Literature Review

This chapter relates to the impact of microwave energy on soil biota in order to understand how to continuously explore the commercial value of microwave energy in promoting green agriculture and promote productivity.

Firstly, it is required to understand relevant knowledge regarding differences between microwave energy and conventional energy so as to understand a more essential role of microwave than conventional energy to interact with soil biota.

Hypothesis 1: Microwave energy is more efficient and uniform when heating than conventional energy to guarantee the quality of products.

Essentiality of Microwave energy

Microwave is an effective heating technology which is beneficial in applying in the agricultural field. Relevant studies have been conducted in relations to the role of microwave techniques in the agricultural process. Kraszewski and Nelson (2003) state that microwave energy can be utilized to improve the efficiency of crop production, handling and processing to improve the quality of products. In Brodie (2012), ‘most agricultural and forest products are a heterogeneous mixture of various organic molecules and water, arranged in various geometries’. As illustrated by Moskovskiy et al (2012), using microwave energy has many characteristics which will be listed as follows:

1) High efficiency of conversion of microwave energy into thermal energy ( close to 100%);

2) ‘with persistence’ heating of the object, “inside” with extremely high intensity to control temperature and speed;

3) Contactless eco-clean supply of energy;

4) Uniform heating across the mass of the product and its selectivity in the case of inequality of the dielectric properties;

5) Reduction of time and energy consumption during the process;

Herein, these are specific features contained within microwave energy to confirm the essentiality of microwave in better control temperature and speed. Using microwave is better to manage the heating process to prevent uncertainties while effectiveness can be optimized (Kim et al, 2011). Continuously, it is the comparison and contrast between microwave heating and conventional heating to understand more strengths of microwave method than the traditional engagement.

The above figure reveals different operating process between microwave heating and conventional heating.

1) The microwave heating process is fast than the traditional model to reach a higher temperature inside the product;

2) microwave heating leads to the uniformity of warming across the product to ensure the temperature regulation can be conducted effectively;

3) Materials can be treated properly since the electromagnetic wave does not depend on the thermal conductivity which also will not be affected by the outside environment;

4) Products which heated via microwave will have better quality to improve their competences and salabilities;

5) There is no direct connection between the heating source and products which required to be heated;

6) Better control during the process of heating or drying;

7) Reduce costs and be more environmentally friendly;

Regardless of the involvement effectiveness, speed, quality and other relevant function, implementing microwave will be ideal in satisfying needs in the modern society. microwave can be regarded as a more high-tech driven technology than using traditional approach to make the entire heating process more practicable. It does not deny that conventional heating methods will be unavailable. Zhu et al (2013) put forward that selecting microwave energy is more beneficial to satisfy social, environmental and economic objectives. Microwave techniques maybe more appropriate to suit needs in the contemporary society to increase convenience to reduce time consumption (Varma, 2013). In Varma (2013), microwave energy is more environmentally friendly centric so that less pollution will be caused during the entire process. Moreover, via the highly efficiency of engaging in microwave process, more economic advantages can be gained due to the reduction of other costs such as time or the volume of energy consumption (Varma, 2013). Therefore, it is essential to confirm microwave will be better than conventional technologies in participating in social, environmental or economic activities in the modern society. Herein, contents of hypothesis 1 can be certified.

Following that, it will be a more important discussion in relation to the impact of microwave on soil biota in order to certify microwave energy generates positive influences on soil biota. That is, using microwave  energy is more helpful to manage soil process so that agricultural productivity and quality can be enhanced.

Hypothesis 2: microwave energy has the critical role in improving the soil ecosystem management so as to promote quality production while reduce pollution.

A Healthy Soil Ecosystem

It is important to understand that only if in a healthy soil environment, the quality of products can be guaranteed after planting. Health crops and healthy animals should depend on offering them a healthy soil environment. Thomsen, Faber and Sorensen (2012) describe features of a healthy soil environment include:

1) In spring, water permeability of the soil is strong which can be heated up easily;

3) The absorbing ability of raining is strong to prevent draining;

4) In dry seasons, healthy soil can keep moisture;

6) Supply abundant microorganisms;

7) Do not need repeated input more manures to keep the yield;

8) Produce healthy, high quality crops;

In Kraszewski & Nelson (2003), a healthy soil ecosystem means the precondition for a sustainable agriculture. In a healthy soil environment, the survival capability of soil biota can be promoted, accordingly, it will be beneficial to transform, create or modify habitats for relevant products (Kraszewski & Nelson, 2003). Soil biota is an important compound within a natural system to ensure the sustainable agroecosystems to be formed (Callaway et al, 2004). In Callaway et al (2004, p. 731), ‘soil microbes have profound negative and beneficial effects on plants’, continuously, ‘these different effects enable to cause dynamic feedback interactions between plants in the microbial community’. It has the implication that without effective management of soil biota, exotic plants may invade to damage the agricultural environment. In other words, whether impacts caused by microwave energy can be considered as positive to develop green agriculture should rely on the benign interaction between microwave energy and soil microbes. Therefore, it is also important to understand the importance of biodiversity management in the soil process in order to better promote positive interactions between microwave energy and soil biota.

Biodiversity Management  400

Nonetheless, the biodiversity cannot be avoided within the soil ecosystem, that is, the establishment of a healthy soil environment should depend on the effectiveness of biodiversity management.

Effective biodiversity management has advantages to offer proper ecosystem services in satisfying needs of diverse soil organisms.

Via managing soil diversity, ecosystem integrity can be improved to promote quality productivity.

Through biodiversity management, aboveground-belowground interactions between diverse organisms can be effective managed to improve the land productivity.

The Significance of Microwave Energy in Biodiversity Management 400

Microwave energy is an effective tool to enhance the effectiveness of biodiversity management.

Microwave technology helps to create an inclusive soil environment for diverse soil organisms coexist harmoniously.

Impacts of Microwave Energy on Soil Biota   600

Microwave technology enables to promote both production and reproduction of soil biota to help them grow healthily.

Microwave heating helps to effectively remediate contaminated soil to reduce pollution while promote green agriculture.
