Imagine walking out into a crop field or pasture. What do you notice? Perhaps you see amber waves of grain out to the horizon or hear the leaves rustling in a cool breeze. But would you ever think about what's beneath your feet? What lurks in that hidden world, and why does it matter to you?

As you look at all the growth aboveground, you might consider that just as much plant mass is invested in roots. In fact, in the springtime, 1 acre of grassland or pasture may have about 1,000 pounds of standing shoot mass aboveground but as much as 3,500 pounds of roots below ground, in the top foot of soil.
Roots' Role
Plants are like a factory, using energy from sunlight to produce sugar in their leaves that provides the carbon backbones for making all the other molecules required for life. In order to build more leaves with their green chlorophyll, plants need to send their roots out into the soil to forage for water and mineral nutrients such as nitrogen and phosphorus. These nutrients are required for making proteins, like chlorophyll, and to fuel the molecular energy system in the form of adenosine triphosphate (ATP). Also, DNA itself requires phosphorus. Once a new leaf is built, water from the soil is taken up by the roots and eventually evaporates from the leaves. Essentially, the whole plant is acting like a straw, with the tips of the roots taking up water from the soil.
Improved Root Design
When pondering how to optimize root systems, we have to think carefully. More roots are not always better. Roots are built from the carbon gained during photosynthesis, meaning they represent a construction cost. All those roots also require carbon for normal operations such as respiration, which is the maintenance cost.
Therefore, optimizing root systems requires both engineering and economic principles about how to efficiently explore soil with as few roots as possible. In fact, many human factories use this marginal value theorem from economics to decide which parts of the factory to invest in, always maximizing the investment's profit per unit cost.
Most of the Maple trees have roots as deep as 12 to 18 inches from the soil surface and spreading up to a distance of 25 ft. As the tree grows in size, these roots sometimes come out of the surface. The roots present near the surface can also cause damage to the concrete sidewalks, porches.
Designing better roots is an important avenue for helping people. With better roots, we can increase yield, reduce fertilizer use and pollution, and promote soil health.
In basic research and breeding programs at the Noble Research Institute, we consider aspects of root system architecture including root angles, number of axial roots, lateral root branching density and root diameters. We use image-based plant measurement, or phenotyping, among many other approaches.
Benefits of Better Roots
However, roots don't matter only to the plant. In fact, roots are central to soil health, which ultimately relies on the photosynthetic abilities of plants to provide food to the entire ecosystem. As roots explore, they release sugars, organic acids and other compounds into the soil during the exudation process. Through this process and others, soil around the roots becomes a special place called the rhizosphere (rhizo means root in Greek). These organic compounds can promote beneficial soil microbes, such as bacteria and fungi, and inhibit plant pathogens. Beneficial soil microbes increase carbon and nutrient cycling in the soil, ultimately benefiting plants.
As roots die, the entire organ becomes dinner for the microbial community along with other soil creatures like worms and insects. All these root-derived inputs are fundamental to creating and storing soil carbon and are a driving force for soil health, as increased soil carbon allows for better water infiltration and storage in pastures and fields.
Designing better roots is an important avenue for helping people. With better roots, we can increase yield, reduce fertilizer use and pollution, and promote soil health. At the Noble Research Institute, we are screening natural diversity for root traits in several crop and pasture species; with the creation of new knowledge, we will include these traits in breeding programs to release new cultivars with improved root systems.
So, the next time you're outside admiring the beauty aboveground, don't forget there is an equally beautiful and complex world under your feet.
A root system is part of the plant that holds it to the ground and supply water and other essential nutrients. All the complex formed by the roots of a plant is called the root system…
Types of Root System
Three types of main root systems are found in nature as
- Taproot system
- The fibrous root system and
- Adventitious root system.
Taproot system
In this root system, there is a primary root that grows directly from the radicle. It forms a dominant central axis and is thickest of all the roots.
It grows downwards into the soil tapering towards the apex and helps the plant gain immense support.
The secondary roots are the root branches that grow out from the taproot. These secondary roots develop in acropetal (around) succession.
There are also branches from the secondary roots which are called the tertiary roots. These tertiary roots also follow acropetal succession.
The final branches of the root system called rootlets, root caps and root hairs occur over them.
Thus, this tap root system is complex and is present in large trees and shrubs to give them firm support by fixing them deep into the soil.
Examples of plants with such roots are neem, cotton, rose, etc.
Fibrous root system
In this system, a number of fine thread-like branched roots of uniform size bunch out from the base of the stem.
This type of root system occurs in monocots like rice, sugar cane, wheat, etc.
Here the primary root and seminal roots do not persist for long.
Further, these roots unlike taproots do not penetrate deep into the soil. Instead, they are located superficially. Hence, it is easy to uproot the whole plant manually.
However, these plants are not carried away by heavy winds in-spite of superficial roots due to the small size of the plant.
Adventitious root system
This system of the root develops on a plant from places other than the radicle. Adventitious roots may be above or below the ground.
These roots are commonly thin or fibrous. They develop normally from nodes of creeping stems or from places of injury.
As the name indicates, these roots provide additional benefits to the plant.
Besides helping in fixation of the plant into the soil, they help in other aspects based on the plant requirements.

These adventitious roots are of different types like
Prop roots
They develop from the upper part of the stem, usually from the horizontal branches. They travel downwards into the soil vertically. These Prop roots are longer and act as pillars.
These prop roots are thicker and provide additional support to the plant. They can replace the main stem or trunk.
Examples of such plants include the banyan tree.
Stilt roots
These roots are aerial roots and develop from the basal nodes of the main stem. Then they go obliquely downwards into superficial layers of soil.
Stilt roots are shorter and act as tent ropes to provide extra support. Stilt roots are less thick and seldom replace the main stem.
Stilt roots are present in mangrove trees.
Storage roots (Root tubers)
These roots are meant to store reserve food material for the availability of the plant latter.

Roots are modified and enlarged which store food thus acting as storage organs like sweet potato, beetroots, carrot, radish, etc.
These storage roots are of different types on which we have a complete description as types of storage roots.

These are the roots that grow upwards out of the ground. As the name indicates, they are intended to absorb oxygen from the atmosphere.
