A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.
WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

An extensive field trial was established on a fly ash deposit (1) to evaluate whether the inoculation with arbuscular mycorrhizal fungi ( AMF ) and/or ectomycorrhizal fungi ( EcMF ) improves growth and survival of 13 planted tree species…

Abstract Soil conditioners, such as biochar and zeolites, may play an important role in agriculture if they increase nutrient use efficiency, in particular, that of phosphorus (P), due to the depletion of phosphate rocks from which…

Abstract The effectiveness of multiple small doses of the nitrification inhibitor dicyandiamide (DCD) to decrease denitrification under warm moist conditions was tested in a 1‐year field trial on a grazed dairy pasture. DCD was applied…

This randomized clinical trial evaluated the effect of upon-arrival intranasal vaccination against bovine coronavirus (BCoV) on pneumonia risk in a beef-on-dairy veal production system. Secondary objectives were to assess the effect…

Field trials were conducted to define several parameters associated with adding LEDs to monitoring traps for codling moth (CM), Cydia pomonella (L.), using both a sex pheromone lure (PH1X) and a non-pheromone lure (CM4K). Traps with LEDs…

Enhanced rock weathering (ERW) is a CO 2 removal technology that involves spreading finely ground silicate rock on fields. The chemical weathering of this rock powder removes atmospheric CO 2 in the form of bicarbonate ions and secondary…
Horita V, Yuan L · 2026 · Preprint
Commercial inoculants based on associative diazotrophs and methylotrophic bacteria, and bios-timulant programs, are marketed for broad use in cereal and fiber production, yet most field deployment occurs over already adequate mineral…

This study investigates the impact of seeding rate, cultivar architecture, and fungicide application on soybean canopy penetration, disease severity, and yield. Field trials conducted in Iowa in 2022, 2023, and 2025 included two soybean…

The objective of the study was to determine modifications in the content of available nutrients, organic carbon, total nitrogen and mineral forms of nitrogen occurring under the effect of long-term mineral and mineral-organic fertilization. The experiments were carried out on two fields between 1998 and 2001. They covered the fourth rotation of a long-term field trial established in 1986. On grey-brown podzolic soil formed from loamy clay, the following crops were grown in rotation: sugar beet, spring barley, maize and spring wheat. The soil analyses carried out prior to the tests showed that

Potato is an important food crop with high water-use-efficiency but low drought tolerance. The bottleneck in drought tolerance breeding is phenotyping in managed field environments. Fundamental research on drought tolerance is predominantly done in container-based test systems in controlled environments. However, the portability of results from these systems to performance under field conditions is debated. Thus, we analyzed the effects of climate conditions, container size, starting material, and substrate on yield and drought tolerance assessment of potato genotypes compared to field trials.

Lower canopy temperature (CT), resulting from increased stomatal conductance, has been associated with increased yield in wheat. Historically, CT has been measured with hand-held infrared thermometers. Using the hand-held CT method on large field trials is problematic, mostly because measurements are confounded by temporal weather changes during the time requiredto measure all plots. The hand-held CT method is laborious and yet the resulting heritability low, thereby reducing confidence in selection in large scale breeding endeavours.We have developed a reliable and scalable crop phenotyping m
