Sentence examples for extractable potassium from inspiring English sources
For medium-textured soils, significant differences between regions were observed for most indicators except subsurface compaction (PR45) and extractable potassium.
However, the same was not verified with the values of the exchangeable bases, extractable potassium and phosphorus and exchangeable acidity that differ from the observed ones before the fire.
Here a national scale XRPD dataset of Scottish soils is used in combination with the rule-based regression algorithm 'Cubist' for prediction of eight soil properties (total carbon and nitrogen, cation exchange capacity, pH, aqua regia extractable potassium, and the sand, silt and clay size fractions), and interpretation of soil property mineralogy relationships.
Extractable potassium (Kext), calcium (Caext) and sodium (Naext) were determined using a flame photometer (Elico™ CL378) after extraction with neutral 1 N ammonium acetate solution.
The results showed that MSS applied in the experiment significantly improved soil properties of the mined land i.e. increase in organic matter content, available phosphorus, extractable potassium and magnesium, DTPA extractable copper, and zinc.
They were characterized by the local laboratories (Table 4) for their dry matter content, total P content, water extractable P, total potassium (K) and N content, and their ammonium N content.
Extractable calcium, magnesium, potassium, sodium, and sulfur were determined following Suarez (1996).
We analyzed soil samples for extractable calcium (Ca), magnesium (Mg), potassium (K), cation exchange capacity (CEC), pH, bulk density, A-horizon depth, total carbon (C), and nitrogen (N).
As the Xyl/Ara ratio has been applied as a negative indicator for the Ara substitution degree of xylans in Miscanthus[ 17], we calculated the Xyl/Ara values of both potassium hydroxide (KOH -extractable and non-KOH -extractablehemicelluloses.
Total Inorganic N (TIN) was measured with two replicate 3 g field-moist sub-samples from each plot that were analyzed for 2 M potassium chloride (KCl) extractable nitrate + nitrite (NO3− + NO2−) and ammonium (NH4+) [24] on a Lachat QuikChem 8000 (Lachat Instruments, Loveland, CO, USA).
