The place where many normal plantations can not be grown, sometimes even die, however it is the wonder land for Wild plantations. Such as  the rhododendron and cogongrass grow within the red-yellow soil which PH=4.0.

Even the same breed of plantation, due to different strain and growth quantity, has different absorption capability from soil.There are many reasons which will influence this kind of absorption. With years of study, scientists have found something. Moreover, it gives people directions where to go further.

 1. The form of plantation's absorption

 1-1. Root is the foundation of plantations. It helps with the absorptions of water and nutritions, stimulates the Synthesis of Plant Growth Regulator and others. Let's take an inside looking into the absorption of water and plantations. The surface area and density of roots decide the absorption of water and nutritions. However, the form the root such as the length of roots, quantity of branch roots, quantity of roots hair and tips, all of them adding up has great influence towards the absorptions of water and plantations.

 1-2. Stem and leaves  not only will them influence the absorptions by its form, position and angle, but also influenced by the Photosynthesis.  The different level of Photosynthesis makes different level of consuming degree during the process of absorptions. With this ripple effects, it also influences the root activities.

 2. The biochemistry characters of plantation's absorption

 2-1. Ion-exchange of Root. Root has strong ability of ion-exchange. The ion-exchange capacity influence the plantations' nutrition absorptions. With the growth of ion-exchange, the absorption also goes higher than normal.

 2-2.Enzymatic activity  The absorption of plantation is a dynamic process. It based on the metabolism demands to proceed selective absorption. In this condition, The enzymatic activity shall definitely make influence towards the plantation's nutrition absorption.

 2-3.PGR and Plant Toxin, the small contained elements sometimes have its huge effects towards plants. Such as auxin, Kinetin,Indoleacetic acid and other PGR and Plant Toxin.

All in all, we spend time, efforts, budgets towards the field and seeds. However, no matter how much budgets we spent, how much efforts we put and how much time we consumed, it could not be working if we are doing it in an incorrect way.
