SoilWaterNow: Soil water nowcasting for mapping plant available water (PAW) across paddocks for improved on-farm decision-making

A Soil Moisture Profile Response-Driven Framework for Estimating Irrigation Water Use Under Spatial Allocation Constraints

Accurate estimation of irrigation water use is essential for agricultural water accounting and water-resource allocation in large irrigated districts, yet existing statistics are usually available only as aggregated administrative totals and cannot adequately characterize seasonal and spatial differences in field-appli...

Small-Sample Prediction and Uncertainty Assessment of Soil Organic Carbon Content in Cropland of the Liaohe Plain Based on the TabPFN Model

Soil organic carbon (SOC) is a key indicator of cropland quality, soil fertility, and the carbon sequestration potential of agroecosystems. Accurate characterization of its spatial distribution is essential for black soil conservation and regional soil carbon management. However, regional-scale SOC prediction is often...

Spatial Variability and Management Zone Delineation in Cereal–Legume Forage Mixtures Using Apparent Electrical Conductivity and NDVI Under No-Till Conditions

Cereal–legume forage mixtures provide sustainable agronomic and environmental benefits for arid Mediterranean agricultural systems, but their productivity is often limited by within-field soil spatial variability. Site specific management practices are required to address the yield gaps. This study aimed to identify ma...

Assessing the reliability of remote sensing-based evapotranspiration models for enhanced water management under center-pivot irrigation system in arid region. Case study: East Oweinat, Egypt

Modeling Cereal Rye Cover Crop Impacts on Soil Erosion, Nutrient Losses, and Crop Yields Across U.S. Corn and Soybean Production Areas

Cover crops are increasingly promoted to improve soil health, reduce nutrient losses, and enhance water quality, yet their large-scale performance across diverse climatic and soil conditions remains insufficiently quantified. We hypothesized that cereal rye cover crop adoption would reduce sediment and nutrient losses,...

A Shiny-Based Decision-Support Tool for Rainwater Harvesting, Tank Storage, and Crop Allocation Planning in Small-Scale Horticultural Gardens

Harvested rainwater can support small-scale horticulture, but its value depends on the joint timing of rainfall, crop demand, capture area, and finite storage. We developed RainHarvest Garden Optimizer, an open-source R/Shiny decision-support application that couples crop phenology and crop-water requirements with rain...
