Linear aeration is an aeration process that allows water to penetrate the soil and to be retained in the proper amounts. [1] Additionally, it can also add organic nutrition and soil softeners (such as humus, topsoil, compost, sand or clay) if necessary.
Highly maintained areas of grass, such as those on an athletic field or on golf greens and tees, can be grown in native soil or sand-based systems. There are advantages and disadvantages to both that need to be considered before deciding what type of soil to grow turf in. [4] Native soils offer many positive qualities, such as high nutrient holding capacity, water holding capacity, and sure ...
Water-soluble soil conditioners offer the following benefits: [10] increase pore space in soils containing clay; increase water infiltration into soils containing clay; prevent soil crusting; stop erosion and water runoff; make friable soil that is easy to cultivate; make soil dry quicker after rain or irrigation, so that the soil can be worked ...
There are also many kinds of soil amendments, both organic and inorganic. [3] They promote soil quality in a variety of ways, such as sequestering toxins, balancing the pH of the soil, adding nutrients, and promoting the activity of organisms. [3] The current conditions of the soil will determine which type of amendment and how much to use. [3]
Soil sieve nests with dry soil aggregates after removal from a laboratory drying oven. Soil aggregate stability is a measure of the ability of soil aggregates—soil particles that bind together—to resist breaking apart when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage.
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse ...
A subsoiler or flat lifter is a tractor-mounted farm implement used for deep tillage, loosening and breaking up soil at depths below the levels worked by moldboard ploughs, disc harrows, or rototillers. Most such tools will break up and turn over surface soil to a depth of 15–20 cm (6–8 in), whereas a subsoiler will break up and loosen soil ...
Clay soils that lack organic matter and porosity benefit from the humic acid and soluble alginates found in seaweed. [ 1 ] [ 62 ] These compounds bond with metallic radicals which cause the clay particles to aggregate, thereby improving the texture, aeration, and retention of the soil by stimulating clay disaggregation.
