Mineralization in soil science is the decomposition (i.e., oxidation) of the chemical compounds in organic matter, by which the nutrients in those compounds are released in soluble inorganic forms that may be available to plants. Mineralization is the opposite of immobilization.
Although several previous reports suggest nitrogen mineralization has the potential to vary seasonally and out of phase with plant production, such a phenomenon has been poorly documented. Here we report results from a semiarid savanna ecosystem characterized by distinct temporal asynchrony in rates of soil nitrogen cycling and plant production.

Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits. Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal. Gold has been the most highly esteemed and sought after precious commodity since the times of antiquity It has spurred on numerous ...
The plants were thinned 1 week after seed germination by keeping 10 healthy plants in each pot. As the plant protection measure pesticide (viz. ripcord, bought from local market) was sprayed as needed. After 7 weeks from the emergence of plants, the plants were harvested by cutting the stems 1-cm above the ground.

mineralization from a range of feeds and faecal materials measured in an incubation experiment. Keywords: decomposition, N mineralization, quality factors, simulation, modelling 1. Introduction The cycling of nutrients through the decomposition of plant residues is important in all ecosystems.
Aerobic Mineralization and Recovery of Nitrogen as affected by Soil Organic Matter organic N, which takes place in the soil (Bernal et al., 1998). Effective management of N presents a greater challenge to the farm operator than does that of any other fertilizer nutrient because it can enter or leave the soil-plant

because mineralization, which is dependent upon the quality of organic materials, environmental factors and proportions (Palm et al., 2001), will have to occur in order to release inorganic N into the soil before plant can utilize. Research in western Kenya showed that .
Mobilization and Mineralization. Mineralization and Immobilization – Healthy plant hormones are increased, as well as the storage of soil carbon, greatly increasing nitrate nitrogen availability to plants. This creates a nutrient reservoir plants can access, comprised of organic bio-stimulants in the soil.

deficiencies in Kenya often occur simultaneously with those of P and K (Jama et al., 1998). Few studies have, however, investigated the mineralization of these two major nutrients simultaneously with that of N. The objective of this study was to determine decomposition and N, P and K release patterns for pymarc and examine how this varies

It has been proven that when this fungus has been added to potted plants, where the only difference was the addition of the fungus to one of the two plants, the one with the fungus did remarkably better than the one without. The addition of this fungus is easy, just find a forest and dig down a bit.
Gross rates of ammonification were measured over 9 days by 15 N isotope dilution techniques allied to a mathematical model in an Orthic Ferralsol from Kenya. Rates of mineralization in soils conditioned for 24 days at different constant gravimetric moisture contents increased from 0.08 μg −1 Ng −1 d −1 for both ammonification and nitrification at −5.91 MPa to 2.12μg Ng −1 d −1 ...
