These were large stone buildings with roofs thatched with "ichu" grass, or what is known as Peruvian feathergrass (''
Jarava ichu''). To a "prodigious
xtentunprecedented in the annals of world prehistory" the Incas stored food and other commodities which could be distributed to their armies, officials, conscripted laborers, and, in times of need, to the populace. The uncertainty of agriculture at the high altitudes which comprised most of the Inca Empire was among the factors which probably stimulated the construction of large numbers of qullqas.

s were capable of moving large amounts of bulky commodities. Nor did the Incas have a well-developed monetary, financial, or trading system to facilitate commerce. Thus, food and other items were stored near where they were produced and distributed by the State when necessary.
The response of the Incas to the challenges of their environment and technology was a huge and well-organized system of qullqas to collect and store food and other items during good harvest years for distribution when needed. Large numbers of qullqas were constructed near every major governmental center, state-owned farm, temple, and royal estate. Qullqas were built at every
"tambo", which were inns located a day's march, about , from each other along many of the of royal highways.
The qullqas were primarily used to supply Inca officials and armies on the move as they relied on the qullqas for food rather than foraging—to the deprivation of the agricultural population—which was the common means by which armies around the world supplied their needs until the modern era. Another use for the stored items, especially food, was for the ceremonial feasts that were an important part of the relationship between the rulers and their subjects. Food was also distributed to the general populace in cases of crop failures or shortages of food.
Products stored
The products stored in qullqas varied from region to region in the Inca Empire depending upon production in the local area. At

, a major Inca administrative and storage area, 50 to 80 percent of the qullqas were used to store dried potatoes and other root crops. Only 5 to 7 percent of qullqas were devoted to the storage of maize, probably because the high altitudes and cool climate limited the local production of maize. Root crops were layered with straw and baled for storage. Maize was shelled and stored in large jars.
Additional agriculture products stored in qullqas consisted of quinoa,

There are shields, beams for supporting house roofs, knives, and other tools; sandals and armor for the people of war in such quantity that it is not possible to comprehend.»
The economy of the Inca Empire was to a large extent redistributive. "The Inca state seems to have financed itself primarily through direct managerial command of land, labor, and storage systems, rather than through a market exchange system." Under the
mit'a system, citizens were required to contribute labor to the Empire and the resultant production of food, textiles, and other goods were stored by the State to be distributed as needed.
Agricultural products such as maize and quinoa might have had a storage life of one or two years and treated products such as freeze-dried potatoes and dried meat might have had a storage life of 2–4 years. However, early Spanish chroniclers said that some products were stored for up to 10 years.
Size, numbers and location

Qullqa's were generally built of masonry in connected groups on dry hillsides to take advantage of drainage and winds. Their size and design varied from region to region, but round qullqas were typically used to store maize and rectangular qullqas were used to store freeze-dried
potatoes

chuño") and other root crops. Qullqas had a ventilation system consisting of a channel beneath the floor to permit air to enter and an opening under the roof to allow air to escape.
The interior diameter of an average small qullqa was ; larger qullqas have a diameter of around . These smaller qullqa could have held of maize, and larger qullqa could have held about of maize.
Most of the remains of qullqas near Cuzco have disappeared due to urban expansion and development over the centuries. The largest remaining number of qullqas is in the
Mantaro River valley between the present days cities of
Huancayo and
Jauja, Peru. This broad valley, some long contains about of cultivatable lands ranging in elevation from to , the highest elevation at which cultivation was possible in this area.
The Mantaro Valley was one of the largest and most fertile high-altitude areas of the Inca Empire. 2,573 qullqas have been found in the valley by archaeologists. Half of them were placed in the center of this grain-producing area, another half scattered among 48 compounds along the course of the river. In total, the qullqas of the Mantaro Valley had a storage area of 170,000 square meters, possibly the largest storage facilities in the Inca Empire and in pre-Columbian America. Illustrating the quantity of stored items, these qullqas supplied and equipped an army of 35,000 soldiers during the Spanish conquest of the 1530s.
