Abstract
Introduction
Satellite-sourced data have become a valuable resource for precision agriculture because they provide crucial insights into various parameters that are essential for effective crop management. An array of practical agricultural tools provides comprehensive data for assessing crop biomass, soil conditions, and plant stress symptoms, predicting yields, and performing other functions. Satellite data, when combined with in situ data from different sources, can significantly enhance biomass and yield estimations.
Material and Methods
The ability of the “PROcesses of radiation, Mass and Energy Transfer” (PROMET) model to predict crop biomass and grain yield and to optimize nitrogen fertilization during the vegetation period was investigated. Field trials were conducted to assess the accuracy and limitations of biomass and yield predictions.
Results and Conclusion
The predicted yields were sufficiently accurate on a whole-field basis, and site-specific values showed strong correlations. In additional field trials with different fertilization strategies, the highest yield and nitrogen efficiency were observed for the PROMET-based strategy. Additional experiments with different crops and greater durations are needed to draw a more reliable conclusion.
导言卫星数据已成为精准农业的宝贵资源,因为它们提供了对有效作物管理至关重要的各种参数的重要见解。一系列实用的农业工具为评估作物生物量、土壤条件和植物胁迫症状、预测产量以及执行其他功能提供了全面的数据。材料与方法 研究了 "辐射、质量和能量传递过程"(PROMET)模型预测作物生物量和谷物产量以及优化植被期氮肥施用的能力。进行了田间试验,以评估生物量和产量预测的准确性和局限性。在采用不同施肥策略的其他田间试验中,基于 PROMET 的策略产量和氮效率最高。要得出更可靠的结论,还需要对不同作物和更长的施肥期进行更多试验。
