CANLYNIADAU'R PRAWF PRIDD

Daeth canlyniadau'r prawf pridd o'r gwlau Cennin a'r Nionod drwy'r post rhai dyddiau yn ol:

LEEK BED

Analysis                   Result      Guideline     Interpretation           Comments

pH                               6.9              6.5              Normal                 Adequate level
Phosphorous                87               26                 High                   High level. No
                                                                                                      treatment necessary.
Potassium                    204            241             Slightly Low           100-150kg/ha K20
Magnesium                  165            100               Normal                 Adequate level

ONION BED

Analysis                   Result      Guideline     Interpretation           Comments

pH                               6.6              6.5              Normal                 Adequate level
Phosphorous               109               46                 High                   Possible interference
                                                                                                       on availability of  Fe,
                                                                                                       Cu, Zn
Potassium                    154            241             Slightly Low           100-150kg/ha K20.
Magnesium                  270            100               Normal                 Adequate level


Tydi'r canlyniadau ddim rhy ddrwg i ddweud y gwir, ond bydd rhaid ychwnegu rhywfaint o Potash i'r gwlau dros y gaeaf. Yr unig beth sy'n ymddangos braidd allan oi le ydy'r lefel uchel o Phosphorous yn y gwely nionod. Dwi ddim am golli cwsg dros y peth oherwydd dwin gobeithio creu gwely newydd i'r nionod yn y Polytunnel  fydd yn cael ei godi cyn y Dolig gobeithio.
