“…The final content of nitrate and ammonium in soils was relatively low at the end of the crop harvest [11]. The obtained values for NO 3 -N content in the soil were similar to the results obtained by other authors upon application of pig slurry [35,50], sludge waste materials subjected to different stabilization treatments [45], and mineral fertilization treatments with ENTEC ® [35], with values generally lower than 10 mg·kg −1 and no differences between mineral and organic treatments. Nitrate values below 20 mg·kg −1 would be classified as 'low', according to Zhu et al [52].…”

“…Residual NO 3 − -N contents were higher in the fertilized subplots (ranging from 20% to 77%) than in the control subplot. The highest soil nitrate enrichment did not correspond to the highest N application rates (T1 and T5 for mineral and organic fertilization, respectively), in contrast to other studies in which the maximum leaching nitrate losses were generated when the highest amounts of N were applied [49,50]. This will be discussed later on.…”

“…Nitrate values below 20 mg·kg −1 would be classified as 'low', according to Zhu et al [52]. The values for the NH 4 + -N content would, in turn, be expected to be lower than 10 mg·kg −1 and lower than the nitrate content [10,45,50,53]. However, the transformation process of ammonium into nitrate is strongly correlated with the pH [54][55][56] and, in soils with pH 8.0-as is the case in this experiment-a strong reduction in the nitrification process is known to occur [56].…”

Nitrate vulnerable zones (NVZs) are areas considered to be at high risk of water pollution due to an excess of nitrates and, according to European regulations, codes of good agricultural practice are to be implemented by farmers, such as reducing doses of the applied fertilizers, or the use of fertilizers that minimize nitrate leaching. In this work, the influence of organic fertilization with dried pig manure (DPM) as compared to mineral fertilization with ammonium sulfate nitrate with 3,4-dimethylpyrazole phosphate nitrification inhibitor was studied in a barley crop planted in a NVZ in Fompedraza (Valladolid, Spain). Organic and mineral fertilizers were applied at different rates (85, 133 and 170 kg N·ha −1 ·year −1 vs. 90 and 108 kg N·ha −1 ·year −1 , respectively) over a three-year period, in a randomized complete block design with six treatments and four blocks. DPM-based fertilization resulted in a 65% increase in crop yield as compared to the control soil, reaching 1800 kg·ha −1 for an application rate of 85 kg N·ha −1 ·year −1 . Higher DPM rates were found to increase the electrical conductivity and assimilable phosphorus, potassium, magnesium and organic matter contents, but did not lead to yield enhancements. Final nitrate and ammonium concentrations were lower than 10 mg·kg −1 and 20 mg·kg −1 , respectively, and no increase in soil salinity or heavy metal pollution was observed. DPM fertilization should be supplemented with small doses of inorganic fertilizers to obtain crop yields similar to those attained with mineral fertilization.

Two field experiments were conducted in Galbana village, North Sinai Governorate during two winter seasons 2011/2012 and 2012/ 2013, to evaluate the environmental effect of mineral nitrogen fertilizer rate, compost and bio-fertilizer on some soil properties and sugar beet productivity under newly reclaimed saline soil. The seeds of sugar beet (Beta vulgaris) variety Loil were inoculated with Rhizobium radiobacter strain (salt tolerant PGPR). Results indicated that the soil pH was not significant as affected by bio-fertilizer or compost alone or in combination with different rates of mineral nitrogen fertilizer. The soil salinity decreased with increasing rate of mineral nitrogen combined with bio-fertilizer or compost. The relative increases of soil available N content in soil due to mineral nitrogen fertilizer; compost and biofertilizer after sugar beet cultivation, followed the descending order: bio-fertilizer> compost > mineral N as compared with initial soil for available N content. The relative increases in both P and K followed the descending order: compost > bio-fertilizer > mineral N fertilizer as compared with soil initial contents of P and K. The available micronutrients ie Fe, Mn, and Zn in soil were not significantly affected by the different fertilization treatments in both the first and second seasons. Also, available Fe was not significantly affected with rate of the used fertilizers whereas the effects of different rates on the available contents of both Mn and Zn were significant in the second season, however in the first one such rates were of significant effect of Zn only. The interactions among bio-fertilizer, compost and mineral nitrogen rates were of significant effects on Mn content in soil in both seasons whereas such an effect was significant on Fe in both seasons and Mn in the first one. The highest mean values of fresh and dry root yield, sugar yield, total soluble solids (TSS), purity and sucrose were achieved due to treating soil with bio-fertilizer together with the mineral nitrogen fertilizer. The highest values of N (1.14 %) concentration in root was observed at soil treated with compost plus 100 kg mineral N fertilizer, while the maximum values of P and K concentration (0.28 % for P and 1.29 % for K) was observed as affected by bio-fertilizer plus 100 kg mineral N, respectively. On the other hand, the effect of all treatments tested on Fe, Mn and Zn concentration in root of sugar beet was non significant. As a conclusion, bio-fertilizer and compost application in sugar beet could increase characteristics of sugar beet root and reduced consumption of mineral nitrogen fertilizer and successfully reduced the hazard effect of soil salinity condition.

-Composting provides an excellent way to manage the huge volume of organic waste and convert it into a useful soil amendment. The effectiveness of composted organic waste can be further improved by enriching and blending it with nutrients and biologically active substances. The resulting value-added composts can be used at substantially low rates such as a few hundred kg per ha compared with conventional use of organic wastes in tons per ha. This approach could have practical significance in reducing the use of chemical fertilizer for sustainable agriculture and the environment. L-tryptophan is a precursor of the growth hormone indole acetic acid and is known to stimulate plant growth at extremely low concentrations. Here, we studied the effect of composted fruit and vegetable wastes, enriched with N at 133 g kg −1 compost, with or without L-tryptophan at 10 mg kg −1 compost, on soil and maize crops. The enriched compost was applied at 300 kg ha −1 to a sandy clay loam soil either by mixing with the top 15-cm soil layer in pots or as a band placement along the maize plants grown in the field. The compost was applied alone and in combination with 40 or 80 kg ha −1 urea N and compared with a treatment containing 160 kg N ha −1 , a full dose of N fertilizer alone, while P and K fertilizers were applied in all the treatments. Our results show that application of the enriched compost to soil increased aggregate stability by up to 24.8% and water retention by up to 43.1% compared with untreated control. A gradual increase in the concentration of indole acetic acid in compost, ranging from 1.02 to 3.34 mg kg −1 , was observed when compost was treated with its precursor L-tryptophan. The results of pot and field experiments revealed that compost enriched with N and L-tryptophan in the presence of 80 kg N fertilizer significantly increased cob and grain yields, by up to 19.8 and 21.4%, respectively, compared with a full dose of N fertilizer. These findings suggest that enrichment of composted organic wastes with N and L-tryptophan can change them into a value-added organic product that could be used as a soil amendment at rates as low as 300 kg ha −1 to increase crop production on a sustainable basis.auxins / biologically active substances / maize / nitrogen / organic fertilizer / organic waste / recycling soil aggregate
