“…Soil fertility is influenced by the parent materials, climate, vegetation, and human activities (Dawe et al, 2003; Hussain, Olson, Wander, & Karlen, 1999; Mu et al, 2018). The vegetation coverage in our study area showed a gradual decrease with increasing latitudes in Yan ' an, followed by a forest vegetation belt, grassland vegetation belt, and sandy vegetation belt.…”

“…At present, about 33,330 ha of new flat farmland has been created in Yan'an city for an investment of 5 billion RMB from 2013 to 2017 (He, 2015; Liu, Du, et al, 2015). However, engineering measures such as deep tillage, barren soil cover, heavy machinery use, and land leveling adopted by land consolidation also destroy the physical and chemical properties of the soil (Liu et al, 2013; Liu, Du, et al, 2015; Mu, Fu, Liu, Yu, & Wang, 2018). Therefore, whether this large amount of newly created farmland is suitable and fertile for crop growth is unknown.…”

The farmland area on the Loess Plateau has decreased because of the Grain for Green Programme and other soil conservation measures. The Gullies Reclamation for Farmland Project has been implemented to increase the farmland areas. Many farmlands have been created, but their suitability for Note for his deletion: because of duplication crop production and sustainable management practices is unknown. Topsoil was sampled from 119 sites to evaluate the soil fertility parameters (e.g., SOM, nitrogen, phosphorus, clay). We found that (a) overall fertility was lower than the soil fertility III level criterion of Shaanxi Province except for the potassium due to the loess parent materials where nutrients were at low levels except for potassium and was extremely unfavorable for crop growth; (b) the distribution of soil fertility properties and quality were variable on the Yan'an regions and especially lowest in the northern areas because of slightly precipitation and vegetation coverage, as well as lack of SOM, nitrogen and phosphorus; (c) cultivation was the better choice for soil fertility restoration at short-term in view of the higher enzyme activities and the contents of SOM, nitrogen, and phosphorus. The minimum data set for this type of soil quality analysis was determined to be SOM, CEC, NaHCO 3-P, Clay, DTPA-Fe, DTPA-Zn, and SUE. We recommend to planting of Medicago sativa and other legume crops in the uncultivated newly created farmland rather than letting it recover naturally. It is necessary to apply organic fertilizers, chemical fertilizer, and micro-elements simultaneously and not rely solely on chemical fertilizers in the utilization of newly created farmland.

“…The assessment of the multi-criteria evaluation system IFI The assessment of soil fertility is a useful system that helps to improve sustainable land use management. IFI is an effective and important indicator for assessing the quality and degradation of arable land (Mu et al 2018;Shang et al 2014). In this study, we calculated the integrated IFI based on TOM, Av-P, and Av-K parameters using a weighted function…”

“…The current international and national quality evaluation systems of arable land tend to focus more on production capability, land potential, and ecological quality and sustainability (Fu and Bai 2015). However, the implementation practices often only consider one single criterion, such as the soil integrated fertility index (IFI) (Brejda et al 2000;Mu et al 2018;Wang et al 2001). The lack of a comprehensive evaluation standard results in noncomparable evaluation results.…”

This study proposed a multi-criteria evaluation system for arable land resources by combining the soil integrated fertility index (IFI) with a soil cleanliness index (based on heavy metals and metalloid content). A total of 16 typical arable land units in Chongming District, China, were evaluated using the proposed evaluation system based on 104 collected soil samples in 16 towns. The comprehensive soil evaluation scores of arable lands in 16 towns were in the range of 90.7 to 99.2 with a mean of 96.2, indicating that the arable land in all 16 towns was at the level of excellent (≥ 90.0). Lower cleanliness indices had a significant impact on the final evaluation score. In comparison with singleindex evaluation systems (i.e., the IFI or soil cleanliness index), the proposed multi-criteria system better reflects the quality of the soil. In the practice of arable land requisition and subsidy policy, the proposed multicriteria evaluation system not only encourages farmers to preserve arable lands during farming but also helps agricultural authorities make effective and reliable management decisions.

“…-green production and increasing soil fertility; -energy saving production. Perhaps the task of improving fertility [1][2][3][4][5][6] is one of the highest priorities, because the health of the entire population of the Earth depends on it. It is known that a number of factors influence human health: heredity, which accounts for 20 % and human lifestyles -80 %, of which 57 % are the quality of food consumed.…”

Results of studying the effects of biological products on accelerating the decomposition of the crop tailings

et al. 2020

The article presents investigations aimed at addressing issues of utilization of the tailings of the crop as a fertilizer. It is known that the by-products of crop production left on the field interfere with the subsequent agricultural operations, and when used as a fertilizer it has a long decomposition period, which is accompanied by putrefactive processes with the release of phenolic compounds which inhibit subsequent plants. To accelerate the process of humification of plant residues, nitrogen-containing fertilizers are used, but recently biological preparations have become widespread, allowing the grain to be completely decomposed in 3–4 months. The authors propose a design of the machine that allows combining the operations of grinding the tailings of the crop with the introduction of bio preparations to speed up the decomposition process. The article presents the results of this machine field tests using various bio preparations: Agrinos 1, Sterniphag SP, humic preparation Ecorost and Biocomplex BTU. According to the linen method, the effect of the preparations on the activity of cellulose-decomposing bacteria was assessed. The dynamics of the activity of biological preparations was not linear and was largely dependent on weather conditions. The hotter temperature and the absence of abundant precipitation in August – September 2018 did not contribute to the active work of the soil biota and in the first report period the best decomposition of linen was in the variant with Biocomplex BTU and Sterniphag, respectively 3.6 and 3.3 %. On the 236th day of the experiment, the picture changed and the variants with Agrinos 1 and Ecorost showed the best performance, the decomposition was 21.2 and 21.9 %, respectively.
