why mycorrhizae is necessary for agriculture - dora agri-tech

why mycorrhizae is necessary for agriculture - dora agri-tech

There is no doubt that bio fungicide mycorrhizae play an important role in plant growth. They help build soil aggregate structure to provides plant roots with a better & healthy environment to healthy and strong growth. Their symbiotic relationship with plants helps them access extra water and nutrients sources in soil.

Mycorrhizae is a symbiotic association between a fungus and a plant. The term mycorrhizae refers to the role of the fungus in the plants rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil microenvironment.

Mycorrhizal fungi have existed more than 450 million years, they appeared at the same time as the first plants appeared on dry land. Myco literally means fungus and rhiza means root, they form a network of filaments that associate with plants root system and develop a symbiotic association called mycorrhiza, thus plants and mycorrhizal fungi make up a single working network in nature.

A mycorrhiza grows after the germination of a fungal spore. From this spore emerge threadlike organisms that gradually penetrate the root epidermis (form hyphae). This creates a symbiotic relationship increasing the plants ability to uptake fixed nutrients and water, improving plant performance.

Mycorrhizal fungi increase the surface absorbing area of roots 100 to 1,000 times, thereby greatly improving the ability of the plant to access soil resources. Mycorrhizal fungi increase nutrient uptake not only by increasing the surface absorbing area of the roots but also release powerful enzymes into the soil that dissolve hard-to-capture nutrients, such as organic nitrogen, phosphorus, iron and other tightly bound soil nutrients.

Endomycorrhizal fungi are one of the major types of known mycorrhizae. Unlike ectomycorrhizae which form a system of hyphae that grow around the cells of the root, the hyphae of the endomycorrhizal not only grow inside the root of the plant but penetrate the root cell walls and become enclosed in the cell membrane as well.

This makes for a more invasive symbiotic relationship between the fungi and the plant. The penetrating hyphae create a greater contact surface area between the hyphae of the fungi and the plant. This heightened contact stimulates a greater transfer of nutrients in plants.

Ectomycorrhizal fungi do not penetrate into the root cell walls, they form a sheath around the root known as a fungal mantle as a nutrient exchange network. Ectomycorrhizal fungi only colonize the roots of trees including species from the birch, dipterocarp, myrtle, beech, willow, pine, and rose families.

Mycorrhizae induce plants to absorb more nutrients and water from the soil. They also increase plant tolerance ability to various bad environmental stresses. In addition to this, Mycorrhizae also play an important role in the soil structure process and stimulate beneficial microbial activity.

Nigeria, country located on the western coast of Africa. Nigeria has a diverse geography, with climates ranging from arid to humid equatorial. However, Nigerias most diverse feature is its people. Hundreds of languages are spoken in the country, including Yoruba, Igbo, Fula, Hausa, Edo, Ibibio, Tiv, and English. The country has abundant natural resources, notably large deposits of petroleum and natural gas.

The national capital is Abuja, in the Federal Capital Territory, which was created by decree in 1976. Lagos, the former capital, retains its standing as the countrys leading commercial and industrial city.

Modern Nigeria dates from 1914, when the British Protectorates of Northern and Southern Nigeria were joined. The country became independent on October 1, 1960, and in 1963 adopted a republican constitution but elected to stay a member of the Commonwealth.

Nigeria is bordered to the north by Niger, to the east by Chad and Cameroon, to the south by the Gulf of Guinea of the Atlantic Ocean, and to the west by Benin. Nigeria is not only large in arealarger than the U.S. state of Texasbut also Africas most populous country.

In general, the topography of Nigeria consists of plains in the north and south interrupted by plateaus and hills in the centre of the country. The Sokoto Plains lie in the northwestern corner of the country, while the Borno Plains in the northeastern corner extend as far as the Lake Chad basin. The Lake Chad basin and the coastal areas, including the Niger River delta and the western parts of the Sokoto region in the far northwest, are underlain by soft, geologically young sedimentary rocks. Gently undulating plains, which become waterlogged during the rainy season, are found in these areas. The characteristic landforms of the plateaus are high plains with broad, shallow valleys dotted with numerous hills or isolated mountains, called inselbergs; the underlying rocks are crystalline, although sandstones appear in river areas. The Jos Plateau rises almost in the centre of the country; it consists of extensive lava surfaces dotted with numerous extinct volcanoes. Other eroded surfaces, such as the Udi-Nsukka escarpment (see Udi-Nsukka Plateau), rise abruptly above the plains at elevations of at least 1,000 feet (300 metres). The most mountainous area is along the southeastern border with Cameroon, where the Cameroon Highlands rise to the highest points in the country, Chappal Waddi (7,936 feet [2,419 metres]) in the Gotel Mountains and Mount Dimlang (6,699 feet [2,042 metres]) in the Shebshi Mountains.

The major drainage areas in Nigeria are the Niger-Benue basin, the Lake Chad basin, and the Gulf of Guinea basin. The Niger River, for which the country is named, and the Benue, its largest tributary, are the principal rivers. The Niger has many rapids and waterfalls, but the Benue is not interrupted by either and is navigable throughout its length, except during the dry season. Rivers draining the area north of the Niger-Benue trough include the Sokoto, the Kaduna, the Gongola, and the rivers draining into Lake Chad. The coastal areas are drained by short rivers that flow into the Gulf of Guinea. River basin development projects have created many large man-made lakes, including Lake Kainji on the Niger and Lake Bakolori on the Rima River.

The Niger delta is a vast low-lying region through which the waters of the Niger River drain into the Gulf of Guinea. Characteristic landforms in this region include oxbow lakes, river meander belts (see meander), and prominent levees. Large freshwater swamps give way to brackish mangrove thickets near the seacoast.

Soils in Nigeria, and in Africa generally, are usually of a poorer quality than those in other regions of the world. However, over the centuries Nigerians have utilized agricultural techniques such as slash and burn, intercropping, and the use of shallow planting implements to cope with the shortcomings of the soil. In the precolonial period the country normally produced enough agricultural commodities to feed its population, and it even maintained a surplus for export.

Nigerias major soil zones conform to geographic location. Loose sandy soils consisting of wind-borne deposits and riverine sands are found in the northern regions, although, in areas where there is a marked dry season, a dense surface layer of laterite develops, making these soils difficult to cultivate. The soils in the northern states of Kano and Sokoto, however, are not subject to leaching and are therefore easily farmed. South of Kano the mixed soils contain locally derived granite and loess (wind-borne deposits). The middle two-thirds of the country, the savanna regions, contain reddish, laterite soils; they are somewhat less fertile than those of the north because they are not subject to as much seasonal drying, nor do they receive the greater rainfall that occurs in the more southerly regions. The forest soils represent the third zone. There the vegetation provides humus and protects it from erosion by heavy rainfall. Although these soils can readily be leached and lose their fertility, they are the most productive agriculturally. Hydromorphic and organic soils, confined largely to areas underlain by sedimentary rocks along the coast and river floodplains, are the youngest soil types.
