Yield of soybean-wheat succession in no-tillage system and soil chemical properties affected by liming, aluminum tolerance of wheat cultivars, and nitrogen fertilization
“…Al toxicity causes root injury and therefore results in inhibition of root nutrient uptake and transport to the aboveground plant parts [6,8,16]. The present experimental results indicate soil Al toxicity is the main factor of Chinese hickory forest degradation caused by long-term application of nitrogen fertilize, which is consistent with previous studies [17,18]. It is speculated that part of the reason is that different forms of active Al dissolved from acidic soil block the cation channel.…”
This study explored the effects of soil acidification on degradation of Chinese hickory forest under field experimental conditions. Responses of plant nutrient absorption and non-targeted metabolomics based on LC-MS were analyzed to understand the mechanisms of Chinese hickory plant to acid resistance and susceptibility. In this field experiment, Chinese hickory plants were treated with CK (T1, control), nitrogen application (urea) (T2), and aluminum application (aluminum sulfate) (T3). Results showed that Al is the key toxic factor of acidification of soils planted with Chinese hickory. T2 and T3 treatments significantly inhibited absorption of nutrient elements (N, P, K, Ca, Mg, Cu, B and Zn) by Chinese hickory (except N in T2). The metabolomics data analysis showed that there were differences in plant metabolites between the experimental group (T2 and T3) and the control (T1), including p-coumaroyl quinic acid, chlorogenic acid, catechin, (+) germacrene A, myricetin 3-galactoside, and neoglucobrassicin. These metabolites may be the main regulators of Chinese hickory to soil acid stress or related to the effect of soil acidification on Chinese hickory resistance. KEGG metabolic pathway enrichment analysis showed that these differential metabolites were mainly enriched in four metabolic pathways: Flavonoid biosynthesis, Phenylpropanoid biosynthesis, Tyrosine metabolism, Stilbenoid, diarylheptanoid, and gingerol biosynthesis. This study provides a reference for metabolomics studies in Chinese hickory.

“…The research group consisting of Foloni et al [35] considered several problematic aspects of forecasting the yield of wheat and other grain crops due to the qualitative alignment of the processes of chemical tillage. According to a group of scientists, the increased acidity of the soil surface, combined with a lack of nitrogen, inevitably turns into problems for crops like wheat and barley, as well as other crops.…”
Ensuring the health and safety of crops through the mitigation of harmful microorganisms is essential for maintaining agricultural productivity and food security. The yield of grain crops constitutes a critical metric for optimizing agricultural planning. The primary objective of this research is to investigate the efficacy of integrating common programming principles with the employment of mineral fertilizers and enhanced plant protection to augment the yield of grain crops under the prevailing natural conditions of the Zhetysu region in the Republic of Kazakhstan. The methodological framework of this study is grounded in the application of practical, applied research methods to assess the potential of yield programming for wheat and barley. This assessment is contingent upon the utilization of fertilizers and plant protection products within the specific agro-climatic context of southeastern Kazakhstan. It was observed that the treatment of seeds with protective-stimulating agents significantly improves the health and viability of cereal crops. These benefits are evidenced by the suppression of infections and enhancements in germination rates and pest resistance. Field experiments conducted within the Zhetysu region indicate that the sowing of pre-treated seeds in late April is conducive to optimal plant development and yield. The findings suggest that further research should concentrate on refining the application of fertilizers and protective agents to enhance predictive models and yield outcomes at a national scale.
“…As noted, it is essential to evaluate the best way to apply lime and fertilizer when first cultivating soybeans. Therefore, at the end of this work it will be feasible to make productivity estimates regarding the main fertilization and liming practices used in cultivation thus, contributing to studies that aim to improve the technical recommendations offered to producers in the region (Fageria, 2001;Foloni et al, 2023).…”
Liming is the method in which limestone is applied to regulate the pH of the soil reducing its acidity and making the minerals labile. This study aimed to evaluate the management of liming using dolomitic limestone in sandy textured soils, on the development of soybean cultivation through a bibliographical survey. Sandy soil also, known as “light soil” is largely composed of sand and a smaller proportion of clay around 70% and 15% respectively, its grain size is higher, and the presence of nutrients is very scarce. Correcting soil acidity through liming is the first step towards obtaining a considerably productive crop, especially in recently cleared areas. Since in acidic soils, the limitation to plant development arises mainly from the indirect effects of pH. Therefore, it is necessary to analyze the soil continuously as well as the weather conditions in order to obtain the desired result. Several results have been observed in which the use of liming in acidic soils, mainly in the Brazilian Cerrado, reduces the toxic action of aluminum on the plant and promotes greater absorption of nutrients and micronutrients for the plants, in addition to maintaining the soil microbiota.
