While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.

This text aims to introduce the results of the ecological footprint (EF) calculations in the system of organic agriculture (OA). The EF is an alternative indicator of the human activity impact on the environment. It is not calculated in monetary units but in hectares as an area needed for resourcing certain production or activity. OA is an agricultural system which respects natural cycles in ecosystems. It is based on old traditions and nowadays, with regard to environmental degradation, comes again forward. The text contains as well the results of some other researches studying mainly energy consumption in agriculture, which is further converted into the EF. The results, however, need to be compared very carefully, since the procedures of calculations as well as the organic farming rules in various countries or particular farms conditions and quality of input data of the mentioned studies may significantly differ. The authors cite them mainly because of illustrative reasons.

The principal goal of the organic farming system (OFS) is to develop enterprises that are sustainable and harmonious with the environment. Unfortunately, the OFS yields fewer products per land than the non-organic farming system in many agricultural products. The objective of our study was to assess the effects of digestate and biochar fertilizers on yield and fruit quality of processing tomato produced under the OFS. The experiment was carried out in Po Valley, during the 2017 and 2018 growing seasons. Liquid digestate (LD), LD + biochar (LD + BC) and pelleted digestate (PD) were evaluated and compared to biochar (BC) application and unfertilized control. The results showed that plants fertilized with LD + BC recorded the maximum marketable yield (72 t ha−1), followed by BC (67 t ha−1), PD (64 t ha−1) and LD (59 t ha−1); while the lowest production (47 t ha−1) was recorded in unfertilized plants. Over the two cropping seasons, LD + BC, BC, PD, and LD, increased fruit number per plant (+15%), fruit weight (+24%), Brix t ha−1 (+41%) and reduced Bostwick index (−16%), if compared to the untreated control. Considering the overall agronomic performances, digestate and biochar can be useful options for increasing yield and quality of processing tomato production in the OFS. Hence, these fertilizers can be assessed in future research both on other crops and farming systems.

The purpose of this PKM is to provide a solution of the problems facing counterparts cultivator of milkfish and Tilapia is Sipakamase Group in Gentung Village, Labbakkang Sub District, Pangkep District. The main problems faced by fish farmers in the district are the high use of inorganic fertilizer, the more of low quantity of produce, often the attack disease and decreacing quality of ponds. The target to be achieved is to give new technology innovation on the use of vermi-compost on the cultivation of milkfish and Tilapia by applying in minapadi system. This application is expected to used as a solution of the problems facing fish farmers. The method done begins with conducting observations on ponds, plan and design of minapadi system, application of vermicompost in the pond. The result of PKM are the rise of their knowledge and skill in organic farming system that capable to reduce the cost of the production and increase pond productivity.

The changes of the soil’s humus soil within the rural areas are investigated for the organic farming system. The most significant impact of organic agriculture on humus content over 55% was observed on soddy podzolic soils (V>75%), the lowest –7,5% on typical chernozem (V≈16%). Changes in the qualitative composition of humus for the introduction of various types of organic substrates are analyzed.
