Effect of crop rotation and fertilization on quality of tomato cv. New Yorker was studied in field conditions in a long term, static experiment, conducted in Skierniewice since 1922. Tomatoes in crop rotation were cultivated on same field every third year. whereas these in monoculture were continuously cultivated on same field for 9 consecutive years (1980-1988). The fertilization treatments included: l) farmyard manure in rate of 40 t per hectare, annually, 2) mineral fertilization of 150 kg N. 100 kg P<sub>2</sub>O<sub>5</sub> and 200 kg K<sub>2</sub>O per hectare, 3) farmyard manure plus mineral fertilization as in treatments 1 and 2 and, 4) mineral fertilization as in treatment 2 plus microelements in form of a multimineral, commercial fertilizer (Polichelat LS 7). Crop rotation had no significant influence on the content of soluble solids, colour and weight of fruits. However, tomato fruits from plants cultivated in rotation, as compared to those from monoculture, contained more organic acids and pectins, less nitrates, had lower pH and greater firmness. The effect of fertilization was similar in rotated and non-rotated cultivation. At combined manure and mineral NPK fertilization, tomato fruits showed higher content of soluble solids, organic acids and pectins than these from the other fertilization treatments. Fruits of plants fertilized with farmyard manure only had higher content of vitamin C and lower one of nitrates, soluble solids and organic acids and also lower firmness as compared these from other fertilization in trial.

In order to improve environmental sustainability of tomato cultivation and the quality of the harvested fruits, we tested (a) the digestate from anaerobic fermentation of buffalo slurries as partial replacing of NP fertilizers and (b) the biodegradable mulching to improve the nutrients and water availability for crop and to control weeds. In 2017–2018, a private farm of Campania region hosted a trial with four treatments deriving from the combination of two experimental factors: (1) fertilization strategy (standard farm NPK fertilization vs. digestate combined with reduced rates of NP fertilizers); (2) soil mulching (biodegradable mulching vs. no mulching). We measured fresh and dry aboveground biomass (fruits and stem + leaves), yields, fruits quality. Results pointed out: (1) combination of digestate with reduced rates of NP fertilizers did not decrease yields compared to complete mineral fertilization; (2) yields were improved in 2017 by synergic effects of soil mulching and combination of digestate and reduced rates of NP fertilizers; (3) in both the years, digestate combined with reduced rates of NP fertilizers and soil mulching determined the significant improving of fruits quality parameters interesting the processing industry, namely, fruit color, and firmness, total soluble solids, titratable acidity while antioxidant activity, contents of ascorbic acid, polyphenols, flavonoids, and lycopene showed responses variable with year or cultivar.

In this paper we provide new data about the soil enzyme activity as a biological process, which is an indicator for impacts of factorial combinations of lime and fertilizers applications. Five plots divided into fifteen subplots were sampled for determination of the enzymatic indicators of soil quality, based on the actual and potential dehydrogenase and catalase activities. The research revealed that limed soil samples, in comparison with unlimed ones, resulted in significantly higher soil enzymatic activities (p[0.05) in the upper (0-20 cm), while in the deeper (20-40 cm) layer, only catalase activity was significantly higher (at least at p[0.02). Mineral fertilization, in comparison with its farmyard manuring, led to an insignificant increase in each of the three enzymatic activities determined, excepting catalase activity which was significantly higher (0.05]p]0.02) in the 0-20 cm layer. Based on the absolute values of the enzymatic activities, the enzymatic indicators of soil quality (EISQ) were calculated. The mineral NPK-fertilization and low dose of lime in the 0-20 cm layer, and mineral NP-fertilization and low dose of lime in the 20-40 cm layer proved to be the best variants of fertilization. The enzymatic indicators of soil quality in these variants reached the highest values: EISQ=0.821 and EISQ=0.889, respectively, indicating the presence of high enzymatic activities. It should be emphasized that a balanced application of lime, mineral fertilizers and farmyard manure leads to the formation of favorable conditions for the development of microorganisms, growth of plants and for an intense and lasting enzymatic activity.

This study evaluated how organic manures and mineral fertilizers affect winter wheat grain and straw yields and grain quality properties. The analysed period of the long-term fertilizer experiment was established in Čáslav, Czech Republic, in 1955 and covers the seasons 2011–2014. The fertilizer treatments were: control; farmyard manure (FYM); FYM + P; FYM + K; FYM + PK; FYM + N<sub>1</sub>; FYM + N<sub>2</sub>; FYM + N<sub>1</sub>PK; FYM + N<sub>2</sub>PK and FYM + N<sub>3</sub>PK. The highest grain yields were recorded in the FYM + P and FYM + N<sub>3</sub>PK treatments (8.9 t/ha). The highest straw yields were recorded in the FYM + N<sub>3</sub>PK treatment (6.52 t/ha). The lowest yields were provided in the unfertilized control and FYM treatments. Qualitative parameters were evaluated in the control, FYM and FYM + N<sub>3</sub>PK treatments between the years 2011 and 2013. The best quality of wheat grain was provided by the FYM + N<sub>3</sub>PK treatment. Combination of the farmyard manure with NPK is the best way to achieve high grain yields with good quality and leads to sustainable food production.

Increasing doses of farmyard manure (FYM) or equivalent mineral NPK fertilizers and their combinations were analysed in a crop rotation with potato, maize and winter wheat with special regard to their long-term influence on soil fertility. The yield-increasing capacity of FYM doses was only 82%, as compared to the equivalent amount of mineral NPK. Fairly high N release (50.9 kg ha −1 ) could be observed on the unfertilized plots. Great differences in N utilization were recorded, depending on the form and dose of fertilizers. The average N utilization from FYM was only 29.3%, while that of the equivalent fertilizer application was 49.8%. The lowest soil reactions were observed without fertilization and at the highest NPK doses. Negative N balances generally resulted in low soil organic matter content. FYM and equivalent NPK fertilizers had a similar influence on the ammonium lactate (AL)-extractable K 2 O content of the soil, while an increase in the AL-P 2 O 5 content could be observed in the case of mineral fertilization.

Soils were sampled from the plots with four variants of fertilisation: Nil – without fertilisation, NPK – mineral fertilisation, FYM – farmyard manure, FYM + NPK – farmyard manure with mineral fertilisation, and two variants of crop rotation: field IV – classical 9-year crop rotation, field B – 2-year rotation of alternative growing. Determination of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity was conducted during the period 1999–2004. The urease activity was positively affected by manure fertilisation (FYM) and by the combination of FYM + NPK. The statistically significantly highest counts of <I>Azotobacter</I> spp. and the highest nitrogenase activity were determined on field B in variants FYM and FYM + NPK. The results show that there was a higher amount of accessible nitrogen present on field IV than on field B. This might explain the lower counts of <I>Azotobacter</I> spp. and therefore the lower nitrogenase activity. According to our results, activity of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity are very closely connected with N inputs.

AbstractThis study evaluated the effects of organic agriculture manuring systems on carrot (Daucus carota) root morphology and sugar and polyacetylene content. Carrots were harvested three times per season 2006–2007 in a long-term field experiment at Skilleby research farm, Sweden. The effects of pelleted chicken manure, fresh farmyard manure and composted farmyard manure (COM) were compared against control plots left unmanured since the field experiment started in 1991. The carrots were analyzed for root size, root shape, amount of soluble sugars and amount of falcarinol-type polyacetylenes. Differences between manuring systems were found to be smaller than the variation between harvest years and harvest occasions, probably due to the grass-clover ley included in the crop rotation system. On an average for the six harvests, manuring with COM increased root length by 6% compared with fertilizing with pelleted chicken manure. Carrots fertilized with pelleted chicken manure also had 6–7% lower total soluble sugar content than carrots manured with 50 t ha−1 of composted or fresh manure. The falcarinol to total falcarinol-type polyacetylenes ratio was 15.4% in carrots manured with 50 t ha−1 of composted or fresh manure and 14.7% in carrots fertilized with pelleted chicken manure. Seasonal fluctuations in falcarinol-type polyacetylenes were more pronounced in carrots manured with fresh or composted manure than in carrots fertilized with pelleted chicken manure. The results suggest that manuring organic carrots with compost may be the most beneficial strategy, at least in systems where fertilizer is applied only once per crop rotation, whether directly to the carrot crop or in the preceding crop.

The stabilisation of 14C-labelled farmyard manure was investigated under different cropping systems (crop rotation, monoculture, and bare fallow) in a long-term field experiment established in 1967. Solid-state 13C-NMR of bulk soils yielded a gradient of increasing aromatic properties in the order: straw manure–crop rotation < straw manure–monoculture < straw and farmyard manure–bare fallow. The opposite trend was observed for O-alkyl groups. The farmyard manure–bare fallow treatment was used to investigate changes of humic acids (HAs) with time. The FT-IR bands of aromatics, carbonyl groups, and a band of methyls and benzene rings increased over the 36 years of the experiment, whereas 2 amide bands and a band of sulfone and/or ester groups decreased. Fluorescence spectroscopy verified the increase in aromatic properties with age. Consequently, during soil organic matter stabilisation, HAs showed increasing properties of carbonyl and aromatic groups, whereas amidic groups decreased. The dynamic character of HAs, as shown by 14C, was also reflected by distinct spectroscopic changes over the period of investigation.
