More substantial however is the leaching of the contents of phosphogypsum into the water table and consequently soil, exacerbated by the fact that PG is often transported as a slurry. [3] Accumulation of water inside of gypstacks can lead to weakening of the stack structure, a cause of several alarms in the United States. [6]
Some effects of agricultural lime on soil are: it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity [1] it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils. [2]
Other soil conditioner uses: Gypsum reduces aluminium and boron toxicity in acidic soils. It also improves soil structure, water absorption, and aeration. [40] Soil water potential monitoring: a gypsum block can be inserted into the soil, and its electrical resistance can be measured to derive soil moisture. [44]
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 ...
Gypsisols in the World Reference Base for Soil Resources (WRB) [1] are soils with substantial secondary accumulation of gypsum (CaSO 4.2H 2 O). They are found in the driest parts of the arid climate zone. In the USDA soil taxonomy they are classified as Gypsids (USDA Soil Taxonomy), in the Russian soil classification they are called Desert ...
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. [9]
A soap substitute is a natural or synthetic cleaning product used in place of soap or other detergents, typically to reduce environmental impact or health harms or provide other benefits. Traditionally, soap has been made from animal or plant derived fats and has been used by humans for cleaning purposes for several thousand years. [ 1 ]
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 ...
