AI Article Synopsis
- - The study focused on comparing the effects of traditional tillage and 6 years of conservation tillage (no-tillage with straw mulch) on the soil exchangeable base (SEB) in Zhangwu County, Liaoning Province.
- - Conservation tillage significantly improved the levels of exchangeable potassium (K), calcium (Ca), and magnesium (Mg) in the topsoil, indicating enhanced nutrient retention and soil health compared to traditional tillage.
- - Additionally, conservation tillage altered the ratios of K, Ca, and Mg in the soil, leading to increased vertical variability in these nutrients, which suggests a more dynamic soil structure in the plough layer.
Article Abstract
Taking the soil in Zhangwu County of Liaoning Province as test object, a comparative study was made to understand the composition of soil exchangeable base under traditional tillage and 6-year conservation tillage (no-tillage plus straw mulch). Comparing with traditional tillage, conservation tillage increased the total amount of exchangeable base (SEB) and the contents of exchangeable K, Ca, and Mg in top (0-15 cm) soil, suggesting its positive effect in increasing soil nutrient holding capacity and buffering ability. This effect had a close relationship with the changes of soil organic matter and clay contents, according to correlation analysis. In addition, the K/SEB and Ca/Mg ratios were higher, while the (Ca+Mg)/SEB, Ca/K, and Mg/K ratios were lower under conservation tillage than under traditional tillage, illustrating that the effects of conservation tillage on soil exchangeable base were mainly presented in the relative enrichment of soil exchangeable Ca and K, especially K. Conservation tillage increased the stratification ratio (0-5 cm/5-15 cm and 0-5 cm/15-30 cm) of soil exchangeable K, Ca, and Mg, and SEB, suggesting the increase of the vertical variability of SEB in plough layer.

Arbuscular mycorrhizal Fungi (AMF) are essential in agriculture and are often inter-linked with glomalin-related soil protein (GRSP) production which supports binding of aggregates, enhanced SOC and biological attributes. However, conservation agricultural practices in agroecosystem may have significant impact on AMF diversity, GRSP and soil quality-related parameters (SQRPs). This current experiment was implemented to gauge AMF conization percentage (AMF-CP), GSRP and significant changes on critical SQRPs, and to investigate the linkages between AMF-CP, GRSP and SQRPs as influenced by synergistic tillage and weed management in CA.

This study investigated soil fungal biodiversity in wheat-based crop rotation systems on Chernozem soil within the Pannonian Basin, focusing on the effects of tillage, crop rotation, and soil properties. Over three years, soil samples from ten plots were analyzed, revealing significant fungal diversity with Shannon-Wiener diversity indices ranging from 1.90 in monoculture systems to 2.

Conservation tillage and fertilization are widely adopted in agricultural systems to enhance soil fertility and influence fungal communities, thereby improving agroecosystems. However, the effects of no-tillage combined with manure on grain yield, nitrogen use efficiency (NUE), soil fertility, and rhizosphere fungal communities remain poorly understood, particularly in rainfed wheat fields on the Loess Plateau. A 15-year field experiment was conducted at the Niujiawa Experimental Farm of the Cotton Research Institute, Shanxi Agricultural University.

This article presents data measured in 44 farms covering a range of cropping practices, soil, and production parameters under contrasted types of crop management: conventional and conservation agriculture. Eighty-six winter wheat fields in Northwestern France were monitored for two growing seasons (2021-2023). The dataset encompasses data about cropping practices (tillage, soil cover, rotation, pesticide use, nutrition), soils (chemical, biological, and physical parameters, including texture), and grain production (nutritional, technological, and sanitary indicators).

As conservation agricultural practices continue to spread, there is a need to understand how reduced tillage impacts soil microbes. Effects of no till (NT) and disk till (DT) relative to moldboard plow (MP) were investigated in a long-term experiment established on Chernozem. Results showed that conservation practices, especially NT, increased total, active and microbial biomass carbon.
