Measuring Soil Fertility with NPK Tests

Description

Soil fertility can be measured by testing the macronutrients nitrogen, phosphorus, and potassium. These three nutrients are major parts of soil fertilizer, and their levels help show how well soil can support plant growth.

The experiment uses chemical extraction to pull each nutrient out of the s...

Transcript

Bodemvoedselanalyses kunnen worden uitgevoerd om drie belangrijke macronutriënten, stikstof, fosfor en kalium, uit de bodem te extraheren en deze te combineren met kleurreagentia om hun concentratie te bepalen.

Stikstof, fosfor en kalium zijn belangrijke componenten van bodembemesting. Het kennen van hun concentratie in de bodem kan milieu...
