Taimedele omastatava P sisalduse määramine mullast Mehlich 3 meetodil

Taimedele omastatava fosfori (P) määramine mullast on oluline saagikuse ja keskkonnahoiu seisukohalt. Üha enam kasutatav M3 meetod ei pruugi alati usaldusväärselt peegeldada taimedele omastatava P tegelikku sisaldust. Käesoleva töö eesmärk oli uurida, kuivõrd kajastab Mehlich 3 meetodil määratud P sisaldus tegelikult taimedele kättesaadavat P ning ...

Extraction of Soil Nutrients Using Mehlich-3 Reagent for Acid-Mineral Soils of Florida

EDIS, 2014
Soil testing is a multistep process starting with the collection of a sample that adequately represents the area or field to be tested. Due to wide-ranging soil conditions across Florida and the United States, multiple soil test methods exist. During the 1970s, Florida along with several other southeastern US states adopted Mehlich-1 (M1) as the ...

Iron interference in Mo determination in Mehlich-1 and Mehlich-3 soil extracts

, 2009
Among the essential plant nutrients, molybdenum (Mo) has the lowest concentration in soils. A routine method for the determination of soil Mo availability is not yet established. Soil analysis methods have been tested but not one has been set to be used in a routine basis in Brazilian laboratories.
