what part of the agricultural product was to do deposit as text ?
Answers
Explanation:
Compost is organic material that can be added to soil to help plants grow. Food scraps and yard waste together currently make up more than 30 percent of what we throw away, and could be composted instead.

Salts and Trace Elements
The salt content (salinity) of soils and the frequently associated drainage problems are pervasive in agriculture. Salinity affects germination as well as seedling and vegetative growth. It also reduces crop yields. Waterlogging causes poor aeration in the root zone, with effects ranging from reduced growth to death of plants. Some constituents of salinity, such as sodium, may have a deleterious impact on the physical condition of the soil, impairing crop production.
About 19 million ha (47 million acres), or 10 percent of U.S. cropland, is irrigated (Postel, 1990). About 5.2 million ha (14 million acres) of this irrigated land is currently affected by salt. Salinity problems are not restricted to irrigated areas and arid climates. Halvorson (1990) estimates that nearly 1 million ha (2.5 million acres) of productive agricultural dryland in the western United States has been salinized through saline seeps. Salinity problems also occur in humid regions through, for example, seawater intrusion into low-lying coastal farmlands.
Soil salinization is a worldwide problem. According to Szabolcs (1989), about 1 billion ha (25 billion acres) of the world's soils are affected by salt. Saline and sodic (sodium-containing) soils cover about 10 percent of the world's arable lands and exist in 100 countries. Szabolcs (1989) reports that, worldwide, some 10 million ha (25 million acres) of irrigated land is abandoned annually because of salinization, sodification, and waterlogging.
Worldwide, in the arid-to-semiarid regions where irrigation is practiced, soil salinization and the frequently accompanying waterlogging
