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 ...
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.
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.
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 ...
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 ...
