Complimentary Effect Of Humic Acid And poultry Manure On Soil Chemical Properties And The Growth Of Maize
ABSTRACT
An experiment was
conducted to determine the effect of Poultry Manure and Humic Acid on the
growth of maize and on soil chemical properties. There were three levels each
of Poultry Manure and Humic Acid (9 treatment combinations) applied to 4kg
soils. The treatment were replicated three times to give a total of 27 pots.
Data were collected on plant height, leaf length, number of leaves, leaf width
and soils were analysed for some selected chemical properties. From the results
obtained, there were indications that treatment combination were effective in
'improving soil properties and growth of maize. lOml of HA gave the highest
mean value on plant height, leaf length, width and stem girth while the control
had the lowest mean values. The combiiation of lOtons of PM with lOmi of HA
gave the highest mean value for all the parameters throughout the sampling
period. The results showed the treatment combinations were effective in
improving soil properties. The combination of lOton of PM with lOml of HA gave
the best effect on soil organic carbon, exchange Mg, Zn, Ca, K, available
nitrogen, Fe and Mn. Generally, The trend in improvement in the plant by the
rate of application of PM + HA was 0/0, 5/0, 10/10, 5/5, 5/10, 10/5 and
lO/lOtons of PM and HA respectively
