“…The values of ANRNH4-N for solid fraction (5-47%) obtained in our experiment were close to the range (12-63%) reported for solid cattle manures by Muñoz et al (2004), indicating a general lower short-term ammonium availability for crops from solid manures compared to liquid slurries. As opposed to 2011, in 2012, ANR and ANRNH4-N were very similar across the organic treatments, with an average recovery of applied total N and NH4-N of 24% and 52%, respectively.…”

An understanding of crop availability of livestock slurry nitrogen (N) is necessary to maximise crop N use efficiency and to minimise environmental losses. Results from field and laboratory incubation experiments suggest that first-year crop availability of slurry N comes mainly from its ammonium fraction because net mineralisation of organic N is often negligible in the short term. A two-year field experiment during 2011 and 2012 in northern Italy was undertaken with several aims: to estimate the N fertiliser value of raw dairy cow slurry, digested dairy cow slurry, and the liquid and solid fractions of the digested slurry, and to verify if applied ammonium recovery was similar both among slurries and between slurries and inorganic N fertiliser (ammonium sulphate).Different fertilisers were applied before silage maize cultivation followed by an unfertilised Italian ryegrass crop. The results showed that ammonium recovery was significantly higher in mineral-fertilised (75%) versus slurry-fertilised (30%) treatments, except in digested slurry (65%). This indicates that ammonium applied with organic materials is less efficient than when applied with mineral fertiliser. For the digested slurry and its liquid fraction, most of the applied ammonium was available to the maize during its application year (55%) due to a low carbon (C)/organic N ratio. The apparent N recovery of the raw slurry and digested slurry solid fraction increased substantially between the first (-1.4%) and second (20%) years, as these materials had high C/organic N ratios; they likely immobilised N for several months post application, producing residual effects during the Italian ryegrass and next maize crops. IntroductionRaw and anaerobically digested livestock slurries can be valuable fertilisers because they supply nutrients and organic matter to the soil.Anaerobic digestion of organic biomasses has seen considerable growth in Europe (Eurobserv'er, 2013) and in northern Italy (Fabbri et al., 2013) over the last decade.Many biogas plants co-digest livestock and biomasses to increase methane production, and in northern Italy, energy crops are often dedicated for co-digestion (Fabbri et al., 2013). To facilitate the use of digested slurries as fertilisers, liquid and solid fractions are separated to ease their transport (Möller and Müller, 2012).A deep understanding of applied slurry nitrogen (N) turnover in soil, and identification of practices to reduce N losses are required to maximise crop N use efficiency and to minimise environmental losses. Nutrient management plans (NMPs) maximise crop N use efficiency through calculation of the slurry amount needed for optimal crop production, and determination of application dates that match crop nutrient requirements according to soil type, local climate, and crop characteristics (Grignani et al., 2003). The slurry N fertiliser value is normally accounted for in a NMP by apparent nitrogen recovery (ANR), an expression of the fraction of applied total N that on average can be taken up by the cro...

Animal manure contains significant amounts of nitrogen (N) and phosphorus (P) that can be utilized as fertilizer. However, manure application rates are generally set to meet crop N demand, which results in excess P application which increases the risk of P loss into bodies of water. We examined the application method of manure compost based on crop P demand on the dry matter yield of silage corn (Zea mays L. var. indentata), on nutrient uptake and on soil P accumulation in an upland Andosol with a high P-fixing capacity. Cattle and poultry manure composts (CMC and PMC) with different P solubility were applied to meet the crop's N requirements (N-based application) or P requirements (P-based application) in 3 consecutive years. Supplemental N was applied using polyolefin-coated urea in the P-based treatments. The dry matter yields and nutrient uptakes of silage corn in the P-based CMC and PMC application systems were similar to those in the corresponding N-based systems. The average relative efficiency of N in CMC (33%) was close to the predicted value (30%) during the study. On the other hand, the relative efficiency of N in PMC (42%) was higher than the predicted value (28%). The average relative efficiency of P from CMC and PMC was 109% and 50%, respectively. These were higher than the predicted values based on the available P proportion (the sum of water-and sodium bicarbonate-soluble P) for CMC (78%) and PMC (34%), indicating that the available P fraction in the manure composts was more effective than that in P fertilizer for corn growth or that the other P fractions were also effective for corn. P-based manure compost application lowered the soil P accumulation to between 41 and 43% of the value in the N-based accumulation (versus a value of between 31 and 40% of that value for soil Truog-P). Compared to N-based manure compost application, P-based manure compost application with supplemental N fertilizer produced similar dry matter yields of corn and suppressed soil P accumulation in the upland Andosol field.

Due to increasingly strict control of wastewater treatment, the production of sewage sludge is surging and the problem of its disposal is therefore also growing. Recycling this waste as a fertilizer is an economically and environmentally attractive option. Determining the availability of macro-and micronutrients in these sludges is important if such wastes are to provide sufficient nutrients to crops while causing minimal environmental damage. A greenhouse study with two kenaf cultivars ('Everglades 41' and 'Tainung 2') was designed to evaluate the effects of sewage sludge processing mode on plant development, biomass yield, and nutrient availability. Two different processing modes of sludges (digested dewatered and pelletized-heat dried) applied at two rates, 10 and 20 Mg ha -1 were compared with inorganic N and a zero-N control. Plant height, basal stems diameter and biomass production increased slightly with the sewage sludge treatments but in different manners depending on the kenaf cultivar in question. Both sludges were similar in their ability to supply N to the plants. Apparent N recovery and N fertilizer equivalent value were greater in the low dosage treatments. Of the two cultivars, 'Everglades 41' showed greater mean values for all the variables studied. No differences were found in leaf P, K, Ca, Mg contents among treatments. The Zn and Cu concentrations were the only trace elements that increased in the leaf tissues with sludge application, although the values recorded were well below critical environmental thresholds.Additional key words: biomass yield, digested dewatered sewage sludge, dried-pelletized sewage sludge, fertilizer value, Hibiscus cannabinus, nutrients, trace elements. ResumenProducción de biomasa y contenido en nutrientes de kenaf cultivado sobre un suelo enmendado con lodos de depuradora La eliminación de los lodos de depuradora supone un gran problema, debido al estricto control de los tratamientos de aguas residuales. El reciclado como fertilizante es una opción muy atractiva tanto económica como medioambiental. Es importante evaluar la capacidad de estos residuos para aportar nutrientes en dosis suficientes a los cultivos sin causar daños medioambientales. Se diseñó un estudio en invernadero con dos cultivares de kenaf ('Everglades 41' y 'Tainung 2') para evaluar los efectos de dos técnicas diferentes en el proceso de secado de lodos (deshidratado por centrifuga y secado térmico-pelletizado) sobre el desarrollo de la planta, la producción de biomasa y la disponibilidad de nutrientes. Se aplicaron dos dosis de lodos (10 y 20 Mg ha -1 ), que fueron comparadas con un aporte de N inorgánico y con un control sin fertilizar. Los tratamientos con lodos aumentaron ligeramente la altura de la planta, el diámetro del tallo y la producción de biomasa, pero de forma diferente según el cultivar. La capacidad de aportar N a las plantas fue similar en los dos tipos de lodos. Los valores de recuperación aparente de N y de equivalentes de fertilizante nitrogenado fueron mayores en las do...
