“…MN17, provides a cost-effective, environmentally friendly way of increasing yield and of reducing the Cd content of pea plants growing in Cd-contaminated soil. These results support published studies on other species showing that organic and inorganic soil amendments and microbial inoculation can improve plant growth on heavy metal contaminated soil [12,15,33,[44][45][46]. Amongst the properties of biochar and gravel sand are that they adsorb Cd onto their surfaces and make it less available to plant roots [47,48].…”

Contamination of soils with heavy metals, particularly cadmium (Cd), is an increasingly alarming environmental issue around the world. Application of organic and inorganic immobilizing amendments such as biochar and gravel sand in combination with metal-tolerant microbes has the potential to minimize the bioavailability of Cd to plants. The present study was designed to identify the possible additive effects of the application of Enterobacter sp. MN17 as well as biochar and gravel sand on the reduction of Cd stress in plants and improvement of growth and nutritional quality of pea (Pisum sativum) plants through the reduction of Cd uptake. Pea seeds were surface sterilized then non-inoculated seeds and seeds inoculated with Enterobacter sp. MN17 were planted in artificially Cd-polluted soil, amended with the immobilizing agents biochar and gravel sand. Application of biochar and gravel sand alone and in combination not only improved the growth and nutritional quality of pea plants by in situ immobilization but also reduced the uptake of Cd by plant roots and its transport to shoots. However, microbial inoculation further enhanced the overall plant health as well as alleviated the toxic effects of Cd on the pea plants. These soil treatments also improved rates of photosynthesis and transpiration. The combined use of biochar and gravel sand with bacterial inoculation resulted in an increase in plant height (47%), shoot dry weight (42%), root dry weight (57%), and 100 seeds weight (49%) as compared to control plants in Cd contaminated soil. Likewise, biochemical constituents of pea seeds (protein, fat, fiber, and ash) were significantly increased up to 41%, 74%, 32%, and 72%, respectively, with the combined use of these immobilizing agents and bacterium. Overall, this study demonstrated that the combined application of biochar and gravel sand, particularly in combination with Enterobacter sp. MN17, could be an efficient strategy for the remediation of Cd contaminated soil. It could support better growth and nutritional quality of pea plants.

“…The shorter growing season often leads producers in colder regions to apply larger amounts only one or two times per season. Conversely, regions with longer growing seasons may apply fertilizer, both manure and synthetic, more often at smaller rates, effectively reducing N losses without a yield penalty, thereby improving N use efficiency (Huang et al, 2016).…”

wine production is a major industry worldwide, contributing to the global economy and food security. In 2017, the United States produced over 72 million swine (USDA-NASS, 2019), resulting in an estimated 100 million Mg of manure (USEPA, 2013). Overall, this manure likely contains more than 0.85 million Mg nitrogen (N), 0.3 million Mg of phosphorus (P), and 0.48 million Mg of potassium (K) (Hatfield et al., 1998). Land application of manure utilizes these nutrients to meet crop demand, reduces the need for supplemental synthetic fertilizer, and removes the need for alternative disposal practices. Swine manure application has the potential to increase crop yields (Wortman et al., 2017; Choudhary et al., 1996) but may also be associated with negative impacts to environmental quality, such as increased nutrient leaching (Choudhary et al., 1996) or increased ammonia emissions (Chantigny et al., 2007). Much of the uncertainty regarding swine manure application as fertilizer comes from divergent findings in the literature. For example, Schlegel et al. (2015) evaluated soil physiochemical properties after 10 yr of swine manure application and found that swine manure did not affect soil P, soil N, soil C, organic matter, or electrical conductivity. However, other evidence suggests that repeated manure applications increases soil nutrients and subsequent risk of losses through leaching, runoff, or gas emission (Ball-Coelho et al., 2004; Shepherd and Newell-Price, 2013). Many of these inconsistencies stem from differences in site-specific characteristics, such as application rates, crop management systems, climate, and soil properties. In these circumstances, meta-analytic techniques may be used to evaluate the results of independent studies while accounting for a wide range of experimental conditions. The objective of this study was to conduct a metaanalysis to compare the effects of swine manure and synthetic fertilizer on both a measure of production, crop yield and a measure of environmental quality, nitrous oxide (N 2 O) emissions.

“…The use of PS as a nutrient source for rice cultivation could be a form of local supply with high reserves that would allow recycling and reduce management problems associated with increasing local livestock waste. Some studies have reported the potential use of PS as an alternative fertilizer for rice ( Pan et al., 2009 ; Huang et al., 2016 ; Moreno-García et al., 2017 ).…”

IntroductionRice heavily relies on nitrogen fertilizers, posing environmental, resource, and geopolitical challenges. This study explores sustainable alternatives like animal manure and remote sensing for resource-efficient rice cultivation. It aims to assess the long-term impact of organic fertilization and remote sensing monitoring on agronomic traits, yield, and nutrition.MethodsA six-year experiment in rice fields evaluated fertilization strategies, including pig slurry (PS) and chicken manure (CM) with mineral fertilizers (MIN), MIN-only, and zero-fertilization. Traits, yield, spectral responses, and nutrient content were measured. Sentinel-2 remote sensing tracked crop development.ResultsCost-effective organic fertilizers (PS and CM) caused a 13% and 15% yield reduction but still doubled zero-fertilization yield. PS reduced nitrogen leaching. Heavy metals in rice grains were present at safe amounts. Organic-fertilized crops showed nitrogen deficiency at the late vegetative stages, affecting yield. Sentinel-2 detected nutrient deficiencies through NDVI.DiscussionOrganic fertilizers, especially PS, reduce nitrogen loss, benefiting the environment. However, they come with yield trade-offs and nutrient management challenges that can be managed and balanced with reduced additional mineral applications. Sentinel-2 remote sensing helps manage nutrient deficiencies. In summary, this research favors cost-effective organic fertilizers with improved nutrient management for sustainable rice production.
