Plot Design

A field experiment was carried out in the years 2012–2018 in Poland in a split-plot design. The aim of the study was to determine the long-term effect of legumes as forecrops on the productivity of rotation with nitrogen fertilization. The rotation included: legumes + spring barley (SB), winter rape (WR), winter wheat (WW) and winter wheat. The study was conducted as a two-factorial field experiment with four replications. The present study showed that legumes as forecrops increased the yield of all after-harvest crops in rotation. Yielding of these crops also depended on nitrogen fertilization and position in the rotation. After comparison of the influence of nitrogen fertilization on yield of cereals, it was observed that the effect of this factor was greater for WW cultivated in the fourth year of rotation than for WW cultivated in the third year of rotation. In relation with control, each dose of nitrogen fertilization caused a significant increase of WR and cereals yield, but the dose of 180 kg N/ha did not increase yield significantly in comparison to the dose of 120 kg N/ha. There was also negative agronomic N-efficiency observed between doses of 120–180 kg N/ha, which means that it is not necessary to use 180 kg N/ha, especially if there are legumes in crop rotation.

The long-term effect of N and P fertilisation on the grain yield, yield components and quality parameters of winter wheat was studied for different sites in the National Long-term Fertilisation Trials in Hungary. This network of small-plot fertilisation experiments has been maintained since 1967 in nine different agro-ecological regions of the country. Increasing P and N doses had a considerable effect on the grain yield, yield components and quality parameters of winter wheat according to the results evaluated in the first 20-year average of the experiments. However, these effects differed depending on the agro-ecological conditions of the sites. Yield increases could be detected at lower fertiliser doses, and improvement in quality parameters at higher rates.

Long Term Effect

The present work aims to implement a ‘healthy checkout’ in a real retailing environment in order to demonstrate that this kind of intervention can be a win-win strategy for both shoppers and retailers in a long-term perspective. A field experiment has been conducted in five stores belonging to a leading Italian Retailer in the north of Italy, where all the unhealthy products have been removed from the checkouts. Both sales analysis and shoppers attitudes towards the intervention have been studied. Sales data have been analyzed for the ‘healthy checkout stores’ vs ‘traditional checkout stores’, and customers have been interviewed at the end of the shopping trip five months after the implementation. Our findings show that developing a healthy checkout can have a positive impact on sales, retailer’s reputation in terms of perceived CSR, and loyalty to the store. The present work provides some interesting results about the long-term effect of an in-store marketing strategy that aims to promote health among customers.

Abstract. Retardation of soil organic carbon (SOC) decay after nitrogen addition to litter or soil has been suggested in several recent studies and has been attributed to a retardation in lignin decay. With our study we tested the long-term effect of mineral nitrogen fertilization on the decay of the SOC component lignin in arable soil. To achieve this, we tracked 13C-labeled lignin and SOC in an arable soil that is part of a 36-year field experiment with two mineral nitrogen fertilization levels. We could show that nitrogen fertilization neither retarded nor enhanced the decay of old SOC or lignin over a period of 36 years, proposing that decay of lignin was less sensitive to nitrogen fertilization than previously suggested. However, for fresh biomass there were indications that lignin decay might have been enhanced by nitrogen fertilization, whereas decay of SOC was unaffected. A retardation of SOC decay due to nitrogen addition, as found in other experiments, can therefore only be explained by effects on lignin decay, if lignin was actually measured.
