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.

Long term productivity and conservation of soils is critical for sustaining agricultural ecosystems. The specific objective of the work reported was to determine the effects of long term application of organic and mineral fertilizers on soil enzyme activity as an index of soil biology and biochemistry. Three key soil enzymes involved in intracellular metabolism of microorganisms and two soil enzymes involved in phosphorus metabolism were selected. Actual and potential dehydrogenase, catalase, acid and alkaline phosphatase activities were determined in the 0-20 cm layer of an eroded soil submitted to a complex fertilization experiment. Results showed that addition of mineral fertilizers to organic (green manure and farmyard manure) fertilizers led to a significant increase in each activity because of increased plant biomass production which upon incorporation stimulates soil biological activity. The enzymatic indicators of soil quality calculated from the values of enzymatic activities depending on the kind of fertilizers showed that by the determination of enzymatic activities valuable information can be obtained regarding fertility status of soils. A weak positive correlation between enzymatic indicators of soil quality and maize yield was established. The yield data demonstrate the superiority of farmyard manure which provided greater stability in crop production. Substantial improvement in soil biological activity due to application of organic fertilizers with mineral fertilizers contribute in maintaining the productivity and soil health.

Tuber Protein

Potato protein is a valuable source of essential plant-derived amino acids, the composition of which is similar to that of chicken egg protein considering the amino acid reference. Many factors used in potato cultivation can modify its composition. The use of bio-fertilizers in potato growing offers a possibility of a better use of minerals from soil and organic sources and reducing the need for mineral fertilizers by activating minerals present in soil. The effect can be to improve not only the potato tuber yield but also the nutritional value. The aim of this study has been to determine the hanges in the content of crude protein and the composition of amino acids in potato tubers, depending on the application of the bio-fertilizer (UGmax), organic fertilizers (pea as a catch crop, straw, and farmyard manure (FYM)) as well as mineral fertilization (100% and 50% of the reference rate). The application of bio-fertilizer significantly increased the content of essential and non-essential amino acids in potato tuber protein. With the half-decreased mineral fertilization rate, bio-fertilizer most effectively increased the content of tyrosine, methionine, asparagine in potato tuber protein in the treatments with FYM or with a catch crop as well as without organic fertilization.

This experiment was designed to determine the effect of spent mushroom substrate, farmyard manure, and mineral fertilization with nitrogen, phosphorus, and potassium on the yield and quality of raw material obtained from two cultivars (“Słoneczko” and “De Dolj”) of common thyme. Unfertilized plots with thyme crops were included as the control treatment. Different row spacings (30 cm and 40 cm) represented the second experimental factor. The highest total yield of thyme raw material was found in the treatment with mineral NPK fertilization, but also in the treatments where spent mushroom substrate (SMS) and mineral NPK fertilization were applied at a ratio of 50:50%. Fertilization with SMS alone (100%) yielded smaller production effects, but they were higher than in the case of fertilization with manure. The high suitability of spent mushroom substrate applied alone or supplemented with mineral fertilization at different rates in spring was confirmed by the best quality parameters and antioxidant properties of the raw material. The use of a wider row spacing (40 cm) resulted in a higher yield of thyme raw material than in the case of a narrower one (30 cm). The narrower row spacing significantly positively affected some of the analyzed quality parameters of the harvested raw material, such as: essential oil content, polyphenol content, and antioxidant activity. The thyme cultivar “Słoneczko” proved to be absolutely more beneficial in terms of yield quantity and quality than the foreign cultivar “De Dolj”.

Actual and potential dehydrogenase and catalase and phosphatase activities were determined in the 0–20–, 20–40– and 40–60–cm layers of a brown luvic soil submitted to a complex tillage and crop rotation experiment. The soil under maize or wheat was more enzyme-active in the 6– than in the 2–crop rotation. In the 2–crop rotation, higher enzymatic activities were registered under wheat than under maize. In the 6–crop rotation, the enzymatic indicators of soil quality decreased, depending on the nature of crops and kind of fertilisers (mineral NP or farmyard manure), in the following order: farmyard-manured maize > minerally fertilised (m.f.) soybean > m.f. wheat > m.f. maize (plot 4) > m.f. maize (plot 1) > m.f. clover.

Npk Fertilization

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.

AbstractThe excessive use of mineral fertilizers affects soil quality, gives rise to environmental problems and consumes energy. In contrast, organic amendment may improve soil quality at the same time as providing nutrients to plant. The aim of the work was to study the effects on crop yield and soil microbial activity of the successive addition of mineral fertilizers and fresh pig slurry before each successive crop compared with one sole application of different pig slurry composts (solid fraction of a pig slurry (CSFPS) and fresh pig slurry plus wood shavings (1:1 v/v; CPS+WS) before planting the first crop. Compost-treated soils exhibited higher organic carbon content than inorganically fertilized soils, throughout the experimental period. However, N content in the former soils was lower than in the latter after the second crop. Nevertheless, yields obtained with repeated additions of fresh pig slurry or with a sole application of pig slurry composts were similar to those obtained with repeated mineral fertilization. After the horticultural crops, organically treated soils generally showed higher values of both microbial biomass and metabolic microbial activity (measured as basal respiration and dehydrogenase activity) than the soil receiving mineral fertilization. Subsequently, the organically amended soils showed higher protease, phosphatase and β-glucosidase activities than the inorganically fertilized soil and similar levels of urease activity. From this study it can be concluded that both fresh and composted pig slurry can be used as an alternative for mineral fertilizer in growing horticultural crops and maintaining soil quality.
