WebThis method requires the determination of CEC and percent exchangeable sodium (ESP). If soluble sodium is present, the exchangeable value is corrected by analysis of Na in a saturated extract.1 SAR, or sodium adsorption ratio is used to estimate or predict ESP by analyzing for Na, Ca, and Mg in a water saturated soil extract.2SAR is commonly … Web12K views, 365 likes, 19 loves, 187 comments, 9 shares, Facebook Watch Videos from National Assembly of Zambia: Parliamentary proceedings
How to Calculate Soil Cation Exchange Capacity OFFER
WebThe pH of your soil tells you how basic or acidic it is, which can influence the electrical conductivity results. pH is the measurement of ions as well, but specific ions. Positively charged hydrogen ions cause a substance to be more acidic, while negatively charged hydroxyl ions cause a substance to be more basic. Web6 sep. 2024 · Cation Exchange Capacity (CEC) is the soil’s ability to attract, retain and exchange positively-charged cations (cat-i-on). Like a magnet’s attraction to iron, the negatively-charged soil particles will attract and hold the … in many people\\u0027s mind
