Effect of Liquid Pig Manure and Chemical Fertilizers on Shoot Growth and Nitrogen Status of Young “Fuyu” Persimmon Trees

Abstract

Liquid pig manure (LPM), digested from pig slurry, has been used as a nutrient source substituting chemical fertilizer (CF) for some crops. This experiment was conducted to evaluate the effect of different levels of CF and LPM in early July on nitrogen (N) uptake of pot-grown young "Fuyu" persimmon (Diospyros kaki). The total N and potassium (K) from CF and LPM applied to a 3 L pot were 1.2 g N and 1.15 g K for the low and 2.4 g N and 2.3 g K for the high level. From 2 weeks after the applications, secondary shoots started to grow for the CF but none for the LPM. Two nutrient sources did not significantly affect the amount of N increase in different tree parts from July 1 to August 6. At the high level, tree total N increased by 80% from 551 mg for the CF and by 31% from 583 mg for the LPM. The nutrient sources did not affect soil pH. The soil that received LPM contained more organic matter (P = 0.048), available phosphorus (P) (P = 0.002), and exchangeable K + (P = 0.001) and Mg 2+ (P = 0.009) than the soil that received CF on August 6. These results indicated that N in LPM becomes available later but its effect is more durable than CF.

Damages of Young Persimmon Tree as Affected by Application of Immature Liquid Pig Manure

“…The LPM has widely been applied in rice paddy as a basal fertilizer (Hong et al, 2010;Jeon et al, 2003) in Korea. Also in horticultural crops including fruit trees, previous studies have confirmed there was no difference in growth and quality of the crops between chemical fertilizer and LPM when they were properly applied (Lim et al, 2008;Lim et al, 2009;Park et al, 2012;Lee and Seong, 2015;Choi et al, 2017). Some persimmon growers have tried the LPM but it has not yet been widely used in the orchards due to several difficulties including little information about effects of the LPM.…”

Different organic material amendments effects soil nitrogen utilization and crop yield in the North China Plain

“…The simultaneous application of organic fertilizers and CFs could increase soil moisture, improve soil organic matter content, maintain soil nutrient balance, and increase crop yields (Abbasi et al., 2013). Manure is important in providing nutrient supplies because it contains nutrients necessary for the production of many crops (Choudhary et al., 1996; Choi et al., 2017; Kim et al., 2013). For instance, cow ( Bos taurus ) and chicken ( Gallus domesticus ) manure returned to the field increased the N content and its uptake of N by cocksfoot ( Dactylis glomerata L.); moreover, the best results were obtained after the application of chicken manure (Kuziemska et al., 2021).…”

Factores de interacción microbio-sustrato y gas-microbio en relación con la digestión anaeróbica del estiércol líquido y la productividad del cultivo

“…LM are therefore, organic fertilizers formed by mixing and dissolving factory waste, crop residues, urine, green manures, sawdust, market waste, animal dung, household/kitchen waste, mushroom waste, agro-industrial wastes and farm residues, among othersby way of fermenting and/or decomposing them (Ansar et al, 2021;Elaiyaraju & Partha, 2016;Rana, n.d.;Supriya & Harish, 2019). In various farmlands, the efficiency of LM in growing certain types of crops compared to chemical fertilizers, has been studied with near 100% success by many researchers (Alamene & Howells, 2022;Antoneli et al, 2019;Arunkumar et al, 2021;Byeon et al, 2021;Choi et al, 2017;Gajjela et al, 2018;Msibi et al, 2014). In whatever form (solid, semi-solid or liquid form), manures have the potential of polluting water bodies and the surrounding air, by causing GHG emissions, ground water pollution, leaching of pollutants, soil salinization and eutrophication of surface water (Ahlberg-Eliasson et al, 2021;Antoneli et al, 2019;Camilleri-Rumbau et al, 2021).…”
