Do you know the nutrient level of the soil in your garden? Do you know how much fertilizer to add next season? Soil testing will answer both questions.
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology.GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
The square foot gardening method recommends using an open-bottom raised bed, 4 by 4 feet (1.2 m × 1.2 m) square. The square beds are then divided into a grid of sixteen one-foot squares. Each square is planted with a different crop, and based on the plant's mature size either 1, 4, 9 or 16 plants are placed per square.
The Palmer Drought Index is based on a supply-and-demand model of soil moisture. Supply is comparatively straightforward to calculate, but demand is more complicated as it depends on many factors, not just temperature and the amount of moisture in the soil but also hard-to-calibrate factors including evapotranspiration and recharge rates.
A historic surface soil moisture change in the Horn of Africa from August 2020 - December 2022. Soil moisture is the water content of the soil. It can be expressed in terms of volume or weight. Soil moisture measurement can be based on in situ probes (e.g., capacitance probes, neutron probes) or remote sensing methods. [1] [2]
A horticulture student taking a soil sample in a garden near Lawrenceville, Georgia. A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order ...
