The donor can be an acid, such as nitric acid, sulfuric acid, or carbonic acid. It can also be a compound such as aluminium sulfate , which reacts in the soil to release protons. Acidification also occurs when base cations such as calcium , magnesium , potassium and sodium are leached from the soil.
A soil ball with indigenous worms in soil amended a few weeks previously with bokashi fermented matter. Bokashi is a process that converts food waste and similar organic matter into a soil amendment which adds nutrients and improves soil texture. It differs from traditional composting methods in several respects. The most important are:
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate . Additional chemicals vary depending on the mineral source and may include calcium oxide .
Amelioration of soil structure leading to a reduction of mineralization by means of protecting soil organic carbon. Liming is known to ameliorate soil structure, as high Ca 2+ concentrations and high ionic strength in the soil solution enhance the flocculation of clay minerals and, in turn, form more stable soil aggregates.

Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Soil develops through a series of changes. [2] The starting point is weathering of freshly accumulated parent material.A variety of soil microbes (bacteria, archaea, fungi) feed on simple compounds released by weathering and produce organic acids and specialized proteins which contribute in turn to mineral weathering.
The burning of fossil fuels is the main source of the excess greenhouse gases causing climate change, but there are other sources to consider as well.A special report from the Intergovernmental Panel on Climate Change (IPCC) estimated that, in the last 150 years, fossil fuels and cement production have been responsible for only about two-thirds of climate change while the other third has been ...
The quality of a garden's soil can have a significant influence on a garden's design and its subsequent success. Soil influences the availability of water and nutrients, the activity of soil micro-organisms, and temperature within the root zone, and thus may have a determining effect on the types of plants which will grow successfully in the ...
