“…Soil acidification could also result from the activity of nitrifying microorganisms whose growth is stimulated by the application of organic wastes, and high sulfate concentrations (Bohacz and Korniłowicz-Kowalska 2005). Foereid (2017) found that the pH level of soil did not affect the availability of P from the tested organic products. The findings of other authors are contradictory due to a variety of factors such as soil type, dose and type of animal wastes, and weather conditions (Valenzuela et al 2000, Svoboda et al 2010, Brod et al 2012, Bøen and Haraldsen 2013.…”

A field experiment was conducted in 2011 – 2013 in Poland. The objective of this study was to determine the effect of increasing doses of meat and bone meal (MBM) on the mineral nitrogen (Nmin) and available phosphorus (P) content of soil and the soil pH. Changes in the content of NH4+-N, NO3--N and available P in soil were affected by MBM dose, experiment duration, weather conditions and crop species. Soil amended with MBM was more abundant in mineral N and available P. The lowest concentration of NO3--N and the highest concentration of NH4+-N were noted in the first year of the study, because the nitrification process requires a longer time. MBM had no influence on the accumulation of Nmin in soil, whereas the concentration of available P increased significantly throughout the experiment. The soil pH decreased with increasing MBM doses. After the application of the highest MBM doses soil pH classification was changed from neutral to slightly acidic.

“…The combined addition of CM and 15% BM could significantly promote the decomposition of organic carbon during CB composting. This increase could be due to the low content of soluble phosphate in BM [40] and the generous microbial communities and enzymes in CM [13].…”

In China, chestnut burrs (CB) are produced at a rate of a million tons per year as the major byproduct of chestnut orchards. It is necessary to utilize the chestnut forest green waste and convert it into a valuable seedling media for the sustainable cultivation of chestnut seedlings. In this study, we composted CB with two waste products of cattle farming, namely cow manure (CM) and bovine bone (BM). We also evaluated the potential of CB compost application in chestnut forest sustainability. Results indicated that the best combination was the addition of 15% BM and 55% CM. This combination significantly improved the composting environment by increasing pH, enhancing phosphorus concentration and mineral elements such as Ca, Na, Mg and Zn, and shortened the composting period to 38 days. This combination also resulted in the highest content of citric acid-P (109.20 times than the control treatment) and the lowest content of NH 4 + -N (0.28 times than control treatment) indicating a better N and P structure of the final compost product. This combination achieved a greater degradation rate of CB cellulose (61.45%), hemicellulose (37.87%), and a more significant degradation of outer epidermis structure. When CB compost was used as a growing media, a significant decrease in photosynthesis stress of chestnut seedlings was observed, which was mainly manifested as a decrease in photochemical quenching (qP) and an increase of the maximum efficiency of PSII photochemistry under dark-adaption (Fv/Fm). Addition of 10% CB compost (in volume basis) is suggested, which resulted in the tallest chestnut seedlings (59.83 cm) with a stem diameter of 0.91 cm after six months of growth. In summary, this research provides an environmentally friendly strategy for chestnut orchard sustainability: rapid composting of CB, then immediate application as a high-quality substrate for chestnut seedlings.Agronomy 2020, 10, 288 2 of 18 step for chestnut production. The popularization of burr removal equipment has resulted in the need for intensive management of CB. Due to CB recalcitrant biodegradability and knotty spicular structure, incineration is still the main method of dealing with CB waste [3,4]. Since CB, as FGW, is rich in organic matter and minerals, it is desirable to convert it into a high value byproduct such as compost.Composting is a popular and clean method to dispose of FGW [5]. Mature FGW compost has high porosity and high organic carbon content and can be utilized as a high-quality soil amendment [6]. Shrestha et al. [7] reported that the application of compost increased soil organic carbon content, reduced CO 2 and N 2 O emissions, and increased CH 4 uptake. Chehab et al. [8] indicated that the olive FGW compost amendment resulted in an increased performance in mature olive trees and in a maximum yield of photosystem II (Fv/Fm). Composting recycles organic matter, nitrogen, phosphorous, and mineral elements in the FGW when growing seedlings [9]. In a recent study, Shalizi et al. [10] increased the biomass of Eucalyptus bentham...

To develop a circular economy, nutrients from waste streams need to be recovered and brought back to agricultural production as much as possible. Liquid waste streams pose a specific problem because high water content makes transport expensive. Treatment of wastewater and diluted waste streams to recover nutrients are briefly discussed, and two options that are not much used are discussed: sorption to increase the fraction of nutrients found in the solid phase and nitrification of liquid to reduce nitrogen losses. Then, availability of nutrients to plants and environmental effects are discussed. It is concluded that there is little information on how treatment options affect how bioavailable the nutrients are and that this should be taken into account when treatment option is chosen.
