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 ...
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series.
Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this is calculated for a county , city , country , another territory or the entire world .
During the sugar beet harvest in late autumn in very moist soil condition, the lanes of agricultural equipment causes soil compaction of the clay soil. Soil compaction , also known as soil structure degradation , is the increase of bulk density or decrease in porosity of soil due to externally or internally applied loads. [ 1 ]
A high bulk density is indicative of either soil compaction or a mixture of soil textural classes in which small particles fill the voids among coarser particles. [52] Hence the positive correlation between the fractal dimension of soil, considered as a porous medium , and its bulk density, [ 53 ] that explains the poor hydraulic conductivity ...
For example, deforestation (the systematic and permanent conversion of previously forested land for other uses) has historically been a primary facilitator of land use and land cover change. [10] [11] The study of land change relies on the synthesis of a wide range of data and a diverse range of data collection methods. [12]
Several companies worldwide use leftover agricultural waste to make new products. [29] Reusing agricultural waste is in line with the desired circular economy. In today's economy, primary raw materials are mostly used. [30] Agricultural waste, on the other hand, is a secondary raw material.
Alternatively, for the purposes of agricultural statistics, [2] the term often has a more precise definition: Arable land is the land under temporary agricultural crops (multiple-cropped areas are counted only once), temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow (less
