In this work we focus on the effects of using different forms of nitrogen uptake kinetic function for the dynamics of Plant-Soil model including Holling type II and III. We present the derivations of these two different type of functional kinetics for the general enzyme-substrate reaction process. For the Plant-Soil Model the local existence and positive invariance of the solution are investigated. Also some conditions to guarantee that the model possesses a unique positive equilibrium point are suggested.

It is a generalization of the concept of magic squares. In this paper we investigate new algebraic structures of PMS’s. We explore the group structure of PMS’s to show that the quotient of the group of PMS’s of order n by its subgroup with zero constant is isomorphic to the infinite additive group of integers, where theisomorphism is constructed by means of the magic constants of the corresponding PMS’s. We investigate the ring structure of PMS’s to characterize nilpotent and idempotent PMS’s as well as we show that the set of PMS’s of zero constant is a two-sided ideal in the ring of PMS’s. Thus, we can define the quotient ring of PMS’s. Moreover, we introduce an invariant and a weak invariant of PMS’s and show some results derived from such definitions. In particular, we show that the set of weak invariants of PMS’s forms a Z-module under the pointwise addition and scalar multiplication.
