Description of Hemp Stalk and Root System


supplied by Canadian Hemp Industry

Hemp is an annual and a member of the Cannabaceae family which consists of two accepted genera, Cannabis (hemp) and  Humulus (hops).  Industrial hemp is a distinct crop type of the plant species Cannabis sativa L.. Industrial hemp is distinguished from narcotic hemp by having a THC (delta - 9 - Tetrahydracannabinol) level less than 0.3%.  

Other characteristics typical of hemp are 
slender stems, 
plant height ranging from four to fifteen feet and a 
stem diameter from 1/4" to 3/4". 

The innermost layer of the stem is called the pith. 
It is surrounded by a woody material known as hurd. 

Outside of this layer is the growing tissue which develops into hurd on the inside and bast fibers on the outside.

Stem Cross SectionStem Cross Section
The amount of stem branching is inversely related to plant density, ie lower plant densities promote more branching.  The leaves are of a palmate type and each leaf has seven to eleven leaflets with serrated edges. 






The root system generally consists of a dominant taproot and some lateral roots. Soil type will affect which root type will be more developed. For example, in poorer soils the lateral roots will be more developed and the taproot will be short.

Industrial hemp exhibits a dual response to day length. Increasing day length during the first two to three months promotes more vigorous vegetative growth. Later in the season, the plants require shorter day length to trigger flowering and maturation.


Q Toxins Phytoremediation per Acre wtih Hemp




This document (link below) talks a lot about the Sunflowers that was mentioned by.


I'm sharing this information as it will be used as a good example of how prior testing plots are done, suggestions on best procedures, to be used as a comparison model, and mostly to use the EPAs own words: 
Phytoremediation is a suggested low financial cost and way to assist in the removal of toxins from the soil.  

While bigger undertakings are developed and financed.
  • Note: Hemp was not factored into this study for comparison.
  • A lot of attention was given to Sunflowers.  Sunflowers were suggested by 


I'm Seeking Information on:


The amount of Toxins hemp can absorb on a per acre basis.  

If I can't find that info that will be one of the things that we test for on this project

Here is a soil survey of all the toxins and contaminants in the soil at Bridgeton Landfill

In this document the EPA states:

 Phytoremediation can be utilized while the more costly solutions and bigger financial needs are allocated.
