Soil salinity is one of the major environmental problems that affect the crop yield, soil health and consequently the socio-economic condition of the farming community. Monitoring the progressive development of soil salinity and assessment of its degree of severity is important to quantify its adverse effect on production and productivity and on environmental degradation. Presently, the monitoring of soil salinity [...]
After reading this article you will learn about the nature and sources of soluble salts found in soil. Nature of Soluble Salts: Soluble salts, as referred to in soil science, are those inorganic chemicals that are more soluble than gypsum (CaSO4.2H2O), which has a solubility of 0.241 gm. per 100 ml of water at 0°C. Common table salt (NaCl) has [...]
This article provides a short note on calcareous soils. Zonal soils of arid regions usually contain sufficient amount of lime (CaCO3) at some horizons of the soil profile. When the zone of lime accumulation coincides with the depth of high root concentration, it may be an important factor in plant nutrition. Many soils are formed from limestone or marl parent [...]
