Positive Effect

Cylindrical coaxial heaters are increasingly used in agricultural production. However, their widespread use is restrained by the fact that it is still necessary to supplement the calculation methodology, which would make it possible to take into account its geometric dimensions, dielectric and magnetic permeability, surface effect and proximity effect, uneven distribution of electric and magnetic fields along the heater, and a number of other factors when choosing the parameters of the heater. Such a task is relevant in the design of electric heaters for the production needs of dairy farms, taking into account what the methodology presented below has been developed. This technique gave a positive effect in relation to the development of an experimental electric pasteurizer.

Positive Effect

Dutch nutrient policy aims at reducing leaching of agricultural nutrients by internalizing the negative externalities associated with inefficient nutrient use. This is done by taxation of nitrogen and phosphate surpluses that exceed a hectare-based threshold of maximum-allowed surpluses. One management strategy farmers may use to reduce the nutrient surpluses on their farms is to improve the nutrient efficiency of the agricultural production process. This study employs Data Envelopment Analysis (DEA) to calculate nitrogen and phosphate efficiencies and an overall nutrient efficiency measure for a 3-year panel of 114 Dutch dairy farms. Subsequent analyses show the impact of both farm intensity and nutrient efficiency on the nitrogen and phosphate surpluses. It appears that farm intensity has a positive effect on efficiency, but efficiency and intensity exert opposite influences on nutrient surpluses. This is especially the case for nitrogen. The magnitude of a possible reduction of nitrogen surpluses through a strategy of efficiency improvement is therefore limited by the intensity of the farming system, unless the technology with which nutrients are used by the farming system can be further improved or input/output ratios will be altered.

In this paper, we explore the link between energy and agricultural production in Bolivia, Peru, and Colombia. The economic literature and policy reports, discussed here, indicate that access to energy (electricity) has a positive effect on agricultural production. To test this hypothesis, we look at the agricultural census and national survey to estimate the effect of energy use on the value of production using the Propensity Score Matching (PSM) technique. We found that, in the three countries, access to energy increases the value of agricultural production.

The paper presents the assessment of the degree of sustainability of agricultural production using the ecological, economic and social indicators included in the RISE model in selected four dairy farms. The research was conducted in the Lubelskie and Podlaskie provinces. The analysis shows that none of the analyzed farms can be considered sustainable under the adopted methodology because they did not have positive values for all 12 indicators characterizing the different aspects of sustainability. Farms in the Lubelskie province and one farm in the Podlaskie province was engaged in intensive agricultural production, using high fertilization fertilizers, which caused problems with the fertilizer economy, and the “N and P” emission potential was high. At the same time, these farms showed little respect for biodiversity but achieved good economic results. Farms in Lubelskie voivodeship, in spite of problems have better managed the fertilizer economy than farms in Podlaskie voivodeship. In the selected farms, the biggest problem was the achievement of a positive biodiversity value, which resulted from the use of intensive production technologies.

The main aims of the article are: 1) defining the changes of energy costs in farms focused on milk production and further divided according to their economic size in Poland and other selected EU countries between 2005 and 2016; 2) analysis of electricity and fuel (diesel) costs in Polish dairy farms between 2005 and 2016; 3) characterisation and evaluation of the current Polish subsidy system for fuel used for agricultural production purposes. The subject of research was dairy farms from selected EU countries participating in the FADN system. The implementation of the third objective boiled down to a critical analysis of the amendment to the Act introduced in Poland: “On the refund of excise duty included in the price of diesel used for agricultural production”. The research shows that in farms focused on cattle breeding and milk production in seven analysed EU countries, the average share of “energy” costs in the structure of total costs fluctuated (in 2005, 2010, 2016) from 2.72% in the largest Danish farms in 2016 to 13.08% in the smallest Polish farms in 2005. Regardless of the country, an increase in the economic size of farms focused on milk production, resulted in energy cost savings in relation to 100 kg of milk produced. The analysis of legal solutions implemented in Poland shows that dairy farms are able to potentially obtain higher subsidies for diesel oil used for agricultural production. This is very debatable from an economic point of view. INTRODUC

In the land of Nema, fields show low agricultural potential due to high human and climatic pressure. To increase their agricultural production, the populations have opted either for the use of chemical fertilizer or for the supply of manure through the Agriculture-Livestock integration. This paper focuses on evaluating the effect of on-farm use of manure on groundnut pod and groundnut production, and nutrient balance at the field level. 20 square plots of 2m each were used per field on the monitored farms. The hay and pod samples were taken therein, weighed, and dried in an oven at 60° C to a constant weight. This work was carried out for both fertilized fields and unfertilized fields (controls). In these same farms, samples of manure produced were collected and analyzed. The production of peanut and groundnut pods in the fertilized fields and in the control fields shows an overall positive effect of the manure on the yields in the land of the Néma. Taking into account the figures of the average deficits, the nitrogen, phosphorus, and potassium balance is deficient in ground-level groundnut peanut fields. This is due to the low manure doses per hectare and its low nutrient content.

Abstract Stabilizing agricultural production is fundamental to food security. At the national level, increasing the effective diversity of cultivated crops has been found to increase temporal production stability, i.e., the year-to-year stability of total caloric production of all crops combined. Here, we specifically investigated these effects at the regional level for the European Union and tested the effect of crop diversity in relation to agricultural inputs, soil properties, climate instability, and time on caloric, protein, and fat stability, as we hypothesized that the effect of diversity is context dependent. We further investigated these relationships for specific countries. We found that greater crop diversity was consistently associated with an increase in production stability, particularly in regions with large areas equipped for irrigation and low soil type diversity. For instance, in Spain and Italy, crop diversity showed the strongest positive effect among all predictors, while on the European level, the stabilizing effect of nitrogen use was substantially higher. In Germany, the crop diversity-stability relationship was weak, suggesting that crops react similarly to climatic, economic, and political factors or are grown in the same periods. With this study, we substantiate previous findings that crop diversity stabilizes agricultural caloric production and extend these with regard to protein and fat. The results elucidate the key drivers that enhance production stability for different European countries and regions, which is of key importance for a comparably productive agricultural region like Europe.

ABSTRACT With the expansion of agricultural production, native Cerrado areas are replaced with other forms of land use. Thus, the objective of this study was to evaluate changes in the physical fractionation of organic carbon (C) in areas under different forms of land use in the Cerrado. The treatments, with five repetitions, corresponded to the following forms of use: area under conventional tillage, area under pasture plantation, area under eucalyptus plantation and area under native Cerrado vegetation, at the depths of 0-5, 5-10, 10-15 and 15-20 cm in the municipality of Luis Eduardo Magalhães, BA, Brazil. The highest C contents and stocks were found in the eucalyptus area, which were equal to those of the area under native Cerrado vegetation, while particulate C stocks were higher in the area under pasture at the depth up to 10 cm, not differing from the area under native Cerrado. Pasture and eucalyptus had positive effect on C management index, regardless of depth.

: Nanotechnology is one of the most important modern sciences that has integrated all sectors of science. Nanotechnology has been applied in the agricultural sector in the last ten years in pursuit of increasing agricultural production and ensuring food security. Plant biotechnology is an essential science that is concerned with plant production. The use of nanotechnology in plant biotechnology under controlled conditions has facilitated the understanding of important internal mechanisms of the plant biological system. The application of nanoparticles (NPs) in plant biotechnology has demonstrated an interesting impact on in vitro plant growth and development. This includes the positive effect of the NPs on micropropagation, callus induction, somatic embryogenesis, cell suspension culture, and plant disinfection. In addition, other biotechnology processes, including the genetic transformation of plants, plant conservation, and secondary metabolite production have improved by the use of NPs. Furthermore, nanotechnology is used to improve plant tolerance to different stress conditions that limit plant production. In this review article, we attempt to consolidate the achievements of nanotechnology and plant biotechnology and discuss advances in the applications of nanotechnology in plant biotechnology. It has been concluded that more research is needed to understand the mechanism of nanoparticle delivery and translocation in plants in order to avoid any future hazardous effects of nanomaterials. This will be key to the achievement of magnificent progress in plant nanobiotechnology.

In the article the combined influence of surface effect, proximity effect, ring effect and slot effect on active and self-inductive resistances of the inductor, placed inside the hollow cylindrical workpiece, are investigated. It had been shown that the combined influence of these effects forms a distribution of current over cross-section of the inductor tube. That current determines the values of active and self-inductive resistances of the inductor. There had been presented dependencies of relative coefficients of active and self-inductive resistances of the inductor and relative geometrical parameters of the system "inductor – hollow finite-sized workpiece", the gap between the inductor and the workpiece, and specific resistance of heated nonmagnetic workpiece in presence and absence of internal magnetic core.
