Effects of nitrogen fertilizer rate on dry matter yield, nutritive values and nitrate nitrogen of Guineagrass (Panicum maximum Jacq.) extremely late cultivar “Umaku” as a summer annual grass in a warm temperate zone

Grassland Science, Volume 72, Issue 2, Page 151-160, April 2026.
Abstract Cultivation as a summer annual grass in temperate regions of new extremely late‐maturing guineagrass cultivar “Umaku” without heading with fertilizer application entails risks of toxic nitrate nitrogen (nitrate‐N) concentration in the grass.

Calibration and evaluation of a carbon net primary productivity module based on the SIMPLE model

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract This study presents the carbon net primary productivity (CNPP) module, an implementation of the simple generic crop model (SIMPLE model) that we have extended to predict aboveground and belowground biomass production and carbon assimilation. The goal for this module is to predict biomass inputs at and below the soil surface, during and at the ...

The Crop Feeding Behavior of Rhesus Macaques in a Forest‐Farm Mosaic in Central Nepal: Implications for Human–Wildlife Coexistence

American Journal of Primatology, Volume 88, Issue 3, March 2026.
Rhesus macaques in Nepal fed on crops for a longer duration and caused more crop damage when the foraging party was larger. Farmer interventions failed to reduce the duration of crop feeding and the amount of crop damage. ABSTRACT Human‐driven habitat change is forcing nonhuman primates to exploit anthropogenic landscapes, resulting in primate crop ...

Estimating the botanical composition of bahiagrass–rhizoma peanut pastures using aerial multispectral imagery and deep learning

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Estimating the botanical composition in mixed pastures is challenging due to resource‐intensive sampling methods overlooking grassland spatial variability. We aimed to (I) classify bahiagrass (Paspalum notatum Flügge) and rhizoma peanut (Arachis glabrata Benth.) in grass–legume pastures using aerial multispectral imagery and machine learning, (

Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters
