It also includes recommendations of fertilizers that can be applied to remedy nutritional deficiencies. These features and more make Handbook of Plant Nutrition, Second Edition a practical, easy-to-use reference for determining, monitoring, and improving the nutritional profiles of plants worldwide. Plants get nutrition and water from the soil, and the better the soil, the more able they are to grow. Soils are a mixture of components; different types of particles (eg. sand, clay, organic matter), air pockets, water and living organisms (eg.bacteria, earthworms). The roots of plants then grow in amongst all of these components. The world

An additional, important source of salts in many landscape soils comes from ice melters used on roads and sidewalks. The addition of virtually any soluble material will increase soil salinity. It is only when salts are present in relatively high amounts that plant growth is adversely affected. …, Soils under such climatic conditions contain a low organic fraction. The uncultivated sandy soils contain as little as 0.008-0.015% organic matter; therefore, their total N content is also low, 0.0015-0,002%. In addition to their low content of N, the leachability of N fertilizers in these soils constitutes a major nutritional problem..

Salt-tolerant plants are more able to absorb water from saline soils. Salt-sensitive plants have a limited ability to adjust and are injured at relatively low salt concentrations, bacteria in anaerobic soils convert nitrate into gaseous nitrogen or nitrous oxide. Leaching of nitrates from vulnerable soils is also responsible for important losses of soil nitrogen, especially when soils are left bare after harvest, rainfall is heavy and temperatures are low (which reduces the conversion activity of the soil bacteria)..
