Buffer zones and buffer strips are the areas between aquatic and terrestrial zones. The best-known buffer strips are wetlands and riparian zones. They can consist of natural or planted vegetation and serve as a place for water and matter storage. The two types of limitations that impact buffer zones are internal limitations and external … Continue reading buffer zones & buffer strips – what they are and why we need them
Plant tolerance is the characteristic of a plant that allows a plant to avoid, tolerate or recover from attacks from insects, among other things, under conditions that would typically cause a greater amount of injury to other plants of the same species. These inheritable characteristics are what influence the ultimate degree of damage caused by … Continue reading question: what is the difference between plant resistance and plant tolerance?
A disease, as it relates to plants, is a disturbance from plant pathogens or environmental factors that interfere with plant physiology. When a disease is present, plants will express symptoms. Symptoms are the detectable expression of a disease, pest or environmental factor. These symptoms are usually the result of complex physiological disturbances.

Irrigation systems offer a variety of benefits. They allow for the growth of a wider variety of crops. They can be timed so that the hands-on portion of crop production is a little less cumbersome. They protect crops from irregular and dry weather conditions. They support leaching, which can remove harmful, crop-damaging salts within in … Continue reading 8 essential questions to ask before installing an irrigation system
Soil. A living, breathing fundamental component of the world. Without it, we would not be able to grow food. There would be no trees and plants growing to provide us with the delicious oxygen so necessary to our existence. Our water would not be purified. We would more or less just be screwed. Yet, we … Continue reading soil sealing: what it is and why it’s important
We have all read about them…the insane, previously unseen and completely out of control fires that are ravaging parts of America’s west. The lack of water has taken its toll. Reservoirs are tapped. Rivers are running dry. Famous people are illegally hoarding water. Lakes are at all-time lows. Northern parts of states are at odds … Continue reading the benefits of fire

Of course, there is valid evidence demonstrating … Continue reading question: why are humans reluctant to take global warming seriously?
Eutrophication is a process caused by excess phosphates and nitrogen which creates algae blooms. Fast-growing algae die each year and sink to the bottom of the floor of a given body of water. Here it turns into an incredibly rich mud where bacterial decayers thrive. Due to their unnatural quantities and massive appetites, the oxygen … Continue reading eutrophication, choking the life out of a body of water near you?
