air and irrigation water.

Basically aeration irrigation means reducing the water application rate to approximately 50% of the soil intake rate and irrigating a set for a period twice as long as would normally be used. In theory, air is taken into the soil along with water when this lighter application rate is used.

The advantages of this method are the elimination of soil compaction, water runoff, and the overall improvement of the soil structure. Silt particles are never disturbed and a supply of air and oxygen is always present in the plant feeder root zone.

Maintaining this condition means increased activity of soil bacteria and microorganisms which leads to soil improvement through the movement of carbon dioxide, ammonia, nitrogen and minerals. Greater yields have been a characteristic result when crops were sprinkled at this light application rate.
