SOIL ENZYMES AND CHARACTERISTICS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
For understanding the structure and the functions of soil ecosystem, the analysis of soil microorganisms’ population and the factors affecting their activities are important. For this purpose, the soil enzymes: are used as indicators of soil fertility and microbial activity. The distribution of soil enzymes and activities on the agricultural lands under the monoculture or sowing is accepted as a wide research subject however the researches which investigate the ecological relation in natural ecosystem by using the enzymes on biotope characterization are rare or not too much. With this study it was attempted to establish a base for future studies by evaluating the done researches on soil properties and their effects on soil fertility.
Zeros of the Sum of Two Polynomials
In this paper we find bounds for the zeros of the sum of two polynomials whose coefficients are restricted to certain conditions in the framework of Enestrom-Kakeya theorem. Mathematics Subject Classification: 30...
