“…Organic farming is regarded as a farming system where soil fertility is regarded as the basis of production and therefore can optimize the quality of all the factors involved, especially the soil quality. Following the statement of Mustikaningrum (2018), the high content of organic matter in the soil will enhance the chemical, physical and biological properties of the soil and, in consequence, the quality of soil will also increase.…”

Rice (Oryza sativa L.) is a very important food crop because the result is used as a staple food for residents in Indonesia. Higher food fulfillment leads to the increase of rice production of the Mojogedang sub-district. Paddy fields that have high soil fertility will produce good rice productivity. Rice fields in Mojogedang Sub-district are managed with organic systems and conventional systems, the management of different fields of rice field certainly affects the level of fertility in the paddy fields so it is necessary to evaluate the soil fertility index. The survey area consists of 10 points with organic and conventional management systems. The parameters taken include chemical and biological properties of soil, including; pH, redox potential, C-organic, CEC, base saturation, P available, available K, N Total, C/N ratio, and total microbial. The data obtained by performed analysis of the main component principal component analysis (PCA) using statistical applications. Then after complete the calculation of The Soil Fertility Index (SFI) at each point and management system. The results of statistical analysis obtained soil Fertility Index on organic management systems have a class of 4 or very high and in conventional management systems have a class of 3 or High. The value of the index obtained is strongly influenced by the K indicator available where the indicator has a noticeable effect on the various management systems. Increased soil fertility index due to the use of manure that can improve plant nutrients and applied for long periods.

“…Farmers fertilize using inorganic fertilizers that leaving more residue, one of which is heavy metal. Cultivation should provide a pause to plant other crops in one year, for example rice-secondary crops-rice (Hindarwati et al, 2018;Supriyadi et al, 2019) The current problem is the assumption of farmers that by providing fertilizers with high doses can provide maximum results. Overfertilization using inorganic fertilizers can cause environmental damage and accumulation of heavy metals (Nungkat et al, 2015;Seshadri et al, 2015).…”

P fertilization can add Cd metal content to agricultural land because the raw material for making P fertilizer comes from phosphate rock which naturally contains Cd metal. Farmers assume that by providing fertilizers with high doses can provide maximum results. Community’s knowledge of heavy metals in the environment is still low. This study aims to examine the awareness of farmers in Sragen Regency Central Java to the potential of heavy metal pollution that occurs. This research was conducted from July to December 2017. The type of this research is quantitative descriptive research using a questionnaire with the number of respondents amounting to 10% of the number of farmers, namely 30 farmers. The results show that about 61.11% of the community doesn’t understand that the presence of heavy metals in the environment can cause many problems. About 60% of the community doesn’t understand that the inorganic fertilizers commonly used by them contain heavy metals (especially Cd metal). People unaware of heavy metal pollution due to over-fertilization is 65.01%. Although the community's knowledge and awareness of heavy metals are still low, the community awareness about environmentally friendly agriculture is high (61.33%). About 53.34% of the community doesn’t know that their behavior in using inorganic fertilizers in the long term will increase the accumulation of Cd metal in agricultural land and rice plant tissue. About 70% of the community doesn’t know that agricultural land that is used continuously to plant (without interspersed with non-paddy crops) will cause land degradation.

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. Assessment of soil quality is measured by physical, chemical and biological indicators, where each factor has a different effect. The chemical indicators are often used as the main indicators for determining soil quality, whereas every parameter has the opportunity to be the main indicator. 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.
