Capillary water is retained on the soil particles by surface forces. It is held so strongly that gravity can not remove it from the soil particles. The molecules of capillary water are free and mobile and are present in a liquid state. Plant roots are able to absorb it. Capillary water is, therefore, also known as available water.

Shifting cultivation is a form of agriculture in which the cultivated or cropped area is shifted regularly to allow soil properties to recover under conditions of natural successive stages of re-growth.

In a shifting cultivation system, at any particular point in time, a minority of ‘fields’ is in cultivation and a majority are in various stages of natural re-growth.

Over time, fields are cultivated for a relatively short time, and allowed to recover, or are fallowed, for a relatively long time. Eventually, a previously cultivated field will be cleared of the natural vegetation and planted in crops again. Fields in established and stable shifting cultivation systems are cultivated and fallowed cyclically. This type of farming is called jhumming in India.

It has been practised in the forested regions of the Central highlands of India which comprise three main plateaus — the Malwa Plateau in the west, the Deccan Plateau in the south (covering most of the Indian peninsula) and the Chhota Nagpur Plateau in the east.

Well distributed rainfall ranging from around 2000 mm to 5000 mm is considered suitable for a successful tea plantation.

The monthly average maximum temperature ranging between 28°C and 32°C during April to September, with occasional rise up to 36° - 37° C is good for the plantation.

Tea is planted in flat and slightly undulating land at an elevation ranging from 20 to 250 m above sea level in the major part of the plains of NE India.

On the hill slopes of Darjeeling and South India, it is planted up to a height of 2000 m above sea level. The state of Assam is the world’s largest tea-growing region.

It experiences high precipitation; during the monsoon period, as much as 10 to 12 inches (250–300 mm) of rain per day.
