Database for spring, summer and fall-planted cover crop performance across the state of Nebraska

This repository contains raw datasets from multi-year cover crop variety trials conducted across Nebraska to evaluate biomass production, plant height, nutrient content, and soil health parameters. Trials were established in multiple ecoregions, including UNL research stations and private farms, to assess cover crop performance under diverse conditions. The data includes cover crop biomass, soil properties, root measurements, and vegetative indices, along with metadata on trial locations and management practices. This repository supports researchers, agronomists, and stakeholders in optimizing cover crop management and soil health. The structured datasets facilitate reproducibility and contribute to developing Nebraska-specific cover crop growth models and management recommendations.

本数据集仓库收录了在内布拉斯加州（Nebraska）开展的多年覆盖作物品种试验原始数据集，用于评估覆盖作物的生物量生产、株高、养分含量及土壤健康相关参数。试验在多个生态区域布设，涵盖UNL（内布拉斯加大学林肯分校，University of Nebraska-Lincoln）试验站及私人农场，以评估覆盖作物在多样环境中的生长表现。本次数据集包含覆盖作物生物量、土壤属性、根系测量数据及植被指数，同时附带试验点位与管理措施的元数据。本仓库可为研究人员、农学家及相关利益相关者优化覆盖作物管理与土壤健康管控提供支撑。结构化的数据集便于研究成果可复现，同时有助于构建适配内布拉斯加州的覆盖作物生长模型及管理建议。
