Solarisation application by mulching the soil with a polyethene plastic film has a significant influence on soil thermal characteristics TCs , which, in turn, show a strong impact on soil energy balance and agricultural productivity. In countries like Iraq with highly populated cities, such as Baghdad, that need large quantities of agriproducts, this kind of clean energy should play a key role in sustainable agricultural production.

Most of us think of the soil as the natural habitat for plants, and therefore soils must provide a nurturing and supportive environment for them, right? Well…most of us could not be more wrong about that. The soil is not a very welcoming environment for plant growth. It does not provide everything a plant needs freely and without reservation. In fact, left as is, the soil probably would not produce very many plants at all. Proof of this is found in the tremendous amount of soil modification plants engage in just to improve their chances of survival. Plants modify soil. That is a fact. They spend a lot of energy doing it, and they do it to their own advantage.

Plants modify the soil chemically, biologically, and physically in very substantive ways. This blog entry focuses mostly on the physical side of things by considering how root structures affect the soil. Root structure is called root architecture. The term can include physical arrangement of roots, number, thickness, length, depth, angles of branching, and distribution of root orders.

Different plants have different root architectures. We do know that roots are the primary means for resource acquisition by plants, that they release many complex chemical compounds into the soil that affect carbon storage and influence other soil organisms, and that they leave the soil changed after the interaction. An easy place to get started with understanding root architecture is the concept of root order. In image 1, we have a young mustard plant excavated from field, its roots washed free of soil. The largest central root is the primary or seminal root.

A root that branches off the seminal root is classified as a first order lateral. A root the branches from a first order lateral is classified as a second order lateral. This may continue, but usually not too far, because small roots tend to begin producing the very fine root hairs that maximize surface area to volume for the uptake of water and nutrients.

Another basic idea in root architecture is that there are two basic types of root systems, the tap root system, and the fibrous root system.

The mustard plant in Image 1, above, features a tap root system with a dominant and easily recognizable downward growing single root from which branch all the other roots. In a fibrous root system Image 2such as that of the corn plant, there are many kf seminal roots and often no clear single primary root. You can see that the roots develop from the stem, rather from a downward growing root.]
