This study provides appropriate solutions regarding good
soil quality, especially the influence of biological indicators on the process
of increasing biological activity to improve the quality of paddy fields and
increase rice production. Soil quality provides physical, chemical, and
biological requirements for soul productivity, food quality and health,
environmental safety of the animal and human plants. Increased rice needs in an
extensive use of paddy fields in the Jatipurno, Wonogiri. Managing rice fields
can reduce soil quality. Proper management can improve soil quality, Jatipurno
has management such as organic, semi-organic and inorganic paddy field
management which have a real effect on soil quality. Physical, chemical, and
biological indicators are used to assess the quality of soil; the effects of
each aspect vary. While each measure has the potential to be the primary
indicator, chemical indicators are frequently utilized as the primary
indicators for assessing soil quality. So, biological indicators can play indicators.
The main indicators are obtained from the correlation test (p-values ≤ 0,05 -
< 0,01) and Principal Component Analysis with high value, eigenvalues > 1
have the potential to be used as Minimum Data Sets. The result is biological
can be able to use as the Minimum Data Set such as microbial carbon biomass,
respiration, and total bacterial colonies. The Soil Quality Index (SQI) of
various paddy management practices shows very low to low soil quality values.
The management of organic rice systems shows better Soil Quality Index with a
score of 0,20 compared to other management. The practice of organic rice
management shows that it can improve soil quality. The quality of paddy soil in
Mangunharjo Village managed organically has better soil quality compared to
semi-organic and inorganic management with soil quality index values
respectively 0.20, 0.17 and 0.15.
