Abstract:
... The final yield of agricultural products depends on the effective factors during the growing season of plants, especially the size of soil aggregates and proper size distribution of aggregates. Therefore, it is very important to select appropriate tillage implement and to provide a suitable seedbed in terms of aggregate size with the least energy consumption. It is a new idea to use paraplough and ...

Abstract:
... Nowadays, the advanced comprehensive utilization and the complete prohibition of burning fully covered straws in croplands have become increasingly important in agriculture engineering. As a kind of direct straw-mulching method in China, conservation tillage with straw smashing is an effective method to reduce pollution and enhance fertility. In view of the high straw-returning yields, complicated ...

Abstract:
... The cover-management factor (C-factor) of the Universal Soil Loss Equation (USLE) is the most important factor for estimating the effects of farming practices or agricultural policy measures on soil loss rates. This study, conducted in Switzerland from 1987 to 2017, assessed the impact of mitigation measures on arable land by comparing modelled C-factor values and measured soil losses. C-factor va ...

Abstract:
... Drought is considered one of the key barriers influencing wheat production, and various adaptation schemes are practiced globally to mitigate drought impacts. However, it is difficult to precisely assess the performances of drought mitigation measures, especially when multiple measures are implemented simultaneously. Here, a remote sensing-based agricultural drought-affected area change index (ADA ...

Abstract:
... Straw incorporation is a critical conservation tillage measure that effectively reduces slope runoff and sediment. This study used laboratory experiments to examine the combined effects of the straw length and incorporation rate on reducing runoff and sediment, under straw incorporation. The experiments involved three wheat straw lengths (3–5, 8–10, and 13–15 cm) and four incorporation rates (1.5, ...

Abstract:
... In the context of climate change, agricultural cultivation, as one of the most vulnerable sectors, is under threat. Extreme weather and climate conditions have caused a series of problems, such as yield loss, more serious pests and diseases, and declining biodiversity. Conservation tillage is considered a potential method to improve climate resilience, yet the intrinsic mechanism of how conservati ...
... In conservation tillage (CT) systems, the implement should be able not only to loosen the soil but also to keep plant residues on the soil surface. The present study investigates the suitability of bent-share ploughs for CT whose effects on improving soil physical properties at low energy costs have already been established. For the purposes of this study, bent-share ploughs of two different share ...

Abstract:
... The traditional fertilizer application methods have serious problems of environmental pollution and soil degradation due to low utilization rates in the Huang–Huai–Hai Plain of China. In this study, the conservation tillage strip-hole layered fertilization method was proposed and a precision strip-hole layered fertilizer subsoiler was designed. To meet the requirements for deep tillage strip-hole ...

Abstract:
... Site-specific weed control offers a great potential for herbicide savings in agricultural crops without causing yield losses and additional weed management costs in the following years. Therefore, precision weed management is an efficient tool to meet the EU targets for pesticide reduction. This review summarizes different commercial technologies and prototypes for precision patch spraying and spo ...
... Understanding the response of microbial-derived nitrogen (N) in the soil to N availability is essential for optimizing N fertilizer management. In this study, based on amino sugar biomarker assays in a conservation tillage agroecosystem, we evaluated the effects of 3-year fertilizer N reduction (reduced from 240 to 190, 135, 0 kg N ha⁻¹) and crop residue return on microbial necromass N dynamics. T ...
... Cereals in Europe are mainly grown with intensive management. This often leads to the deterioration of the physical properties of the soil, especially increasing bulk density due to heavy machinery traffic, which causes excessive soil compaction. Controlled traffic farming (CTF) technology has the potential to address these issues, as it should be advantageous technology for growing cereals during ...
... Soil available nitrogen (AN) is highly related to crop growth and N leaching in the agricultural environment, but the heterogeneity of AN and its driving mechanisms have not been clarified in the Mollisols region. In this study, a total of 610 soil samples were collected from 0‒60 cm soil depths in a small watershed (1.86 km²) of northeastern China, and both traditional statistics and geostatistic ...
... A Palmer amaranth (Amaranthus palmeri S. Watson) population (KCTR: KS Conservation Tillage Resistant) collected from a conservation tillage field was confirmed with resistance to herbicides targeting at least six sites of action, including 2,4-D. The objectives of this research were using KCTR A. palmeri to investigate (1) the level of 2,4-D resistance, (2) 2,4-D absorption and translocation profi ...

Abstract:
... Lakes and ponds play a disproportionate role in retaining sediment, carbon, nitrogen, and phosphorus, potentially mitigating negative environmental effects. However, how sequestration rates change over a pond’s lifetime, and how rates are affected by watershed land use practices remains poorly characterized. In this study, we quantified sediment, carbon, nitrogen, and phosphorus burial rates, and ...
... Considering the current threatening conditions of climate change, Climate Smart Agriculture (CSA) aims to improve the soil health and its organic carbon stocks by encouraging soil carbon sequestration through conservation practices in agricultural lands. However, the effects of these practices differ due to diverse climatic scenario, soil characteristics and management system. To identify the suit ...

Abstract:
... Research has revealed that summer fallow sowing improves the water use efficiency (WUE) and grain yield of winter wheat. However, wheat yields differ yearly with crop management. A field experiment over 8 years was established in the Loess Plateau to determine the role of precipitation and soil water storage in wheat yield formation under conservation tillage. The average WUE values were 7.8, 11.0 ...
... Poultry litter is generated in large quantities throughout the southeastern United States and is an excellent nutrient source for increasing crop yields. However, surface applications result in nutrient losses to air, soil, and water. Subsurface banding poultry litter is a promising technology for reducing nutrient losses to surface and groundwater, but information is needed on optimum crop seedin ...
