A source-side trait-mediated framework for dynamic maize yield prediction using UAV multispectral imagery

Dynamic in-season maize yield prediction is essential for cultivation management and precision decision-making. However, traditional yield prediction models based on vegetation indices often lack physiological interpretability, and integrating multitemporal dynamic information wi...

Design and Testing of a Gravity-Constrained Fertilizer Guide Tube for Stable Fertilizer Cluster Movement

Fertilizer clusters tend to lose their agglomerated state upon ground contact, which reduces fertilizer use efficiency. To address this, we designed a gravity-constrained fertilizer guide tube. Based on the principle of minimum friction, we designed a trapezoidal groove. By analy...

Mitigation of ammonia and nitrous oxide emissions and cutdown of composting cycle during Enteromorpha prolifera composting with the co-addition of attapulgite and biochar

Abstract Since 2007, annual blooms of the green macroalga Enteromorpha prolifera have occurred in China’s coastal waters, posing serious threats to local aquaculture and ecological environment. Composting is an ideal way for managing E. prolifera waste. This study explored how at...

Multi-Algorithm Hierarchical Minimum Data Sets for Soil Quality Assessment in the Black Soil Region of Northeast China: A Case Study in Keshan County

The Northeast black soil region is a major grain-producing area in China, where county-scale assessment of topsoil quality is essential for soil conservation and provides a potential indicator framework for regional soil quality monitoring. In this study, 500 composite cultivated...
