“…Compared to the Control, N uptake was significantly increased by the application of frass. This high short-term ability to supply N contrasts with other organic amendments which usually supply N more slowly (Delin et al, 2012;Cassity-Duffey et al, 2020). The amount of N released to plants by organic fertilizers depends on their chemical composition, including N content, C:N ratio, and contents of labile C, hemicellulose, cellulose, and lignin (Gutser et al, 2005;Mohanty et al, 2011).…”

The forecasted growth of insect production in the next few years will generate high quantities of frass (insect excreta). Although frass is increasingly considered a potential fertilizer, the dynamics of nutrient supply by frass is still poorly understood. Here, we aimed at gaining insight into the short-term fertilizer value of frass from mealworm (Tenebrio molitor L.) in order to optimize its sustainable use in agroecosystems. Using a short-term pot experiment, we showed that, even though frass has a great potential to be used as a substitute of mineral NPK fertilizer, its N fertilizer potential is mediated by its rate of application. At 10 t ha−1, due to its fast mineralization coupled with improvement in microbial activity (assessed using Biolog EcoPlate), frass was as effective as mineral fertilizer to supply N to plant. By contrast, at 5 t ha−1, the lower frass mineralization induced a reduced N uptake compared to its mineral control. Unlike N, frass was as effective as mineral fertilizer to supply P and K to plants irrespective of its application rate. This was attributed to the presence of P and K in a readily available form in frass. Taken together, our results indicate that mealworm frass supplies very rapidly N, P and K to plants but its effects on N dynamics should be better investigated to warrant its sustainable use as an alternative fertilizer for managing NPK nutrition in cropping systems.

“…In the case of yard waste compost, the amount of N mineralized is low, so that small differences among samples analyzed over time from the same material can have a strong effect on EF. In fact, the amount of yard waste compost N in the mineral form did not always follow a smooth pattern over the course of the incubation (e.g., Cassity-Duffey et al, 2020;Lazicki et al, 2020;Masunga et al, 2016). This is likely due to small differences across samples analyzed and is unavoidable when a different sample is analyzed for each time point during the incubation.…”

“…Similarly, composts may be made from different types of green waste and manures. A challenge when applying these amendments is that their nutrient availability is often not known (Cassity-Duffey et al, 2020;Lazicki et al, 2020). Furthermore, the amount of nutrients available and the timing of when they become available may differ among materials from different suppliers and even across batches from the same supplier (Lazicki et al, 2020).…”

Nitrogen mineralization from organic fertilizers and composts: Literature survey and model fitting

et al. 2021

Organic fertilizers and composts are valuable sources of nutrients. However, their nutrient availability is often not known and can be variable. The objective of the present study was to collect net nitrogen (N) turnover data from peer-reviewed articles and fit a model that simulates gross N mineralization and gross N immobilization to determine pool sizes and their rate constants of different common organic amendments. A total of 113 datasets were included in the study. The model predicted that 61 and 72.5% of total N in feather meal and guano, respectively, would be in the mineral form after 100 d under optimal conditions. Nitrogen availability from poultry manure and poultry manure compost was lower. On average, 16-17% of total N was present as mineral N in the materials, whereas at the end of the 100-d simulation, 39.6 and 32.7% of total N from an average poultry manure and its compost, respectively, were in the mineral form. Yard waste compost and vermicompost are stable materials, with <10% of the total N in an average material being in the mineral form at the end of the 100-d simulation. Model simulations revealed that changes in the assumed temperature sensitivity of N mineralization have a strong effect on N availability of readily available organic amendments during the first weeks after incorporation. The model performed well for guano and feather meal but was unsatisfactory for the other amendment groups. Model performance may have been hampered by different incubation protocols used in the studies included and variability in amendment properties not considered by the model. The results of this study allow estimating the release of N from a variety of organic fertilizers and composts and can be a valuable tool to improve N management of organic amendments in crop production.

Organic nitrogen fertilizer sources for field production of flue‐cured tobacco (Nicotiana tabacum L.)

et al. 2022

Despite rapid expansion of organic tobacco (Nicotiana tabacum L.) production in the US, limited research has been conducted comparing the numerous organic fertilizer sources. Organic flue‐cured tobacco traditionally relies on feather meal as the organic N fertility source, as it is readily available, but there is limited information on alternative organic N fertilizers. The objective of this research was to investigate seven different organic fertilizer sources to determine their effect on the growth and development of flue‐cured tobacco. From 2018 to 2019, field sites were established at four locations in North Carolina. Fertilizer treatments included sodium nitrate, composted layer manure, feather meal, corn gluten, soy protein, blood meal, and seabird guano. Both years, these organic N treatments were banded at sidedress (10 d after transplanting) at a rate of 78 kg total N ha−1. Sodium nitrate resulted in higher foliar nitrate‐N concentration than composted layer manure at layby and higher cured leaf yield compared with feather meal and composted layer manure. However, soy protein and seabird guano were often similar to sodium nitrate in yield response and resulted in higher yields when compared with other sources of organic N, such as feather meal and composted layer manure. While feather meal and composted layer manure resulted in a 10 and 11% reduction in yield, respectively, there was no significant difference in tobacco value among treatments. Our results suggest that organic tobacco farmers have other options for N selection beyond the current feather meal standard.
