“…In the case of nitrogen, a higher content of sand fraction has negative influence, mainly to the labile components, because the probability of their binding to the mineral portion of the soil is lower, resulting in lower their physical stabilization. The less stabilized organic matter is, the faster is nitrogen released (Triberti et al, 2008). The result will be also a lower content of labile nitrogen.…”

In this study, the changes in soil organic matter (SOM) and the possibilities of their monitoring in a shorter period of time by means of carbon parameters were followed. The experiment includes four ecosystems (forest, meadow, urban, and agro-ecosystem) on Haplic Chernozem (Močenok, Horná Kráľová, Trnava) and Haplic Luvisol (Ludanice, Veľké Zálužie, Lovce) of different localities. The objectives of this study were assessment of the differences in the stability of soil organic matter in different ecosystems and in soil types using labile forms of carbon and nitrogen, and also with dependence on particle size distribution. The highest contents of total organic carbon (TOC) and labile carbon (C L ) were in a forest ecosystem, but in case of other ecosystems, the differences were determined only in the contents of C L . After forest ecosystem, the highest content of C L was in agro-ecosystem > meadow ecosystem > urban ecosystem. Based on parameter of lability of carbon (L C ), the most labile carbon can be evaluated also in the forest ecosystem (0.209) > agroecosystem (0.178) > meadow ecosystem (0.119) and urban ecosystem (0.116). In the case of nitrogen, the differences were observed between the soils. Higher contents of NT and N L were recorded in Haplic Chernozen than in Haplic Luvisol. Contents of TOC (P < 0.05; r = -0.480), C NL (P < 0.05; r = -0.480), and N L (P < 0.01; r = -0.545) were in a negative correlation with the content of sand fraction. The values of studied parameters in meadow and urban ecosystems were relatively balanced, because in both cases, the vegetation cover were grass, pointing to a significant influence of vegetation on the parameters of SOM. ekosystémoch a pôdnych typoch s využitím labilných foriem uhlíka a dusíka a v závislosti od pôdnej textúry. Najvyššie obsahy TOC aj C L boli v lesnom ekosystéme, ale medzi ostatnými ekosystémami boli stanovené rozdiely len v obsahoch C L . Po lesnom ekosystéme bol najvyšší obsah C L v agroekosystéme > lúčnom ekosystéme > urbánnom ekosystéme. Na základe parametra lability uhlíka (L C ) môžeme tiež hodnotiť za najlabilnejší uhlík v lesnom ekosystéme (0,209) > agro-ekosystéme (0,178) > lúčnom ekosystéme (0,119) a urbánnom ekosystéme (0,116). V prípade dusíka boli zaznamenané rozdiely medzi pôdnymi typmi. Vyššie obsahy NT aj N L boli zaznamenané v černozemi ako v hnedozemi. Obsahy TOC (P < 0.05; r = -0.480), C NL (P < 0.05; r = -0.483) a N L (P < 0.01; r = -0.545) boli v negatívnej závislosti od obsahu frakcie piesku. Hodnoty sledovaných parametrov v lúčnom a urbánnom ekosystéme boli pomerne vyrovnané, pretože v obidvoch prípadoch boli vegetačným krytom trávy, čo poukazuje na výrazný vplyv vegetácie na parametre SOM.

“…In Haplic Luvisol, the stability of organic substances is lower, therefore, the nitrogen will release faster. Subsequently, the nitrogen can be adsorbed by the roots, or quickly lost through the processes of denitrification, volatilization (Triberti et al, 2008), and nitrification (Stevenson, 1986).…”

“…A significant part of the organic carbon is associated with the stable fraction of organic matter and it has been turned over thousands of times over the years (Semenov et al 2013). The content of N t decreased in the following order: FYM > G+NPK3 > G+NPK1 > G. The nitrogen soil content was strictly related to C org and varied more in response to organic material supply than to mineral N rates or to the kind of N fertiliser (Triberti et al 2008), however, in our case C org contents did not correlate with N t in all treatments of fertilisation (FYM: r = 0.492, P > 0.05, n = 8; G+NPK3: r = 0.032, P > 0.05, n = 8; G+NPK1: r = 0.279, P > 0.05, n = 8). C org and N t contents varied by the addition of fertilisation, but without statistical significance (Table 2).…”

“…The use of organic manure caused the fastest build up of the N in the soil, followed by crop residues (in our case grass biomass). These Different letters between lines (a, b) indicate that treatment means are significantly different at P ≤ 0.05 according to LSD multiple-range test G -control; FYM -farmyard manure; G+NPK3 -doses of NPK fertilisers in 3 rd intensity for vineyards; G+NPK1 -doses of NPK fertilisers in 1 st intensity for vineyards; C org -soil organic carbon content; N t -total nitrogen content; P -available phosphorus; K -available potassium effects can be explained by the fact that the lower the stabilisation of organic matter (crop residues < manure), the higher the nitrogen release (Triberti et al 2008). Opposite situations have been recorded (Table 3).…”

The effect of fertilisation on C and N, P, K nutrients distribution in the Rendzic Leptosol in locality Nitra-Dražovce was studied. We evaluated the following treatments of fertilisation: (1) G (non-fertilised), (2) FYM (farmyard manure -dose 40 t/ha), (3) G+NPK3 (grass + 3 rd intensity of fertilisation for vineyards), and (4) G+NPK1 (grass + 1 st intensity of fertilisation for vineyards). The soil samples were taken in spring during the years 2008-2015. Obtained results showed that the content of organic carbon (C org ) decreased in the following order: G+NPK1 > FYM > G > G+NPK3 and content of total nitrogen (N t ) decreased in the following order: FYM > G+NPK3 > G+NPK1 > G. The application of NPK in the 1 st intensity of fertilisation for vineyards and added FYM build up a C org at an average rate of 370 and 229 mg/kg/year, respectively. On the other hand, contents of N t due to fertilisation declined in FYM, G+NPK3 and G+NPK1 at an average rate of 53, 22 and 20 mg/kg/year, respectively. Available P and K contents were also increased after the fertilisation of FYM and NPK. Added fertilisers (G+NPK3) significantly build up a P at an average rate of 10.2 mg/kg/year.

“…All forms of N fixation contribute to N pollution of the biosphere, a planetary boundary which is being dangerously exceeded (Rockström et al 2009). It seems that systems using organic fertilisers are less N efficient and result in increased N pollution than synthetic fertiliser which can more precisely target plant needs (Triberti et al 2008).

Implications of oil depletion for biodiversity

Since the 1950s the growth of the human population and per capita consumption has accelerated, raising concerns about the limits to growth due to resource constraints. The oil supply has been of particular concern, with production predicted to peak in the first decades of the 21 st century. This is a problem because modern society is highly dependent on the supply of petrochemicals for its energy, including modern industrialised agriculture. One of the key inputs to agriculture that is dependent on petrochemicals is mineral nitrogen (N), which has increased agricultural yields since 1960s. Constraints to the supply of petrochemicals increase the risk that agriculture will become less productive, requiring more land to maintain food production and threatening biodiversity.This thesis investigates the relationship between the oil supply, food security, global deforestation and biodiversity loss, assessing the worst-and best-case scenarios for agriculture's footprint without petrochemicals. It also examines the spatial footprint of alternatives to mineral N globally.I used a constraint to the oil supply during the 2007-8 global financial crisis to investigate the dynamics between the oil supply, agriculture's spatial footprint and the impact on biodiversity. Ifound that the rate of forest loss increased 29% during this period, and that as a result an additional area of forest the size of Italy was lost. This loss tended to occur in areas of remnant forest with higher biodiversity. I investigated the likely drivers of forest conversion and found that agricultural extensification and the production of renewable energy were probable contributors, but land grabbing by foreign countries to secure food supplies was not. I also found examples of successful policy implementation in Amazonian Brazil and in Australia which had resisted these changes.To investigate the potential threat from agricultural expansion associated with constraints to petrochemical supply, I looked at worst-and best-case scenarios. For the worst-case, I estimated the area that would be required for crop production without petrochemical-based nitrogen fertiliser using N-use efficiency data and current yields. I then spatially modelled cropland expansion globally and the impact this would have on biodiversity and food security. Without mineral N there was insufficient cropland to meet global food needs with many regions experiencing food insecurity. Cropland would expand onto the remaining fertile land leaving largely poor quality habitat for biodiversity.In the best-case scenario, I identified the N source with the smallest footprint by comparing the most land-efficient renewable energy sources to power the Haber-Bosch process and organic sources of N. Solar power was significantly more land efficient than the alternatives. The worstcase option of using no mineral N fertiliser would require about 2000 times the land area and would have about 81,000 times the impact on biodiversity. Although solar energy is the most land-efficient way of poweri...
