Other claims from this paper (13)
- Intervention effect Chemical pools of soil Zn under incubation with graded Zn fertilizer levels showed significant variation in almost all locations.
- Intervention effect The highest added Zn (10 kg Zn ha-1) always produced greater Zn release than lower doses.
- Observation Release of water soluble plus exchangeable, organically bound and crystalline bound Zn was higher at 15 days after incubation and gradually declined by 30 days.
- Observation Manganese oxide bound and amorphous sesquioxide bound Zn showed a prolonged release up to 30 DAI.
- Observation Residual Zn and total Zn showed a prolonged release up to 30 DAI.
- Observation The order of preponderance of Zn fractions was WS and EX < OM < AFe-OX < CFe-OX < MN-OX < RES, the same for all locations.
- Observation More than 95 % of total soil Zn occurred in the inactive, mineral-bound residual form.
- Observation Only a small fraction of soil Zn occurred in the WS and EX, OM, AFe-OX and CFe-OX fractions.
- Intervention effect Maize in the pot culture experiment responded well to Zn fertilizer application.
- Intervention effect At the very low Zn location, 7.50 kg Zn ha-1 gave a higher maize dry matter production of 76.4 g plant-1.
- Intervention effect At the very low Zn location, 7.50 kg Zn ha-1 gave a higher maize Zn uptake of 3.34 mg plant-1.
- Association Soil Zn fractions were in dynamic equilibrium and were influenced by pH, EC, CEC, organic carbon and DTPA-Zn.
- Intervention effect Zn release and maize response to Zn fertilizer were always higher in very low Zn soil, followed by low, medium and high Zn soils.
