Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...

A 2020 U.S. survey found that typical indoor agriculture crops, per pound of crop yield, consumed between US$0.47 (for leafy greens) and US$1.38 (for microgreens) in inputs (especially seed, growing media, and nutrients) -- though tomatoes were reported at US$0.06 inputs per pound. Labor costs for container farms were reported at US$2.35 per pound.
[1] As of 2015, the total arable land is 10.7% of the land surface, with 1.3% being permanent cropland. [13] [14] For example, the US Department of Agriculture has identified six major types of land use in the United States.
An area with a population density of up to 400 per square kilometer, Villages with clear surveyed boundaries but no municipal board, A minimum of 75% of male working population involved in agriculture and allied activities. [11] RBI defines rural areas as those areas with a population of less than 49,000 (tier -3 to tier-6 cities). [11]
Developments in shipping networks and technology have made long-distance distribution of agricultural produce feasible. Agricultural production across the world doubled four times between 1820 and 1975 (1820 to 1920; 1920 to 1950; 1950 to 1965; and 1965 to 1975) to feed a global population of one billion human beings in 1800 and 6.5 billion in ...
The soil bulk density of cultivated loam is about 1.1 to 1.4 g/cm 3 (for comparison water is 1.0 g/cm 3). [48] Contrary to particle density, soil bulk density is highly variable for a given soil, with a strong causal relationship with soil biological activity and management strategies. [49]
Many of the processes related to plant density can well be studied in monocultures of even-aged individuals that are sown or planted at the same time. These can be referred to as 'monostands' and are often studied in the context of agricultural, horticultural or silvicultural questions. However, they are also highly relevant in ecology. [4]
