Interactions between fertilizer nitrogen and soil nitrogen — the so-called ‘priming’ effect

open access: yes, 1985
Experiments with 15N labelled fertilizers often show that plants given fertilizer N take up more N from the soil than plants not given N—the priming effect or ‘added nitrogen interaction’(ANI).

Plant Metabolites Screening Identifies 7‐epi‐10‐Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization

open access: yesAdvanced Science, EarlyView.
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

The Effect of Soil Microbial Residues-Mediated Nitrogen Conservation and Supply during the Growing Season on Nitrogen Uptake by Wheat

open access: yesAgronomy
Microbial residue nitrogen can indicate soil quality and is crucial for soil nitrogen retention and supply. However, it is still unclear how the dynamic changes in soil microbial residue nitrogen affect crop nitrogen uptake in agricultural practice ...

FERTILIZER DEMAND FUNCTIONS FOR SPECIFIC NUTRIENTS APPLIED TO THREE MAJOR U.S. CROPS [PDF]

open access: yes
Several past studies used time series data to estimate price elasticities of demand for fertilizer or nutrient use on all crops in the United States or by region. In this study, demand functions for nitrogen, phosphorous and potassium applied per acre of

Optimized Land–Water Management Expands Afforestation Potential Under Land and Human Water‐Use Constraints

open access: yesAdvanced Science, EarlyView.
Human water demand constrains China's feasible afforestation potential more strongly than is commonly recognized, and future climate change further intensifies this limitation. Integrating land‐use optimization with water‐saving measures substantially expands feasible afforestation area and associated carbon sinks, revealing a practical pathway to ...

Metal–Phenolic Complexation Governs Soil Mineral Crystallinity to Enhance Crop Growth

open access: yesAdvanced Science, EarlyView.
A coordination‐driven, coprecipitation approach is presented to obtain polyphenolic‐incorporated minerals with tunable crystallinity, offering insights into how plants may influence soil mineral structures. Soil minerals can incorporate polyphenolic secondary metabolites and enhance plant nutrition by facilitating the formation of amorphous metal ...

The Effect of Combined Use of Nitrogen Fertilizer and Seaweed on Yield Components and Grain Yield of Rice (Oryza sativa L.) Variety Hashemi [PDF]

open access: yesپژوهشهای زراعی ایران
IntroductionRice (Oryza sativa L.) is the staple food of half of the world's population, providing 21% of the energy and 15% of the protein of residents of rice-growing regions. Compared to other essential elements, rice needs more nitrogen.

Identification of genotypic variation for nitrogen response in potato (Solanum tuberosum) under low nitrogen input circumstances [PDF]

open access: yes, 2009
Nitrogen is an essential nutrient for crop growth. The demand for nitrogen in the potato crop is relatively high. However, in organic farming nitrogen input is rather limited, compared with conventional farming.

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

open access: yesAdvanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

REGULATION OF NITROGEN POLLUTION: TAXES VERSUS QUOTAS [PDF]

open access: yes
This paper investigates the effects of first-best policies to regulate nitrogen application. Some nitrogen fertilizer is applied ex ante before a random rainfall, but sidedressed nitrogen may be applied ex post.
