Origin, Nature and Biological Activity of Aliphatic Substances and Growth Hormones Found in Soil,oil. These may affect the growth of plants directly and indirectly by modifying the soil environment or the balance of other organisms, such as pathogens, present in the soil. In an earlier review., I catalogued some of the products and outlined some of the conditions which must be satisfied to be c

The Soil Biomass,anic substrates are largely governed by the activity of the soil biomass. Inhibition of microbial activity by a low or high temperature, drought, waterlogging, extremes of pH or xenobiotic substances may result in the persistence in soil of potentially decomposable and mineralizable compounds with s

Soil Phosphorus, and ADP (adenosine-5′-diphosphate) from inorganic orthosphosphate (P.). Phosphate derivatives are also involved in almost all significant metabolic pathways, as well as being present as a structural component of many biochemicals including nucleic acids, coenzymes, phosphoproteins and phospholipids

Sulphur in Soils and Plants,phyll, glucoside oils, and in structurally and physiologically important sulphide linkages in cell walls and sulphydryl groups of enzymes.. In recent years, however, sulphur has received more attention due mainly to reports of sulphur deficiency in crops, to concern over the effects of acid rain, an

Organic Matter and Trace Metals in Soils,oncentration of the element in solution, and the . which is the ability of the solid phases in the soil to replenish the nutrient element as it is depleted from the solution. The fundamental relationship between intensity and capacity factors depends on the solubility relationships between soil mine
