“…Fertilization is one of the most key driving forces in agriculture and play important role in crop grain yield formation [12][13][14] and farmers in general apply a high dose of chemical fertilizers during wheat production to harvest high grain yields [7,15,16]. However, the long-term unnecessary use of compound fertilizers in agricultural farming has unanticipated environmental impacts, including degradation of soil fertility, organic matter absorption and decreased water holding capacity (WHC), nutrient mobilization, and uptake by root zone [3,17].…”

The effects of long-term incorporation of organic manure and biofertilizers have been investigated on winter wheat in the North China Plain (NCP). The five-year field experiment (2013–2018) has illustrated the responses of grain yield and yield components. Seven fertilization approaches, included pig farm-yard-manure and biofertilizers amendments combined with five NPK% drop levels of chemical fertilizer ratio + organic fertilizer + biofertilizer (0, C+O+B) 25%, CL4; 50%, CL3; 75%, CL1; and 100%, CL0), without fertilizer as control (CK), in NCP during the years 2013–2018. Results showed that the grain yields of CL1 and CL2 were equivalent to CL0 in all growing seasons except 2014/2015. The grain yields of CL4 were 29.9% to 46.6% lower than that of CL0 during 2014/2015, 2016/2017, and 2017/2018. The valuable spike-number, grain number per-spike, and 1000-grain weight showed significant variations among different growing periods. Regression analysis of grain yield and yield components indicated that number grains per-spike showed significant increase in seed yield formation. The 1000-grain weight was the major parameter that influenced yield of moderate and low yielding periods, respectively. The results revealed that application of 30 m3 ha−1 pig farm-yard-manure and 20 kg ha−1 biofertilizers has reduced at least 50% of the NPK fertilization without dropping grain yields in the North China Plain.

“…In contrast, crop residue with a high C/N ratio stimulates net N immobilization, leading to a lower risk of NO 3 − leaching [90]. Previous studies have indicated that applying organic manure [91] or mineral N fertilizer [92] with straw (high C/N ratio) into cultivated soils reduced the accumulation of NO 3 − in the soil, since soil microbes use labile C contained in straw as an energy and carbon source with rapid microbial N immobilization [93,94], thus decreasing NO 3…”

Biogas - Recent Advances and Integrated Approaches

View full text Add to dashboard Cite

For sustainable agriculture, it is important to manage agricultural wastes, such as crop residues and livestock wastes. Anaerobic digestion has been gathering the attention to recycle these wastes into renewable energy (biogas) and fertilizer (soil amendment) (digestate). Dry anaerobic digestion is defined as digestion at higher than 20% of total solid (TS) content in the reactor, which is suitable for wastes with high TS content, such as agricultural wastes. In this chapter, we reviewed recent advances in biogas production and use of digestate as soil amendment from dry anaerobic digestion of agricultural wastes. It has been found that ammonia concentration, feed/inoculum (F/I) ratio, and TS content are important parameters for operation of dry anaerobic digestion. Several operation technologies have been in operation, while new operation strategies have been developed. Application of solid digestate into the soil is beneficial to increase soil properties; however it should be carefully operated because it has risks of nitrate leaching and soil pathogens.

“…Exchangeable Ca (23.8 to 41.2 mg kg -1 ) were significantly higher in amended soil. It was reported that animal manure raises the pH value (Whalen et al, 2000, Gai et al 2018) and therefore, lowers the availability and toxicity effect of metal present in the soils (Tang et al, 2007). Lambs were fed with grass and CaO processed corn ("nixtamal") that explains the high levels of Ca and Mg in the manure.…”

“…It is well established that crop production on acid soils can be significantly risen when the soil is commonly amended with manure (Whalen et al, 2000, Gai et al, 2018 which reduces toxicity of some heavy metals, stimulating plant growth and increasing the yield of crops. pH improves plant-availability of macronutrients while reduces the solubility of Al and Fe.…”

The waste amendment is a common practice to improve crop production on acid soils. This work aims to study the effectiveness of water potabilization plant sludge and lamb manure in acid soils remediation and the possible absorption of metals in cultivated lettuces, as well as the elements´distribution in roots and leaves after extra-contaminated irrigation. Al2(SO4)3-stabilized sludge, and lamb manure was added to an acid soil collected from Huasca de Ocampo, Hidalgo State, Mexico. The sludge (L), manure (M), control soil (C), unamended (S) and amended soils (SML) were characterized, and the metals´ concentrations determined. The SML was prepared by adding 2.62 % M and 5.25% L to fill up 600 L tanks. Lettuces (Lactuca sativa var. longifolia) seeds were sown in S and SML, and irrigated once by metal salts solution (Na, Mg, Ca, Fe, Ni, Cu, Zn, and Cd as sulfates, 200 mg kg-1 each). Lettuce germinated and grew satisfactorily in the SML, but they grew slowly in the unamended acid S, and the roots were affected. Leaves and roots were regularly analyzed along three months, and the metal concentrations showed higher values in S than the ones in SML. Pollutants were available from S, as they were present in roots, and desorbed after 40 days. The elements were present in higher concentrations in lettuce roots than in leaves, as expected. Conclusions. a) Acid soils can be amended with potabilization plants wastes in mining zones, but pH must be controlled to prevent the availability of metals. b) The soil texture was the principal cause of infertility due to root damage, and wastes eliminate the impairment. c) The element concentrations present in the leaves were acceptable for human nutrition.
