Liebig's law has been extended to biological populations (and is commonly used in ecosystem modelling).For example, the growth of an organism such as a plant may be dependent on a number of different factors, such as sunlight or mineral nutrients (e.g., nitrate or phosphate).
A container garden in large plastic planters. Container or bucket gardening involves growing plants in some type of container, whether it be commercially produced or an everyday object such as 5-gallon bucket, wooden crate, plastic storage container, kiddie pool, etc. Container gardening is convenient for those with limited spaces because the containers can be placed anywhere and as single ...
An agroecosystem can be seen as not restricted to the immediate site of agricultural activity (e.g. the farm). That is, it includes the region that is impacted by this activity, usually by changes to the complexity of species assemblages and energy flows , as well as to the net nutrient balance .
Agroecology is a holistic approach that seeks to reconcile agriculture and local communities with natural processes for the common benefit of nature and livelihoods. [ 5 ] Agroecology is inherently multidisciplinary, including sciences such as agronomy , ecology , environmental science , sociology , economics , history and others. [ 3 ]
If excessive use was made of common land, for example in overgrazing, a common would be "stinted", that is, a limit would be put on the number of animals each commoner was allowed to graze. These regulations were responsive to demographic and economic pressure; thus rather than let a common become degraded, access was restricted even further.
Animal genetic resources for food and agriculture (AnGR), also known as farm animal genetic resources or livestock biodiversity, are genetic resources (i.e., genetic material of actual or potential value) of avian and mammalian species, which are used for food and agriculture purposes. AnGR is a subset of and a specific element of agricultural ...
Companion planting of carrots and onions. The onion smell puts off carrot root fly, while the smell of carrots puts off onion fly. [1]Companion planting in gardening and agriculture is the planting of different crops in proximity for any of a number of different reasons, including weed suppression, pest control, pollination, providing habitat for beneficial insects, maximizing use of space ...
Agricultural soil science is the application of soil chemistry, physics, and biology dealing with the production of crops. In terms of soil chemistry , it places particular emphasis on plant nutrients of importance to farming and horticulture , especially with regard to soil fertility and fertilizer components.
