“…The comprehensive application of organic and conventional fertilizer is an effective way to increase the productivity of rice plants (Liu et al, 2021). Soil fertility maintenance is a fundamental principle of sustainable farming (Sapinas & Abbott, 2020). This kind of maintenance can be carried out by calculating the Soil Fertility Index (SFI).…”

Rice farming in Madiun Regency implements three different management systems, that is organic, semi-organic, and conventional. The different implementation of these rice field management systems impacts soil fertility index and rice productivity. This purpose of this research was to know the effect of rice field management systems on soil fertility index and rice productivity in the Madiun Regency. The research uses an explorative descriptive qualitative method with a survey approach. Soil samples were taken using a random sampling method and 3 types of soil management systems (conventional, semi-organic and organic), and rice production samples were taken using an estimation method. The research results show that the soil fertility index ranges from 0.78 to 0.82, which is high. The highest soil fertility index is in the semi-organic management system and the lowest is in the organic management. The management system of semi-organic gave a response to the highest rice production of 6.89 tons/ha. Management system of semi-organic is a better management for increasing and maintaining soil fertility and crop production than conventional or organic. Farming activities results show that organic management systems increase the highest income, increasing 115.58% and 53.30% in semi-organic compared to conventional. The rice field management system has the effect of increasing the worm population density with the highest in the organic system, namely 4.19 individuals m-2. The Pontoscolex worm type dominates the three management systems. There is a correlation between organic matter content and earthworms.

“…The best way to achieve this goal is to use efficiency-improving measures in conventional agriculture while reducing negative externalities, while also introducing organic farming [Gamage et al 2023]. The literature indicates that organic farming systems may result in a lower level of production than the conventionally-managed systems [Sapinas, Abbott 2020]. In Western European countries, however, the demand for agricultural products from organic farms is increasing [Mazurek-Kusiak et al 2021].…”

This study addresses the issue of assessing the functioning of farms in areas with diverse natural farming conditions by evaluating them using the latest version of the Agricultural Production Area Valorization (APAV) index. Analyses were performed on three types of farms: fully organic farms, organic farms with co-existing conventional production, and conventional-production farms. To achieve the research objective, 259 communes were selected depending on the level of their APAV. Assessments were made of their production potential, production organization, production and economic results in communes with average APAVs below, equal to, and higher than the national average (66.6 points) based on data from farms continuously keeping accounts for the Polish farm accountancy data network (FADN) in between 2019–2021. The Shannon-Wiener index (S-W index) was used to measure the degree of diversity of crop species in the farms’ sown crops, and determine what proportion of those were structure-forming plants. This research demonstrates that in order for interest in organic production to develop under current conditions, there must be sufficient financial support for agricultural producers, especially in areas with more difficult farming conditions.

Aims: One-time high rates of compost were applied at 15, 30, and 45 Mg ha-1 to improve soil organic matter (SOM) and fertility in dryland organic winter wheat-fallow rotations. Cover crop mixtures (oats and Austrian winter peas) were planted in fallow phases annually to suppress weeds and reduce repetitive tillage used for weed control because the latter breaks down SOM. Study Design: The experiment was laid-out in a split-plot design with four replications. Fertilizer (compost rates, inorganic fertilizer and no amendment control) and cover crops served as main and sub-plot factors respectively. Place and Duration of Study: The experiment was conducted at the Sustainable Agriculture Research and Extension Center, University of Wyoming, from September 2015 to August 2018. Methodology: Soil samples, weed biomass, wheat yield and protein quality data were collected and analyzed over three years. Results: Results indicated that 45 Mg ha-1 compost increased (P=.05) soil total carbon (TC) and nitrogen (TN) concentrations up to 25 and 19% respectively, in the last two years. Wheat yield was not affected (p>0.05) by compost or cover crops in any growing season but 45 Mg ha-1 compost increased (P=.05) protein quality by 2-9% in the first growing season. Cover crops suppressed weeds while growing in the first growing season but had varying effects on weeds in wheat phases that followed them in rotation. It was noted that soil electrical conductivity levels affected by 45 Mg ha-1 compost was 5 times lower than wheat thresholds; and soil moisture loss by cover crops did not affect wheat yield. Conclusion: 45 Mg ha-1 compost improves soil fertility and SOM in the short term. However, significant reflection of soil changes in wheat yield may take longer time. Further research is needed to effectively integrate cover crops as a weed control measure in dryland organic wheat-fallow rotations.
