“…Additionally, manure application typically provides the greatest benefit in systems with low or depleted SOM (Chen et al, 2018). Thus, SOM increased in the Bsk climate classification (cold semiarid steppes; Peel et al, 2007), in which soils frequently have low SOM (Halvorson et al, 2016b; Weyers et al, 2017). Similarly, SOM stocks may be depleted in corn systems (both silage and grain) compared with small grain, increasing the benefit of manure application.…”

Core Ideas Dairy manure matches synthetic fertilizer in yield and quality of row crops. Manure application increases soil organic matter and soil P levels. Appropriate application rates are critical to avoid negative environmental impacts. Dairy production systems rely on row crop agriculture to produce feed because animal density continues to rise, whereas land allocated to dairy farms is decreasing. Management of the entire dairy system, including animals, forages, and manure, must be optimized to meet production goals while remaining economically viable. Many producers apply dairy manure to meet crop nutrient demand, both reducing the need for synthetic fertilizer and the cost associated with manure disposal. However, repeated manure applications have been linked with environmental concerns, such as soil nutrient loading, increased greenhouse gas emissions, and decreased water quality. The objective of this research was to synthesize the literature comparing dairy manure fertilizer with synthetic fertilizer in row crop agricultural production systems to determine impacts on both crop productivity and environmental quality. Fifty‐eight studies were included in a meta‐analysis that showed that, when applied at rates providing comparable levels of plant‐available N, manure fertilizer matched synthetic fertilizer in crop production, quality, and digestibility. Manure application increased soil organic matter, which may have an overall positive effect on long‐term soil fertility, but it also increased soil P, suggesting a threat to water quality. Soil nitrate leaching and nitrous oxide emissions were highly variable across studies, so no clear trends were evident. Overall, these findings suggest that manure is a suitable fertilizer in row crop agriculture, but it should be applied with caution to limit risk to environmental quality, which can vary with site‐specific factors like climate, soil texture, and application practices.

“…Furthermore, it can release organic acids, which affect P availability by forming organometal complexes with calcium minerals, releasing P from apatite, and decreasing P sorption (Hosseinpur et al 2012;Schneider and Haderlein 2016;Gerdelidani and Hosseini 2018). Previous studies have revealed that when it is applied to soils, dissolved organic matter can enhance P levels in soil solutions (Perassi and Borgnino 2014;Sindelar et al 2015;Weyers et al 2017). Braschi et al (2003) explained that the addition of organic matter increased P content by inhibiting the formation of P minerals, although it did not influence P adsorption.…”

“…Mahmoud et al (2018) reported that the application of 10 t ha −1 citrus tree pruning biochar in calcareous soil treated with P fertilizer increased all P fractions to a greater extent than soil treated with biochar or P fertilizer alone. Weyers et al (2017) reported that the dissolved organic matter was enhanced in calcareous soils amended with manure. They demonstrated that the dissolved organic matter decreased the P sorption capacity of soil, thereby increasing the P concentration in soil solutions, which could cause surface water contamination.…”

Biochar has the potential to affect the cycle of phosphorus (P), but the underlying mechanisms of its effects remain poorly understood in calcareous soils. Our understanding of the effects of biochar is limited in calcareous soils during incubation. Therefore, this study was conducted to investigate how the availability and mineral fractions of P change after the addition of combined biochar and P fertilizer during incubation in calcareous soil. Sugarcane residue (raw SR) and biochar (400 °C for 2 h) were added to soils treated with 50 mg kg −1 of P, in the form of Ca(H 2 PO 4) 2 •H 2 O, at 0.5 and 1% (w/w). The soils were incubated at 25 ± 1 °C for 120 days. Available P (Olsen P) contents and mineral P fractions were measured after various incubation times (7, 30, 90, and 120 days). Biochar addition remarkably increased the amount of available P when compared with the raw SR treatment and the control condition (P < 0.05). After 30 days of incubation, the amount of available P in the soils decreased and remained unchanged thereafter. The results indicated that the addition of 50 mg kg −1 of P as fertilizer significantly augmented the labile P and P associated with Fe and Al in all the treatments at all incubation times (P < 0.05). In comparison with P treated with raw SR, P associated with Fe and Al was significantly enhanced after biochar addition (P < 0.05). Significant correlations were found for available P with labile P and P associated with Fe and Al. We found that biochar addition could increase available pools, thus improving available P concentrations at various incubation times. Therefore, we conclude that sugarcane residue biochar can enhance the available P in calcareous soils.

Nano and colloidal particles (1–1000 nm) play important roles in phosphorus (P) migration and loss from agricultural soils; however, little is known about their relative distribution in arable crop soils under varying agricultural geolandscapes at the regional scale. Surface soils (0–20 cm depth) were collected from 15 agricultural fields, including two sites with different carbon input strategies, in Zhejiang Province, China, and water-dispersible nanocolloids (0.6–25 nm), fine colloids (25–160 nm), and medium colloids (160–500 nm) were separated and analyzed using the asymmetrical flow field flow fractionation technique. Three levels of fine-colloidal P content (3583–6142, 859–2612, and 514–653 μg kg–1) were identified at the regional scale. The nanocolloidal fraction correlated with organic carbon (Corg) and calcium (Ca), and the fine colloidal fraction with Corg, silicon (Si), aluminum (Al), and iron (Fe). Significant linear relationships existed between colloidal P and Corg, Si, Al, Fe, and Ca and for nanocolloidal P with Ca. The organic carbon controlled colloidal P saturation, which in turn affected the P carrier ability of colloids. Field-scale organic carbon inputs did not change the overall morphological trends in size fractions of water-dispersible colloids. However, they significantly affected the peak concentration in each of the nano-, fine-, and medium-colloidal P fractions. Application of chemical fertilizer with carbon-based solid manure and/or modified biochar reduced the soil nano-, fine-, and medium-colloidal P content by 30–40%; however,the application of chemical fertilizer with biogas slurry boosted colloidal P formation. This study provides a deep and novel understanding of the forms and composition of colloidal P in agricultural soils and highlights their spatial regulation by soil characteristics and carbon inputs.
