Repeated soil sampling has recently been shown to be an effective way to monitor forest soil change over years and decades. To support its use, a protocol is presented that synthesizes the latest information on soil resampling methods to aid in the design and implementation of successful soil monitoring programs.

Source: Nicholas Timmons, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA The goal of this experiment is to test the concept of the conservation of momentum. By setting up a surface with very little friction, collisions between moving objects can be studied, including their initial and final momenta. The conservation of momentum is one of the most important laws in physics. When something is conserved in physics, the...

What is Conservation Biology?

2019
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials. Ecosystems also perform critical services, such as purifying our air and water. A large body of evidence indicates that such ecosystem services depend on biodiversity. Furthermore,...

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Electrostatic Method to Remove Particulate Organic Matter from Soil

Removing recently deposited and incompletely decomposed plant material from soil samples reduces the influence of temporary seasonal inputs on soil organic carbon measurements. Attraction to an electrostatically charged surface can be used to quickly remove a substantial amount of particulate organic matter.
FAQs
Vegetation cover protects the soil surface from direct exposure and helps limit the removal of topsoil by wind or water. It also reduces surface runoff, allowing more water to remain available within the soil rather than moving rapidly across it. Maintaining plants is therefore central to stabilizing soil and supporting productive ecosystems and agriculture.
Increasing organic matter helps maintain soil structure, which supports water retention and reduces declining fertility. These effects make the soil better able to sustain biological activity and plant growth over time. Organic matter management therefore connects physical soil stability with ecosystem function, helping conservation efforts preserve productive conditions rather than only preventing visible erosion.
Contour farming and terracing reduce the movement of water across sloping land by changing how runoff travels over the soil surface. This limits the transport of topsoil by water and helps stabilize the soil. They are especially relevant where surface runoff threatens soil structure, fertility, or the continued productivity of agricultural areas.
Protecting soil preserves habitats for microorganisms, plants, and soil animals. These organisms contribute to nutrient cycling, while healthy soil conditions also support water retention and plant growth. By maintaining these biological relationships, Soil Conservation can strengthen ecosystem resilience and help preserve biodiversity rather than treating soil only as a medium for agricultural production.
The overview identifies several complementary practices: maintaining vegetation cover, increasing organic matter, reducing surface runoff, using contour farming, building terraces, applying mulch, and rotating crops. Together, these measures address erosion, nutrient loss, compaction, and declining fertility from different directions. Their shared purpose is to stabilize soil while sustaining long-term agricultural productivity.
Crop rotation is one of the practices used to support soil conservation and maintain fertility over time. Within the broader strategy, it complements vegetation cover, mulching, contour farming, and terracing rather than replacing them. Combining these approaches helps address several pressures at once, including nutrient loss, erosion, and declining soil quality in productive ecosystems.
In biology, conserved soil functions as habitat for microorganisms, plants, and soil animals, allowing nutrient cycling and water retention to continue. These functions support biodiversity and improve ecosystem resilience under changing environmental conditions. Soil Conservation therefore has value beyond crop production: it helps maintain the biological interactions and habitat conditions on which functioning ecosystems depend.
