Soil
microbial communities and their related characteristics are an important agent for soil fertility, productivity, and sustainability. Also, they are useful indicators of soil
quality and life index in agricultural systems. The
objectives of this study were the effect of nanozeolite and plant residues on soil microbial communities and their
characteristics and also, the assessment of incubation timing on soil microbial
properties. Soil microorganisms are
very important in the decomposition of plant residues. In this regard, the soil samples were treated by nanozeolite
(0, 10 and 30% Weight), Alfalfa and wheat straw (0 and 5% Weight). The treated soil samples were incubated in lab
condition for 90 days. The result of this study showed that Bacterial, Fungal,
and Actinomycete populations increased by the addition of 30% of nanozeolite and 5% of plant residues, especially alfalfa straw. Also, the
addition of nanozeolite and plant
residues treatments improved MBC, BR, and
SIR as microbial characteristics. These parameters increased after 30 days of
starting incubation, then decreased until the 75th day and finally
increased slightly on the 90th day. In fact, the addition of nanozeolite and plant residues into the soil
had positive effects on improvement of carbon pools and increasing carbon
sequestration in it. Applied nanozeolite
and plant residues in soil, improved carbon pools and increased carbon
sequestration in soil. Also the application of nanozeolite
and plant residues especially alfalfa straw had positive effects on improvement
of soil biological communities and characteristics.
