Carbon and nutrient stocks of tea plantations differing in age, genotype and plant population density [PDF]

, 2008
Tea (Camellia sinensis L.) is a perennial evergreen shrub managed intensively for continuous growth of young shoots. Most tea plantations were established at the expense of native forest. Change in carbon (C) and nutrient (nitrogen, phosphorus, potassium

The Effect of Humic Acid on Productivity and Nitrogen Uptake in Kangkong (Ipomoea reptans Poir.)

Jurnal Ilmu Pertanian Indonesia, 2020
An uncertain climate and infertile soils are factors that cause fluctuations in crop yields. In addition, improper application of fertilizers causes kangkong plants to not absorb nutrients optimally. The application of humic acid as a biostimulant can be

Lettuce (Lactuca sativa) productivity influenced by microbial inocula under nitrogen-limited conditions in aquaponics.

PLoS ONE, 2021
The demand for food will outpace productivity of conventional agriculture due to projected growth of the human population, concomitant with shrinkage of arable land, increasing scarcity of freshwater, and a rapidly changing climate.

Sensitivity of tropical woodland savannas to El Niño droughts [PDF]

Biogeosciences
The 2015–2016 El Niño event led to one of the hottest and most intense droughts for many tropical forests, profoundly impacting forest productivity. However, we know little about how this event affected the Cerrado, the largest savanna in South America ...

Root traits contributing to plant productivity under drought

Frontiers in Plant Science, 2013
Geneticists and breeders are positioned to breed plants with root traits that improve productivity under drought. However, a better understanding of root functional traits and how traits are related to whole plant strategies to increase crop productivity

Simulating Dynamic Roots in the Energy Exascale Earth System Land Model

Journal of Advances in Modeling Earth Systems, 2019
Roots are important contributors to plant development, functioning to provide nutrients and water for plant growth. However, roots and their functions are often simplified in Earth system models, which limit the feedback of root foraging strategy on ...
