    The foliage is aromatic, especially when crushed, [10] with a fragrance described as sage-like, [13] a blend of sage and lavender, [14] or like turpentine. [15] The flowering season of S. yangii can be as long as June through October, [6] although populations in some parts of its range, such as China, may bloom in a much more restricted period. [8]

    Western US – One of the best spring forage sources for honeybees. Blooms 45–60 days and continuously produces nectar throughout the day. Can be seeded several times per year. Prefers 3 ft of topsoil. 180–1,500 pounds honey per acre, depending on soil quality and depth; 300–1000 pounds of pollen. [9] G, H Plantain: Plantago Major ...

  4. Soil test - Wikipedia

    en.wikipedia.org/wiki/Soil_test

    In agriculture, a soil test commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level. A soil test can determine fertility , or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive ...

    Although not a member of the genus of the common sage, it is closely related. It typically reaches 0.5–1.2 m (1 ft 8 in – 3 ft 11 in) tall, with square stems and gray-green leaves that yield a distinctive odor when crushed, but it is best known for its blue or violet blossoms arranged in showy, branched panicles .

    Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.

  7. Soil morphology - Wikipedia

    en.wikipedia.org/wiki/Soil_morphology

    Since the origin of agriculture, humans have understood that soils contain different properties which affect their ability to grow crops. [4] However, soil science did not become its own scientific discipline until the 19th century, and even then early soil scientists were broadly grouped as either "agro-chemists" or "agro-geologists" due to the enduring strong ties of soil to agriculture.

  8. Soil quality - Wikipedia

    en.wikipedia.org/wiki/Soil_quality

    Soil quality in agricultural terms is measured on a scale of soil value (Bodenwertzahl) in Germany. [6] Soil quality is primarily measured by chemical, physical, and biological indicators because soil function cannot easily be measured directly. [7] Each of these categories comprises several indicators that provide insight into overall soil ...

  9. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    The approach of other soil labs also entering the soil health field is to add into common chemical nutrient testing a biological set of factors not normally included in routine soil testing. The best example is adding biological soil respiration ("CO 2 -Burst") as a test procedure; this has already been adapted to modern commercial labs in the ...
