A Poultry Litter-Derived Organomineral Phosphate Fertilizer Has Higher Agronomic Effectiveness Than Conventional Phosphate Fertilizer Applied to Field-Grown Maize and Soybean

Abstract

Inadequate disposal of poultry litter (PL) may promote eutrophication of water bodies due to its high nutrient content, including phosphorus (P). Thus, recycling P from PL to produce organomineral fertilizer (OMF), reduces the dependence on finite mineral P reserves, and also reduces P losses from soil. In this context, a field experiment was carried out to assess the agronomic effectiveness of a granular PL-derived OMF applied to maize and soybean in a highly weathered tropical soil. OMF was compared to single superphosphate (SSP) at five P rates between 0 and 70 kg ha−1. The shoot dry weight (SDW) and grain yields of soybean and maize were affected by P rates; however, no difference between OMF and SSP was found. A similar trend was observed for soil P and P uptake. The leaf P content and soil pH were not affected by either P sources or P rates. Although there was no difference between OMF and SSP on the crop yields, OMF had the highest relative agronomic effectiveness based on the SDW. These results show that the production of granular OMF from PL is a viable alternative to conventional P fertilizers and reduces the dependence of mineral P reserves.

Possibilities of Climate Control of Poultry Complexes through Co-Combustion of Poultry Waste–Solid Biomass for Agriculture in Romania

“…In addition to obtaining energy [19,20] or biofuels [21,22], poultry waste treatment is also necessary in order to ensure environmental protection, as well as alternative fertilizers to the chemical ones [23,24], to reduce the eutrophication of water bodies [25,26], the pathogen contamination risk [27], heavy metals, or arsenic [28]. The value of poultry manure-derived biochar as soil fertilizer is shown by different studies analyzing its effects on various cultures like tomatoes [29], maize, and soybeans [26].…”

Biochar-Based Phosphate Fertilizers: Synthesis, Properties, Kinetics of P Release and Recommendation for Crops Grown in Oxisols

“…Increasing SOM levels takes a long time and is an enormous challenge in the tropical landscape due to the high SOM decomposition rate and low input of organic residues in crop fields of most tropical soils [1,2]. However, the similar beneficial effects of SOM on the soil P availability and plant nutrition could be reached through the use of organomineral fertilizers (OMFs), although the agronomic effectiveness of this fertilizer class relies on soil type, notably on the native SOM level [4][5][6][7][8].…”

“…This effect was demonstrated due to a greater uptake by maize of P derived from OMF over monoammonium phosphate (MAP)-fertilized plants, in which the fertilization recommendation was based on the fertilizer P soluble in neutral ammonium citrate plus water (NAC+H2O). Other forms of P in OMFs, which is not fully assessed by the NAC+H2O solution, underestimates the P rate recommended for crops [5]. Moreover, due to a more gradual release of P from different P pools found in organicbased fertilizers, OMFs can promote a higher P residual effect (soil residual P) than mineral fertilizers [6,7].…”

“…On the other hand, tropical soils tend to be poor in N, P and K (Isah et al, 2020 ). Thus indicating that after use as poultry litter, this material can be composted and used as a natural fertilizer in agriculture (Frazão et al, 2021 ), once again promoting sustainability and making production cheaper, since Brazil has large agricultural areas, being one of world’s leading producers and suppliers of food, fibers and bioenergy (Fao, 2017 ) and is highly dependent on imported fertilizers, mainly from Russia, which makes this research highly important for the Brazilian agricultural sector.…”
