Most Maine soils are acidic, and have a somewhat depressed ability to hold and exchange nutrients used by plants. Our native plants evolved in this system, and are well adapted to Maine soils. However, we often amend Maine soils by adding organic matter, lime and/or fertilizer, in order to increase the productivity of our food and landscape plants.

Does Soil Affect Plant Growth? | Reference.com

Does Soil Affect Plant Growth? Plants rely on 13 mineral nutrients found in soil to survive and grow; therefore, the type of soil used for a plant directly affects its growth. If there are not enough nutrients in the soil for a plant to grow, it dies.

Soil - Wikipedia

The physical properties of soils, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity. Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand, silt, and clay.

Soil Structure: The arrangement and organization of soil particles in the soil, and the tendency of individual soil particles to bind together in aggregates; Aggregation creates intra-aggregrate and inter-aggregate pore space, thereby changing flow

Soil pH - Wikipedia

Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions (H + or, more precisely, H 3 O + aq) in a solution.In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as 0.01 M CaCl 2), and normally falls between 3 and 10, with 7 being neutral.

5.4 Weathering and the Formation of Soil – Physical Geology

The types of weathering that take place within a region have a major influence on soil composition and texture. For example, in a warm climate, where chemical weathering dominates, soils tend to be richer in clay. Soil scientists describe soil texture in terms of the relative proportions of sand, silt, and clay, as shown in Figure 5.14.

Martian soil - Wikipedia

Martian soil is the fine regolith found on the surface of Mars. Its properties can differ significantly from those of terrestrial soil, including its toxicity due to the presence of perchlorates. The term Martian soil typically refers to the finer fraction of regolith. On Earth, the term "soil" usually includes organic content.
