Top 3 Approaches used in Soil Pest Management
Soil pest control is a preventive agricultural practice that implicates biological, mechanical, chemical, and physical control techniques to reduce pests in the soil.
Although combined soil pest management has different methods, we’re going to discuss the three most typical ways shown below in this artickle.

Top 3 Methods applied in Soil Pest Management
This can be noted from the above description, soil pest management’s primary goal is to eliminate or decrease the population of pathogens in the soil. I know some of you may be questioning what kind of pests exist on earth.
In this consideration, here are some of the most typical fungi and bacteria that live in the soil. Never observe their names.
- Verticillium and Rhizoctonia
Although some pathogens may be useful in soil aeration, most of these organisms that occupy the soil can cause considerable losses in crop production. Let us look at the above techniques used to combat soil pathogens.
Biofuigation is a soli administration practice that involves applying a large amount of organic material to the soil. This method requires 5kg per meter square of organic matter.
This approach aims to generate a gas that results from the decomposition of organic material to prevent soil pathogens. This natural material can be fresh waste from animals or crops after harvest.
How does this work?
It is easy; the decomposition of the organic matter will release ammonia gas in animal manure. Recall, the fresher the slurry, the higher the emission of ammonia.
If you select to use crop manure, isothiocyanates molecules are released into the soil. On the other hand, if the organic weight is harvested from cruciferous vegetables, it will deliver ammonia and phenols.
I hope you are not thrilled at the choice of big words; I can’t describe them in simple terms and believe that you get the idea.
Moving on, the fumigant movement resulting from the decomposition of this matter is usually choosy.
Because the volume of the gases liberated in the biofumigation process necessary to kill the pathogens is roughly thirty times less than that needed to affect pathogen-antagonistic fungi. 🙂
Soil Pest Management – Solarization
The solarization pest control technique is merely mulching the soil in a specific way.
To use this method efficiently, a translucent plastic cover(paper bag) on top of the mulch during hot, moist conditions to help increase the soil’s temperature.
Solar radiation from the sun penetrates through the plastic cover and is converted into the warmth and transmitted to the soil.
The soil, nevertheless, does not emit back the radiation into the plastic sheet. Therefore higher temperatures are attained.
Chemical, physical, & biological changes take place. Which, in turn, causes the decline or disappearance of a large number of soil pathogens.
On the other hand, it’s equally important to note that this method’s success largely relied on radiation and temperature.
With this in mind, pathogens pass in the soil rapidly at temperatures of 50ºC. The time-critical to cause these deaths depends on the species in question and the sensitivity and heat resistivity of the species.
The last method used in soil pest control is Biosolarization, which combines two methods.
This combination gains higher temperatures than those created with classical solarization and accumulates a more significant amount of gases under a single roof.
