Fahalovan’ny vato fototra TANY FAMBOLENA Singa mineraly fikikisan’ny rivotra fikikisan’ny rano Fahalovan’ny vato fototra Vato sy vatokely (> 2 mm) fasika (0,05 - 2mm) dilatra (limon) (0,002 - 0,05 mm) tanimanga (< 0, 002 mm) Mineral Particles Soil consists of mineral particles, organic matter and pores. Mineral particles originate from subsoil and rock, which gets crushed to smaller and smaller pieces through physical and chemical weathering processes.   The mineral soil particles are divided into four groups according to their size: - Gravel and stones: particles larger than 2 millimetres - Sand: particles from 0.05 to 2 millimetres; they can be felt between the fingers - Silt: particles from 0.002 to 0.05 millimetres - Clay: particles smaller than 0.002 millimetres The difference between sand, silt and clay is not visible to the naked eye. Still it is important to distinguish between them, as the properties of the soil is very much dependent on the composition of the different particle sizes. Soils having equal amounts of clay, silt and sand are ideal for agricultural use. Such a soil is called loam. Mineral particles contain nutrients which are slowly released in the process of weathering. Plant roots and some micro-organisms can actively dissolve nutrients from mineral particles and use them for their growth. The plants need minerals to build up organic matter and for physiological processes.
