The essence of agricultural science is biology and economics
The agricultural sciences group studies agriculture with the support of its supporting sciences. the core of agricultural science is biology and economics. Because agriculture is always bound by space and time, supporting sciences, such as soil science, meteorology, agricultural inauguration, biochemistry, and staticka, are also studied in farming farming (farming) is a core part of agriculture because it involves a set of activities carried out in aquaculture. farmer is a term for those who run a farming business, for example “vegetable farmers” or “fish farmers”.
livestock farmers are specifically referred to as breeders agricultural science began with the work of gregor mendel in the field of genetics, but modern agricultural science can be said to begin in the 18th century when chemical fertilizers affected plant physiology and developing countries, often referred to as green revolution, which is the progress made in selecting and improving plant quality and livestock for high productivity, also the use of additional inputs such as fertilizers and pesticides (Maisuma Literature Reviews).
Agriculture in a broad sense includes all activities that involve the use of living things (including plants, animals, and microbes) for the benefit of humans.
In the strict sense, agriculture is also defined as the cultivation of certain types of plants, especially those that are seasonal
Agricultural business is given a special name for a particular farming subject. Forestry is a farming business with a plant subject (usually a tree) and is cultivated on semi-wild or wild land (forest). Farming uses the subject of dry land animals (especially all vertebrates except fish and amphibians) or insects (e.g. bees)
Fisheries have the subject of aquatic animals (including amphibians and all non-vertebrate aquatic). An agricultural business can include these subjects together for reasons of efficiency and increased profits.
Consideration of environmental sustainability brings aspects of conservation of natural resources to become part of the business agriculture
All agricultural businesses are basically economic activities so that they need the same basic knowledge of managing business premises, seed selection, cultivation methods, yield collection, product distribution, product management and packaging and marketing. If a farmer views all of these aspects with consideration of efficiency in order to achieve maximum profits, it engages in intensive farming.
Agricultural business which is seen in this way is known as agribusiness. Programs and policies that direct agricultural businesses to such perspectives are known as intensification. Because agriculture always implements intensive agriculture, both often likened.
As a business, agriculture has two important characteristics: it always involves goods in large volumes and the production process has a relatively high risk. These two characteristics arise because agriculture involves living things in one or several stages and requires space for the activity and a certain period of time. in the process of production, some forms of modern agriculture (eg hydroponic algal cultivation) have been able to reduce these characteristics.
agricultural science includes research and development in the fields of:
1. Production method (eg management function, recommended nitrogen input)
2. increasing agricultural productivity in terms of quantity and quality (selection of drought-resistant plants and animals, development of new pesticides, yield sensing technology, plant growth simulations, cell culture in vitro)
3. conversion of primary products into consumption materials (ranging from production, preservation, and packaging)
4. prevention and repair of environmental damage (soil conservation, soil degradation, waste management, bioremediation)
5. Theoretical production ecology, related to plant production modeling
6. Improvement of subsistence agriculture which feeds most of the poor people in the world. This system attracts attention because maintaining integration with natural ecological systems is better than industrial agriculture, which may be more sustainable than modern agricultural systems.
7. Food production based on global demand
Understanding the land is very diverse and depends on the field of science that evaluates it. The definition of land based on legal experts will be different from the definition of land according to economists, financial / banking institutions, and housewives. Land according to legal experts is assessed based on the status of land or ownership rights to land, such as land with different ownership rights with land with rights to use rights (HGU) and use rights and very different from arable land.
Land according to economists and banking financial institutions is understood based on the proximity of the location of the land with access and smooth access and proximity to the development center. Land near the road or near the development center has a higher economic value than land that is located far from the access road or far from the development center. Different from the definition of land according to housewives who always remind their children not to play with the land and always remind their children not to forget to wash their hands and feet when they get hit by the ground.
Understanding of soil learned in the Basic Soil Science course is based on agricultural science. The definition of land according to agricultural science has also been developed over time.
Changes to the definition are presented as follows:
In 2005 a doctor of soil science from Indonesia named Hanafiah defined the soil more comprehensively that the soil is the surface layer of the earth that physically functions as a place to grow and develop the roots of plants to grow upright and supply water and air needs; chemically functions as a storehouse of nutrients and a source of supply of nutrients or nutrients (includes: simple organic and inorganic compounds and essential elements such as N, P, K, Ca, Mg, S, Cu, Zn, Fe, Mn, B, and Cl ); and biologically it functions as a habitat for biota (organisms) that actively participates in the supply of these nutrients and additives (growth promoters, protection) for plants, all of which are integrally able to support soil productivity to produce biomass and good production of food plants, medicinal plants medicine, plantation industry, and forestry.
