Grey Ðất Feralit grow on sand stone (Xfq)-Ferralic Acrisols (ACf) Area: 2,651,337 ha Distribution: BAC Giang, Vinh Phuc, BAC Ninh, Nghe An, Quang Binh, the Highlands ... Ðá mother: sandstone, shale, quăczit Silicon Cost of land has some common properties such as the following: motor components in light, sandy soils in the higher rate, the land has no texture or very poor structure. Ground floor is thin, regular thickness < 1 m. Typical soil profiles also have enough 3 the A, B, C; in the B horizon and C contain many quartz crystals left edge. Low humus content, approximately 1% in the soil surface, P2O5 total and easy targets very low (0.02-0.06% and 8.4-0.5 mg/100 g soil), total K2O and low and medium Exchange. Ðất react very sour, pHKCl from 3.8-4.3. In summary the grey soil sand rock development Feralit have many similar grey soil properties Feralit acid magma rock development. The place has a small slope can be used in agricultural production, the rest should be planted forests. Need to implement measures to protect against the degeneration of soil and prevent erosion of soil, manure and moisturising enough to get the land.

Land Developer Feralit gray sandstones (Xfq) - Ferralic Acrisols (ACF)

Area: 2,651,337 ha
Distribution: Bac Giang, Bac Ninh, Vinh Phuc, Nghe An, Quang Binh, the Central Highlands province ...
stones mother: sandstone kinds, quartzite form the substrate, wafer
unit of this land has some general characteristics are as follows: light mechanical components, a high percentage of sand in the soil, soil texture textured or very poor. Thin soil layer thickness typically <1 m.
Typical soil profiles also have full 3 floors A, B, C; B and C floors in floors contain quartz crystals are sharp.
Low humus content, approximately 1% in the topsoil, and P2O5 total digestible very low (0.02 -0.06% and from 0.5 to 8.4 mg / 100g soil), total and handed K2O low and moderate change. The land has a very sour reaction, pHKCl from 3.8 to 4.3. In summary Feralit gray soil developed on sandstones have very similar properties more Feralit gray soil developed on acid magma.
Places with small slope can be used in agricultural production, and the rest should be planting. Should implement measures to protect and fight against land degradation such as soil erosion, sponged enough fertilizer and soil moisture.
