In fertigated treatments, N and
K2O applications were split into 24 portions along six months of the crop cycle (Table 2), with 7 day interval between applications, and the first one was carried out 60 days after planting (DAP).
According to the XRF results, gold waste were largely comprised of SiO2 and Al2O3 and small amounts
K2O, Fe2O3, Na2O, CaO, MgO, SO3 and P2O5.
It is concluded that a dose of 100 kg
K2O ha was the most optimum for tomato plants at early growth stage.
According to [4] diagram, which is drawn according to Na2O and
K2O quantities in SiO2 and distinguishes the two magma alkaline and sub-alkaline quantities, all samples are categorized under sub-alkaline (fig.4).
Total emergence %age varied significantly (Table 2) for which T3 (150 kg
K2O ha-1) performed better with 97.102% of tuber emergence whereas, it was 91.264% in T0 (control).
A sample (AU46165) has very little Na2O (0.33) as compared to
K2O (1.88) which may be because high concentration of muscovite.
Concentrations of major elements and total REEs in all lithotypes Sample SiO2 A1203 Fe203 MgO CaO Na2O
K2O No.
The concentrate grades (Fe, V2O5, TiO2, SiO2, Al2O3, P, LOI, CaO,
K2O, MgO, Mn, and S) were then back calculated from these estimates.
For mulched crops with subsurface irrigation, broad-cast or band all P2O5, micronutrients and 20 to 25pc of N and
K2O in the bed area.
Abigail, from
K2O Dance, says: "We wanted to take our dancing to new levels and challenge ourselves to be creative and original - we think we have achieved this with a live duet in a swimming pool."
