Various Organic Materials

The organic matter added to the soil, usually in the form of fertilizer. Fertilizer is a natural substance that is added to the soil to increase soil fertility. Organic fertilizers are fertilizers that come from nature, from the remains of living organisms both plant residues and animal remains which contain elements of both macro and micro nutrients that are needed by plants in order to thrive. Organic fertilizers are made from materials that are renewable, recyclable, diombak by soil bacteria into usur elements that can be used by plants, without polluting soil and water.
Organic fertilizers can be either liquid fertilizer and solid fertilizer. Liquid fertilizer is usually a sieve of solid fertilizer. Liquid fertilizer is intended to penggunannya easier, does not contain impurities, and also maintain soil moisture. Solid manure can be a green manure, litter manure, compost, and manure. These would be a positive influence on the land if the gift to the ground after the fertilizer.
SOLID FERTILIZER / DRY
Green Fertilizer
Green manure made from plants or plant components are embedded into the ground. The species that is widely used is of familia Leguminoceae or nuts and types of grasses (elephant grass). Type can produce more organic material, absorption haranya larger and have root nodules that helps bind nitrogen from the air. The advantage of using green manures such as
1. able to improve the structure and texture of the soil and water infiltration
2. prevent erosion
3. can help control pests and diseases that come from the soil and weeds if planted during fallow land
4. very useful in areas that are difficult to reach for the supply of inorganic fertilizers

However, green manure also has its drawbacks, namely:

* Greenery can be a constraint in time, energy, land, and water
* On cropping patterns that use crop rotation with legumes can invite pests or diseases
* Competition * with the plant can cause the subject in terms of forging, water and nutrients in the cropping pattern of intercropping.

Fertilizer litter

Litter fertilizer is a waste utilization plant or component that has been unused. For example, hay, straw hump, blow grass, corn cobs, and others. Fertilizer is often called manure litter ground cover due to direct utilization, which was placed over the surface of the soil around the plants (mulch). The role of this fertilizer are:

* To maintain soil moisture, reduce evaporation, water savings
* Prevent erosion, mulch-covered soil surface insoluble and water-borne
* Inhibit the leaching of nutrients to surface waters and
* Inhibit weed growth
* Maintaining the texture of the soil remains crumbs
* Avoid contamination of diseases caused by rain splash
* Facilitate the activities of soil microorganisms that help fertilize the soil and humus source

Compost
Compost is organic material that has undergone weathering, such as straw, reed, rice husks, and others including animal waste. Actually, green manure and litter can be said sebgai compost. But now many of the specifications of the compost. Usually people prefer to use domestic waste or waste derived from plants and renewable materials that are not tercmpur metal and plastic. It is also expected to tackle the mounting trash heaps, and reduces pollution and pollution in urban areas.

Dung
The farmers used to make and use the manure as fertilizer because it is cheap, easy to process, as well as its effect on plants. The use of fertilizers is a manifestation of the incorporation of agriculture and animal husbandry as well as a necessary condition for farming concepts organik.Style Definitions * / p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-parent: “”; margin: 0cm; margin- bottom: .0001 pt; mso-pagination: widow-orphan; font-size: 12.0pt; font-family: “Times New Roman”; mso-fareast-font-family: “Times New Roman”;} p.p1, li . p1, div.p1 {mso-style-name: p1; mso-margin-top-alt: auto; margin-right: 0cm; mso-margin-bottom-alt: auto; margin-left: 0cm; mso-pagination : widow-orphan; font-size: 12.0pt; font-family: “Times New Roman”; mso-fareast-font-family: “Times New Roman”;} @ page Section1 {size: 612.0pt 792.0pt; margin: 72.0pt 90.0pt 72.0pt 90.0pt; mso-header-margin: 36.0pt; mso-footer-margin: 36.0pt; mso-paper-source: 0;} div.Section1 {page: Section1;} -> Manure have the advantage of better properties than other organic fertilizers especially from inorganic fertilizers, which are:
* Manure is humus contains a lot of organic elements that are needed in the soil. Therefore, to maintain soil structure so easily processed and contain a lot of oxygen. The addition of manure to improve soil fertility and agricultural poduksi. This disebakan more land to hold water so that more nutrients will be dissolved and more easily absorbed by the root hairs.
* Sources of macro and micro nutrients in balance is very important notice of plant growth and development. Micro elements that are not found in other fertilizers can be supplied by manure, for example, S, Mn, Co, Br, etc.
* Manure contains many microorganisms that can assist the formation of humus in the soil and synthesize specific compounds that are useful for plants, so manure is a fertilizer that is necessary for the soil and plants and its presence in the soil can not be replaced by other fertilizers.

LIQUID FERTILIZER
Fertilizer oganik not only shaped like a liquid to solid inorganic fertilizers. Liquid fertilizer seems to be more easily utilized by plants because the elements in them have broken down and no amount is too much that it felt faster benefits.
Liquid fertilizer raw materials can be derived from the treatment of solid fertilizer immersion. After a couple of weeks and through several treatment, water immersion can already be used as a liquid fertilizer.
The use of liquid fertilizer can simplify and save energy. The advantages of liquid fertilizer are:
* Workmanship fertilization will be faster
* Its use and conduct watering treatment so as to maintain soil moisture
* Application with organic pesticides serve as a deterrent and eradication of plant disturbance.
