The Effects of Applications Humic Acids on Macronutrient, Micronutrient, Heavy Metal and Soil Properties
Abstract
This
study was conducted on the YYU campus area as a field survey, according to the
randomized block experimental design carried out in three replicated. The
yellow and orange marigold species with humic acids (HA0;0 kg HA da-1,
HA1;10 kg HA da-1, HA2;20 kg HA da-1, HA3;40 kg HA da-1)
were used. At the end of the experiment, the soil samples taken from the field
of study were analyzed organic matter, soil reactions, total salt content, lime
content, nitrogen, phosphorus, potassium, calcium, magnesium, natrium, iron,
manganese, zinc, copper, cadmium, nickel and lead contents. The increased humic
acid applications have influenced pH (P<0.01), lime (P<0.01), organic
matter (P<0.05) with phosphorus (P<0.01), iron (P<0.05), zinc
(P<0.05) and nickel (P<0.01) contents. The effect variety (V) has been
determined on the available of soil iron (P<0.01), zinc (P<0.01), cadmium
(P<0.01), nickel (P<0.01), and lead (P<0.01) contents. The interaction
of only affected the nickel (P<0.01) and zinc (P<0.01) contents. As a
result, humic acid applications have an important and positive effect on many
properties of soil.
