  2. Soil thermal properties - Wikipedia

    en.wikipedia.org/wiki/Soil_thermal_properties

    It is hard to say something general about the soil thermal properties at a certain location because these are in a constant state of flux from diurnal and seasonal variations. Apart from the basic soil composition, which is constant at one location, soil thermal properties are strongly influenced by the soil volumetric water content, volume ...

    That’s because the pH neutralizes as the grounds decompose, so you won’t have to worry that you’re going to throw off your garden’s soil pH off when using compost with coffee grounds.

  4. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  5. Soil moisture - Wikipedia

    en.wikipedia.org/wiki/Soil_moisture

    The amount of water already in the soil; Soil temperature. Warm soils take in water faster while frozen soils such as permafrost may not be able to absorb depending on the type of freezing. [37] Water infiltration rates range from 0.25 cm per hour for high clay soils to 2.5 cm per hour for sand and well stabilized and aggregated soil structures ...

  6. Hardpan - Wikipedia

    en.wikipedia.org/wiki/Hardpan

    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 ...

  7. Soil water (retention) - Wikipedia

    en.wikipedia.org/wiki/Soil_water_(retention)

    Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. [2]

  8. No-till farming - Wikipedia

    en.wikipedia.org/wiki/No-till_farming

    Another possible benefit is that because of the higher water content, instead of leaving a field fallow it can make economic sense to plant another crop instead. [25] A problem with no-till farming is that the soil warms and dries more slowly in spring, which may delay planting. Harvest can thus occur later than in a conventionally tilled field.

  9. Agricultural soil science - Wikipedia

    en.wikipedia.org/wiki/Agricultural_soil_science

    Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. Emphasis continues to grow on the importance of soil sustainability.
