Biogas slurry change the transport and distribution of soil water under drip irrigation Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-14 Haitao Wang, Xuefeng Qiu, Xiaoyang Liang, Hang Wang, Jiandong Wang
Biogas slurry (BS), waste water of energy production, holds potential as both an irrigation water resource and a liquid fertilizer source. Typically combined with water and mineral fertilizer at specific ratios, BS is applied in fields with drip irrigation systems to enhance crop growth. However, the soil water infiltration process with BS drip irrigation remains poorly understood, mainly owing to

Localizing agricultural impacts of 21 century climate pathways in data scarce catchments: A case study of the Nyando catchment, Kenya Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-14 Katoria Lekarkar, Albert Nkwasa, Lorenzo Villani, Ann van Griensven
Climate change is projected to increase the volatility of agricultural productivity within the Sub-Saharan Africa region. However, current knowledge of climate change impacts in this region is largely derived from coarse-grid global datasets that lack sufficient detail for local applications. The derived impacts are thus generalized across large spatial scales, with a limited representation the differential

Groundwater impacts of adding carrot to corn-peanut rotations in North Florida Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-10 Dogil Lee, Jason Merrick, Sagarika Rath, Michael Dukes, David Kaplan, Wendy Graham
The Upper Floridan aquifer underlying the Suwannee River Basin in Florida has experienced increased groundwater pumping and nitrate leaching over the last half century resulting in violation of water quantity and quality standards, largely due to row crop production. Increasingly carrot is being added as a winter cash crop to the traditional corn-peanut rotation in the region which may further increase

Exploring key factors driving farm-level seasonal irrigation water usage with Bayesian hierarchical modelling Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-09 Zitian Gao, Danlu Guo, Dongryeol Ryu, Andrew W. Western
Farm-level seasonal irrigation water usage is often highly variable across time and space in an irrigation district. Identifying the driving factors of this variation can help researchers and managers understand the underlying efficiency of water usage, identify the sources of water waste and develop best irrigation practices to facilitate the development of more efficient and sustainable irrigated

Application of machine learning approaches in supporting irrigation decision making: A review Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-09 Lisa Umutoni, Vidya Samadi
Irrigation decision-making has evolved from solely depending on farmers’ decisions taken based on the visual analysis of field conditions to making decisions based on crop water need predictions generated using machine learning (ML) techniques. This paper reviews ML related articles to discuss how ML has been used to enhance irrigation decision making. We reviewed 16 studies that used ML approaches

Effects of different irrigation scheduling methods on physiology, yield, and irrigation water productivity of soybean varieties Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-07 Ana Carolina Ferreira França, Rubens Duarte Coelho, Alice da Silva Gundim, Jéfferson de Oliveira Costa, Carlos Alberto Quiloango-Chimarro
An adequate irrigation schedule can result in significant water savings and improved crop yields, especially in large areas such as commodity crops. However, insufficient information is available regarding soybean crops in terms of irrigation scheduling methods and their interaction with irrigation water productivity (IWP) for different soybean varieties. The objective of this study was to quantify

Adjusting sowing window to mitigate climate warming effects on forage oats production on the Tibetan Plateau Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-07 Qianhu Ma, Yongliang You, Yuying Shen, Zikui Wang
Adjusting the sowing date represents an effective strategy to mitigate the adverse effects of climate change on crop production across the world. However, its effect on oats () forage production on the Tibetan Plateau is still unclear. This study aimed to determine the optimal sowing window for forage oats in the semi-arid area of the Tibetan Plateau by assessing forage yield and water productivity

Combined effects of rain-shelter cultivation and deficit micro-sprinkler irrigation practice on yield, nutrient uptake, economic benefit and water productivity of Panax notoginseng in a semi-arid region of China Agric. Water Manag. (IF 6.7) Pub Date : 2024-02-07 Zhennan Zang, Xiaofan Zhang, Tianqi Mu, Leilei Yao, Chunwei Ji, Qiliang Yang, Jiaping Liang, Na Li, Haidong Wang, Jinjin Guo, Ling Yang
The excessive rainfall and irrigation amount in the facility herbal medicine production system (FHmPS) in China leading to a severe root rot disease of , which endangers root yield and quality, compromise economic profit and waste resources. Therefore, the objective of our research was to seek optimal irrigation and cultivation management strategy for FHmPS to improve production and economic benefit
