2. List of vineyard soil types - Wikipedia

   en.wikipedia.org/wiki/List_of_vineyard_soil_types

   This soil warms quickly and retains heat well. The soil's high level of acidity works to minimize the acid levels in the grapes which works well with acidic grapes like Gamay. It is the main soil type of the Brand region of Alsace. [2] Gravel – Loose siliceous pebble soil that has good drainage but poor fertility. Vines planted in this type ...

3. Circumneutral - Wikipedia

   en.wikipedia.org/wiki/Circumneutral

   Circumneutral is a descriptor for soils which have a pH that is close to neutral. Circumneutral soils have a pH between 6.5 and 7.5. [1] A soil’s pH affects whether minerals dissolve in the soil and how quickly they dissolve. This causes circumneutral soils to have unique chemical qualities. [2]

4. Glossary of viticulture terms - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_viticulture_terms

   Vineyard soil type made up of sedimentary rock containing calcium carbonate which has desirable drainage and water-retention for grape growing. Limestone soils tend to produce grapes with high potential acidity levels due to inhibiting the vines from up-taking potassium ions that neutralize acids in the wine grapes.

5. Soil pH - Wikipedia

   en.wikipedia.org/wiki/Soil_pH

   Global variation in soil pH. Red = acidic soil. Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics.

6. Vigna subterranea - Wikipedia

   en.wikipedia.org/wiki/Vigna_subterranea

   Optimal soil depth is between 50 and 100 cm, [11] with a light soil texture. [11] Soil fertility should be low [11] and soil pH is best suited between 5 and 6.5 [11] and should not be lower than 4.3 [11] or higher than 7. [11] Bambara groundnut is tolerant to salinity, but high sodium chloride concentration in the soil will result in yield losses.

7. Soil acidification - Wikipedia

   en.wikipedia.org/wiki/Soil_acidification

   Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid , such as nitric acid , sulfuric acid , or carbonic acid .

   WASHINGTON (Reuters) -Donald Trump has tapped Keith Kellogg, a retired lieutenant general who presented him with a plan to end the war in Ukraine, to serve as a special envoy for the conflict, the ...

9. Soil biodiversity - Wikipedia

   en.wikipedia.org/wiki/Soil_biodiversity

   Soil structure is essential to soil health and fertility; soil structure decline has a direct effect on soil and surface food chain and biodiversity as a consequence. Continued crop cultivation eventually results in significant changes within the soil, such as its nutrient status, pH balance, organic matter content, and physical characteristics ...
