“…Reduction in the need for N fertilizer inputs with application of animal manures has been oft observed due to significant N mineralization (Eghball, 2000; Jokela, 1992; Mitchell & Tu, 2005; Tewolde, Sistani, Feng, & Menkir, 2019). Determining the appropriate level of N fertilizer reduction with animal manure application is complicated by source of manure, variation in nutrient concentration of manures from the same source, handling of manure prior to application, and weather conditions following application that affect decomposition and release of nutrients (Eghball, Wienhold, Gilley, & Eigenberg, 2002; Larney & Hao, 2007; Zavattaro et al., 2017). Summarizing this comparison, application of organic amendment was manifested in greater soil organic C and N fractions (particularly net N mineralization and soil‐test biological activity) that contributed to effective nutrient cycling and reduced the need for synthetic N inputs.…”

Production of corn (Zea mays L.) requires significant N availability to reach maximum yield potential. Nitrogen fertilizer recommendations generally have ignored sitespecific conditions and have focused more on total N demand for representative soils across a region. Recent evidence suggested that site-specific conditions of the biologically active component (0-10-cm depth) could inform the magnitude of yield response to applied N fertilizer. This approach was tested further on 111 fields in Coastal Plain, Piedmont, and Blue Ridge regions (states of North Carolina, South Carolina, and Virginia). Plant-available N (sum of residual inorganic N and net N mineralization during a 24-d aerobic incubation) was inversely proportional to economically optimum N rate scaled to grain production level (r 2 = .47, p < .001). Soil-test biological activity as a simple, rapid, and reliable indicator of net N mineralization was also predictive of economically optimum N rate (r 2 = .46, p < .001) and validated an earlier assessment. Greater soil-test biological activity was obtained from private farms than from research stations (259 vs. 172 mg C kg −1 3 d −1 , respectively; p < .001), as well as from fields with minimum tillage, multi-species cover cropping, and amendment with animal manures. Results imply that some farmers are making choices to improve soil health condition and these choices can lead to lower requirement for N fertilizer inputs.

Alternative management practices such as no‐tillage compared to conventional tillage are expected to recover or increase soil quality and productivity, even though all of these aspects are rarely studied together. Long‐term field experiments (LTEs) enable analysis of alternative management practices over time. This study investigated a total of 251 European LTEs in which alternative management practices such as crop rotation, catch crops, cover crops/green manure, no‐tillage, non‐inversion tillage and organic fertilization were applied. Response ratios of indicators for soil quality, climate change and productivity between alternative and reference management practices were derived from a total of 260 publications. Both positive and negative effects of alternative management practices on the different indicators were shown and, as expected, no alternative management practice could comply with all objectives simultaneously. Productivity was hampered by non‐inversion tillage, FYM amendments and incorporation of crop residues. SOC contents were increased significantly following organic fertilizers and non‐inversion tillage. GHG emissions were increased by slurry application and incorporation of crop residues. Our study showed that alternative management practices beneficial to one group of indicators (e.g. organic fertilizers for biological soil quality indicators) are not necessarily beneficial to other indicators (e.g. increase of crop yields). We conclude that LTEs are valuable for finding ways forward in protecting European soils as well as finding evidence‐based alternative management practices for the future; however, experiments should focus more on biological soil quality indicators as well as GHG emissions to enable better evaluation of trade‐offs and mutual benefits of management practices.

“…Studies have revealed that the average characteristics of cattle manure expressed as percentages of dry matter are as follows: 1.034 ± 0.029 for density, 2.40 ± 1.84 for ammonia N, 2.04 ± 0.86 for organic N, 41.51 ± 5.53 for C, and 11.74 ± 4.73 for the C/N ratio [50]. Compared to mineral N fertilizers, bovine manure (farmyard manure and slurry) is slightly less effective for crops, but it has been determined that it increases soil organic carbon (SOC) and soil N, helping long-term soil fertility maintenance [51].…”

Natural Organic Compounds for Application in Organic Farming

Chemical fertilizers, pesticides, and fungicides are widely used in agriculture to improve crop yields. Most of the compounds used are synthetic, and their overuse causes environmental pollution and human health problems. Currently, several countries are working to reduce the use of agrochemicals. Organic agriculture is now emerging as a sustainable alternative to traditional agriculture using environmentally friendly strategies such as the application of organic fertilizers from plant and animal waste and pesticides based on plant extracts and microbials. However, the availability of commercial biopesticides and organic fertilizers is very limited because there are certain barriers to the commercialization of biological products. These barriers include small available quantities of raw materials and strict registration laws requiring toxicological tests and other studies that are expensive and time consuming. The objective of this review is to provide details about the various organic fertilizers and pesticides that do not have the same disadvantages as synthetic compounds in terms of persistence and toxicity.
